Actuate the safety valve every 30 operating hours but
at least 3 times a year, to ensure that it works when
required.
Turn the perforated exhaust nut (8.1) counterclockwise
to open it and use your hands to pull the valve rod out-
wards over the perforated exhaust nut (8.1) to open the
safety valve outlet. Now, the valve audibly releases air.
Then, tighten the exhaust nut clockwise again.
10.4 Checking the oil level at regular intervals (Fig.
5)
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 (16).
Oil change: we recommend SAE 15W 40 or equiva-
lent.
The original oil lling 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.
10.5 Changing the oil (Fig. 1, 5)
Switch o the engine and pull the mains plug out of the
socket. Remove the oil sealing plug (14). After releas-
ing any air pressure you can unscrew the oil drain plug
(17) from the compressor pump.
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 completely, we recom-
mend tilting the compressor slightly. When the oil has
drained out, re-t the oil drain plug (17).
Dispose of the old oil at a drop-o point for old oil.
To ll in the correct quantity of oil, make sure that the
compressor stands on an even surface.
Fill new oil through the oil ller opening (F) until it
comes up to the maximum level.
This is marked with a red dot on the oil level window
(16). Do not exceed the maximum lling quantity. Over-
lling the equipment may result in damage.
Reinsert the oil sealing plug (14) into the oil ller open-
ing (F).
10.6 Cleaning the intake lter (Fig. 1, 6, 10)
The intake lter prevents dust and dirt being drawn in.
It is essential to clean this lter after at least every 300
hours in service. A clogged intake lter will decrease
the compressor’s performance dramatically. Open the
screw (D) to remove the intake lter.
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 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.
10.2 Maintenance work on the pressure vessel
(Fig. 1)
m Important!
To ensure a long service life of the pressure vessel
(11), drain o the condensed water by opening 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 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 dam-
age each time before using. Do not use the compres-
sor with a damaged or rusty pressure vessel. If you
discover any damage, then please contact the custom-
er 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 suitable
collection point.
10.3 Safety valve (Fig. 2)
The safety valve (8) has been set for the highest permit-
ted pressure of the pressure vessel. It is not permitted
to adjust the safety valve or remove the connection lock
(8.2) between the exhaust nut (8.1) and its cap (8.3).
