The holding circuit has now ceased and the feed can be controlled manually in sec-
tors (f) and (a).

8.1.2 Boom/feed adjustment while drilling
CAUTION
Risk of injury
The equipment can be damaged
u The drill rig can only be interrupted in drilling mode or with emergency stop
If the boom/feeder for any reason must be readjusted while drilling, this can be done by re-
setting the remote control box. Switch S130, position (a). The multi-function levers will then
go to positioning mode and drilling can continue.
!
NOTE: Drilling can only be terminated by resetting the remote control box to drilling po-
sition or activating the emergency stop.
!
NOTE: After 5 seconds, the positioning functions will be deactivated and only percus-
sion stop will work. To continue drilling, reset the mode switch to drilling position.
8.2 Checks during drilling
Monitor the drilling and pay particular attention to the points below. If anything is abnormal,
stop drilling and rectify the problem or ask service personnel to investigate the cause.
Abnormal impact hose vibration. Check the pressure in the rock drill accumulators.
Check that the shank adapter is sufficiently lubric-
ated.
Lubricating oil/air should leak out from the shank
adapter. Lubricating oil pressure should be
between 2 and 10 bar on the ECL pressure
gauge.
Abnormal leakage from the rock drill.
Note that the shank adapter has a "float position",
i.e. it is pressed out about 4-6 mm from the sub-
frame.
If damper pressure is lower than 35 bar or higher
than 120 bar, percussion will stop automatically
( For drill rig COP 1800/2150/2550/4050 series )
Stop drilling immediately and ask service person-
nel to investigate.
If the rig is equipped with ECL collection, the ECL
collection lamps on the display should be
checked.
