Drilling
Starting the rock drill
1. Open the main valve for compressed air.
2. Open the cock for the flushing water.
3. Adjust the feed control lever to give a suitable feed force for collaring the hole.
4. Align the rock drill so that the working tool touches the desired collaring point.
5. Move the throttle lever forward a little, which will start water flushing,
percussion and rotation.
6. Collar the hole with reduced feed force.
7. Move the throttle lever fully forward once the working tool has gained a
secure footing in the rock.
8. Adjust the feed force by means of the control lever so that the maximum
penetration rate is obtained.
Note! Do not bend the working tool as this will increase wear of the shank bushing
and piston. Furthermore, it can also affect drilling efficiency and increase the
risk of working tool breakage.
Stopping the rock drill
Pull the throttle lever backwards, which will stop percussion, rotation and flushing
water.
Re-positioning the pusher leg
1. Switch off the rock-drill percussion and flushing by means of the throttle lever.
2. Press the trigger, whereupon the piston rod is pulled back into the pusher-leg
cylinder automatically.
3. Re-position the pusher leg.
4. Release the trigger, whereupon the piston rod will move outwards again.
5. Move the throttle lever forward into the working position.
Note! The feed control lever does not need to be touched throughout this operation.
Blow-cleaning the drill hole
CAUTION
Move to the side and cover your eyes before starting to blow-clean the drill hole.
When blow-cleaning, particles and dirty flushing water can emerge at speed from
the drill hole.
h
Always wear impact resistant eye protection with side protection to avoid
injury.
h
Make sure that no co-workers are in range when blow-cleaning.
If powerful blow-cleaning of the drill hole is required, turn the throttle lever fully
backwards beyond the stop position for extra blowing, whereupon the rock drill
stops. This can be done during drilling. When the drill hole is clean, turn the throttle
lever forwards again to re-start the rock drill.
