Residual risks and protective measures
Electrical residual risks:
1. Direct electrical contact:
Risk of electric shock
To be used in electrical networks with a safety switch
against stray current (RCD-FI 30 mA) only.
2. Indirect electrical contact:
Risk of electric shock
To be used in electrical networks with a safety switch
against stray current (RCD-FI 30 mA) only.
Thermal residual risks:
1. Burns, chilblains:
Contact with the cylinder head and pressure lines
may cause burns.
Avoid both of these construction elements.
Exposure to noise:
1. Hearing damage:
Long stay in the immediate vicinity of the appliance
may damage hearing.
Wear headphones.
Neglecting the ergonomic principles:
1. Human behaviour / erroneous behaviour:
Compressed air current may lead to serious injuries.
Never hold the current in body holes.
Compressed air may cause tanks and tyres to break.
Do not exceed the max. filling size.
Installation and first start-up
Pic.2+3+4:
1.
Remove the oil tank transport protection (if applicable)
pic. 3
2.
Insert the attached oil gauge or plug instead.
3.
Oil gauges or plugs, pic. 4 (failing to do so will increase
in the engine case and oil will spirt).

Electrical connection; grounded connections to be used
only:
a)230 V appliances are supplied with plugs fitted with a
ground contact
Pic. 5
The following must be considered as far as 230 V
appliances are concerned:
If a too long extension cable with a too small cross-section
is used, voltage will drop, which may result in a more difficult
starting and increased engine load. If possible, we
recommend connecting the engine cable directly to the outlet
and using longer air hoses (another measure: see the winter
operation).
Recommended cable cross-section values for all 230 V
appliances:
Length within app. 10 m = 1.5
Length within app. 20 m = 2.5
Oil level check (for oil compressors only):
Oil may leak when the appliance is transported. Please check
the oil level on the aperture or using an oil gauge (more
information at a similar description with a picture)
Winter operation of compressors
The following must be considered in colder seasons
when operating the compressors: Oil gets thicken and its
viscosity increases with low temperatures in the engine case.
This makes first appliance starting before warm-up more
difficult. Proceed as follows when facing difficulties:
1.
Reduce any pressure in the air jet to zero.
2.
Open the drainage screw on the bottom part of the air
jet.

mm
2
mm
3.
Unless being absolutely necessary, do not use any
extension cable!
4.
Switch on the compressor and let it run (without any
extension cable). With the drainage screw open, let it run
for app. 2-3 minutes to enable air to leak and thus
pressure to reduce. The appliance will warm in these 2-3
minutes to enable further operation.
5.
After 2-3 minutes, close the drainage screw. The air jet
can now be filled and pressure increased.
6.
Change oil – use 5W40 synthetic oil for light running
or, as alternative, SAE 80 gearbox oil.
7.
If the compressor does not start despite all the effort, put
it out of operation for half an hour to one hour in a
tempered room to warm up.
8.
Please contact the customer service centre for more
difficulties.
All documents necessary for proper operation are
included in the supply (see the simple regulation for
pressure vessels). When used for industrial purposes,
an inspection is necessary before the appliance is used
for the first time under the operating safety regulation.
Safety instructions for first start-up
Procedure
1.
Switching compressors on and off:
The On/Off button (rotary and pull switch) is up on the
pressure switch cover at all compressors. Switch
positions are marked as "0" and "I". When plugging, the
switch must be in the "0" position, then the appliance
may be started. When switching the appliance off, put
the switch to the "0" position first and then unplug the
compressor. Never switch the appliance off by
unplugging as this would prevent depressurising.
Caution: Empty the condensate at regular intervals
(monthly) (see the drainage screw).
Operation
1.
Using pneumatic tools and devices
Please follow the air consumption information of
manufacturers. Check whether the power of your
compressor is enough to operate the given device. The
air consumption table details may be used as
benchmark values.
2.
Servicing and maintenance
Check regularly the oil level and add some if necessary.
Clean the air filter if dirty; wash the filter inserts in a
detergent - do not use thinners or solvents. If
necessary, order new inserts from the customer service
centre.
3.
Air jet drainage:
Regardless of the type of compressor, the drain valve is
placed on the bottom part of the air jet at all
compressors. Drain only if the air jet is under pressure.
4.
Opening the drain valve:
Unscrew the screw closure to such extent the air
deflates. Any accumulated water is blown out with the
air.
5.
Rusty water:
Rusty water may run out when the air jet is initially
drained. Rusty water is caused by clips fallen to the
tank when producing air jet and disintegrated
subsequently. This is quite normal and water gets
clearer after several drains.
Oil filler neck and oil level checking (for oil compressors)
At appliances fitted with an oil gauge (1), add oil after
removing the gauge (1) to the appropriate hole (2) and check
the level using the gauge marking. At appliances with an
aperture and marking in the glass, remove the oil filler neck
and add oil up to the aperture marking. If the aperture has no
rd
marking, 2 3
– 3 4
oil drainage screw is always on the side or bottom part of the
engine case.

th
filling of the aperture is appropriate. The
