Lubrication

Note!

 Lubricate the tool with a few drops of oil in the air-line connection before using the tool 

for the first time.

• 

For best results, lubricate regularly but sparingly. Oil entering the air-lines will 
lubricate the internal components. 

• 

If a mist lubricator is NOT used, the tool should be lubricated by dropping a little 
oil into the coupling nipple once or twice a day (depending on the level of usage). 
Only a few drops (1-2) of oil are needed at a time. If too much oil is used it will 
collect in the tool and blow out into the air when the tool is used. Bear in mind that 
oil mist in the air is dangerous for your health!

• 

Cold weather operation. In cold or freezing weather, the moisture in the air-lines 
might freeze and create problems. We recommend that you use an air lubricator 
or permanent anti-freeze (ethylene glycol) as a lubricant. Note!  To prevent the 
build-up of frost or ice on the valves or other parts of the tool, which can lead to 
malfunction, you should avoid storing the tool where there is a risk of frost.

Use

• 

The tool is equipped with a switch for reversing the direction of rotation. Turn it to 
the left for anticlockwise rotation (L) and to the right for clockwise rotation (R). Only 
change the direction of rotation when the tool has come to a complete stop.

• 

Set the desired torque level (1-4) by turning the control near the inlet nipple.

• 

Start with the lowest torque and increase if needed.

Protect the environment

Sort your waste and recycle products instead of throwing them away.  
All machines, hoses and packing material should be sorted and  
handled according to local environmental regulations.
