Fitting The Air Filter

1.  Remove the transportation 

cover from the air filter 

connection with a screwdriver.

2.  Attach the supplied air filter by 

screwing it in clockwise.

Checking The Oil Level

1.  Place the compressor on a level surface.

2.  Unscrew the oil sealing plug and allow the 

oil level to settle for a few minutes. 

3.  Screw the breather plug into place.

Note: 

The compressor should be operated 

with the breather plug in place. The oil 

sealing plug may be used for transport or 

storage of the compressor.

4.  Check that the oil level is 

between the ‘MAX’ and ‘MIN’ 

marks on the oil level window.

Note: 

The oil level may appear 

lower when first unboxed due 

to movement of the unit during 

transit. Leave the compressor 

on a level surface for several 

minutes with the oil sealing plug 

removed before checking the 

oil level.

5.   If the oil level is below the ‘MIN’ mark, refer to the Maintenance 

section - Changing The Oil and follow the directions for refilling the 

oil in the compressor.

OPERATION

Switching The Compressor On/Off

1.  To switch the compressor on, 

pull the on/off switch to the ‘I’ 

position. Allow the motor to 

run and the tank to fill up.

Note:

 You can monitor the 

pressure in the tank with the tank 

pressure gauge.

Note:

 

The compressor will automatically cut off when the tank 

pressure reaches 8bar and will automatically start up again when the 

tank pressure drops to 6bar.

2.  To switch the compressor off, press the on/off switch to the ‘0’ 

position.

Thermal Overload Protection

This Air Compressor is fitted with thermal protection and will shut off 

to protect the compressor from overheating.

The compressor may also have shut off due to reaching max. cut 

off pressure. If you are unsure, use an attached blow gun to release 

some of the pressure until the tank pressure gauge drops below 6bar. 

If the motor does not automatically start up, the unit has overloaded 

and the thermal protection has activated.

If the thermal protection activates, switch off the compressor and 

allow the compressor to cool down for 15 minutes. Before attempting 

to restart the air compressor, check that the oil level is sufficient and 

that the air filter is not blocked. Refer to the Maintenance section to 

clean air filter or add oil if needed.

 

WARNING! 

ALLOW THE AIR COMPRESSOR TO 

COOL BEFORE ATTEMPTING ANY MAINTENANCE.

WARNING! 

DO NOT CONTINUE USE OF THE UNIT 

IF THE THERMAL PROTECTION ACTIVATES AGAIN 

IMMEDIATELY AFTER THE RESET.
