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 replace-
ment 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/rotation unit, the diesel
engine and certain other components.
For other questions refer to the local Epiroc company office. Addresses and tel-
ephone numbers are in the Maintenance instructions.

General system description
General description of the drill rig
This drill rig is a fully diesel-hydraulic drill rig designed for surface drilling
applications such as in quarries and on construction sites.
The drill rig consists of the following main components: (See illustration under
General Description).

Operator's instructions
1. General
Wheeled chassis frame
The diesel engine, chassis, dust collector, hydraulic system, air system and boom sys-
tem are mounted on the wagon frame.
The 4 wheels are driven by two steering axles with integrated brake.
The body covers the diesel engine, the compressor, the different lubrication tanks, the
valves and the hydraulic hoses. Inspection hatches facilitate access to the different
machine components. All the hatches lock in the open
position with a pneumatic spring.
The dust collector is mounted at the back of the rig on the right-hand side.
Power pack
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 drilling carriage is driven by 2 steering axles connected to each other by a
universal joint and powered by a hydraulic motor.
The hydraulic pumps and the compressor are driven by a diesel engine.
Boom system
The boom system consists of inner/outer boom bodies, 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 directions.
Dust collector
The hydraulically driven dust collector features automatic cleaning and consists of a
filter unit, pre-separator, suction fan and suction hose.
Electrical system
The 24 V electrical system is supplied with current by an alternator and two batteries.
The electrical system comprises starting equipment, work lighting, electric controls
and safety devices.

Operator's instructions
1. General
The emergency stop buttons/cables 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 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.
Hydraulic system
The principal components of the hydraulic system comprise oil cooler, hydraulic oil
tank, valves, hoses and four hydraulic pumps.
The four hydraulic pumps create hydraulic pressure in order to control the different
functions. The table below indicates which hydraulic pump controls which function.
Table: Description of hydraulic pump function
The hydraulic oil tank is located in the centre of the drilling carriage.
The radiator on the right side of the drilling carriage cools the water of the engine,
the intercooler and the oil compressor. The radiator on the left side cools the
hydraulic oil.
(For more information, see the separate hydraulic system drawing)

Hydraulic pumps
Hydraulic pump 1
Main hydraulic system pump 1 is a variable-displacement piston
type. The pump supplies hydraulic power to the following
functions:
Winch,
tramming,
impact,
feed drill rotation
Hydraulic pump 2
Hydraulic pump 2 supplies hydraulic oil to provide power to the boom.
Boom swing,
boom lift,
boom extension
Hydraulic pump 3
Hydraulic pump 3 supplies hydraulic oil to power the
Steering,
lubricating pump,
dct,
stability jacks,
feed swing,
feed dump,
feed extension,
roll over,
drill steel support,
RAS
Hydraulic pump 4
Hydraulic pump 4 supplies hydraulic oil to power the oil cooler motor.

2 30 62 260
3 10 26 260
4 7 26 150
Air system
The air system consists of the compressor with oil separator, hoses and valves. The
compressor is belt-driven from 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 in the bore hole, cleaning of
the dust collector filter and the rock drill lubrication system and ECL.
