uAlways read the machine Safety Manual before start maintenance work on the Rock
Drill.
uAlways observe local regulations.
uAlways carry out a documented risk analysis and take the necessary precautions be-
fore maintenance work.
uOnly use clean, calibrated tools in good condition.
uOnly use approved handling and working equipment in good condition.
uAlways use personal protective equipment.

the main switch turned off and locked.
uAttach WORK IN PROGRESS signs according to local regulations, or at least at the
main switch and operator's station.
WARNING
Serious injury or death
Serious danger when working on the hydraulic system!

uAdjacent moving units should always be anchored before working on a system part.
uAlways stop work if there is an unforeseen or suspected risk.
1.2 The Purpose of This Publication
The objective of these instructions is to detect and rectify faults at an early stage so that
breakdowns, costly secondary damage and accidents can be prevented. Regular mainte-
nance is a precondition for planning necessary interruptions in operation such as recondi-
tioning and repairs. This allows work to be carried out when it's most suitable with regard to
production instead of causing complete breakdown.
