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.
6. Check that the rock drill and pusher leg are
receiving enough lubrication. Fill the lubricator if
necessary.
7. Drain the water separator.
8. Check the air and water pressure. Make sure
that the water pressure is at least 1 bar lower
than the air pressure.
Periodic maintenance
After each operating period of approximately 100
working hours or three times a year the machine
must be dismantled and all parts be cleaned and
checked. This work must be performed by authorized
staff, trained for this task.
Damage patterns
Worn or broken parts must always be studied
carefully before they are replaced. They can give
important information about the condition of the drill
and about the way it is used and maintained.
CauseProblem
The parts have been subjected
to excessive heat. This can be
caused by insufficient
lubrication or idling
Steel parts are a bluish colour
See aboveSteel parts have small almost
microscopic fissures on the
wear surfaces
See aboveIrregular cavities on the surface
of bronze parts
Secondary damageCutting marks
Dirt inside the drill
Interior misalignment due to
uneven tension of the side
bolts
Storage
● Always oil the rock drill well, before you put it into
storage.
● Always store the machine in a clean and dry place.
● Make sure that no foreign matter enters the
machine.
● Protect the chuck using the plastic plug provided
with the machine. Alternatively, use a wooden plug
or a clean piece of cotton waste.
● In the case of long-term storage, pour a quantity
of oil directly into the rock-drill's air intake and then
turn on the air briefly. This will protect the machine
from corrosion.
