motor start-up is jeopardized as a result of
stiffness.
6.6 On/Off switch (8)
To switch on the compressor, press the green knob
(8).
To switch off the compressor, press the red knob (8)
in again. (Fig. 2)
6.7 Adjusting the pressure: (Fig. 1)
You can adjust the pressure on the pressure
gauge (6) using the pressure regulator (7).
The set pressure can be taken from the quick-
lock coupling (5).
6.8 Setting the pressure switch
The pressure switch is set at the factory.
Switch-on pressure 8 bar
Switch-off pressure 10 bar
7. Cleaning and maintenance
Important!
Pull the power plug before doing any cleaning
and maintenance work on the appliance.
Important!
Wait until the compressor has completely cooled
down. Risk of burns!
Important!
Always depressurize the tank before carrying out
any cleaning and maintenance work.
7.1 Cleaning
Keep the safety devices free of dirt and dust as
far as possible. Wipe the equipment with a clean
cloth or blow it with compressed air at low
pressure.
We recommend that you clean the appliance
immediately after you use it.
Clean the appliance 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 appliance. Ensure that no
water can get into the interior of the appliance.
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.
7.2 Condensation water (Fig. 4)
The condensation water must be drained off each
day by opening the drain valve (11) (on the floor of
the pressure vessel).
Important! The condensation water from the
pressure vessel will contain residual oil.
Dispose of the condensation water in an
environmentally compatible manner at the
appropriate collection point.
7.3 Safety valve (10)
The safety valve has been set for the highest
permitted pressure of the pressure vessel. It is
prohibited to adjust the safety valve or remove its
seal.
7.4 Check the oil level at regular intervals
Place the compressor on a level and straight surface.
The oil level must be between the two marks MAX
and MIN on the oil oil level window (Fig. 14/Item 16).
Changing the oil: Recommended hydraulic oil: SAE
15W/40 or an alternative of the same quality.
It should be refilled for the first time after 100 hours
of operation. Thereafter the oil should be drained and
refilled after every 500 hours in service.
7.5 Changing the oil
Switch off the engine and pull the mains plug out of
the socket. After releasing any air pressure you can
unscrew the oil drainage screw (15) 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
recommend tilting the compressor slightly.
Dispose of the old oil at a drop-off point for old
oil.
When the oil has drained out, re-fit the oil drainage
screw (15). Fill new oil through the oil filler opening
(14) until it comes up to the required level. Then
replace the oil sealing plug (14).
7.6 Retensioning the V-belt (Figs. 15-17)
Pull out the power plug and remove the safety
guard for the V-belt.
Slacken the four motor fixing screws (A).
Shift the motor until the V-belt is tensioned to the
point where it can still be depressed by approx.
1-2 cm at the longest free position.
Retighten the motor fixing screws (A) and refit
the safety guard for the V-belt.
7.7 Cleaning the intake filter (1)
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 compressorʼs performance
dramatically. Undo the two Allen screws (B). You can
