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.
