2.1 Foreword
This instruction manual is part of the complete delivery of the drill rig. It provides
information on the design and operation of the drill rig and contains advice and the
measures necessary to keep the rig operational. This instruction manual is no
replacement for thorough training on the drill rig.
This instruction manual should be read in advance by all persons who are to operate
or repair the drill rig or carry out maintenance on it.
See separate instructions for documentation on the rock drill, the diesel engine and
certain other components.
For other questions refer to the local Atlas Copco company office. Addresses and
telephone numbers are in the Maintenance instructions.
2.2 Application
The drilling equipment is designed mainly for drilling blast holes in e.g. quarries and
opencast mines. All other uses are considered inappropriate.
Examples of inappropriate use:
• Lifting loads or people
• Transporting loads or people
• Supporting objects
• Scaling rock
The manufacturer is not liable for damage caused by inappropriate use.
• It is essential the operator has read and comprehends the operator, maintenance
and repair manuals as well as the maintenance schedules.
• The drilling equipment must only be used, maintained and repaired by personnel
well conversant with the equipment and the dangers involved.
• It is essential that personnel observe general and local safety, health and traffic
regulations.
• The manufacturer is not liable to damage caused by any arbitrary changes made
to the drilling equipment.

2.4.2 Wagon frame with track frames
The diesel engine, chassis, dust collector, hydraulic system, air system and boom
system are mounted on the wagon frame.
The wagon frame comprises a frame with the operator's cab/platform mounted on
the left. Controls for tramming and drilling are installed in the operator's cab/plat-
form.
The track frames are carried on journals in the wagon frame. When tramming on
uneven ground the drill rig is balanced by means of two compensating cylinders.
Each track frame has its own service brake. The brakes are operated by two separate
control systems.
The bodywork covers the diesel engine, the compressor, the various lubrication
tanks, the valves and the hydraulic hoses. Inspection covers allow easy access to the
various machine components. The covers are secured in the open position by means
of gas springs.
The dust collector is mounted at the back of the rig on the right-hand side.

This hydraulic drill rig is powered by a turbocharged, water-cooled diesel engine.
The diesel engine is equipped with a monitoring system that includes automatic
shut-down functions.
The drill rig is driven by two traction motors with gears. The traction motors with
gears are mounted on the track frames.
The hydraulic pumps and the compressor are driven by a diesel engine.

2.4.4 Boom system
The boom system consists of boom body, telescopic boom, boom head, feed holder
and associated hydraulic cylinders. The boom system is controlled by directional
valves for positioning the feed with the rock drill at different distances and direc-
tions.
2.4.5 Dust collector
The hydraulically driven dust collector features automatic cleaning and consists of a
filter unit, pre-separator, suction fan and suction hose.
2.4.6 Electrical system
The 24 V electrical system is supplied with current by an alternator and two batter-
ies.
There is a main battery isolation switch in the system which ensures that it is possi-
ble to isolate the batteries from the system.
The electrical system comprises starting equipment, work lighting, electric controls
and safety devices.
The emergency stops are connected in series with the diesel engine cut-out system.
As soon as an emergency stop button/cable is activated, the diesel engine will be
stopped immediately. Reset the emergency stop buttons/cable before restarting the
engine. The engine cannot be started while one of the emergency stops is still acti-
vated.
For further details, see separate wiring diagram.
For details of the diesel engine, see separate diesel engine instructions.
2.4.7 Hydraulic system
The hydraulic system consists of oil cooler, hydraulic oil tank, valves, hoses, and
five hydraulic pumps.
The five hydraulic pumps provide hydraulic pressure as follows:

2.4.8 Air system
The air system consists of the compressor with oil separator, hoses and valves.
The compressor is driven directly by the diesel engine.
The compressor element is lubricated by an air-oil mixture. The mixture is separated
in the oil separator.
The system supplies air for flushing the drill hole, cleaning the dust collector filter
and for the rock drill machine's ECL lubricating system to oiling the drill steel
threads.
