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:
The Scalers work best at 5 to 7 bar pressure. The air should be clean, dry and lubricated. Install a FRL unit as
close to the tool as operation will allow.
