Maintenance instructions
1. General
22
The objective of these maintenance instructions is to detect and rectify faults at an
early stage so that breakdowns, costly secondary damage and accidents can be pre-
vented. Regular maintenance is a precondition for planning necessary interruptions in
operation such as reconditioning and repairs. This allows maintenance to be carried
out when most suitable with regard to production instead of causing complete break-
down.
Hydraulic systems
General
Hydraulic systems are sensitive to impurities and pollutants. The environment in
which rock drilling equipment usually works is generally unsuitable as a place for
repairing hydraulic components. Work on the hydraulic system at the worksite should
therefore be limited to what is absolutely essential. The components should then be
repaired in a suitable environment, see the section Hydraulic workshops .
Observe the following points to avoid breakdowns and interruptions in operation due
to fouled hydraulic oil:
• Keep the rig clean. Hose it down at regular intervals, preferably with a grease sol-

• have well-trained mechanics.
Replacement of hydraulic hoses
A high percussion pressure, vibration and other mechanical interference puts high
demands on the hydraulic hoses.
When replacing hydraulic hoses, check that they are replaced with hydraulic hoses:
• with the correct crimped couplings
• of the correct quality class
• with the correct dimension
All hydraulic pressure hoses have crimped couplings and should therefore be pur-
chased ready-made directly from Atlas Copco. Quality classes and hose dimensions
are specified in the spare parts catalogue for the relevant rig. Make also sure that hose
connections are clean, in good condition and well tightened.
Welding
Note
It is important to consult Atlas Copco for approval of welding and choice of elec-
trodes.
The following must be observed when welding:
• Turn off the supply of current to the unit.
• Disconnect the cables from the generator and battery.
• Grind off rust and paint from the area that is to be welded and carefully prepare the
joint.
• Weld in a dry area.
• Connect the welding earth cable to a clean surface as close as possible to the weld-
ing area. Avoid welding close to bearings and bushes. If these cannot be removed,
connect earth cables on both sides of the weld.

• Alterations and reinforcements must not be made without previous consultation
with Atlas Copco.
