OPERATION
Compressed air supply

Check that the relevant compressor provides sufficient air flow.

The tool must always be turned off when it is connected to the compressed air supply.

Normal operating air pressure for the tool is 6.2 bar. Excessively high pressure and contaminated
air cause the tool to wear unreasonably quickly, and can also entail a risk of personal injury or
damage to property.

Every day, drain off any water from the compressor’s air container and empty the air hoses of any
condensate that has accumulated. Otherwise, water from the air hoses can penetrate the tool and
damage it.

Clean the air intake filter cartridge each week.

If hoses are very long (normally longer than 8 metres), the line pressure must be increased to
compensate for the pressure drop. The minimum inner diameter of the hose is 1/4”. Couplings
must have the same inner diameter. An air hose with an inner diameter of 3/8” is normally
recommended for optimum tool function.

Use appropriate hoses and couplings. We do not recommend connecting quick-release couplings
directly to the tool, as they can cause malfunction as a result of vibration. Instead, connect a hose
to the tool and install a quick-release coupling between the air hose from the compressor and the
anti-vibration hose that is attached to the tool.

Check each hose for wear before use. Make sure that all connections are secure.
Use
1. Lubricate the tool before use as instructed in the section on care and maintenance.
2. Install the brass holder and the handle on the tool (fig. 1).
3. Open the quick chuck by turning it anti-clockwise by hand. Insert a drill in the chuck and tighten by
turning clockwise by hand. Check that the drill is correctly inserted and secured before using the
tool. Only use drills whose permitted speed is at least as high as that of the tool (fig. 2.3).
4. Remove the cover from the air intake and connect the air hose to the tool. Set the air pressure to
6.2 bar (fig. 4).
5. Move the direction selector (8) down to position F and press the trigger. The tool starts to rotate
(fig. 5).
6. Reverse the drill out of the hole by moving the direction selector up to position R and pressing the
trigger (fig. 6).
