6. Start drill feed. Right-hand multifunction lever forwards through sectors a and f.
7. Low percussion is activated through turning right-hand multifunction lever (anticlock-
wise):
NOTE: Use the drill lever intermittently through sectors a and f until solid rock is
reached.
NOTE: Collaring with feed too high will make the drill bit veer off in the wrong
direction and result in a deviating hole and bent drill string.
8. Drilling can be suspended by moving the right-hand multifunction lever through sec-
tors a and f to the end position. The lever can be released back to neutral once the self-
holding circuit has started. After a few seconds the percussion switches from automatic
to high.

tion, feed, percussion and flushing air).
