Warning
Always check for damaged or loose hoses and
fittings before operation. Whipping hoses can
cause serious injury.
2. Blow through the air hose
Every day, before using the drill, blow through
the air hose to clear it of accumulated dirt and
moisture.
3. Fill the lubricator with oil
Note! Check that the chuck and drill-steel shank
are always covered with a film of oil.
Note! Always use a recommended lubricant.
Lubricant Recommendation
Air tool oil Use a mineral-based air tool oil

4. Calibrate the correct air and water
pressure
Use the Atlas Copco No. 9090 0550 80 pressure
gauge to check the water and air pressure when
the rock drill is running.
Air pressure
Ensure that the compressor can deliver the
required air volume at 4–6 bar at the tool.
► High pressure causes rough operation and
damage.
► Low pressure results in a slow drilling speed.

Safety and operating instructions
The pressure gauge is equipped with a needle
which is pressed into the hose to measure the
pressure inside.
Note! Make sure that the water pressure is at
least 1 bar lower than the air pressure
otherwise the water can enter the impact
mechanism. For example if the air pressure
is 6 bar, the water pressure must be below
5 bar to prevent water entering the impact
mechanism.
