PROBLEM SOLVING DRY AND WET DRILLING

- Too high speed.

- The drilling machine is left on “hammer”.

2. Diamond drill does not cut or drills too slowly

- RPM too high or too low: check speed.

8. Core is lodged within the diamond bit

MAINTENANCE

Keep the tool clean and prevent any accumulation of dust or par-

ticles that may penetrate inside the tool.

After 300 hours work, have the carbon brushes checked by a

RIDGID service station.

The brushes will need to be replaced when they become shorter

than 5 mm.

To service the HC-2W / RB-3W seals: remove circlip, unscrew the

adapter (attention left hand) and remove the 3 seals. Replace

these with the 3 seals in the “seal kit HC-2W” cat. 68506 ”seal kit

RB-3W” cat 84086.

For all other service and maintenance take the machine to a

RIDGID authorized service center.
