CHAPTER 5
MAINTAINING THE DR POWER GRADER
This chapter covers regular maintenance procedures that will ensure the best performance and long life of
your DR POWER GRADER.
WHEN PERFORMING ANY MAINTENANCE, YOU MUST FIRST SHUT OFF THE TOW VEHICLE, SET THE
PARKING BRAKE AND UNPLUG THE CONTROL CABLE. READ THE "GENERAL SAFETY RULES" (CHAPTER 2)
OF THIS MANUAL BEFORE PERFORMING ANY REPAIRS OR MAINTENANCE.
Regular Maintenance Check:
• Keep the battery charged. See page 17.
• Hose down the DR POWER GRADER to keep the Scarifying Teeth Plates clean and clear of debris.
DO NOT USE A POWER WASHER; THIS MAY FORCE WATER THROUGH THE SEALS ON THE HEIGHT
ADJUSTING ACTUATOR.
• Verify that all Nuts and Bolts are tight.
• Check the Shear-Bolt for wear by grabbing the end and try to wiggle it. Replace the Shear-Bolt if
worn or loose. Do not over tighten.
• Lubricate the Caster Wheel bearings every 25 hours of operation. See page 30.
• Check the general condition of the DR POWER GRADER, e.g., nuts, bolts, welds, etc.
• Periodically, (every 50 hours is recommended) remove the Scarifying Teeth Plates and clean
between the plates and frame. This will allow for proper securing of the Scarifying Teeth Plates in
their set position.
