Always use clean, dry air at 90 PSI maximum air pressure. Dust, corrosive fumes and / or
excessive moisture can ruin the motor of an air tool.
Use a clean lubricated air supply that will give a measured air pressure at the tool of 90 PSI with
the trigger fully depressed.
Use recommended hose size and length. It is recommended that the tool is connected to the air
supply as shown in figure A.
Do not connect the tool to the air line system without incorporating an easy to reach and operated
shut off valve.
It is strongly recommended that an air filter, regulator, lubricator (FRL) is used as shown in
figure A as this will supply clean, lubricated air at the correct pressure to the tool. Details of such
equipment can be obtained from your supplier. If such equipment is not used then the tool should be
lubricated by shutting off the air supply to the tool, depressurising the line by pressing the trigger on
the tool.
Disconnect the air line and pour into the intake bushing a teaspoon (5 ml) of a suitable pneumatic
motor lubricating oil preferably incorporating a rust inhibitor. Reconnect tool to air supply and run
tool slowly for a few seconds to allow air to circulate the oil.
If tool is used frequently lubricate on daily basis and if tool starts to slow or lose power.
Some models allow the regulation of the applied torque within its working conditions.
To modify the applied torque:
The tool must be disconected from the air supply
1. Remove the front housing (unscrew cw direction)
2. Take out the clutch assy.
3. Place the hex key (1/4") in the head conexion and hold it firmly. Use a 17mm wrench and tighten
or loosen the piece next to the sping of the clutch.
Tightening this piece it will increase the force on the spring, and the clutch will operate at higher
torques.
4. Assembly the tool following steps 3 to 1.
5. Connect air supply and test the torque of the tool.
1) Inspect the air hose for cracks or other problems. Replace the hose if worn.
2) Never point an air hose at another person.
3) Disconnect the tool when not in use, or before performing service or changing accessories.
4) Use proper hoses and fittings. Never use quick-change couplings attached at the tool. Instead,
add a hose and coupling between the tool and the air supply. The recommended hook-up is
shown in figure A. Pneumatic tools operate on a wide range of air pressures. For maximum
efficiency and longer tool life, the pressure of the air supplied to these tools should not exceed
the rated PSI at the tool when the tool is running.
Using a higher than rated pressure will cause faster wear and drastically shorten the tool's life. A
higher air pressure can also cause an unsafe condition. The inside diameter of the hose should be
increased to compensate for unusually long air hoses (over 25 feet). Minimum hose diameter should
