3. Application
General
The drilling equipment is designed exclusively for drilling holes in tunnels and
mines. All other uses are considered to be inappropriate.
Examples of inappropriate use:
• Lifting and transporting loads and 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.

4. Daily inspection
General
Note
To ensure optimal utilisation of the rig and its equipment, it is of utmost importance
that daily maintenance is carried out in accordance with our recommendations.
The objective for the daily inspection of the rig is to:
• detect faults at an early stage
• facilitate servicing
• allow scheduled maintenance and planned reconditioning work to be performed
• prevent costly secondary damage
• prevent breakdowns
• prevent personal injury
Note
Do not operate the rig or the rig equipment until all faults have been rectified.
Checklist
Note
As soon as a fault is detected, note it and report to maintenance personnel.
• Always begin by making an inspection round.
• Check safety devices
• Check hoses and cables
• Check oil levels
• Check the lubrication points.
• Keep your eyes open for possible leakage and wear.
• Pay attention to any faults in the function of the controls.
Daily maintenance
• Rinse off the rig with water, especially the feeder and other parts that have been
exposed to drill cuttings or rock debris
• See maintenance schedule for each component.

Designation Function Description
H11 Indicator lamp for parking brake The lamp shines if the parking brake is applied.
H12 Indicator lamp for transmission The lamp shines if the transmission fluid pressure
is too low or if its temperature is too high. The
parking brake is also applied. Contact maintenance
personnel.
H13 Indicator lamp for brake
pressure
Indicates that the hydraulic oil pressure in the brake
circuit is too low. If the lamp shines, the rig should
not be operated. Contact maintenance personnel.

H14 Indicator lamp for hydraulic oil
level
This lamp shines if the level of fluid in the hydraulic
oil tank is too low. The hydraulic oil must be topped
up immediately.
H15 Indicator lamp for fan belt This lamp shines if the fan belt breaks. The belt
must be replaced immediately. Contact
maintenance personnel.
H16 Indicator lamp for diesel engine
lubricating oil pressure
This lamp shines if the pressure is too low. If this
occurs, the engine must be switched off
immediately and the cause rectified by
maintenance personnel.
H17 Indicator lamps for engine
temperature
This lamp comes on if the temperature is too high.
The engine must be switched off immediately and
maintenance personnel contacted if the lamp
comes on during operation.
H18 Indicator lamp for battery
charging
Under normal driving conditions, the lamp should
be out to indicate the batteries are charging. The
lamp is on when the ignition is on. Contact
maintenance personnel if the lamp comes on while
driving.
