Maintenance
Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away from all
openings. Always stop engine, disconnect the spark plug wire, and make sure all moving parts have come to a com-
plete stop before removing obstructions, clearing debris, or servicing unit. Allow unit to cool before performing service.
Wear gloves to protect hands from sharp edges and hot surfaces.
Daily Maintenance
Prior to each work day, perform the following:
Clean any debris or dirt from the cutting attachment.
Lubricate the cutters before use and after refueling. Check the cutters for damage or incorrect adjustment.
Check for loose or missing screws or components. Make sure the cutting attachment is securely fastened.
Make sure nuts, bolts, and screws are tight.

Gearcase lubrication
Remove the shaft bolt, bolt guard, holder A, blade, holder B, and
the output shaft collar. Press new grease into the gearcase until
the old grease has been pushed out. Use only lithium-base
grease.
Lubricate the flexible shaft
Lack of lubrication will cause rapid wear to the flexible shaft and
also to the shaft tube liner, resulting in increased vibration and
greatly decreased service life. Remove and lubricate the flexible
shaft as follows:
1.
With the unit on a clean, flat surface, loosen the coupler
screw knob. The spring-loaded Latch protector should pop
up.
2.
Press down on the latch with your finger or thumb. This re-
leases the coupler lock.
3.
Pull the tool assembly out of the coupler.
4.
Pull the flexible shaft and bushing from the shaft tube as-
sembly.
NOTE
For extended shaft life, the flexible cable should be reversed
end-for-end during the reinstallation process.
