Cutter Blade Adjustment

Figure 29

Cutter performance of your machine

depends in great measure on cutter blade

clearance. Properly adjusted blades will

oscillate freely yet help prevent binding of

cut material between blades. Adjust blades

as follows (Figure 26):

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 shoul-

der 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.

CAUTION!

Over lubricating can cause the gear-

box to operate sluggishly and can

cause grease to leak out.
