secured. Once every 10 hours of operation, all
screws, nuts, bolts, and other fasteners should be
checked for proper tightness to insure everything is
in proper working condition.
Operation
One of the critical moments in job safety, as well as
chipper safety, is setting up your chipping site so you are
not endangered by traffic and the public is not
endangered by your work. Great care must be taken to
provide adequate warning by way of signage and coning,
if it is necessary to divert vehicle or pedestrian traffic.
A well-prepared traffic plan should include parking off
the highway whenever possible. The work area should
be coned off as soon as the chipper vehicle is stopped.
Avoid sudden traffic stoppage or lane diversion. Do not
allow pedestrians to walk through the work area. Make
sure chips or dust do not blow into traffic, parked cars,
or pedestrians.
1. Before starting the machine, make certain that the
cutting chamber is empty.
2. When feeding chipable material into the machine, be
extremely careful to exclude pieces of metal, rocks,
bottles, cans, and other foreign objects.
3. If the cutting mechanism strikes any foreign object
or if the machine should start making an unusual
noise or vibration, immediately shut off the engine,
and allow the machine to come to a complete stop.
After machine stops:
a) Inspect for damage.
b) Replace or repair any damaged parts.
c) Check for and tighten any loose parts.
4. Every 10 hours of operation, check the bolts on the
following for correct torque (75 ft. lbs.):
• Hydraulic feed roller bearing
• Hydraulic motor mounting
• Chipper rotor bearing
• Chipper blades
• Rotor paddles
• Chipper anvil

This chipper is designed and tested to offer
reasonably safe service. However, failure to
operate it in accordance with the following safety
instructions MAY RESULT IN PERSONAL IN-
JURY!
Before Operating
1. Become familiar with the owners manual before
attempting to operate this equipment. See engine
owners manual for additional safety information.
2. Do not allow children to operate this equipment.
3. Do not operate this equipment in the vicinity of
bystanders.
4. Carbon monoxide can be extremely dangerous in
enclosed areas; do not run the machine in an
enclosed area. The exhaust from the engine con-
tains carbon monoxide, which is colorless, odorless,
and tasteless.
5. Do not allow hands, or any part of body or clothing,
inside the feeding chamber, discharge chute, or near
any moving part.
6. Before inspecting or servicing any part of the
machine, shut off the engine, and make sure all
moving parts have come to a complete stop.
Preparation
1. Obtain and wear safety glasses at all times while
operating the machine. One pair of safety glasses is
provided with each chipper.
2. Avoid wearing loose-fitting clothing. Never operate
this machine wearing loose clothing particularly if it
has drawstrings which could wrap around or get
caught in the machine.
3. Operate the machine only on a level surface. Do
not operate the machine on a paved, concrete, or
hard gravel surface. Operating on a hard surface
may cause discharged material to rebound and
kickback. It will also cause increased machine
vibration. Increased vibration may cause the ma-
chine to move and will promote premature wear of
parts or loosening of fasteners.
4. Before starting the machine, visually check that all
screws, nuts, bolts, and other fasteners are properly
