The product is equipped with a centrifugal clutch mechanism, so the cutting
attachment begins to rotate as soon as the engine is started by putting the
throttle into the start position. When starting the engine, place the product
onto the ground in a flat clear area, and hold it firmly in place so as to ensure
that neither the cutting part nor the throttle come into contact with any
obstacle when the engine starts.
After starting the engine, check to make sure that the cutting attachment
stops rotating when the throttle is moved fully back to its original position.
If it continues to rotate even after the throttle has been moved fully back,
turn off the engine and take the unit to your authorized servicing dealer for
repair.
Important: Remove any obstacles before beginning work.
Important: Never place the throttle into the high-speed position
when starting the engine.

The engine is designed to run on a mixed fuel, which contains highly
flammable petrol.
Never smoke while operating the unit or refilling its fuel tank.
When refilling the tank, always turn off the engine and allow it to cool down.
Safety
Never store cans of fuel or refill the fuel tank of the unit in any place where
there is a boiler, stove, wood fire, electrical sparks, welding sparks, or any
other source of heat or fire which might ignite the fuel.
Ensure that there are no sparks or open flames anywhere nearby before
refuelling.
Wipe spilled fuel up completely using a dry rag if any fuel spillage occurs
during refuelling.

Multi Tool FM5-1
13
If Someone Comes
Safety
Guard against hazardous situations at all times. Warn adults to keep pets
and children away from the area. Be careful if you are approached. Injury
may result from flying debris.
If someone calls out or otherwise interrupts you while working, always be
sure to turn off the engine before turning around.
Brush Cutter Kickback
12h
2h
Attention Rebound
An uncontrolled kickback of the blade may occur when
using the brush cutter.
This kickback phenomenon occurs in particular when performing cuts in the
critical angle of the blade, i.e. the angle between 12 and 2 o’clock.
Never use the trimmer with the blade angle between 12 and 2 o’clock.
Never use such a blade angle for cutting solid materials such as bushes,
roots etc whose diameter is greater than 3cm. The trimmer could be violently
projected to the side and may cause injury.
This uncontrolled kickback of the blade is more likely to occur when the
user cannot see the material being cut.
This uncontrolled kickback can cause serious injury or even death, to the
user or other people or animals. Always keep people and animals at least
15m away from the machine.
Warning: Never use the trimmer with the blade angle between 12
and 2 o’clock.
14
Multi Tool FM5-1
Chainsaw Kickback
Tip contact in some cases may cause a lightning fast reverse
reaction, kicking the guide bar up and back towards the operator.
Pinching the saw chain along the top of the guide bar may push the
guide bar rapidly back towards the operator.
Safety
Kickback may occur when the nose or tip of the guide bar touches
an object, or when the wood closes in and pinches the saw chain in
the cut.
Either of these reactions may cause you to Iose control of the saw,
which could result in serious personal injury.
Do not rely exclusively on the safety devices built into your saw. As
a chain saw user you should take several steps to keep cutting jobs
free from accident or injury, such as:
Steady, methodical work
Proper revision of this manual
Good diligence
A clear visual of your work area
With a basic understanding of kickback you can reduce or eliminate
the element of surprise. Sudden surprise contributes to accidents.
Keep a good grip on the saw with both hands, the right hand on the
rear handle, and the left hand on the front handle, when the engine
is running. Use a firm grip with thumbs and fingers encircling the
chain saw handles. A firm grip will help you reduce kickback and
maintain control of the saw.
Make certain that the area in which you are cutting is free from
obstructions. Do not let the nose of the guide bar contact a log,
branch, or any other obstruction which could be hit while you are
operating the saw.
Cut at high engine speeds.
Do not overreach or cut above shoulder height.
Follow the manufacturer’s sharpening and maintenance
instructions for the saw chain. Only use replacement bars and
chains specified by us at Forest Master.
Multi Tool FM5-1
15
Make sure the chain and sprocket are correctly adjusted before operating
the pruner. Never attempt chain adjustment with the engine running!
Safety
Always make sure the cutting attachment is properly installed and firmly
tightened before operation.
Never use a cracked or warped guide bar: replace it with a serviceable one
and make sure it fits properly.
If a saw blade should bind fast in a cut, shut off the engine immediately.
Push the branch or tree to ease the bind and free the blade.
Do not operate the pole pruner with the exhaust removed.
When cutting a limb that is under tension, be alert for springback so that
you will not be struck by the moving limb.
Always stop the engine immediately and check for damage if you strike
a foreign object or if the machine becomes tangled. Do not operate with
broken or damaged equipment.
Important: Do not make unauthorised
substitutions to the guide bar or chain.
modifications
or
Never allow the engine to run at high RPM without a load. Doing so
could damage the engine.
Keep the pruner as clean as possible.

Multi Tool FM5-1
The vibration during use of the power tool can differ depending on the ways
in which the tool is used. There is the need to identify safety measures to
protect the operator that are based on an estimation of exposure in the
actual conditions of use (taking account of all parts of the operating cycle
such as the times when the tool is switched off and when it is running idle
in addition to the trigger time).
Prolonged used of a tool (or other machines) may expose the operator to
vibrations that may product white finger disease (Raynaud’s syndrome) or
carpal tunnel syndrome.
Safety
Vibration
These conditions reduce the hand’s ability to feel and regulate temperature,
produce numbness and may cause nerve and circulation damage and tissue
necrosis.
To help in the prevention and reducing the risk of the white finger disease,
please note the following:
wear gloves and keep your hands warm;
maintain a firm grip at all times, but do not squeeze the handles with
constant pressure,
take frequent pauses
Even when the tool is used as prescribed it is not possible to eliminate all
residual risk factors. The following hazards may arise in connection with the
tool’s construction and design:
a. Damage to lungs if an effective dust mask is not worn.
b. Damage to hearing if effective hearing protection is not worn.
c. Health defects resulting from vibration if the tool is being used
over longer period of time or not adequately managed and properly
maintained.
Wear hearing protection while operating the tool.
Always Wear The Provided Harness When Using The Machine
Always make sure the machine is hooked securely to the harness. If you
don’t, you will be unable to control the machine safely. This can result in
injury to yourself or others. Never use a harness with a defective quick
release or any other damage.
Multi Tool FM5-1
17
Safety
Note: careful daily inspection should be performed before use and after a
drop or shock to identify major defects. Do not use the machine until the
defects have been repaired.
Restrict working hours to a minimum and always take rest periods. For
proper use, after each work period take a rest period (for example take a
rest for 10 minutes after a work period of 30 minutes).
When you finish cutting in one location and wish to continue work in another
spot, turn off the engine, lift up the unit and carry it paying attention to the
blade. Never forget to place the protective cover over the blades.
When hand-carrying the product, cover over the cutting part if necessary, lift
up the product and carry it paying attention to the blade.

Petrol is highly flammable. Avoid smoking or bringing any flame
or sparks near fuel. Make sure to stop the engine and allow it
cool before refuelling the unit. Select outdoor bare ground for
fuelling and move at least 3 m (10 ft) away from the fuelling
point before starting the engine.
The engine is specially designed for air-cooled two stroke mixed fuel use.
Use only 2-stroke oil that is suitable for air cooled engines. Do not use BIA or
TCW (2-stroke water-cooled marine type) 2-stroke oil.
Operation
Filling With Oil And Fuel
How To Mix Fuel
Recommended mixing ratios;
Petrol 40 / Synthetic Oil 1

2.
3.
4.
Measure out the required quantities of petrol and oil to be mixed.
Put some of the petrol into a clean, approved fuel container.
Pour in all of the oil and agitate well.
Pour in the rest of petrol and agitate again for at least one minute.
As some oils may be difficult to agitate depending on oil ingredients,
sufficient agitation is necessary for engine protection. If the agitation is
insufficient, there is an increased danger of early piston seizing due to
abnormally lean mixture.
5. Put a clear indication on the outside of the container to avoid mixing up
with petrol or other containers.
6. Indicate the contents on outside of container for easy identification.
Fuelling The Unit
1. Untwist and remove the fuel cap. Rest the cap on a dustless place.
2. Put fuel into the fuel tank to 80% of the full capacity.
3. Fasten the fuel cap securely and wipe up any fuel spillage around the
unit.
Warning: Select bare ground for refuelling.
Move at least 10 ft (3 metres) away from the fuelling point before
starting the engine.
Stop the engine before refuelling. At that time, be sure to
sufficiently agitate the mixed fuel in the container.

When restarting the engine immediately after stopping it,leave the choke
open.
Overchoking can make the engine hard to start due to excess fuel. If the
engine fails to start after several attempts, open the choke and repeat pulling
the rope, or remove the spark plug and dry it.
Adjusting The Throttle Cable
The normal play is 1 or 2 mm when measured at
the carburettor side end. Readjust with the cable
adjuster as required.
Adjusting Idle Speed
Warm up the engine before adjusting the idling
speed.
1. If the engine stops frequently at idling mode,
turn the adjusting screw clockwise.
2. When the cutting head keeps rotating after
releasing the trigger, turn the adjusting screw
counter-clockwise.
Warning: The product is equipped with a centrifugal clutch
mechanism, so the cutting attachment begins to rotate as soon as
the engine is started by putting the throttle into the start position.
When starting the engine, place the product onto the ground in
a flat clear area and hold it firmly in place, so as to ensure that
neither the cutting part nor the throttle come into contact with any
obstacle when the engine starts.

Operation
Operation Of The Brush Cutter And Trimmer
Choose the blade or choose a suitable recommended cutting attachment,
according to the object to be cut.
Working With The Edge Trimmer (With The Nylon Line)
1. Always wear eye protection such as safety goggles. Never lean over the
rotating cutting head. Rocks or other debris could be thrown into eyes and
face and cause serious personal injury.
2. Keep the cutting attachment guard in place at all times while the unit is
operated.
Trimming Grass And Weeds
1. Hold the unit so the head is off the ground and is tilted
about 20 degrees toward the sweep direction.
2. You can avoid thrown debris by sweeping from your
left to the right.
3. Use a slow, deliberate action to cut heavy growth. The
rate of cutting motion will depend on the material being
cut. Heavy growth will require slower action than with
light growth.
4. Never swing the unit hard as you are in danger of losing
your balance or control of the unit. Try to control the
cutting motion with the hip rather than placing the full
work load on the arm and hands.
28
Multi Tool FM5-1
Adjusting The Line Length
Your brush cutter is equipped with a semi-auto type nylon line head, that
allows the operator to advance the line without stopping the engine. When
the line becomes short, lightly tap the head on the ground while running
the engine at full throttle.
Operation
5. Take precautions to avoid wire, grass and dead, dry, long stem weeds
from wrapping around the head shaft. Such materials can stall the head
and cause the clutch to slip, resulting in damage to the clutch system
if repeated frequently.
Each time the head is bumped, the line advances about 1 inch (25.4 mm).
For better effect, tap the head on bare ground or hard soil.
Working With The Brush Cutter (With The Metal Blade)
1. Use the front left side cutting.
2. Guide the blade from your right to left with it tilted slightly
to your left.
3. When mowing a wide area, start working from your left end to
avoid interference of cut grass.
4. The blade may be seized by weeds if the engine speed is too
low, or the blade cuts too deep into weeds. Adjust the engine
speed and cutting depth according to the condition of object.
5. If grass or other objects are caught in the blade, or if the unit
starts to shake or vibrate, turn off the engine and check the
whole unit. Change the blade if it has been damaged. Turn off
the engine and make sure the blade has completely stopped
before checking the blade, and removing any objects that are
trapped.
Important: Make sure to use the harness and cutting attachment
guard.
Multi Tool FM5-1
29
Operation
Securing Bolt Safety Check
1. Before each use, check the bolt that fastens the blade and be sure the
bolt is secure and has no fault, and no abrasion.
2. Be sure that the blade and the holder have been fastened securely and
that the blade turns smoothly without abnormal noise.
3. Rotating parts fastened incorrectly may cause serious accident to the
operator.
4. Make sure that the blade is not bent, warped,cracked, broken or damaged.
5. If you find any fault or damage to the blade, discard it and replace with
a new one.
Controlling Blade Thrust
Blade thrust can cause serious personal injury. Carefully study this section.
It is important that you understand what causes blade thrust, how you can
reduce the chance of blade thrust and how you can remain in control of the
unit if blade thrust does occur.
What causes blade thrust:
Blade thrust can occur when the moving blade contacts an object that it
cannot cut. This contact causes the blade to stop for an instant and then
suddenly move or “bounce” away from the object that was hit. The operator
can lose control of the unit and the blade can cause serious personal injury
to the operator or any person nearby if the blade contacts any part of the
body.
How you can reduce the chance of blade thrust:
a. Recognize that blade thrust can happen. By understanding and
knowing about bounce, you can help eliminate the element of surprise.
b. Cut fibrous weeds and grass only. Do not let the blade contact
materials it cannot cut such as hard, woody vines and bushes or rocks,
fences, metal, etc.
c. Be extra prepared for bounce if you must cut where you cannot see
the blade making contact such as in areas of dense growth.
d. Keep the blade sharp. A dull blade increases the chance of bounce.
Important: Check the blade securing bolt before each use.
30
Multi Tool FM5-1
How you can maintain the best control:
a. Keep a good, firm grip on the unit with both hands. A firm grip
can help neutralize bounce. Keep your right and left hands completely
around the respective handles.
b. Keep both feet spread apart in a comfortable stance and yet braced
for the possibility that the unit could bounce. Do not over reach. Keep
firm footing and balance.
Operation
e. Avoid feeding the blade too rapidly. The blade can bounce away from
material being cut if the blade is fed faster than its cutting capability.
f. Cut only from your right to your left.
g. Keep your path of advance clear of material that has been cut and
other debris.
Maintenance Of Blade
Check the blade and the fasteners for looseness, cracking, or bending.
1. Keep the end corner sharp.
2. Round the root of the edge, using a round file.
3. Do not use water when using a grinder.
It is recommended that filing should be done by professionals.
Transporting The Unit
When you finish cutting in one location and wish to continue work in another
spot, turn off the engine, lift up the unit and carry it, paying attention to the
blade.
Never forget to place the protective cover over the blades.
When transporting the unit over long distances, detach the blade and fasten
the unit by ropes.

Working With The Hedge Trimmer
32
This product is equipped with extremely sharp blades and when used
improperly these blades can be extremely dangerous. Improper handling
can cause accidents, which may in turn lead to serious injury or death. For
this reason, you should always be careful to follow the following instructions
when using your trimmer.
• Never hold the trimmer in a way in which the blades are pointed towards
someone else.
• Never allow the blades to come into proximity with your body while the
engine of the trimmer is in operation.
• Always be sure to turn off the engine before changing the angle of the
blades, removing branches which have become stuck in the blades, or at
any other time when coming into close proximity with the blades.
• Always wear work gloves made of leather or sturdy material when using
the trimmer.
• Always place the blade cover provided with the trimmer over the blades
when not in use.
• Falling branches may fall onto the face or into the eyes, resulting in
injuries, scratches, and cuts, and for this reason you should always be
sure to wear a helmet and face protector when using your trimmer.
•
The thickness of branches, which may be cut using this trimmer, is limited
to up to approximately 3/16” (5 mm). Never try to cut branches thicker than
this, as doing so may result in damage to the trimmer.

Chain oil
Pour the chain oil into the oil tank (2) and tighten
the cap securely.
After starting the engine, run the chain at medium
speed and see if chain oil (1) has scattered off, as
shown in the figure.
The oil reservoir has a capacity sufficient to
provide about 40 minutes of cutting time (when
set to deliver the optimal flow rate, or about as
long as you’ll get from a tank of fuel). Be sure to
refill the oil tank every time when refuelling the
saw.
Warning: Never fill the pole pruner oil reservoir with the engine
running.

Oil Flow Rate
The guide bar and chain are lubricated automatically by a pump that operates
whenever the chain rotates. The pump is set at the factory to deliver an
optimal flow rate.
Locating holes
Locking pin
Locking sleeve
Adjusting the pruner head angle
The angle of the pruner head can be adjusted through 90 degrees. This
makes it easier to cut high branches as you are pulling down on the shaft
rather than pushing the shaft.
1. Pull the locking sleeve back along the shaft so that the locking pin is
clear of the locating hole.
2. Change the position of the pruner head to the desired angle.
3. Slide the locking sleeve back along the shaft to engage the locking pin in
the required locating hole.
Warning: Always wear work gloves made of leather or sturdy
material when using the polesaw.
Falling branches may fall onto the face or into the eyes, resulting
in injuries, scratches, and cuts, and for this reason you should
always be sure to wear a helmet and face protector when using
your polesaw

Brush Cutter Edge Strimmer
Maintenance
The reduction gears in the angle transmission
are lubricated by multipurpose, lithium based
grease. Supply new grease every 25 hours of
use, or more often depending on the usage
frequency of the product.
Remove the cutter holders before installing
new grease, to allow for old grease to exit.
Refilling The Trimming Line
1. For replacement line, use a line with diameter of 2.4mm (.095in). The spool
is capable to holding up to 2.5m. Avoid using a larger line as it may reduce
the trimming performance.
2. Pinch the slotted area on the both sides of the spool housing to unhook the
bottom cap.
3. Take out the spool and pull off the old line. Put one end of new line through
the spool holes and pull it until the length is equal between each part of the
line.
4. Wind up the line in the correct direction as indicated on the spool.
5. Hook each end of the line in the slot on the edge of the spool, and then put
the ends through the eyelets on the housing. Make sure that the spring and
the washers are in place.
6. While holding the spool against the housing, pull the line ends to release
them from the slot.
7. Line up the slot on the bottom cap with the hook on the housing, press the
cap against the housing until it clicks.

Blades
When refilling the tank or resting, it is often a good idea to use the time to
oil the cutting blades.
If a gap exists between the upper and lower blades, follow the procedure
below to adjust them so that they fit more closely together.
1. Loosen lock nut (A) as shown in the diagram.
2. Tighten screw (B) fully, and then turn onethird to one-half of a rotation backward.
3. While holding onto the screw to keep it in
position, tighten the lock nut.
4. Check to make sure that the flat washer (C)
is loose enough so that it may be turned by (1) Upper blade
(2) Lower blade
pressing on it with a finger.
Transmission
The reduction gears are lubricated by multipurpose, lithium based grease
in the transmission. Supply new grease every 25 hours of use or more often
depending on the job condition. When adding lubricant, use a grease gun to
insert lubricant into the three grease nipples located on the transmission.
Note: Screwing in the screw too tightly may make it impossible for
the blades to move. Conversely, not screwing in the screw tightly
enough may make the blades of the trimmer feel dull and cause
leaves and branches to become caught in the blades of the trimmer.
