Helpful Operating Hints
The following hints will help protect against a plugged
discharge chute, plugged rotor housing, sheared
driveline bolt, and help keep the chipper running.
• Be careful not to feed too much product at once, feed
oversize product, feed wet product, or feed product too
fast. Doing so can plug the Wood Chipper.
• Alternate leafy material with a non leafy hardwood
piece. Hard wood pieces help clean out leafy material.
Keep alternating leafy material with hardwood pieces
until leafy material is processed.
• Let leafy branches dry for a couple weeks before
chipping them. Dry leaves will process better.
• Maintaining 1/32" gap between ledger bar and knives
will keep knives wiped off, prevent plugging, allow
product to feed better, and keep wood chipping.
Plugged Chutes & Rotor
Refer to Figure 4-6:
Clear plugged chutes and rotor as follows:
1. Place gear selector in park, set park brakes,
disengage PTO, shut tractor engine off, remove
switch key, and wait for all moving parts to come to a
complete stop before working on this machine.
2. Disconnect driveline from tractor PTO shaft.
3. Unplug feed chute, discharge chute and rotor as
follows:
Unplug Feed Chute (#1)
a. Be sure to complete steps 1 & 2 above.
b. Pull all material out of feed chute. Make sure
nothing is jammed between inlet opening and
rotor at bottom of feed chute.
c. Loosen product jammed at the bottom with a stick
or board by prying it up and to the right.
d. If prying on product does not free it, then access
inlet opening by removing hex flange screws (#7),
flat washers (#8), and feed chute (#1).
e. Do not reattach feed chute (#1) until after
checking rotor for a plugged situation.
Unplug Rotor (#3)
