Maintenance and care
Gearcase lubrication
Lubricate the cutter assembly gearbox by pumping one or two
strokes of lithium-base grease into the grease fitting using a le-
ver-type grease gun.
Over lubricating can cause the gearcase to operate
sluggishly and can cause grease to leak out.
Cylinder cooling fins
Remove and clean the cylinder cover and clean dirt and debris
from the cylinder cooling fins.
Remove and replace the fuel filter
Use a piece of metal wire or the like to pick up fuel filter
through fuel tank opening.
Pull old filter from fuel line.
Install new fuel filter.
NOTE
If filter is excessive dirty or no longer fits properly, replace it.
Gearcase lubrication
To perform this operation, first remove the gearcase from the out-
er tube as follows:
1. Loosen the gearcase clamp bolt.
2. Remove the index bolt from the gearcase.
Do not remove the D-shaped shim washer from the
gearcase clamp. The shim washer prevents damage
from overtightening the tube clamp bolt.
