GENERAL OPERATION
GENERAL OPERATION
• Replace the clean-out door after all the chips are removed, be sure to use both the
lock washers and flat washers.
• Do not operate the chipper without the chip deflector in place.
• Before stopping the chipper, be sure that all of the material is out of the chipper
head and out of the in feed roller.
• All of the material in the chute must be gone or the unit could jam on a small piece
of material. This can usually be cleared by turning the unit backwards by hand.
• Dull knives cause many problems such as: seeming lack of power, plugging of
the discharge chute, rough cutting with more vibration than usual, feed roll shaft
broken, main bearing house broken, main bearing working loose and the flywheel
or knives hitting the case or bed knife, feed roller kicking out of gear, and not
feeding.
• When sharpening the knives, be careful to keep angle A at a 37-39° angle. Knives
cannot be rounded, or the knives will not pull the material into the head.
(See
Flywheel Knife Sharpening Instructions
on page 30)
• The best way to tell if the knives need sharpening is to watch the chips coming out
of the chip discharge. If they are long and straight, the knives are in need of service.
Sometimes the knives feel sharp to the fingers, but may be worn or rounded. They
will need to be sharpened.
• When operating the Wood Chipper, make sure you are standing in the safe
OPERATOR ZONE. You must stay in the safe operating area at all times when the
chipper drum is in motion. Never place any part of your body into a position that
causes an unsafe operating condition.
