Start and stop

Starting the rock drill

1. Open the main valve for compressed air.
2. Move the feed forward with reduced feed force.
3. Start the impact mechanism with reduced
percussion and collar the hole with reduced feed
force.
4. Apply full throttle to the impact mechanism once
the drill steel has gained a secure footing in the
rock.
5. Adjust the feed force so that the maximum
penetration rate is obtained.

Stopping the rock drill

1. Switch of flushing when drilling is complete.
2. Switch off the impact mechanism or reduce
percussion, before reversing the feeding direction
of the rock drill.

Operating

Drilling

♦ Use protective shoes, gloves, helmet, ear
protectors and impact resistant eye protection with
side protection.
♦ Hold the inserted tool firmly against the work
surface before starting the machine.

When taking a break

♦ If the rock drill has been converted to water
flushing, water pressure needs to be shut off
before air pressure. Run the rock drill for a few
seconds to clean out water and moisture after the
water has been shut off.

Regular maintenance is a basic requirement for the
continued safe and efficient use of the machine.
