Check the play in the brake linkage [7] and re–adjust if
necessary.
Important
Check the brake actuators and cables [11]. The brake actuators
must not be pre–tensioned.
Excessive operation of the handbrake lever, which may have
been caused by worn brake linings, must not be corrected by
re–adjusting (shortening) the brake linkage [7]
Re–adjustment
The handbrake lever [1] should be engaged forcefully several
times to set the braking system.
Check the setting of the brake equalisation assembly [8], which
should be at right angles to the pulling direction.
Check the play in the brake linkage [7] again, ensuring that there
is no play in the brake linkage and that it is adjusted without
pre–tension
Check the position of the hand brake lever [1], cable [5] (with
little play) and the compression spring [9] (only slight
pre–tension). The start of resistance of the handbrake lever
should be approximately 10–15mm above the horizontal
position.
Final test
Check the fastenings on the transmission system (cables,
brake equalisation system and linkage)
Apply the handbrake while rolling the machine forward, travel of
the handbrake lever up to 2/3 of maximum is allowed.
Check the handbrake cable [5] for a small amount of play and
adjust if necessary (Variable height only)
Check the compression spring [9] for slight pre–tensioning.
LUBRICATION
The engine is initially supplied with engine oil sufficient for a
nominal period of operation (for more information, consult the
Engine section of this manual).
CAUTION: Always check the oil levels before a new machine
is put into service.
If, for any reason, the unit has been drained, it must be
re–filled with new oil before it is put into operation.
ENGINE LUBRICATING OIL
The engine oil should be changed at the engine
manufacturer’s recommended intervals. Refer to the Engine
section of this manual.
ENGINE LUBRICATING OIL SPECIFICATION
Refer to the Engine section of this manual.
ENGINE OIL FILTER ELEMENT
The engine oil filter element should be changed at the engine
manufacturer’s recommended intervals. Refer to the Engine
section of this manual.
COMPRESSOR LUBRICATING OIL
Refer to the SERVICE/MAINTENANCE CHART in this
section for service intervals.
NOTE: If the machine has been operating under adverse
conditions, or has suffered long shutdown periods, then more
frequent service intervals will be required.
WARNING: DO NOT, under any circumstances, remove any
drain plugs or the oil filler plug from the compressor
lubricating and cooling system without first making sure
that the machine is stopped and the system has been
completely relieved of all air pressure (refer to STOPPING
THE UNIT in the OPERATING INSTRUCTIONS section of this
manual).
Completely drain the receiver/separator system including
the piping and oil cooler by removing the drain plug(s) and
collecting the used oil in a suitable container.
Replace the drain plug(s) ensuring that each one is secure.
NOTE: If the oil is drained immediately after the machine has
been running, then most of the sediment will be in suspension
and will therefore drain more readily.
CAUTION: Some oil mixtures are incompatible and result in the
formation of varnishes, shellacs or lacquers which may be
insoluble.
NOTE: Always specify INGERSOLL–RAND Pro–Tec

RUNNING GEAR WHEEL BEARINGS
Wheel bearings should be packed with grease every 6
months. The type of grease used should conform to
specification MIL–G–10924.
