blades before use and after refueling. Check the cutters for damage or incorrect
adjustment.
Check for loose or missing screws or components.

are tight.
WARNING!
Before performing any maintenance, repair, or cleaning work on the
unit, make sure the engine and cutting attachment are completely stopped.
Disconnect the spark plug wire before performing service or maintenance work.
WARNING!
Non-standard parts may not operate properly with your unit and may
cause damages and lead to personal injury.

Lubricate the cutter assembly gearbox by pumping one or two strokes of
lithium-base grease into the grease fitting using a lever-type grease gun. See
Fig.HT13
CAUTION!
Over-lubricating can cause the gear case to operate sluggishly and
can cause grease to leak out.

Every 50 hours of operation (more frequently in dusty or dirty conditions):
1.
Remove and clean the cylinder cover and clean the dirt and debris from the
cylinder cooling fins.
