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.
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.
CAUTION : This is a safety critical procedure. Double check the
torque settings after assembly.
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 accidentally be pressurised / over pressu-
rised 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.
