• Check the fuel filter periodically. Do not allow dust to
enter the fuel tank. A clogged filter will cause difficulty
when starting the engine or abnormalities in engine
performance.
• When the filter is dirty,
replace the filter.
• When the inside of the fuel tank is dirty, it can be cleaned by
rinsing the tank out with petrol.
Checking the spark plug
Check the spark plug every 10-15 hours of use.
1. Remove the spark plug cover.
2. Use the spark plug spanner (20) to remove the spark
plug, by turning it anti-clockwise (Fig. a).
3. Clean and adjust the spark
plug gap to 0.6 - 0.7mm.
Replace any damaged or
visibly worn plug with a NGK
BPMR7A or CHAMPION
CJ7Y spark plug, as listed in the specification table.
4. Install the spark plug finger tight in the cylinder head, then
tighten it firmly with the spark plug spanner (Fig. b).
Servicing
• It is recommended once you first use your petrol brush
cutter to get it serviced after 15 hours of use.
• From thereafter, service the petrol brush cutter every
2 years.
Storage and maintenance after use
• When you finish working, clean the petrol brush cutter
completely, making sure there is no grass or dirt
wrapped in the cutting tools, replace the blade cover
and put it back into its package in order to avoid its
hurting you or other people during transport.
• Be aware to not hit or cut the fuel tank if you put it onto
the ground. Do not let the petrol brush cutter fall down
to the floor or it may damage the machine.
• Store the petrol brush cutter away from direct sunlight.
• Do not store in a nylon bag as this can encourage the
formation of mould.
• At the end of the season, give the petrol brush cutter an
overall cleaning and a thorough check.
• Do not leave the petrol brush cutter resting on the floor
for extended periods as it could cause the shape of the
guard to alter, posing a safety risk. Hang it off the floor
by the top handgrip.
Whenever the machine is not used for a long period of
time, proceed as follows:
• Empty the fuel tank completely.
• Protect all metal engine parts from corrosion by coating
them with oil.
• Remove the spark plug, put a few drops of oil into
the cylinder and then pull the recoil starter 2 to 3
times in order to distribute the oil evenly. Replace
the spark plug.
