Checking for wear

1. Check the wear in the chuck bushing using the
Atlas Copco (3091 0038 00) gauge (22 mm).
If the wear limit has been exceeded, the drill steel
shank will wear more quickly, or become
deformed. This will lead to stoppages and
increased drill-steel consumption.
2. Check the tightness of the side-bolt nuts
(A).Tighten to a torque of 130 Nm.
3. Check the tightness of the throttle lever. Tighten
to a torque of 60 Nm.
4. Check the rock drill's connection to the pusher
leg.
5. Check the hoses, couplings and controls for
leakage and damage.
