10.2 Maintenance work on the pressure vessel
(Fig. 1)
m Important! To ensure a long service life of the
pressure vessel (8), drain off the condensed water by
opening the drain valve (10) each time after using.
Release the vessel pressure first (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 pres-
sure vessel. 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 con-
tact the customer service workshop.
m Important!
The condensed water from the pressure vessel will
contain residual oil. Dispose of the condensed water
in an environmentally compatible manner at a suita-
ble collection point.
10.3 Safety valve (Fig. 3)
The safety valve (17) has been set for the highest
permitted pressure of the pressure vessel. It is pro-
hibited 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 suffi-
cient force until you can hear the compressed air be-
ing 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 sur-
face. 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 equiva-
lent. The original oil filling must be changed after 100
hours in operation; thereafter the oil must be drained
and replaced 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 un-
controlled manner, hold a small metal chute
under the opening and collect the oil in a ves-
sel. If the oil does not drain out completely,
we recommend tilting the compressor slightly.
When the oil has drained out, re-fit the oil drain plug
(12).
Dispose of the old oil at a drop-off point for old oil.
To fill in the correct quantity of oil, make sure that the
compressor stands on an even surface. Fill new oil
through the oil filler opening (19) until it comes up to
the maximum level.
This is marked with a red dot on the oil level win-
dow (12) (Fig. 11). Do not exceed the maximum fill-
ing quantity. Overfilling the equipment may result in
damage. Reinsert the oil sealing plug (15) into the oil
filler opening (19).
10.6 Cleaning the intake filter (Fig. 3, 12, 13)
The intake filter prevents dust and dirt being drawn
in. It is essential to clean this filter after at least every
300 hours in service. A clogged intake filter will de-
crease the compressor's performance dramatically.
Open the screw (E) to remove the intake filter(2x).
Then pull off the filter cover (D). Now you can remove
the air filter (F). Carefully tap out the air filter, filter
cover and filter housing. Then blow out these parts
with compressed air (approx. 3 bar) and reinstall in
reverse order.
10.7 Storage
m Important!
Pull out the mains plug and ventilate the equipment
and all connected pneumatic tools. Switch off the
compressor and make sure that it is secured in such
a way that it cannot be started up again by any unau-
thorized person.
m Important!
Store the compressor only in a dry location which
is not accessible to unauthorized persons. Always
store upright, never tilted! Oil may leak out!
10.7.1 Releasing excess pressure
Release the excess pressure by switching off the
compressor and using the compressed air which
is still left in the pressure vessel, e.g. with a com-
pressed air tool running in idle mode or with a blow-
out pistol.
