1. Introduction
Interval
Division
The maintenance intervals for various rig components are based on percussion hours
and diesel engine hours.
Percussion hours
Percussion hours apply to components that are mainly in operation during drilling.
Examples; rock drill, feeder and boom.
Percussion hours can be read on the hour counter in the electric cabinet.
For information on rock drill maintenance intervals, see separate documentation for
the rock drill in question.
Diesel engine hours
Diesel engine hours apply to components that are primarily in operation when the rig
is moved, e.g. diesel engine, transmission and brake system.
Diesel engine hours can be read on the control panel from the hour counter.
Lubricant
For information on recommended lubricants, see maintenance instructions Lubri-
cants, coolants and propellants.
Tightening torques
Tightening torques for most screw unions are specified in the Atlas Copco standard,
see maintenance instructions General. For other screw unions where special tighten-
ing torques apply, the torque is specified in the maintenance instructions for the com-
ponent in question.
