Recommended Service Schedule
We recommend doing the first preventative maintenance at about 30 service hours. Following this service,
select maintenance tasks should be performed monthly, every six months, and so forth. Please refer
to Index B: Service Checklist for a comprehensive list of preventative maintenance tasks and when to
complete them.
Replacement Parts
Use only manufacturer-recommended replacement parts. Other parts may be substandard in fit and
quality.
For additional replacement parts, contact the service provider (Index A).
Maintenance Precautions
Always take proper safety precautions while servicing this equipment. For complete RB4000 safety
and operation guidelines, refer to the Operator’s Manual. If you do not have a manual, contact the
manufacturer’s recommended service provider.
Always perform maintenance when the vehicle is level.
Never do any maintenance or adjustments while the equipment is operating. Turn off the engine when
performing maintenance to prevent accidental movement.
Never perform maintenance on this machine unless the dump box is completely in the transport position
(fully retracted and lowered). To perform maintenance under the dump box, the box can be tilted in the
dump position. It must be secured with the support arm in place. Never perform maintenance with the
dump box in the lifted position.
Make sure all operating and residual pressures are relieved before working on a hydraulic system.
Shut engine off and operate all the controls to relieve any pressure.
Replace all safety shields and guards when finished performing maintenance. Do not operate the
equipment with protective equipment removed.

until it’s tight.
INSPECT PARKING BRAKE
• Pull out the breakaway pin and listen for the actuator to make a humming noise from behind the
engine area.

a 30-amp fuse (not included in this 6-month service kit).
INSPECT BREAKAWAY SYSTEM
• Visually inspect to ensure there’s no dry rot, wear, or damage that exposes the wires beneath.
• Damaged hoses should be replaced immediately by a qualified service shop.
CHECK HYDRAULIC HOSES
TIRES
• Front tires: visually inspect, check
pressure, and, if needed, tighten lug nuts.
• Rear tires: visually inspect and check
pressure. You must also make sure rear
tire lug nuts are tightened to 140 ft-lbs,
in the order outlined in the illustration.

NOTE: Never work under the raised dump
box without using the safety arm to prevent
the box from falling down.
All four stabilizers and rollback must be
fully extended when greasing fittings on the
RB4000.
Greasing guidelines vary slightly on pre-
2014 RB4000 units. For older units, contact
the manufacturer’s recommended service
provider (Index A) for guidance on grease
locations.
Use provided grease tube to apply lubricant
to the following areas on all units:
LUBRICATE FITTINGS
Slide Rails

grease to slide rails directly.
1. With the rollback fully extended, grease
the 3” x 5” tubes.
2. Grease the inside of the 4” x 6” tubes.
Wheel Lock Pin

fitting is accessible.
For additional replacement parts or service assistance, contact the maufacturer’s recommended service
provider.
