DANGER: This machine was built to be operated according to the rules for safe operation in this
manual. As with any type of power equipment, carelessness or error on the part of the operator can
result in serious injury. This machine is capable of amputating hands and feet and throwing objects.
Safe
Operation Failure to observe the following safety instructions could result in serious injury or death.
Training
Preparation
1. Read, understand, and follow all instructions on the ma-
chine and in the manual(s) before attempting to assemble
and operate. Keep this manual in a safe place for future
and regular reference and for ordering replacement parts.
2. Be familiar with all controls and their proper operation.
Know how to stop the machine and disengage them
quickly.
1. Thoroughly inspect the area where the equipment is to
be used. Remove all rocks, bottles, cans, or other foreign
objects which could be picked up or thrown and cause
personal injury or damage to the machine.
2. Always wear safety glasses or safety goggles during opera-
tion or while performing an adjustment or repair, to protect
eyes. Thrown objects which ricochet can cause serious
injury to the eyes.
Practices
3. Never allow children under 16 years old to operate this
machine. Children 16 years old and over should read and
understand the operation instructions and safety rules in
this manual and should be trained and supervised by a
parent.
3. Wear sturdy, rough-soled work shoes and close-fitting
slacks and shirts. Loose fitting clothes or jewelry can be
caught in movable parts. Never operate this machine
in bare feet or sandals. Wear leather work gloves when
feeding material in the chipper chute.
WARNING
4. Never allow adults to operate this machine without proper
instruction.
4. Before starting, check all bolts and screws for proper tight-
ness to be sure the machine is in safe working condition.
Also, visually inspect machine for any damage at frequent
intervals.

Maintenance & Storage
1. Do not put hands and feet near rotating parts or in the
feeding chambers and discharge opening. Contact with the
rotating impeller can amputate fingers, hands, and feet.
2. Before starting the machine, make sure the chipper chute,
feed intake, and cutting chamber are empty and free of all
debris.
1. Never tamper with safety devices. Check their proper
operation regularly.
2. Check bolts and screws for proper tightness at frequent
intervals to keep the machine in safe working condition.
Also, visually inspect machine for any damage and repair,
if needed.
