General safety regulations
• Read and comprehend the manual before the rig and its equipment is operated.
• The rig must only be used for the purposes described in these instructions, see
operator's instructions, Applications.
• Special attention must be paid to safety and all the warnings in the manual.
• It is essential that personnel observe general and local safety, health and traffic
regulations.
• Always use a helmet, hearing protection, protective safety glasses, safety gloves
and other necessary safety equipment when you are in the vicinity of the rig.
• Pay attention to the rig's warning signals when you are in the vicinity of the rig,
see Safety, Warning signals .
• The drilling equipment must only be used, maintained and repaired by personnel
well conversant with the equipment and the dangers involved.
• Checks and adjustments that are necessary when the rig is in operation must be

carried out by at least two persons. One person must then be present at the operat-
ing station and have a good view of the work.
• Extra caution must be exercised when changing a drill bit or drill steel see opera-
tor's instructions, Drilling.
• All work on tyres and rims may only be carried out by a qualified maintenance

been maintained in accordance with the maintenance schedule in force, that all
controls, emergency stop and fire extinguishers are working satisfactorily, that
warning signs and safety labels are in the correct locations, are clean and fully leg-
ible. Report damage and deficiencies immediately. Do not operate the system
before all faults have been rectified. See also operator's instructions, Daily

when parking and at the end of every shift. Inspect the emergency stop and safety
equipment as well.
• All work performed with the rig involves impact on the surrounding environment,
e.g. in the form of vibrations and landslide. Work must always be carried out with
great caution and in accordance with safety directives in force.
• Engine exhaust fumes are poisonous. Good ventilation is essential when the diesel
engine is running.
• During service work, stay only within areas indicated on the rig's engine cover. Do
not step onto opened service covers.
• When maintenance work is carried out under a raised cab, the cab must be secured
in the raised position.

Working in the risk area of the rig
Description
Fault finding or working in the rig's risk area involves risk. Accordingly, always
carry out the fault finding or the work with great care and accuracy. For further safety
regulations, see Safety, Safety regulations.
Note
Pay attention to the rig's warning signals when you are in the vicinity of the rig, see
Safety, Warning signals.
Specific expertise
Specific expertise is required for:
• the electrical system
- Diagnosis of and work on the electrical system must only be performed by
appropriately authorised electricians.
• tyres and wheels
- All work on tyres and wheels must be carried out by specially trained mainte-
nance personnel as it is important to ensure that correct procedures are fol-
lowed and that the right tools are used.

- Diagnosis of and work on the climate unit refrigerant system must only be per-
formed of specially trained maintenance personnel.
Steps to take
All work in the rig's risk area requires certain precautions:
• The electric motors and diesel engine must be switched off during fault finding

and work within the rig's risk area. For exceptions see section Special procedures.
• Hydraulic, pneumatic and water systems must be depressurised with diagnosis and
work in the rig's risk area. For exceptions, see section, Special procedures.
• The rig's electric power supply must be disconnected and locked during fault find-
ing and work within the rig's risk area (plug unplugged and socket locked with a
padlock). For exceptions, see section Special procedures.
• When diagnosis or work in the rig's risk area is to be performed, all components
which can be moved or continue moving must be secured, by supports or strap-
ping before the diagnosis or work is started.
Special procedures
Exercise extra caution and accuracy when fault finding diagnosis or other work is to
be performed at the same time as when one or more of the following points are appli-
cable:
• the electric motors are started
• the diesel engine is started
• the hydraulic pumps are running
• the rig's power supply is connected (plug is connected)
• the hydraulic system is pressurised
• the pneumatic system is pressurised
• the water system is pressurised
If one or more of the above criteria must be fulfilled in order to carry out fault finding
or certain work then special steps must be taken:
• The work must be carried out by at least two people, one of which must be at the
operating station and have a good view of the work.
