n Important!
Always depressurize the equipment before carrying
out any cleaning and maintenance work! Risk of injury!
11.1 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 im-
mediately after you use it.
• Clean the equipment regularly with a damp cloth
and some soft soap. Do not use cleaning agents
or solvents; 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.
11.2 Maintenance work on the pressure vessel/
condensed water (Fig. 1)
m 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 10.7.1).
Open the drain screw by turning counter-clockwise
(looking at the screw from the bottom of the compres-
sor) 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 ves-
sel. If you discover any damage, then please contact
the customer service workshop.
11.3 Safety valve (Fig. 2/Pos. 16)
The safety valve (16) has been set for the highest per-
mitted pressure of the pressure vessel. It is not permit-
ted to adjust the safety valve or remove the connection
lock (16.2) between the exhaust nut (16.1) and its cap
(16.3).
Actuate the safety valve every 30 operating hours but
at least 3 times a year, to ensure that it works when re-
quired. Turn the perforated exhaust nut (16.1) counter-
clockwise to open it and use your hands to pull the valve
rod outwards over the perforated exhaust nut (16.1) to
open the safety valve outlet. Now, the valve audibly
releases air. Then, tighten the exhaust nut clockwise
again.

11.4 Checking the oil level at regular intervals (Fig.
10)
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 (18).
Oil change: we recommend SAE 15W 40 or equivalent.
The original oil filling must be changed after 10 hours
in operation; thereafter the oil must be drained and re-
placed with new oil after every 50 hours in operation.
11.5 Changing the oil (Fig. 10)
Switch off the engine and pull the mains plug out of
the socket. After releasing any air pressure you can
unscrew the oil drain plug (20) from the compressor
pump. 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 vessel. If the oil does not
drain out completely, we recommend tilting the com-
pressor slightly.
When the oil has drained out, re fit the oil drain plug (20).
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 (14.1) until it
comes up to the maximum level. This is marked with a
red dot on the oil level window (18) (Fig. 10 pos. 18.1).
Do not exceed the maximum filling quantity. Overfilling
the equipment may result in damage. Reinsert the oil
sealing plug (14) into the oil filler opening (14.1).
11.6 Cleaning the intake filter (Fig. 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 decrease
the compressor's performance dramatically. Open the
thumb screw (G) to the remove the intake filter.
Then pull off the filter cover (J). Now you can remove
the air filter (L) and the filter housing (K). 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.
11.7 Storage
m Important!
Pull out the mains plug and ventilate the equip-
ment and all connected pneumatic tools. Switch
off the compressor and make sure that it is se-
cured in such a way that it cannot be started up
again by any unauthorized person.
