REGULAR MAINTENANCE
AIR FILTER
The air filter should be cleaned each time the brushcutter is used. (Or more often with extreme conditions.)
Remove the filter cover and take out the element. Wash the element in kerosene or warm detergent, then
squeeze it dry. Apply oil (#30 wt.) to foam, removing all excess oil. Assemble and reinstall the element and
filter cover.

SPARK PLUG
The spark plug should be removed from the engine and
checked after each 25 hours of operation. The tips can be
cleaned with a stiff brush.
Adjust the gap to 0.6-0.7mm (see sketch). Replace the spark
plug if it is oil fouled or damaged, the average spark plug life
is approximately 100 hours.
CAUTION-Do not over tighten the spark plug. The correct
torque is 10.7-16.6N • m(100 -160 kgf • cm).
