COMMISSIONING
Upon receipt of the unit, and prior to putting it into service, it
is important to adhere strictly to the instructions given below in
PRIOR TO STARTING.
Ensure that the operator reads and understands the decals
and consults the manuals before maintenance or operation.
Ensure that the position of the emergency stop device is
known and recognised by its markings. Ensure that it is
functioning correctly and that the method of operation is known.
Running gear drawbar (European Area) – Machines are
shipped to some areas with the drawbar removed. Fitting
involves four nuts / bolts to secure the drawbar to the axle and
two bolts to fit the drawbar to the front of the machine with the
saddle and spacer block.
Support the front of the machine, fit the wheel chocks to stop
the machine moving and attach the drawbar. Refer to the torque
value table in the MAINTENANCE section of this manual for the
correct torque values.
CAUTION:
This is a safety critical procedure. Double check the torque
settings after assembly
Fit the propstand and coupling. Remove the supports and
set the machine level.
Before towing the unit, ensure that the tyre pressures are
correct (refer to the GENERAL INFORMATION section of this
manual) and that the handbrake is functioning correctly (refer to
the MAINTENANCE section of this manual). Before towing the
unit during the hours of darkness, ensure that the lights are
functioning correctly (where fitted).
Ensure that all transport and packing materials are
discarded.
Ensure that the correct fork lift truck slots or marked lifting /
tie down points are used whenever the machine is lifted or
transported.
When selecting the working position of the machine ensure
that there is sufficient clearance for ventilation and exhaust
requirements, observing any specified minimum dimensions (to
walls, floors etc.).
Adequate clearance needs to be allowed around and above
the machine to permit safe access for specified maintenance
tasks.
Ensure that the machine is positioned securely and on a
stable foundation. Any risk of movement should be removed by
suitable means, especially to avoid strain on any rigid discharge
piping.
Attach the battery cables to the battery(s) ensuring that they
are tightened securely . Attach the negative cable before
attaching the positive cable.
WARNING: All air pressure equipment installed in or
connected to the machine must have safe working
pressure ratings of at least the machine rated pressure,
and materials compatible with the compressor lubricant
(refer to the GENERAL INFORMATION section).
WARNING: If more than one compressor is connected to
one common downstream plant, effective check valves and
isolation valves must be fitted and controlled by work
procedures, so that one machine cannot accidently be
pressurised / over pressurised by another.

WARNING: If flexible discharge hoses are to carry more
than 7 bar pressure then it is recommended that safety
retaining wires are used on the hoses.
