Cutting performance of your machine

depends a great deal on proper cutter

blade adjustment. Properly adjusted

blades will oscillate 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

rmly, and then loosen the shoulder

bolts 1/4 to 1/2 turn.

3. Working from the gearcase end, lock

each bolt in place by rmly 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 (0.010 - 0.020 in.)

between the cutter blades and the at

washers, and the at washer beneath

each bolt head should turn freely.

WARNING!

The cutter blades are very sharp!

Always wear gloves when working

around the cutter assembly.

CAUTION!

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.
