Important information

In the event of an overloading the motor will switch itself

off. After a cool-down period (time varies) the motor can

be switched back on again.

Damaged electrical connection cable

The insulation on electrical connection cables is often

damaged.

This may have the following causes:

• Passage points, where connection cables are passed

through windows or doors.

• Kinks where the connection cable has been improp-

erly fastened or routed.

• Places where the connection cables have been cut

due to being driven over.

• Insulation damage due to being ripped out of the wall

outlet.

• Cracks due to the insulation ageing.

Such damaged electrical connection cables must not be

used and are life-threatening due to the insulation dam-

age.

Check the electrical connection cables for damage

regularly. Make sure that the connection cable does not

hang on the power network during the inspection.

Electrical connection cables must comply with the ap-

plicable VDE and DIN provisions. Only use connection

cables with the marking „H05VV-F“.

The printing of the type designation on the connection

cable is mandatory.

AC motor

• The mains voltage must be 230 V~

• Extension cables up to 25 m long must have a cross-

section of 1.5 mm2.

Connections and repairs of electrical equipment may

only be carried out by an electrician.

Please provide the following information in the event of

any enquiries:

• Type of current for the motor

• Machine data - type plate

10. Cleaning, maintenance, and storage

m Important!

Pull out the power plug before doing any cleaning and

maintenance work on the equipment. Risk of injury from

electric shock!

m Important!

Wait until the equipment has cooled down completely!

Risk of burns!

m Important!

Always depressurize the equipment before carrying out

any cleaning and maintenance work! Risk of injury!

10.1 Cleaning

• Keep the equipment free of dirt and dust as far as

possible. Wipe the equipment with a clean cloth or

blow it down with compressed air at low pressure.

• We recommend that you clean the equipment imme-

diately after you use it.

• Clean the equipment regularly with a damp cloth and

some soft soap. Do not use cleaningagents or sol-

vents; these may be aggressive to the plastic parts

in the equipment. Ensure that no water can get into

the interior of the equipment.

• You must disconnect the hose and any spraying tools

from the compressor before cleaning. Do not clean

the compressor with water, solvents or the like.

10.2 Maintenance work on the pressure vessel (Fig.

m Important! To ensure a long service life of the pres-

sure vessel (8), drain off the condensed water by open-

ing the drain valve (10) each time after using. Release

the vessel pressure rst (see 10.7.1). Open the drain

screw by turning counter-clockwise (looking at the

screw from the bottom of the compressor) so that all

the condensed water can run out of the pressure ves-

sel. Then close the drain screw again (turn it clockwise).

Check the pressure vessel for signs of rust and damage

each time before using. Do not use the compressor with

a damaged or rusty pressure vessel. If you discover

any damage, then please contact the customer service

workshop.

m Important!

The condensed water from the pressure vessel will con-

tain residual oil. Dispose of the condensed water in an

environmentally compatible manner at a suitable collec-

tion point.

10.3 Safety valve (Fig. 3)

The safety valve (17) has been set for the highest per-

mitted pressure of the pressure vessel. It is prohibited

to adjust the safety valve or remove its seal. Actuate

the safety valve from time to time to ensure that it works

when required. Pull the ring with sufcient force until

you can hear the compressed air being released. Then

release the ring again.

10.4 Checking the oil level at regular intervals (Fig.

11)

Place the compressor on a level and straight surface.

The oil level must be between the MAX and MIN marks

on the oil level window (12).

Oil change: we recommend SAE 15W 40 or equivalent.

The original oil lling must be changed after 100 hours

in operation; thereafter the oil must be drained and re-

placed with new oil after every 500 hours in operation.

10.5 Changing the oil (Fig. 1,10,11)

Switch off the engine and pull the mains plug out of the

socket. Remove the oil sealing plug (15). After releasing

any air pressure you can unscrew the oil drain plug (12)

from the compressor pump (13).

To prevent the oil from running out in an uncontrolled

manner, hold a small metal chute under the opening and

collect the oil in a vessel. If the oil does not drain out com-

pletely, we recommend tilting the compressor slightly.
