1 Safety Precautions
Your lawnmower should be used with due care and attention. Symbols have
therefore been placed on various parts of the machine to remind you of the
main precautions to be taken. Their meaning is explained below. You are also
asked to read the safety precautions listed below.
1.
Warning: Read the
instruction manual
before using the
machine.
2.
Beware of thrown
objects: Keep other
people at a safe
distance whilst working.
3.
Warning: Disconnect
the spark plug cap
before carrying out any
repairs or
maintenance.
4.
Beware of cutting:
Moving blades. Do not
put hands or feet near
the blades.
The following safety precautions must be observed at all times. Please read
them very carefully.
TRAINING:
1. Read the instructions carefully. Get familiar with the controls and proper use
of the equipment. Learn how to stop the engine quickly.
2. Only use the lawnmower for the purpose for which it was designed, i.e. for
cutting and collecting grass. Any other use can be hazardous, causing
damage to the machine. Examples of improper use may include, but are not
limited to:
• Transport of people, children or animals on the machine;
• Being transported by the machine;
• Using the machine to tow or push loads;
• Using the machine for leaf or debris collection;
• Using the machine to trim hedges, or for cutting vegetation other than
grass;
• Use of the machine by more than one person;
• Using the blade on surfaces other than grass.
3. Never allow children or people unfamiliar with these instructions to use the
lawnmower. Local regulations may restrict the age of the operator.
4. Never use the lawnmower:
• When people, especially children, or pets are nearby;
• If the operator has taken medicine or substances that can affect his ability
to react and concentrate.
5. Remember that the operator or user is responsible for accidents or hazards
occurring to other people or their property.
6. Never put your hands, feet or any implement under the cutter deck or inside the
rear discharge chute. The cutter blade will continue to rotate for some time after
the engine is switched off.

RV40, V35
PREPARATION:
1. While mowing, always wear sturdy footwear and long trousers. Do not
operate the equipment when bare foot or wearing open sandals. Avoid
loose clothing that may snag on moving parts.
2. Thoroughly inspect the area where the equipment is to be used and remove all
objects which may be thrown by the machine or damage the cutter assembly and
the engine (stones, sticks, metal wire, bones, etc).
3. WARNING: DANGER! Engine fuel is highly inflammable:
• Store fuel in containers specifically designed for this purpose;
• Refuel using a funnel and outdoors only – do not smoke while
refuelling or whenever handling the fuel;
• Add fuel before starting the engine – never remove the cap of the fuel
tank or add fuel while the engine is running or when the engine is hot;
• If fuel is spilled, do not attempt to start the engine but move the machine
away from the area of the spillage and avoid creating any source of
ignition until the fuel has evaporated and the vapour has dispersed;
• Replace all fuel tanks’ and retainers’ caps securely.
4. Substitute faulty silencers. Never use the machine without a silencer.
5. Before use, always inspect the machine, especially the condition of the
blades, and check that the screws and cutting assembly are not worn or
damaged. Replace worn or damaged blades and screws in sets to preserve
balance.
6. Before mowing, attach the discharge opening guards (grass-catcher or stoneguard).
OPERATION:
1. Do not operate the engine in a confined space where dangerous carbon
monoxide fumes can collect.
2. Mow only in daylight or good artificial light.
3. If possible avoid operating the equipment on wet grass.
4. Always be sure of your footing on slopes.
5. Walk, never run and do not allow yourself to be pulled along by the lawnmower.
6. Mow across the face of slopes, never up and down.
7. Exercise extreme caution when changing direction on slopes.
8. Do not mow on slopes of more than 20 degrees.
9. Exercise extreme caution when pulling the lawnmower towards you.
10. Stop the blade if the lawnmower has to be tilted for transportation when crossing
surfaces other than grass, and when transporting the lawnmower to and from the
area to be mown.
11. Never operate the lawnmower with defective guards, or without safety devices,
such as the stone-guard and/or grass-catcher, in place.
12. Do not change the engine governor settings or over-rev the engine.
13. On power-driven models, disengage the drive clutch before starting the engine.
14. Start the engine carefully, following the instructions and keeping feet well away
from the blade.
15. Do not tilt the lawnmower when starting the engine. Start the engine on a flat
surface that is free of obstacles and tall grass.
16. Do not put your hands or feet near or under rotating parts. Keep clear of the
discharge opening at all times.
17. Never pick up or carry a lawnmower while the engine is running.

RV40, V35
18. Stop the engine and disconnect the sparkplug wire:
• Before carrying out any work underneath the cutting deck or before
unclogging the chute;
• Before checking, cleaning or working on the lawnmower;
• After striking a foreign object – inspect the lawnmower for damage and
make repairs before restarting and operating the lawnmower;
• If the lawnmower begins to abnormally vibrate (immediately look for the
cause of the vibrations and take for necessary controls to a specialist
centre).
19. Stop the engine:
• Whenever you leave the lawnmower unattended – remove the key from
models with electric starters;
• Before refuelling;
• Every time you remove or replace the grass-catcher;
• Before adjusting the grass cutting height.
20. Reduce the throttle before turning off the engine and (if fitted) turn the fuel off
when you have finished mowing following the instructions in the engine
handbook.
21. When mowing, always keep a safe distance from the rotating blade. The
distance is the length of the handle.
MAINTENANCE AND STORAGE:
1. Keep all nuts, bolts and screws tight to be sure the equipment is in safe working
condition. Regular maintenance is essential for safety and performance.
2. Never store the equipment with fuel in the tank inside a building where vapour
may reach a flame or a spark or a source of extreme heat.
3. Allow the engine to cool before storing in an enclosed space.
4. To reduce the fire hazard, keep the engine, exhaust silencer, battery
compartment and fuel storage area free of grass, leaves, or excessive
grease. Do not leave containers with grass cuttings in rooms.
5. Check the stone-guard and the grass-catcher frequently for wear and
deterioration.
6. If the fuel tank has to be drained, this should be done outdoors and when the
engine is cool.
7. Wear strong work gloves when removing and reassembling the blade.
8. Keep the blade balanced during sharpening. All operations on the blade
(dismantling, sharpening, remounting balancing, and/or replacing) require a
certain familiarity and special tools. For safety reasons, these jobs are best
carried out at a specialized centred.
9. For safety reasons, never use the machine when it has worn or damaged
parts. Parts are to be replaced and not repaired. Use genuine spare parts.
Parts that are not of the same quality can damage the equipment and impair
your safety.
TRANSPORTATION AND HANDLING:
1. Whenever the machine is to be handled, raised, transported or tilted you must:
• Wear strong working gloves;
• Grasp the machine at the points that offer a safe grip, taking account of
the weight and its distribution;
• Use an appropriate number of people for the weight of the machine and

2 Fuel, Oil, Air Filter and Spark Plug Requirements
FUEL – these are 4-stroke petrol engines. The correct fuel is ordinary unleaded
petrol.
NOTE: The RV150 and SV150 engines have dual fuel capability and so biofuels may be used without additional adjustment to the engine.
Fuel capacity:
• V35 engine – 0.8 litre
• RV and SV 150 engines – 0.8 litre
• RV40 engines – 0.8 litre
Do not overfill the fuel tank – fill the tank to approximately 5mm below the
inner edge of the filler neck.
OIL – the correct oil to use is Mountfield MX855 oil, or a 4-stroke SAE 30 or
10W-30 multi-viscosity oil. DO NOT mix oil with the fuel. The dipstick shows
the minimum and maximum levels. The engine holds 0.6 litre of oil. NB
Wipe the dipstick, then fully replace it by screwing it in, now withdraw it to
gain an accurate reading.
The use of multi-viscosity oils in hot temperatures will result in a higher than
normal oil consumption. It is important, therefore, to check the oil level more
frequently.
Do not mix oils of different brands and features.
Do not over-fill with oil. Over-filling may cause smoking or contamination of
the spark plug and/or air filter.
Please dispose of old fuel and used engine oil in a manner that is compatible
with the environment
AIR FILTER for RV150, SV150, RV40 and V35 engines – these engines use a
cleanable (warm soapy water) sponge air filter.
SPARK PLUG – the following sparkplugs are the correct specification:
RV150, V35, RV40, V35 engines
•
Champion: QJ19LM
SV150 (year 2006) engines
•
Champion: J17LM or
RJ19LM (both screw-off
cap, and the cap needs
to be screwed off before
fitting)
The spark plug gap in all cases should be 0.6 – 0.8mm or 0.03” (30/1000)

3 Routine Engine Maintenance
Regular and careful maintenance is essential to preserve the original
performance and safety level of the engine. Always store the mower in a dry
place.
TESTING FOR A SPARK (this job requires 2 people)
1. Stand the machine on a firm surface and set the
height adjusters to the lowest setting for added
safety.
2. Remove the H.T. lead (1 in the diagram) – a
push/pull fit.
3. Unscrew the spark plug (2 in the diagram) with a
genuine spark plug spanner.
4. Fit the plug back into the end of the HT Cap and rest
it against the engine block (hold only the black
insulation lead).
5. The second person can now hold in the Operator
Presence Control (OPC) and pull the engine cord.
You should see a spark jump across the end of the
plug. NOTE: The blade will turn when doing this.

Champion: QJ19LM
SV150 (year
2006
Champion: J17LM or RJ19LM
(both screw-off cap, and the
cap needs to be screwed off
before fitting)
The spark plug gap for all
these Mountfield engines
should be 0.6 – 0.8mm or
30
0.03” (that is /1000)
DRAINING FUEL:
We advise that the engine should be drained of fuel before storage for more than 30
days. One should only buy fuel in quantities that can be used up within a few weeks.
How to drain the fuel is explained in sub-section A of Section 4 Starting the Engine.
Alternatively, because these engines have a gravity-feed, the engine may be allowed
to run until it runs out of petrol.
Please dispose of old fuel and used engine oil in a manner that is compatible
with the environment

CHANGING ENGINE OIL
Check the engine oil before each use.
Engine Oil
These small four stroke engines hold up to 0.6 litres
of oil (1.2 Pints). Any oil shortages can cause
premature wear or serious damage to the engine.
So too will using the incorrect grade of oil. NB
Wipe the dipstick, then fully replace it by screwing it in,
now withdraw it to gain an accurate reading.
• Mountfield MX855
• SAE30 lawnmower oil
• 10W-30 oil
Mountfield MX855 four stroke oil is readily available
through either the B&Q chain of retailers or through our
own comprehensive dealer network.
If you are unable to obtain the correct oil, use either an
SAE30 or a 10W-30 grade of oil. These oils are
generally only found in the larger DIY stores in the
gardening department or at a garden centre or
lawnmower specialist
The oil should be changed on all new engines after
approximately 5 hours of operation. It should then be
changed every 50 hours of operation, or once a season.
Oil capacity is 0.6 litre
Mountfield MX855 four stroke oil
is readily available through
either the B&Q chain or through
our own dealer network.
Before changing the oil, run the engine for a few
minutes to warm the engine oil. This allows it to run
more freely and to carry out any sediment with it.
To drain oil from the oil fill tube, run the engine to warm the oil. Remove the HT lead
and grass catcher assembly. Undo the oil fill dip stick and make sure a suitable tray
is in place to catch the oil. Tilt the machine backwards onto the rear wheel closest
to the oil fill (three wheels will be clear of the ground). As the angle increases the
oil will pour out of the fill and into the tray. Once completed, stand the machine on
level ground and refilled in accordance with the operating instructions.
Please dispose of old fuel and used engine oil in a manner that is compatible
with the environment

4 Starting the Engine
The correct way to start the mower:
Check the engine oil, and there is sufficient clean/fresh petrol in the fuel tank.
1. Ensure the machine is on a firm level surface
(path, patio or short grass). Check the underside
is clear from old lawn debris. If you have to tilt
the mower, do this backwards only. Before
checking the underside, make sure to remove
the HT Cap (sparkplug cap).
2. Check the H.T. lead (spark plug cap) is correctly
fitted to the spark plug.
3. Set the throttle to CHOKE before starting (this
may be necessary even when the engine is
warm).
4. Check the OPC lever (it may be marked STOP, or
it may be a red handle at the left side of the main
handle bar) is held against the main handle bar
when starting and using the mower. Pull the cord
to start the engine, and once running set the
throttle to FAST.

A:
Fuel requirements:
These
engines run
on ordinary
un-leaded
fuel. The fuel
tank holds 0.8
litres.
Stale fuel or
build-ups in
the fuel tank
are most
common
when the
mower has
been stored
for a period of
time (e.g. over
the winter
period)
The fuel tank on these gravity-fed engines breathes through the
thread on the fuel cap. An air lock may be created if the fuel cap is
too tight……this would cause the engine to cut out. The remedy is
to remove the fuel cap to let air back into the tank, replace the cap
and tighten it just finger-tight.
Because fuel can separate over a period of time we advise that the
engine be drained of fuel before storage for more than 30 days.
One should only buy fuel in quantities that can be used up within a
few weeks.
When emptying stale fuel from the engine place the mower on
a solid surface, or patch of gravel or similar (fuel spillage may
kill the lawn/stain a patio).
To drain the fuel, remove the H.T. lead (spark plug cap) for safety,
remove the air filter (for visibility), and tilt the mower BACKWARDS.
Viewed from the front, to the left of the spark plug and to the right
of where the air filter was you will see the float bowl on the
carburettor. A bolt holds the bowl in place on the very bottom, but
on an angle slightly closer to you is another bolt with a red washer.
With a 10mm spanner undo this bolt on the angle and remove it
(taking care not to lose the washer). Allow the petrol to drain
completely from the tank before replacing the bolt. Refill the tank
with fresh unleaded fuel.
NOTE: Fuel that has become contaminated will prevent these
engines from starting. Contamination can include water from
either condensation or from water that has somehow got into
the storage tanks at the garage. A service dealer may be
required to clear this.
Please dispose of old fuel and used engine oil in a manner that
is compatible with the environment

B:
Spark plug:
1. Check the H.T. lead (spark plug cap) is correctly fitted
to the spark plug and the metal cap inside the H.T.
lead cap is pointing forwards to make a good
connection with the spark plug. To test for a spark see
2-6 below.
2. Stand the machine on a firm surface and set the
height adjusters to the lowest setting for added safety.
3. Remove the H.T. lead (1 in the diagram).
4. Unscrew the spark plug (2 in the diagram) with a
genuine spark plug spanner.
5. Fit the plug back into the end of the H.T. lead (making
sure the metal cap inside the rubber cap connects
closely) and rest it against the engine block (NB hold
only the black insulation lead).
6. The second person can now hold in the Operators
Presence Control and pull the engine cord. You
should see a spark jump across the end of the plug.
Oil on the spark plug will prevent any spark. To clean oil
from the spark plug, remove and clean the spark plug
completely. ONLY USE A GENUINE SPARKPLUG
SPANNER.
With the sparkplug removed, hold in the OPC and pull the
engine over with the pull cord 6 times to eject any oil from
the spark plug hole. Replace the plug and start the
engine in the normal way. The engine may smoke at first,
but allow the engine to continue running for at least ten
minutes. The smoke will begin to dissipate. Allow to run
until the smoke clears.
NOTE: If there is no spark, change the plug. If
there is still no spark refer to a service dealer
because the coil may be faulty.

Bleeding air from the fuel supply:
If fuel is not reaching the cylinder it may be there is air trapped in the fuel supply. To
resolve this, place the mower on a solid surface, or patch of gravel or similar (fuel
spillage may kill the lawn or stain a patio), and remove the air filter.
Viewed from the front, to the left of the spark plug and to the right of where the air
filter was you will see the float bowl on the carburettor. A bolt holds the bowl in place
on the very bottom, but on an angle slightly closer to you is another bolt with a red
washer. With a 10mm spanner undo this bolt on the angle until petrol flows freely.
Re-tighten this bolt.

D:
Adjusting the micro switch:
1. Hold the OPC bar gently in to the main handle
and listen for a faint click coming from the
back right hand corner of the engine. You are
checking here for a micro-switch engaging
which allows the electrical feed to the spark
plug. If there is no audible click it may be that
the micro-switch is not fully engaged.
2. In this case, follow the OPC cable down to the
back right hand corner of the engine where
the lever moves when the OPC is depressed.
Come BACKWARDS along the bare metal
cable (2) some 8cms to where the metal
bracket (5) grips the black plastic cable
covering (directly below the fuel filler).
3. Release the plastic cable cover by
compressing the 2 lugs (X) inwards on the
plastic cable cover that are splayed out and
hold it in place. Feed the black plastic cable
cover BACKWARDS through the bracket (5).
X
4. With a pair of pliers bend the metal bracket
(5) BACKWARDS 4 mm towards the handle,
and then replace the cable in the bracket.
This will now engage the micro-switch by
pulling it further, and you should now be able
to start the mower in the normal way.

away’ (on
self-propelled
models)
A:
Re-aligning the throttle cable:
1.
From the back of the mower come around
to the side on the right. The black plastic
cover (1) you can see on the side of the
engine is the air filter.
2.
To the LEFT of the air filter there is a
vertical metal lever running up the side of
the engine (it can be felt if you put your
hand against the engine block and slide it
towards the back of the mower along the
side of the engine).
3.
From BELOW the air filter there is a black
plastic covered cable (the throttle cable)
which runs back along the side of the
engine, across the back of the mower and
then up the handle to the throttle lever.
4.
CHECK TO SEE IF THIS CABLE

METAL LEVER?
5.
If ‘YES’: Follow the cable backwards to
where it crosses over at the back of the
mower. There is a plastic loop around this
cable and another cable. Moving that
plastic loop either up or down the cable
will alter the lie of the cable and move it
away from the regulating mechanism.
This will cause the engine revs to fall to a
normal level.
If ‘NO’: See sections B and C
B:
Removing debris from the throttle linkage:
1.
From the back of the mower come
around to the side on the right. Unclip
the black plastic cover you can see on
the side of the engine – this is the air
filter. This will now enable you to see
the top of the carburettor where the
throttle linkage is to be found.
2.
Check for any leaves or twigs caught in
the throttle linkage and springs. These
can be caught as a result of cutting
beneath over-hanging shrubs.
CAREFULLY remove any caught debris
and make sure not to distort or detach
the springs or connecting links.
C:
Damage to the throttle regulator/throttle linkage, or other unspecified
throttle problems:
The mower needs to be taken to an authorised
parts/service dealer.

1.
Place the mower on a level surface (not the lawn or a good patio).
Check the oil level in the sump, top up if necessary. Check the level
of fuel in the tank and top this up (the mower once started may need
to run for up to 40 minutes). Remove the air filter assembly.
2.
The filter is located on the right hand side of the engine (viewed from
the back). The filter should be just sticky to the touch with oil. If very
oily, clean the foam filter in hot soapy water, dry and lightly oil it.
Squeeze to remove any excess oil.
3.
Remove and clean the spark plug completely. ONLY USE A
GENUINE SPARKPLUG SPANNER.
With the sparkplug removed, hold in the OPC and pull the starter cord
6 times to eject any oil from the spark plug hole.
4.
Replace the plug and start the engine in the normal way. The engine
will smoke quite badly at first, but allow the engine to continue
running for at least ten minutes. The smoke will begin to dissipate.
Never mow any grass with the air filter removed.
5.
Stop the engine and refit the cleaned and correctly-oiled air filter.
Please dispose of old fuel and used engine oil in a manner that
is compatible with the environment

NB During subsequent uses (for maybe a further 8-10 hours) the mower may
smoke a little. Droplets of oil may come from the exhaust onto the deck as
the oil is cleared from the cylinder. Simply wipe these away with an old rag.
The correct way to tip your mower is BACKWARDS.

7 Engine Cutting Out or Running Unevenly
QUICK TROUBLESHOOTING GUIDE:
Problem:
Likely Cause:
Engine hunts
• Fuel cap too tight
briefly and stops
Solution:
• Loosen cap (see A)
Engine hunts
continuously
•
•
Dirt in fuel supply
Air drawn into the engine from
a faulty manifold
•
•
Replace fuel (See B)
Refer to dealer
Engine stops
without hunting
and won’t start
again
•
Faulty spark plug or faulty
spark plug connection
•
Check for a spark (See
C)
•
Micro switch not engaging
•
Adjust (see D)
•
Faulty coil
•
Refer to dealer (see E)
A:
The fuel tank on these gravity-fed engines breathes through the thread on the
fuel cap. An air lock may be created if the fuel cap is too tight. Typically, the
engine will not re-start for a period of minutes.
SOLUTION: Remove the fuel cap to let air back into the tank, replace
the cap and tighten it just finger-tight.
NOTE: Air trapped in the carburettor may still stop the engine starting. If so,:
place the mower on a solid surface, or patch of gravel or similar (fuel spillage
may kill the lawn or stain a patio):
1. Remove the spark plug cap (for safety), remove the air filter (for
visibility), tilt the mower BACKWARDS.
2. Viewed from the front, to the left of the spark plug and to the right of
where the air filter was you will see the float bowl on the carburettor.
A bolt holds the bowl in place on the very bottom, but on an angle
slightly closer to you is another bolt with a red washer.
3. With a 10mm spanner undo this bolt until petrol flows freely to bleed
the carburettor of any trapped air. Tighten the bolt once petrol is
flowing freely, replace the spark plug cap and the air filter.
B:
With the mower on a solid surface, patch of gravel or similar…..
follow the points above, but in step 3 above REMOVE the bolt (taking care
not to lose the red washer). Allow the petrol to drain completely from the tank
before replacing the nut. Refill the tank with fresh unleaded fuel, and replace
the spark plug cap and air filter.
We advise the engine should be drained of fuel before storage for more
than 30 days. One should only buy fuel in quantities that can be used
Page 18 of 36

within a few weeks, and petrol should be bought from the garage and
transported/stored in approved plastic petrol containers.
NB: Where a fuel supply blockage has occurred, a service dealer
should be consulted to free the blockage.

Faulty spark plug or faulty spark plug connection:
Check the H.T. lead (spark plug cap) is
correctly fitted to the spark plug and the metal
cap inside the H.T. lead cap is pointing
forwards to make a good connection with the
spark plug. To test for a spark see 2-6 below.
Stand the machine on a firm surface and set
the height adjusters to the lowest setting for
added safety.
Remove the H.T. lead (1 in the diagram).
Unscrew the spark plug (2 in the diagram)
with a genuine spark plug spanner.
Fit the plug back into the end of the H.T. lead
(making sure the metal cap inside the rubber
cap connects closely) and rest it against the
engine block (NB hold only the black
insulation lead).
The second person can now hold in the
Operators Presence Control and pull the
engine cord. You should see a spark jump
across the end of the plug.
Oil on the spark plug will prevent any spark. To
clean oil from the spark plug, remove and clean
the spark plug completely. ONLY USE A
GENUINE SPARKPLUG SPANNER.
NOTE: If there is no spark, change the
plug. If there is still no spark refer to a
service dealer because the coil may be
faulty.

D:
Micro switch not engaging:
1. Hold the OPC bar gently in to the main
handle and listen for a faint click coming
from the back right hand corner of the
engine. You are checking here for a
micro-switch engaging which allows the
electrical feed to the spark plug. If there is
no audible click it may be that the microswitch is not fully engaged.
2. In this case, follow the OPC cable down to
the back right hand corner of the engine
where the lever moves when the OPC is
depressed. Come BACKWARDS along
the bare metal cable (2) some 8cms to
where the metal bracket (5) grips the
black plastic cable covering (directly
below the fuel filler).
3. Release the plastic cable cover by
compressing the 2 lugs (X) inwards on the
plastic cable cover that are splayed out
and hold it in place. Feed the black
plastic cable cover BACKWARDS through
the bracket (5).
X
4. With a pair of pliers bend the metal
bracket (5) BACKWARDS 4 mm towards
the handle, and then replace the cable in
the bracket. This will now engage the
micro-switch by pulling it further, and you
should now be able to start the mower in
the normal way.
E:
Faulty coil:
If the coil is faulty there will be no spark. This is a job to be carried out by
your local service dealer.

8 Pull Cord Not Pulling or Snatching Back
QUICK TROUBLESHOOTING GUIDE:
Problem:
Likely Cause:
Pull cord will not • OPC not engaged
pull
• Grass caught between
the blade and the deck
• “Hydraulic lock”
Cord snatches
back
•
•
Solution:
• Hold OPC in (see A)
• Remove grass from the
blade (see B)
• Remove oil from cylinder
(see C)
Blade rotation is impeded •
Blade is unbalanced or
•
damaged
Free blade (See D)
(See E) and refer to dealer
A:
The OPC lever must be held fully in to the main handle before the pull cord
can be pulled and the engine can run. If the OPC lever is fully engaged and
the cord will only pull out 4” or so, see C below.
B:
Remove the grassbox. Now remove the HT lead (spark plug cap) for safety
reasons, then lift the front wheels until the handles reach the ground at the
rear. Free any grass caught between the blade and the deck. Stand the
mower back on the ground on all four wheels, replace the cap on the
sparkplug and start in the normal way.
C:
Hydraulic Lock occurs if the mower has been tilted forwards and oil settles
between the piston and cylinder head, sticking the piston to the cylinder roof.
Remove and clean the spark plug completely. ONLY USE A GENUINE
SPARKPLUG SPANNER. Do not replace the plug yet.
If the cord will not pull free, tilt the mower BACKWARDS, reach underneath
and turn the blade (in either direction) to free it. Clear any grass blockage.
With the sparkplug removed, prime the engine 6 times with the primer
button, hold in the OPC lever and pull the engine over with the pull cord 6
times to eject any oil from the spark plug hole.
Replace the plug and start the engine in the normal way. The engine might
smoke quite badly at first, but allow the engine to continue running for at
least ten minutes. The smoke will begin to dissipate. Let the mower run
until the smoke has gone.
NB During subsequent uses (for maybe a further 8-10 hours) the mower may
smoke a little. Droplets of oil may come from the exhaust onto the deck as
the oil is cleared from the cylinder. Simply wipe these away with a cloth.
For best practice, only to tip your mower BACKWARDS.

RV40, V35
D:
The engine pull cord may snatch back when pulled if the machine is not on a
flat and firm surface, or the blade and/or its mounting boss are damaged or
fitted insecurely.
.
1. Ensure the machine is situated on a firm level surface (path, patio or
short grass). Check the underside of the machine is clear from old
lawn debris. If you have to tilt the mower, do this backwards only. First
remove the grass catcher, remove the HT lead (spark plug cap), then
lift the front wheels until the handles reach the ground at the rear.
2. If attempting to start the mower on the lawn, the grass beneath the
cutter can slow its rotation, and even prevent the free rotation of the
cutter, causing a “snatch back”. If the engine is cold, select a firm
surface for starting the mower. If the engine is warm, always pull the
mower back onto a pre-mown area where the grass is already short to
prevent unnecessary jamming.
E:
To check the blade, pull the cap off the sparkplug (for safety) and
remove the grass catcher from the rear of the mower. Tilt the mower
BACKWARDS so that the handle touches the ground.
.
1.
The cutter bar is retained by a central bolt.
This should be tight (the thread is the normal
anti-clockwise turn to tighten).
2.
To either side of the central bolt there are two
silver lugs protruding through the cutter bar.
If these are missing, it indicates that the
machine has come into contact with more
than normal grass and has damaged the
cutter mount (boss). This will have to be
replaced. This type of repair would not
normally be covered by warranty. It is wise to
mark the blade before removing it so that the
blade can be replaced the correct way up.

MOWER WILL NOT CUT GRASS PROPERLY
When cutting grass make
sure you are using the
machine on full throttle (if
one is fitted). If collecting
the grass ensure the
mulching plug (if
available) has been
removed.
Do not cut wet grass.
Especially in the Spring when the grass may be long
and lush, do not attempt to cut too much grass at any
one time.
If the lawn is several inches in length then raise the
height of cut and gradually reduce the lawn in stages
to prevent blocking. It may also help to remove the
grass catcher, cut the grass first on the highest setting,
and work down to lower settings and collecting the
grass.
If the grass is damp you can attempt to cut the lawn by
raising the height of cut to allow a greater airflow, and
reducing the lawn to the desired level in stages.
Check the height adjuster levers settings are the same on each wheel and that they
are at a level suitable for the grass conditions.
Mulching Mowers: (PLEASE NOTE, ALSO SEE www.mulching.co.uk for mulching
tips and how to mow better with mulching mowers)
The same advice above applies to mulching mowers. These are mowers
that are not designed to collect grass – they recycle the grass clippings,
and return natural nutrients to your lawn. NOTE: Combination mowers
use a mulching plug so they can then be used also as a mulching mower.
Follow these simple steps for the best mulching results, and remember
that to obtain the perfect cutting height you need to work down from the
Page 23 of 36
Mountfield150cc Selfhelp Guide 2011, Issue 1.0
Engine Model: RV150 and SV150
RV40, V35
maximum height setting in steps until you reach your ideal height.
1. Remember the one third rule – never remove more than one third of the
length of the blade of grass whenever you mow. This is good advice no
matter what type of mower you use!
2. Cut a little:
•
•
•
Set the mowing height to about 1½ to 2 inches for most lawns, this will
develop deeper root growth and crowd out weeds
The one third rule also implies that you should mow your grass before it
is 3” high because a mulching cutter deck will have no problem chopping
one inch of clippings into tiny particles and concealing them in the
remaining standing grass
Leaving grass to reach 5-6” high would make it impossible for any
mower to hide 3-4” of chopped clippings in just 2” of lawn.
3. Cut often:
•
Remove only one third of the grass length at each mowing. Try to mow
weekly, especially in spring – cutting too much at once stresses the
grass. Every two weeks will probably be often enough in the summer
Leave grass about half an inch longer than you would normally if you were
discharging or collecting the clippings.
Keep your mower blades sharp. Mulching tends to dull blades faster than other
methods of mowing. Sharpen them more often, if necessary.
Water the lawn after mulching, not before. Dry clippings disperse more easily than
moist ones. Watering after the lawn has been mulched helps clippings settle better
and speeds up decomposition.
B
Problems With The Blade Or Blade Mounting
Before checking the
blade, REMOVE the H.T.
lead (sparkplug cap) and
ONLY TIP THE MOWER
BACKWARDS.
Excessive vibration can
Page 24 of 36
Mountfield150cc Selfhelp Guide 2011, Issue 1.0
Engine Model: RV150 and SV150
RV40, V35
indicate damage to the
blade, or blade
mounting, or that the
engine is loose
Check the blade bolt is tight.
WARNING: Mark the blade before attempting to
remove it. This will enable you to replace it the
correct way up.
Check the blade mount. The mount has two lugs
one either side of the blade securing bolt. If these
have sheered then the blade can move.
If the blade mount has failed, a replacement can
be purchased through your local Mountfield
dealer.
Loosening the blade
(it is a normal thread, so
turn anti-clockwise to
remove the blade)
The Blade mount is only likely to fail because
the blade has come into contact with an
obstruction of some form. The blade mount is
designed to fail in order to protect the engine
crankshaft.
Check the condition of the cutter blade - if badly
worn or damaged, replace with a new one. If a
new cutter blade has been fitted, check that it has
been installed the correct way up (the wing tips at
either end should bend upward into the mower
chassis and not downward towards the ground).
Check that all 3 bolts securing the engine are in
place and tight.

C
Build-Up of Grass Clippings Underneath or Lack of
Airflow
When cutting
grass make sure
you are using the
machine on full
throttle (if one is
fitted).
Raising the height
of cut increases
airflow and
assists grass
collection. This is
especially so if
the grass is damp.
Reducing the
height of cut in
stages to achieve
the desired level
is a sound
strategy.
1. Ensure there is no build up of grass underneath the
casing. Before checking the underside, make
sure to remove the HT Cap (sparkplug cap).
2. Only access the under side of the machine by
removing the grass catcher then lifting the machine
from the front until the handles touch the ground at
the rear).
3. Check the grass catcher allows air to pass through
it. If heavily soiled, wash it in warm soapy water to
clear old deposits of grass juices and debris. A
good airflow is essential for efficient grass
collection.
4. If grass is very long, remove the grass catcher, and
work with the deflector plate (stone guard) in
position. Clippings can be collected after a few
hours drying by simply going over the lawn again
with the grass catcher fitted, and the wheels set
slightly higher.
5. Should the machine become blocked with grass
when using it, stop the mower and remove the
H.T. lead (spark plug cap). Remove the grass box,
insert your hand through the rear aperture and
clean away any build up of grass clippings. DO
NOT TIP THE MOWER FORWARDS, OR
SIDEWAYS, OR UPSIDE DOWN.
6. Walk around to the front of the mower and raise the
front wheels in the air until the handles reach the
ground at the rear. Clean away any grass clippings
which have accumulated on the underside.
7. Once cleaned, lower the machine, re-fit the H.T.
lead (spark plug cap) and restart the engine.

please contact the Helpline service on 0845 600 2912 (Monday to
Saturday 9am – 5pm, and Sunday 10am – 4pm).
A ADJUSTING THE TENSION ON THE CLUTCH CABLE
FOR MOWERS WITH THE CLUTCH ON THE
RIGHT HAND SIDE OF THE HANDLE:
a) Check the clutch cable runs up the right hand side
of the main handle (right hand side viewed from
behind the mower) and through the tension
bracket (shown as 1 in the diagram above). If the
cable is not in this bracket, insert it and follow the
instructions in b) below to adjust the tension.
b) Check the tensioning bracket (shown as 1 in the
diagram above) because this can have moved up
the handle or the cable may have stretched a little
with use. Slacken the screw in the bracket,
slide the bracket DOWN the handle to take up
spare slack in the cable, and tighten the
screw. NOTE: The cable should have about
½” of play on it.
c) If the above steps do not return the tension to
the cable and restore the drive, the cause of
Page 27 of 36
Mountfield150cc Selfhelp Guide 2011, Issue 1.0
Engine Model: RV150 and SV150
RV40, V35
the problem may be the belt has come off the
drive pulleys (see Section 2) or the clutch
cable has broken or become detached (see a
service dealer).
FOR MOWERS WITH THE CLUTCH BAR RUNNING
ACROSS THE HANDLE:
a) Check the clutch cable runs up the left hand
side of the main handle through the anchoring
bracket on the handle. If the cable is not in
this bracket, insert it and secure the bracket to
the handle, then follow the instructions in b)
below to adjust the tension.
b) The cable may have stretched a little with use.
Slacken the bottom nut on the adjusting
barrel and then tighten the top nut on the
adjusting barrel to take up un-required
slack in the cable. NOTE: The cable
should have about ½” of play on it.
c) If the above steps do not return the
tension to the cable and restore the drive,
the cause of the problem may be the belt
has come off the drive pulleys (see
Section B) or the clutch cable has broken
or become detached (see a service
dealer).
B REPLACING THE BELT
Find your local
ServiceLink centre at
www.servicelink.org.uk
To replace the belt on these machines, it will
involve tipping the machine to gain access to the
belt. You will need to observe certain general and
safety precautions prior to undertaking this task.
Chose an appropriate firm surface to work on such
as a workbench - not standing on a high quality
patio or lawn (these could be stained or damaged
by machine fluids).
WARNING: Make sure you have disconnected the
HT lead from the spark plug (it is a simple push fit)
Page 28 of 36
Mountfield150cc Selfhelp Guide 2011, Issue 1.0
Engine Model: RV150 and SV150
RV40, V35
before you undertake ANY of the work below.
The air filter cover and filter element/sponge
will need also to be removed. This is located
on the right hand side of the engine, secured
with a single clip to the rear of the cover. Push
this in and the cover will release.
Now follow the sequence of steps below:
1. Remove the grassbox
2. Check you have already removed the spark
plug cap (for safety reasons) and the air filter
(to avoid potential contamination)
3. Without tipping the mower forwards or
sideways, lift the mower up onto a workbench
on all 4 wheels, and position the back wheels
close to the edge of the workbench
4. Raise the stone guard flap, tip the mower
BACKWARDS with the handle hanging over
the edge of the bench – it will stand upright
like this
5. Mark the blade so that after removing it you
can replace it the correct way
6. Unscrew the blade (normal thread so turn the
spanner anti-clockwise to unfasten)
7. Remove the belt guard plate – this is the
protective plate through which the blade shaft
protrudes……it is between the blade and the
deck of the mower (it may be held on by a
single screw, 2 screws and a nut, or 4
screws)
8. If the belt is broken, a replacement must be
purchased from the service dealer. Position
the belt around the pulley on the blade shaft
Find your local
9. On the back axle there is a black/grey box
ServiceLink centre at
(the transmission unit) and on the uppermost www.servicelink.org.uk
face of this is a pulley – wind the belt onto this
Page 29 of 36
Mountfield150cc Selfhelp Guide 2011, Issue 1.0
Engine Model: RV150 and SV150
RV40, V35
pulley as if winding a chain onto a bicycle
wheel (it may appear that this pulley is at an
angle, but the tension of the belt will
straighten this)
10. Replace the belt guard plate and re-attach the
blade the correct way up
11. Carefully lift the mower down onto the ground
without tipping it forwards or sideways and
replace the spark plug cap and air filter.
NOTE: If the belt repeatedly comes
adrift, this is normally a sign that either
grass is finding its way into the belt
compartment, or the belt is worn or
damaged and should be replaced.
Whenever ordering spare parts
ALWAYS quote the model number of
your machine to the dealer.

11 Transportation and Handling
The correct way to gain access underneath the mower:
Before checking the underside, make sure to
remove the HT Cap (sparkplug cap).
ALWAYS lift from the front of the mower so that
the front wheels are raised, and the handles touch
the ground at the rear. Do not tip the mower
sideways or forward (like one might lift a
wheelbarrow) as this can flood the air filter,
exhaust and even the cylinder with engine fluids.
It may be helpful to place a weight on the handle to
maintain the mower in this position when working
beneath the deck.
Whenever the machine is to be handled, raised onto a workbench or
transported, remove the HT Cap (sparkplug cap):
1. Wearing strong gloves and taking account of the weight and its distribution,
grasp the machine at the points that offer a safe grip.
2. Use an appropriate number of people for the weight of the machine and the
characteristics of the vehicle or the place where it has to be placed or
collected.
3. When lifting the machine to and from a vehicle or onto a workbench, take
care to keep it level. DO NOT TIP IT.
4. The handles may be folded to ease storage and transportation. It is
important to take care not to trap the operating cables when collapsing
the handles.

12 Maintenance and Storage
Regular and careful maintenance is essential to preserve original performance
and safety levels of the engine. Always store the mower in a dry place. Please
also refer to the Engine Routine Maintenance information for additional help.
Key maintenance and storage information (all engines):
1. Keep all nuts, bolts and screws tight to ensure the equipment is in safe
working condition. Regular routine maintenance is essential for safety and
performance.
2. Never store the mower with fuel in the tank inside a building where vapour
may reach a flame or a spark or a source of extreme heat.
3. Allow the engine to cool before storing in an enclosed space.
4. To reduce the fire hazard, keep the engine, exhaust silencer, battery
compartment (if fitted) and fuel storage area free of grass, leaves, or
excessive grease. Do not leave containers of grass cuttings in rooms.
5. Check the stone guard and grass collector frequently for wear and
deterioration.
6. If the fuel tank has to be drained, this should be done outside and when the
engine is cool.
7. Wear strong work gloves while removing or assembling the blade.
8. Keep the blade balanced during sharpening. All operations on the blade
(dismantling, sharpening, balancing, remounting and/or replacing) require a
certain familiarity and (in some cases) special tools. For safety reasons these
tasks are best carried out by one of our authorised service dealers.
9. For safety reasons, DO NOT use the equipment with worn or damaged
parts. Parts are to be replaced and not repaired. Use genuine spare parts
only. Parts that are not of the same quality can damage the equipment and
be dangerous for your safety.
If the lawnmower is to be stored for more than 30 days (e.g. over the winter
period), drain the fuel from the tank or allow the engine to run until it runs out
of fuel. This should always be done outdoors. To empty the fuel from the
engine, see section 4 Starting the engine, sub-section A.
Alternatively, because this engine has a gravity feed, the engine can be allowed to
run until it runs out of petrol.
