Adjusting cutter blades

Cutting performance of your machine 

depends a great deal on proper cutter 

blade adjustment. Properly adjusted 

blades will oscillate freely yet help pre-

vent binding of cut material between 

blades. Adjust blades as follows:

Loosen all blade locknuts at least 

1. 

one full turn.
Tighten each blade shoulder bolt 

2. 

firmly, and then loosen the shoulder 

bolts 1/4 to 1/2 turn.

Cutter blade adjustment

Working from the gearcase end, 

3. 

lock each bolt in place by firmly 

tightening its locknut while prevent-

ing the shoulder bolt from turning.

When shoulder bolt adjustment is cor-

rect, 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.

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.
