PARKING INSTRUCTIONS 

When parking a compressor, secure prop (1) or nose wheel
to support the compressor in a level position. Place the
compressor as level as possible; however, it can be
operated temporarily in an out-of-level position not
exceeding 15°. If the compressor is parked on sloping
ground, immobilize the compressor by placing wheel
chocks in front of or behind the wheels. Locate the
compressor upwind, away from contaminated wind-
streams and walls. Avoid recirculation of exhaust air from
the engine. This causes overheating and engine power
decrease.

TOWING INSTRUCTIONS

Before towing the compressor, make sure that the towing
equipment of the vehicle matches the towing eye or ball
connector
The drawbar should be as level as possible and the
compressor and towing eye end in a level position. Secure
nose prop (1) in the highest position. Attach safety chains/
cables in a crisscross manner to the tow vehical. This will
help prevent the towbar from contacting ground in event
of a breakaway. Connect road lights when applicable.

LIFTING INSTRUCTIONS

When lifting the compressor, the hoist has to be placed in
such a way that the compressor, which must be placed
level, will be lifted vertically. Use the lifting bale provided
to lift the unit

Before Starting

1. Before initial start-up, prepare battery for operation if 

not already done.

2. With the compressor standing level, check the level of 

the engine oil. Add oil, if necessary, to the upper mark 

on dipstick. Consult the Engine Operation Manual for 

the type and viscosity grade of the engine oil.

3. Check the level of the compressor oil. The pointer of oil 

level gauge (OLG) should register in the green range. 

Add oil if necessary. 

4. Check that the fuel tank contains sufficient fuel. Top 

up, if necessary. Consult the Engine Operation Man-
ual for the type of fuel.

5. Check coolant level in overflow bottle. Top off coolant 

if necessary. Consult engine’s operation manual for 

water/coolant specifications.

6. Drain any water and sediment from the fuel filter until 

clean fuel flows from the drain cock.

7. Press vacuator valve (VV) of the air filter to remove 

dust.

8. Check the air filter service indicator (VI). If the red part 

shows completely, service or replace the filter element. 

Reset the indicator.

9. Open an air outlet valve (AV) to allow air flow to the 

atmosphere.

Lifting acceleration and retardation must

be kept within safe limits (max. 2g).
Helicopter lifting is not allowed.

If the compressor is to be connected to a 

common compressed air system, fit an 

appropriate check valve between 

compressor outlet and air system. Observe 

the right mounting position/direction!
