Always switch off the main control valve on the air inlet hose to
prevent unintentional start of the rock drill�
Maintenance
Regular maintenance is a prerequisite for machine safety� Replace
damaged and worn components in good time� For a major service
to the machine, contact your nearest authorized workshop�
Check the machine and tools for wear and damage at regular
intervals� Do not use very worn or damaged tools�
When cleaning mechanical parts with a solvent, make sure that
you comply with current health and safety regulations and ensure
that there is sufficient ventilation�
Daily maintenance, regular checking of wearing parts and carrying
out repairs in good time prevents breakdowns and increases the
service life of the machine�
• Always oil the rock drill and pusher leg well, before you put
them into storage�
• Store in a clean and dry place�
• Make sure that no foreign matter enters the machine�
• Protect the chuck using a wooden plug or a clean piece of cotton
waste�
• Always hose down and wipe clean the rock drill and pusher leg
after use�
• 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�
Once a shift (after 8 hours of operation)
• Check the wear in the chuck bushing� If the wear limit has been
exceeded, the working tool shank will wear more quickly, or
become deformed� This will lead to stoppages and increased
working tool consumption�
• Check the tightness of the side-bolt nuts�
• The tightening torque shall be 150 Nm�
• Check the rock drill's connection to the pusher leg�
• Check the hoses, couplings and controls for leakage and dam

age�
• Check that the rock drill and pusher leg are receiving enough
lubrication� Fill the lubricator as necessary�
• Drain the water separator�
• Check the air and water pressure� Make sure that the water pres
-
sure is at least 1 bar lower than the air pressure�
Once a week (after 40 hours of operation)
Carry out a basic check of all functions of the drilling equipment�
Once a month (after 200 hours of operation)
• Send the rock drill to a workshop for inspection� The local operat-
ing conditions will determine whether or not this is a suitable
interval for overhauling the drill�
• Dismantle and clean the lubricator�
• Clean out the water separator�
Differences between original parts and
pattern parts
When buying a part, the first thing to do is to verify that the part is
an Atlas Copco part� Most parts can be identified�
Every day
Before undertaking any maintenance or changing the insertion
tool on pneumatic machines, always switch off the air supply and
bleed the machine by depressing the start and stop device then
disconnect the air hose from the machine�
• Clean and inspect the machine and its functions each day before
the work commences�
• Conduct a general inspection for leaks and damage�
• Check that the air inlet nipple is tightened and that the claw
coupling is free from damage�
• Check the function of the throttle handle� Make sure that it
moves freely up and down�
• Check the function of the retainer� Make sure that it locks the drill
steel�
• Change damaged parts immediately�
• Replace worn components in good time�
• Check the through bolts of the machine� Make sure that they are
tightened�
• If the machine is equipped with a silencer, check for damage�
Checking for wear
1� Check the wear in the chuck
bushing using the Atlas Copco
gauge 90002668 (22 mm),
90002669 (25 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 80 Nm�
3� Check the rock drill's connection
to the pusher leg�
4� Check the hoses, couplings and controls for leakage and dam
-
age�
5� Check that the rock drill and pusher leg are receiving enough
lubrication� Fill the lubricator if necessary�
6� 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�
Selection of spare parts
This machine is a heavy-duty rock drill; there are strict require-
ments on selecting spare parts� Use only genuine parts for
replacement, to ensure stable performance� Do not use pattern
parts, which not only have a short working life but also cause con-
sequential damage to other parts, due to differing measurements
and methods of manufacturing�
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�
