Operation & Maintenance Guide
(For 12.7mm A/F Square body and releasing slot at back type Chisel)
OPERATION:
Chisel Scalers are rugged, dependable tools designed to give years of satisfactory service. Follow the instructions
mentioned here to enhance the life and performance of your scaler.
DAILY BEFORE OPERATION:
Disconnect and pour in 1 to 2 ounces of recommended oil into the tool and reconnect hose blowing out any
accumulated dirt in the hose line before connecting.
LUBRICATION REQUIREMENT:
Always install a line lubricator on the air line as close to the tool as possible. A filter regulator lubricator unit
(FRL) is strongly recommended. Keep the lubricator bowl topped up with oil and check that the oil is reaching the
tool. Running without lubrication is likely to cause damage the components causing premature replacement.
AIR SUPPLY:
Tool should not be operated at air pressure below 5.5 Bar (80psi) and above 6.9 bar (100psi).The correct
operating pressure is 6.2 bar (90 psi).
Ensure that only 3/8" (10 mm) bore airline is used and all couplings are tight, leakproof and in good condition.
The air should be clean, dry and lubricated. Install a FRL unit as close as operation will permit.
RECOMMENDED LUBRICANTS:
ABOVE 270C 800F 50C-270C 400F-800F BELOW 50C 400F
