NSTRUCTIONS FOR PARKING AND TOWING
1. Before towing the compressor, ensure that the towing equipment
of the vehicle matches the towing eye. The height of the towing
device of the vehicle must be 800 ± 150 mm (31.2 ± 5.9 in).
2. Place the compressor as level as possible; however, it can be
operated temporarily in a slant position not exceeding 15 ¡.
3. Never move the compressor with air hoses connected to the air
outlet valves.
4. Always apply the hand brake when parking the compressor.
5. Always lift the unit using the lifting eye. The lifting eye is
provided on top of the compressor under a small door. Open the
door from the outside of the compressor and fix the hook of the
hoist to the lifting eye. Lifting acceleration and retardation shall
be kept within safe limits.
Helicopterlifting using the lifting eye is not allowed.
B
EFORE STARTING
1. Check the engine and compressor oil levels. Check the engine
coolant level. Check the fuel level and top up if necessary.
2. Drain water and sediment from the fuel filters.
3. Empty the air filter dust traps.
4. Attach the air line(s) to the closed air outlet valve(s). Connect
the safety cable and do not exert external force on the outlet
valve(s)

and all lamps for normal readings.
Avoid to let the engine run out of fuel. If it happened,
priming will speed up the starting.
2. Check the adjustment of the regulating valve, i.e. whether the
valve starts decelerating the engine when reaching the preset
working pressure in the air receiver.
3. Check the air outlet temperature (TG) of the compressor
element. Close the door after checking.
S
TOPPING
1. Close the air outlet valve(s).
2. Press the
