5 - 6 times, then move the throttle lever to the choke / start or run position and pull the
starter cord as above.
Starting the lawnmower - hot starts:
Follow the above #1 to #5 steps for restarting after emptying catcher or short rest periods. A
warm engine will usually start in the idle position. However, if it fails to start, follow the cold start
Stopping the engine:
To stop the engine, move the throttle control to the stop position. Turn the fuel shut-off valve
(where fitted) to the close / off position when the mower is not in operation to prevent fuel
leakage from the carburettor.
Throttle control lever:
The throttle control lever is located
on the right hand handle for the
530SPB models.
The throttle lever is moved fully
forward into the detented choke /
start position to start a cold engine.

away from the cutting mechanism and danger zones. To start simply pull the zone start handle
firmly as you push the mower handlebar away.
Recoil start handle:
Refer to the engine manufacturer’s owners’ handbook for details.
Cutting height adjustment:
The single lever height adjustment makes for easy change from one height setting to another.
There are ten height of cut settings available (from 10 mm to 65 mm) and the most suitable
height should be selected that best suits the grass and weather conditions. To adjust the height
of cut setting, follow the steps below.
 Grip the height adjust lever by the black knob.
 Apply an outward force to the lever to disengage it from the quadrant rack setting.
 Holding the lever out, move the lever up
or down the quadrant rack to the desired
height of cut.
 Engage the lever into the quadrant rack
by releasing the outward force.
Note that when using a mulching lawnmower,
using the higher height settings will give the
best mulching performance.
There are two holes in the axle bell cranks on
the left hand side of the mower. The correct
setting for the connecting rod link is to have
the rear of the link in the top hole and the front
of the link in the lower hole.

power consumption and prolonged life for the cutting edges. Carry out the following procedures
before commencing work and re-check the settings every 2 to 3 hours of mowing or when the
cutting performance is noticeably reduced. During mowing, the blade tips can move relative to
the mower body through normal work or by hitting obstructions. Check that the cutting blade(s)
is correctly set to the mower body by measuring the distance the blades are inside the
lawnmower skirt, this distance should nominally be 3 mm. Disconnect the spark plug cable and
carefully rotate the blade by hand and check that the distance is nominally correct all around the
mower body. If adjustment is necessary, proceed as follows
Remove the spark plug cable from the spark plug.
Rotate the blade(s) until it is accessible from the rear flap area.
Re-fit the spark plug cable.
If it is impossible to obtain a good clean cut, it may be necessary to take the mower to your local
Service Agent to have a new set of blades fitted.
Grass catcher:

the grass catcher or raising the rear flap.
Note that if the lawnmower is used with the
catcher removed, the rear flap must be fitted and located in the down / closed position. To fit the
grass catcher, stop the engine and position the catcher on the ground behind the mower. Raise
the rear flap and lift the catcher into position ensuring the catcher tongue is located over the
rear axle. Slide the catcher forward and upward; lower the flap so that the lugs on the flap locate
into the square holes on top of the catcher. Your catcher is now attached.
To remove
the grass catcher, stop the engine, hold the catcher by its top handle raise the rear flap. Lift the
grass catcher up and away from the lawnmower and return the grass flap to its down / closed
Avoid leaving the catcher in direct sunlight when not in use. The catcher will not deteriorate if
stored wet but prolonged exposure to sunlight can cause premature UV breakdown. Dust and
clippings will build up inside the catcher and on its venting screen, particularly during wet
weather mowing. This debris will impede the function of the catcher so it should be removed by
hosing out with water when necessary.

Clean the air cleaner:
Remove and clean the air filter cartridge at three monthly intervals or every 25 hours of normal
use. The air filter cartridge may require servicing more often under dusty or commercial
operating conditions. To service the air cleaner cartridge, follow the procedures detailed in the
engine manual.
Check spark plug:
Clean and reset the spark plug gap every 25 hours of operation. Remember, in small engines,
difficult starting and erratic running is most often
attributable to a dirty, oily or carbonated spark plug.
Do not file or sand blast the spark plug electrode but
clean by scraping or wire brushing, then cleaning with
a commercial solvent. Clean and reset the spark plug
gap at 0.7 - 0.8mm (0.030”) every 100 hours of
Always fit the recommended spark plug.
Rotating screen:
Through prolonged operation, the rotating screen may become clogged with grass and debris.
Clean the screen in line with the engine manufacturers recommendations to avoid over heating
and possible engine damage.
Throttle control & Self Propelled control:
Lubricate the cable every 25 hours of mowing by applying a light oil to the top of the inner wire
and allowing it to gravity drain down the inside. The throttle control lever quadrant should have
medium grease smeared over it to protect it from corrosion and to give a smooth operation.
Fasteners and linkages:
Check that all nuts, bolts, pins and linkages are secured correctly in place and are in good
Blade Care:
Check the condition of the blades, bolts and cutter assembly regularly. Remember that badly
worn blades will affect grass cutting, catcher fill and cause excessive mower vibration.
Change Worn or Damaged Blades:
It is recommended that you use an authorised Service Agent for any replacement or balancing
blade work. Always fit a complete set of blades and fasteners to maintain balance

Carburettor Adjustment:
Check your engine Manufacturers Maintenance Instructions when carburettor adjustment is
required to compensate for changes in fuel, temperature, altitude or load.
Cleaning the Mower Body:
There is a direct relationship between the lawnmower’s life and the care and attention given to
the lawnmower both during and after operation. After use it is important that the lawnmower is
thoroughly cleaned down and inspected so that it will be in good working order the next time it is
required. Disconnect the spark plug lead and thoroughly clean the engine, underside of the
chassis, wheels and grass catcher.
CAUTION Do not use a water hose around
the engine as this may contaminate the fuel or
enter the ignition system and result in poor
engine performance and starting problems.
Your rotary lawnmower features a wash nozzle
for easy cleaning of the underside of the body.
Simply run the lawnmower at a moderate speed,
place a garden hose into the wash nozzle and
turn on the water supply for two to three minutes.
The action of the rotating blade system will
dislodge most grass and debris build up.
Cleaning the Catcher:
Simply hose out the catcher and screen after each use to ensure maximum mower performance
and catcher fill.
CAUTION Care should be used when
cleaning around the muffler, ensure that the
muffler is cool enough to touch before cleaning.
Always clean around the muffler area regularly to reduce the risk of fire and damaging the
mower. Brush the grass, dirt or combustible debris from the muffler.
Cleaning under self propelled drive cover:
The area under the drive assembly guard should be cleaned out on a regular basis.
 The drive assembly cover should be removed and the area cleaned out of any debris.
 Under normal use we recommend doing this once per month.
After each mowing season or if the lawnmower is not going to be used for 30 days or more, it is
recommended that
1. The engine oil should be changed.
2. All fuel should be removed.
Run the engine until it is warm and drain the engine oil and refill with the correct grade to the
required level.
The fuel shut off valve should be closed off (where fitted) then remove all fuel from the
carburettor, fuel line and tank to prevent the formation of gum like deposits The lawnmower
should then be started up and run until all of the fuel left in the system is used.
Remove the spark plug and pour 15 cc of engine oil into the cylinder, crank slowly to distribute
the oil and replace the spark plug. Store the lawnmower in a clean dry area away from direct
sunlight, as this will have an aging effect on the plastic catcher assembly and other plastic
