3. Slide the gearcase out of the tube. Using a grease gun,
pump lithium-base grease (about 10 grams) into the grease
fitting on the gearcase until you see old grease being purged
from the gearcase. Purged grease will be visible in the outer
tube cavity.
4. Clean up excess grease, then reassemble the gearcase
onto the outer tube. Make sure the index bolt fits into the hole
on the outer tube. Securely tighten both bolts.
The cutter blades are very sharp. Always wear gloves
when working around the cutter assembly.
Failure to observe the precautions could cause an accident
or injury, or even lead to a fatality.
Cutting performance of your machine depends a great deal on
proper cutter blade adjustment. Properly adjusted blades will os-
cillate freely yet help prevent binding of cut material between
blades. Adjust blades as follows:
1. Loosen all blade locknuts at least one full turn.
2. Tighten each blade shoulder bolt firmly, and then loosen the
shoulder bolts 1/4 to 1/2 turn.
3. Working from the gearcase end, lock each bolt in place by
firmly tightening its locknut while preventing the shoulder
bolt from turning.
When shoulder bolt adjustment is correct, there should be a gap
of 0.25–0.50 mm between the cutter blades and the flat washers,
and the flat washer beneath each bolt head should turn freely.
Operating the trimmer with worn or improperly adjusted
cutters will reduce cutter performance and may also
damage your machine. Never operate the machine with
damaged or worn cutters.
Whenever the unit will not be used for 30 days or longer, use the
