Cutter blade (Fig. 4-1, 2)
The blades are installed to the cutter guide with three to five bolts depending on cutter length. Those bolts are
tightened with a clearance so that the cutters can move smoothly.
When clearance is too small:
The cutters do not move properly and the sliding surfaces may seize.
When clearance is too large:
The cutters are poor in sharpness.
To adjust the cutter clearance:
1. Loosen the cutter fixing nuts.
2. Fully tighten the cutter fixing bolts and then loosen them approx. 1/2 turn.
3. With the bolts set at that position, tighten the cutler fixing nuts.
Be sure to replace cutter guide fixing bolts when they are loosened, worn or damaged. Also be sure to replace
damaged cutter blade.
NOTE!
Properly lubricate the cutler sliding surfaces with machine oil.
Gear case (Fig. 4-3)
Apply a good quality lithium based grease through the grease fittings.
As to some models, one of the grease fittings has been moved from
upper location (4) to the bottom (5).
NOTE!
Lubrication should be applied at 50 hour intervals and more
frequent at heavy use.
