Trigger

When the trigger (A) is pushed in, the feed force stops abruptly and the setting
on the feed control lever is overridden. The piston rod in the pusher leg retracts
automatically. This function is used for example to adjust the height of the rock
drill, when rigging up the pusher leg, or when there is a tendency to jam. When the
trigger is released, the feed control setting is activated again.

Oil regulating valve

Oil dosing is controlled by means of a screwdriver.
Check that sufficient lubrication is obtained by putting your hand in front of the
exhaust port while adjusting the regulating valve. If the hand is covered by a thin
film of oil after a few seconds, the lubricator has been correctly adjusted.
The amount of oil going into the rock drill increases when turning the valve counter
clockwise, and it decreases when turning the valve clockwise. Oil consumption is
2.5–6 ml/minute.
Note! Tighten the nut after regulation.
Note! To much oil will have negative effects on the operation whilst to little will
result in damage to parts as the temperature rises during operation.
