AIR CLEANER
Check the filter element and clean it in warm, soapy water as
required. Dry completely before installing. If the element is
broken or shrunk, replace with a new one.
(1) Air Cleaner element.
A clogged air filter will increase fuel consumption and cut
down the engine power.
If you operate the brushcutter without the air filter or
with a deformed filter element it will quickly ruin the
engine.
FUEL FILTER
Take the filter out of the fuel tank using a small wire hook.
Disconnect the filter assembly from the fuel pipe and unhook the
retainer to disassemble it. Clean the components with petrol.
A clogged fuel filter will reduce the power of the engine.
SPARK PLUG
Remove and inspect the spark plug and clean the electrodes
as necessary with wire brush.
The spark gap should be adjusted to 0.6~0.7mm.
If a new spark plug is fitted it must be the same type as the original
one.

COOLING AIR INTAKE VENT
•
Check the cooling air intake vent and the area around the
cylinder cooling fins, and remove any waste which has
attached itself to the brushcutter.
•
Failing to keep the air path clear could cause the muffler
to become overheated, and this in turn could cause the
brushcutter to catch on fire.
GEAR CASE
(BC 260 S2 and BC 325 S2 only)
•
Remove the screw from the side of the gearbox.
•
Remove the cutter and the inner
flange to allow old grease to exit.
•
Using a grease gun, supply multi-
purpose grease after every 25
hours of use.
AFTER 100 HOURS USE
MUFFLER
1. Remove the muffler, insert a screwdriver into the vent, and
scrape away any carbon buildup. Scrape away any carbon
build-up on the muffler exhaust vent at the same time.
2. Tighten all screws, bolts, and fittings.
3. Undo the four socket screws holding the engine to the housing
at the top of the main tube and check to see if any oil or grease
has worked its way in between the clutch lining and drum If it
has, wipe it away using oil-free, lead-free petrol.
ADJUSTING THE CARBURETTOR
A wrong adjustment may cause damage to your unit. If the
engine does not run well after adjusting the carburettor,
please contact your service agent.
Adjustments & service are not covered by warranty.
IDLE ADJUSTMENT SCREW
(All models)
The horizontal screw (1) contacting the side of the butterfly lever
arm on top of the carburettor adjusts the idling speed. If you turn
right (clockwise), idle speed increases, and left (counterclockwise) it
decreases. Adjust the speed if the blade continues to rotate when
the engine is idling (not applicable to the BC 230B S2 model), or if
the engine stops when you release the throttle lever.
1. Idle adjustment screw
2. Choke lever
3. Throttle cable
MAINTENANCE BEFORE STORAGE
1. Clean the machine down thoroughly and inspect for any wear
or damage. If you find any, have it corrected so the machine will
be ready for use next time.
2. Empty the fuel from the tank. If the engine will start, run it until it
stops from lack of fuel.
3. Remove the spark plug and put in 1~2 drops of 2-cycle oil in
the engine. Pull the starter rope 2~3 times and then replace the
spark plug.
4. Apply anti-rust oil to the metal parts such as the throttle wire,
put the cover on the blade, and store it indoors, avoiding
dampness.
