OPERATING INSTRUCTIONS

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 – 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.

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.
