OP1.
5.4. Move the choke lever (1) to the closed position (2). OP2.
5.5. Set the ignition switch (4) to the start position (5). While
pulling the throttle lever (7), push the throttle set button and
release the throttle. The throttle is now in the start positon.
(OP3).
Page 10
5.6. Whilst holding the unit firmly, quickly pull out the recoil
starter handle until the engine fires. OP4.
5.6.1. Avoid pulling the recoil starter handle/rope to its full
extent or allow it to return by letting go of the handle.
Such actions can cause starter failure.
5.7. Move the choke lever (1) downward (3) to open the choke,
and restart the engine. OP2.
5.8. Allow the engine to warm up before starting work.
When restarting the engine immediately after stopping it, leave the choke open.
Over-choking can make the engine hard to start due to excess fuel.
When the engine fails to start after several attempts, open the choke and
repeat the starter handle pulling or remove the spark plug and dry the plug of
excess fuel.
5.9. Stopping the engine.
5.9.1. Release the throttle lever (7) and run the engine for at least ½ a minute.
5.9.2. Then move the ignition switch to the stop position (6). OP3
5.10.

the carburetor side end. Readjust with the cable
adjuster as required. (OP5).
5.11.
Adjusting the idle speed.
5.11.1. If the machine tends to stop frequently at idling
mode, turn the adjusting screw clockwise.
5.11.2. When the cutting head keeps rotating after
releasing the throttle trigger, turn the adjusting
screw anti-clockwise.
You must make adjustments after the engine has had time to warm up.
5.12.
Cutting (trimming) with cord.
Always wear eye protection, such as safety goggles. Never lean over
the rotating cutting head. Stones and other debris can be thrown
from the cutting head, these may be thrown towards the eyes, head
and body causing injury.
Always keep the guard in place whilst the machine is being used.
Page 11
5.12.1. Trimming grass and weeds.
5.12.1.1. Remember that it is the tip of the cord
that’s does the cutting. You will achieve best
results by not trying to overcut instead allow
the unit to trim at its own pace.
5.12.1.2. Hold the unit so the head is of the ground
and is tilted about 20° toward the sweep
direction. OP7.
5.12.1.3. You can help avoid debris and stones form
being thrown by cutting form your left to your right.
5.12.1.4. Use a slow and deliberate action to cut heavy growth. The rate of
cutting motion will depend on how much is being cut. Heavy growth will
require slower action than lighter growth.
5.12.1.5. Never swing the unit so hard as you might be in danger of losing your
balance or loss of machine control.
5.12.1.6. Try to control the cutting motion with the hip rather than placing the
full workload on the arms and hands.
5.12.1.7. Always take precautions to avoid wires, grass and dead dry long
stemmed weeds from wrapping around the shaft. If this happens it can
stall the machine and cause clutch slip which if repeated can cause
damage to the clutch.
5.12.2. Adjusting the cord length.
5.12.2.1. Your brush cutter is equipped with a semi-auto type nylon cord head
that allows the operator to advance the cord without stopping the engine.
When line cord becomes too short lightly tap the head on the ground
while running the engine at full throttle.
5.12.2.2. Each time the head is bumped the cord will advance about 25mm. For
better effect tap the head on bare ground or hard soil. Avoid bumping in
thick tall grass as the engine may stall by overloading.

MAINTENANCE
You must make sure that the engine has stopped, allowed to cool down
and disabled before commencing any maintenance work.
6.1. Refilling trimmer cord.
6.1.1. Use a replacement cord of 2.4 mm, the spool is capable of taking a cord
length of 6m on the standard head. Avoid using larger line as this will cut down
on the performance of the trimmer.
For safety reasons DO NOT use metal reinforced cord.
6.1.2. (1) - Pinch the slotted area on both
sides of the spool housing to unlock the
bottom cap.
6.1.3. (2) – Take the spool out and remove
the old cord. Fold a new piece of cord (3)
so the one half of the line is 120mm
shorter that the other half. Then hook the
bent over end into the slot on the spool.
6.1.4. (4) Wind up the line in the correct
direction as indicated on the spool.
6.1.5. (5) Hook each end of the cored in the
slots on the edge of the spool. Then pass
the cord ends through the eyelets (6) on
the housing.
6.1.6. (7) While holding the spool against the
housing pull the cord ends to release
them from the slots.
6.1.7. (8) Line up the slot on the bottom cap
with the hook on the housing, press the
cap against the housing until it clicks
securely.
6.2. Air filter.
6.2.1. If the air filter becomes clogged it will
reduce the engines performance.
6.2.1.1. Check and clean the air filter
element (1).
6.2.1.1.1. Wash in warm soapy water,
rinse in clean water. Allow
the filter to dry before reinserting into machine. N.B. if
the filter is damage replace it
with a new one.
Page 13
6.3. Fuel filter.
6.3.1. If the engine does not run smoothly check
the fuel filter (1), clean and/or replace as
required. To clean filter remove and wash in
clean fuel.
6.4. Spark plug.
6.4.1. Starting failures and mis-fires are
often caused by a fouled or incorrectly
gapped spark plug.
6.4.2. Remove the HT lead and undo the
spark plug in an anti-clockwise
direction.
6.4.3. Clean and/or replace spark plug.
To re-insert spark plug tighten up
gently by hand to avoid cross threading, once done tighten it using a box
spanner ¼ turn more. Make sure the spark plug is tightened correctly
otherwise damage can occur.
6.4.4. NOTE The use of any spark plug other than the one designated may result
in the engine failing to run correctly becoming overheated and damaged.
6.5. Exhaust muffler.
Inspect periodically for any loose
fasteners, damage or corrosion. If any
signs of exhaust leakage are found STOP
using the machine and get it properly
repaired or replaced. NOTE failure to get
the exhaust repaired or replaced may
result in the engine catching fire.
6.5.1. The exhaust muffler is fitted with a spark
arrester (1).
6.5.1.1. The spark arrester is fitted to help
prevent red hot carbon from exiting the
exhaust.
6.5.1.2. You must check and clean it with a wire brush. NOTE You must make
sure that the exhaust has been given time to cool down.
6.6. Gear case.
Page 14
6.6.1. The reductions gears are internally lubricated
by using a multipurpose lithium based grease .
6.6.2. The grease should be topped up every 25 hours
– more often if required.
6.6.3. To fill with grease remove the side bolt opposite
the grease nipple to allow for excess grease to
come out of the gear case.
6.6.4. DO NOT overfill with grease.
6.7. Intake air cooling vent.
Never touch the cylinder, muffler or spark plugs with your bare hands
immediately after stopping the engine. The engine can become very
HOT when in operation, and in doing so could result in severe burns.
When checking the machine make sure that it is okay before using it,
check the area around the exhaust muffler and remove any flammable
materials which may have attached to the machine. Failure to do so
could cause the exhaust muffler to becomes overheated, and this in turn
could cause the engine to catch on fire.
Always make sure that the exhaust muffler is clean and free of word
chips, leaves and other flammable waste before use.
6.7.1. Check the intake air cooling vent and the area
around the cylinder cooling fins every 25 hours for
signs of blockages. Remove any waste and blockages.
NOTE it may be necessary to remove the engine cover
to view the upper part of the cylinder (1).
6.7.2. IMPORTANT If waste gets stuck and causes a
blockage around the intake air cooling vent or
between cylinder fins, it may cause the engine to
overheat, and in turn may cause mechanical failure.
6.7.3. Procedure to check exhaust muffler must be
carried out after every 100 hours of use.
6.7.3.1. Remove the exhaust muffler, insert a
screwdriver into the vent and wipe away any
carbon build up. At the same time wipe away
any carbon build up on exhaust muffler
exhaust vent and cylinder ports.
