Adjusting Non-Clog Knife Hold-Downs
IMPORTANT:
Overtightening the hold-downs will cause rapid wear on hold-downs and knife sections. Wear is increased if operating in sandy or muddy conditions.
NOTE:
Hold-downs are cast iron. Knife hold-down (A) keeps knife section (B) from lifting off guard (C), allowing knife to slide without binding.
1.
Position knife with one half of knife section under hold down and one half of knife section on guard ledger surface.
2.
Insert a feeler gauge between hold-down and knife section. Adjust cap screw to obtain 0.13-0.25 mm (0.005-0.010 in.) gap between hold-down and knife section.
3.
Oscillate knife by hand. Knife must be free to move.
4.
Operate machine for 3 minutes to make sure knife sections do not bind.
