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.
9.2 Maintenance work on the pressure
vessel (Figure 1)
Important! To ensure a long service life of the
pressure vessel (7), drain off the condensed
water by opening the drain valve (9) each time
after using. Release the vessel pressure first
(see 9.7.1). 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
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 contact the customer
service workshop.
Important!
The condensed water from the pressure
vessel will contain residual oil. Dispose of
the condensed water in an environmentally
compatible manner at a suitable collection
point.
9.3 Safety valve (Figure 3)
The safety valve (19) has been set for the
highest permitted 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 sufficient force until
you can hear the compressed air being
released. Then release the ring again.
9.4 Checking the oil level at regular
intervals (Figure 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 (Fig.
18). Oil change: we recommend SAE 15W 40
or equivalent. 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.
9.5 Changing the oil (Figure 1,10, 11)
Switch off the motor and pull the mains plug out
of the socket. After releasing any air pressure
(see 9.7.1) you can unscrew the oil drain screw
(18) 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
container. If the oil does not drain out
completely, we recommend tilting the
compressor slightly. When the oil has drained
out, refit the oil drain screw (18).
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 (21)
until it comes up to the maximum level. This is
marked with a red dot on the oil level window
(18) (Figure 11). Do not exceed the maximum
filling quantity. Overfilling the equipment may
result in damage. Reinsert the oil sealing plug
(16) into the oil filler opening (21).
9.6 Cleaning the intake filter (Fig. 2, 3, 12)
The intake filters (15) prevent the drawing in of
dust and dirt. It is essential to clean these filters
after at least every 300 hours in operation. A
clogged intake filter will decrease the
compressor’s performance dramatically.
Remove the intake filters from the equipment by
unscrewing them. The filter housing (D) is
plugged on the filter cover (C) and can be
removed by applying slight pressure to the filter
cover. Carefully tap out the air filters (F), the
filter cover and the filter housing. Then blow out
these parts with compressed air (approx. 3 bar)
and reinstall in reverse order. The filter cover
and the filter housing have different latching
positions. When you assemble the intake filter,
make sure that the intake opening faces down.
