10. Storage
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.
ANGLE TRANSMISSION
• The reduction gears are lubricated by multipurpose,
lithium-based grease in the angle transmission. Sup-
ply new grease every 25 hours of use or more often
depending on the job condition.
• Remove the bolt of the grease nipple and the bolt
opposite side of the grease nipple. Install new grease
into the grease nipple to arrange for old grease to
exit from the opposite side.

FLEXIBLE SHAFT

ward.

hole, apply Zenoah Guine Power Grease (Z3180-

the shaft, and insert the shaft back into the liner.
3. Replace the inside seal at the grip side of the flexible

INTAKE AIR COOLING VENT
WARNING
• Check the intake air cooling vent after every 25
hours of use for blockage, and remove any waste
which has attached itself to the brushcutter.
IMPORTANT
• If waste gets stuck and causes blockage around the
intake air cooling vent, it may cause the engine to over-
heat, and that in turn may cause mechanical failure
on the part of the brushcutter.
