Danger! High voltage

Operate device in dry environ-

ment only.

Operate device only on a power

source complying with the following

requirements:

− outlets properly installed, earthed

and tested;

− fuse protection in accordance

with the technical specifications.

Position power cable so it does not

interfere with the work and is not

damaged.

Always check to see that the device is

switched OFF before plugging in.

Protect power cable from heat,

aggressive liquids and sharp edges.

Do not stop the compressor by

unplugging, but switch OFF using the

switch.

Unplug after use.

4.2 Generating compressed

air

1. Start device (23) and wait until the

max. tank pressure is reached

(compressor shuts off).

The tank pressure is indicated by

the tank pressure gauge

(24).

2. Set pressure regulator (22) to

required working pressure. The cur-

rent working pressure is indicated

by the regulated pressure gauge

(21).

A

Caution!

The regulated pressure may

not be set higher than the max. work-

ing pressure of the connected air

tools!

3. Connect air hose to compressed air

• Check all screwed connections for

tightness, tighten if necessary.

• Check power supply cable for dam-

age, if necessary have replaced by

a qualified electrician.

Every 50 operating hours

• Check air filter element (26) of com-

pressor pump, clean if necessary.

• Check oil level (27) of compressor

pump, top up if necessary (28).

• Drain condensate from pressure

vessel (30).

A

Caution!

The condensate contains oil

and must be disposed at a proper col-

lecting point.
