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. Shut tractor down properly before dismounting. Refer
to
2. Disconnect driveline from the tractor.
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)
a. Be sure to complete steps 1 & 2 on this page.
b. Remove hex flange screw (#6).
c. Rotate upper rotor housing (#4) up until locking
strap (#5) supports the housing.
d. Clean rotor housing of debris.
e. Manually rotate rotor to make sure all debris is
removed and rotor is not jammed.
f. Rotate rotor housing (#4) down and secure with
existing 3/8"-16 hex flange serrated screw (#6).
Tighten serrated screw to the correct torque.
Unplug Discharge Chute (#2)
a. Be sure to complete steps 1 & 2 on this page.
b. Make certain discharge chute (#2) is clean. Pull
material out of the discharge chute. If necessary,
use a stick to unplug a jam.
4. Reattach feed chute (#1) with existing 5/16"-18 x 3/4"
GR5 hex flange screws (#7) and flat washers (#8).
Tighten hex flange screws to the correct torque. See
on page 16 for detailed installation
instructions of feed chute.
5. Reattach driveline to tractor power take-off shaft.
