Provide a good air supply.

1. REDUCE OR ELIMINATE CONDENSATION (MOISTURE) FROM THE AIR SUPPLY

  • Use water traps and drains
  • Use refrigerated air dryer

2. PREVENT DEBRIS FROM ENTERING THE AIR MOTOR

  • Filter the air
  • Keep the air inlet connections, plugs and couplers clean, free of dust and debris
  • Keep exhaust mufflers and elements in place. Muffler elements provide a barrier that will prevent dust from being pulled into the air motor
  • Do not use compressed air to blow-off the tool; this could force debris into bearings

3. LUBRICATE THE AIR MOTOR

  • Use an automatic lubricator to supply the correct weight and amount of air motor oil
  • Supply the air motor oil manually, directly into the air inlet. Apply 2-3 drops throughout the day
