Safety Instructions-Cont.
• A well-prepared traffic plan includes parking off the highway whenever
possible. Cone the work area 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. Ensure chips or dust do not blow into traffic, parked
cars, or pedestrians.
• Check the bolts on the following for correct torque (75 ft. lbs.) every 10 hours
of operation:
1. Chipper rotor bearing
2. Chipper blades (use 5/16” bolts (20 ft. lbs.))
3. Rotor blades
4. Chipper anvil
For hydraulic feed models:
5. Hydraulic feed roller bearing
6. Hydraulic motor mounting
Failure to maintain proper fastening torque (75 ft. lbs.) on component bolts listed
above may result in severe damage to the chipper and/or personal injury.
• Shut off engine and allow machine to stop completely before clearing debris if
the machine becomes clogged.
• On electric start models, disconnect cables from battery before doing any
inspection or service.
• Rotate the discharge tube to face the opposite direction of the towing
vehicle before towing. This prevents the discharge tube from projecting
over the trailer wheels and striking foreign objects.
• Lock the rotor by inserting a bolt or punch through the locking holes on
the side of the rotor housing.
