Overload Protection; Maintenance; Technische Daten - RIDGID HC-1 Gebrauchsanleitung

- Wet drilling: insufficient water.
- Wet drilling: Material is very abrasive and/or heavily reinforced: use special bit.
- Drilling machine not held steadily.
- Drilling machine is hammering: don't use the hammering system for core drilling.
5. Segments of the diamond core are losing side clearance
- Drilling machine not held steadily.
- Bit spindle or adapters are damaged.
- Core bit is damaged or bent.
- Insufficient water.
- Material is too abrasive: use special bit.
- Dry drilling: Cutting/drilling dust is building up and jamming the core: regularly clear
the hole or use the dust extraction.
6. Segment loss
- Core bit doesn't run concentric.
- Drilling/cutting debris is building up and is jamming the core.
- Material cannot be drilled dry.
- Core bit is being forced too hard: reduce feed pressure.
- Insufficient cooling water.
7. Segments are folding in or out
- Excessive pressure.
- Too high speed.
- The drilling machine is left on "hammer".
8. Core is lodged within the diamond bit
- The heat has expanded the material which is now lodged in the bit: let it cool down,
eventually use water.
- The core has broken within the diamond bit: remove core.
- The bit has lost its side clearance: check that the bit, machine etc. is running
concentric. If necessary re-tip the diamond bit.
9. No water flowing out of the bore hole (wet drilling)
- Water swivel, drill spindle or water supply are blocked; free the blockage.
- Material within bit is blocking the water: remove core from the bit.

MAINTENANCE

Keep the tool clean and prevent any accumulation of dust or particles 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 5mm.
To service the HC-2 W 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.
For all other service and maintenance take the machine to a RIDGID authorized service
center.

If unit is continuously overloaded the thermal
overload will disconnect the supply.
Electronic protection will disconnect supply if unit is
overloaded. After unit has stopped remove load and
restart.
This lights up when you overload the motor.
