Concrete drilling and doweling are tough on equipment, but following these general guidelines will help keep your drills running at peak performance through thick and thin.

Check the oil once per day depending on workload and model and refill with rock drill oil if necessary. Proper lubrication is critical to the drill’s operation.

Trunnion Bolts
Ensure the trunnion bolts are not cracked or broken.

Loose Parts
Constant repetitive vibration from the drill can cause bolts and parts to loosen. Tighten them securely on a regular basis.

Wear Parts
Check the pawl, pawl springs and air tubes for wear that occurs over time. Replace them when necessary.

Any time the drill will be out of service for an extended period of time, you need to  prepare it for storage to prevent rusting of the internal components.

  • Pour a small amount of rock drill oil directly into the motor and run the drill at half throttle to lubricate all of the parts.
  • Drain any condensation from the filters.
  • Cover the unit with a tarp if it will be stored outdoors.

Do these basic checks before running your drill after it has been stored.

  • Ensure there is adequate oil.
  • Make sure all bolts are tightened.
  • Check for appropriate tire pressure.
  • Blow out the hose that runs between the compressor and drill to ensure it’s clean.
