Cleaning the air filter
N Loosen filter cover mounting 
screws.
N Remove the filter cover.
N Clean away loose dirt from around 
the filter (5) and inside the filter 
cover.
N Knock the filter (5) out on the palm 
of your hand or blow it clear with 
compressed air from the inside 
outwards.
In case of stubborn dirt or sticky filter 
fabric:
N Wash the filter in a clean, non-
flammable solution (e.g. warm 
soapy water) and then dry.
Always replace a damaged filter.
If engine is down on power, difficult to 
start or runs poorly at idling speed, first 
check the spark plug.
Fit a new spark plug after approx. 100 
operating hours or earlier if the 
electrodes are badly eroded.
Wrong fuel mix (too much engine oil in 
the gasoline), a dirty air filter and 
unfavorable running conditions (mostly 
at part throttle etc.) affect the condition 
of the spark plug. These factors cause 
deposits to form on the insulator nose 
which may result in trouble in operation.
Removing the Spark Plug

until the screw head projects from it.
N Lift the front of the cap (2) and push 
it to the rear to disengage.
N Leave the cap to one side.
N Pull off the spark plug boot (3).
N Unscrew the spark plug.
