9. Maintenance

INTAKE AIR COOLING VENT

WARNING

•  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 doing so could result in severe 

burns.

•  When checking the machine to make sure that it 

is okay before using it, check the area around the 
muffler  and  remove  any  wood  chips  or  leaves 
which  have  attached  themselves  to  the 
brushcutter. Failing to do so could cause the muf-
fler to become overheated and that in turn could 
cause  the  engine  to  catch  on  fire.  Always  make 
sure  that  the  muffler  is  clean  and  free  of  wood 
chips, leaves, and other waste before use.

•  Check  the  intake  air  cooling  vent  and  the  area 

around  the  cylinder  cooling  fins  after  every  25 
hours of use for blockage, and remove any waste 
which has attached itself to the brushcutter. Note 
that it is necessary to remove the upper cover and 
the lower cover shown in in order to be able to 
view the upper part of the cylinder.

IMPORTANT

•  If waste gets stuck and causes blockage around the 

intake air cooling vent or between the cylinder fins, 
it may cause the engine to overheat, and that in turn 
may  cause  mechanical  failure  on  the  part  of  the 
brushcutter.

cooling vent

PROCEDURES TO BE PERFORMED AFTER

EVERY 100 HOURS OF USE

1.  Remove the muffler, insert a screwdriver into the vent, 

and wipe away any carbon buildup. Wipe away any 
carbon buildup on the muffler exhaust vent and cylin-
der exhaust port at the same time.

2.  Tighten all screws, bolts, and fittings.
3.  Check to see if any oil or grease has worked its way 

in between the clutch lining and drum, and if it has, 
wipe it away using oil-free, lead-free gasoline.

Aged fuel is one of major causes of engine starting fail-
ure. Before storing the unit, empty the fuel tank and run 
the engine until it uses all the fuel left in the fuel line and 
the  carburetor.  Store  the  unit  indoor  taking  necessary 
measures for rust prevention.
