11 Electrical connection
The electrical motor installed is connected and ready
for operation. The connection complies with the ap-
plicable VDE and DIN provisions. The customer's
mains connection as well as the extension cable used
must also comply with these regulations.
When working with spray attachments and during tempo-
rary use outdoors, the product must be connected to a re-
sidual current circuit breaker with a trigger current of 30
mA or less.
11.1 Damaged electrical connection
cables
The insulation on electrical connection cables is often
damaged.
This may have the following causes:
• Pressure points, where connection cables are passed
through windows or doors,
• Kinks where the connection cable has been improper-
ly fastened or routed,
• Places where the connection cables have been cut
due to being driven over,
• Insulation damage due to being ripped out of the wall
socket,
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not be
used and are life-threatening due to the insulation dam-
age.
Check the electrical connection cables for damage regu-
larly. Ensure that the connection cables are disconnected
from electrical power when checking for damage.
Electrical connection cables must comply with the appli-
cable VDE and DIN provisions. Only use connection ca-
bles of the same designation.
The printing of the type designation on the connection ca-
ble is mandatory.
Safety information for replacing damaged or defective
mains connection cables
Connection type Y
If it is necessary to replace the mains connection cable,
this must be done by the manufacturer or their represen-
tative to avoid safety hazards.
11.2 Important information
In the event of overloading, the motor will switch itself off.
After a cool-down period (time varies) the motor can be
switched back on again.
11.3 AC motor
Connections and repair work on the electrical equipment
may only be carried out by electricians.
• Before commissioning, ensure that the mains voltage
matches with the operating voltage on the type plate.
• Extension cables up to 25 m long must have a cross-
section of 1.5 mm².
12 Cleaning and maintenance
WARNING
Have maintenance and repair tasks that are
not described in this operating manual, car-
ried out by a specialist workshop. Use only
original spare parts.
WARNING
Improper maintenance or cleaning work can
cause injuries!
WARNING
The product may start unexpectedly and cause inju-
ries and burns during cleaning, repair and mainte-
nance work.
– Switch the product off.
– Pull out the mains plug.
– Allow the product to cool.
– De-pressurise the compressor.
Note:
Release overpressure in the compressor by switching off
the compressor and using up the compressed air still in
the pressure vessel, e.g. with a compressed air tool run-
ning at idle or with an air blow gun.
12.1 Cleaning
• Keep protective devices, air vents and the motor
housing as free of dust and dirt as possible. Rub the
product clean with a clean cloth or blow it off with
compressed air at low pressure. We recommend that
you clean the product directly after every use.
• Clean the product at regular intervals using a damp
cloth and a little soft soap. Do not use any cleaning
products or solvents; they could attack the plastic
parts of the product. Make sure that no water can pen-
etrate the product interior.
• We recommend that you clean the product directly af-
ter every use.
• The hose and injection tools must be disconnected
from the compressor before cleaning. The compressor
must not be cleaned with water, solvents or similar.
12.2 Maintenance
12.2.1
• The safety valve is set to the maximum permissible
pressure of the pressure vessel.
• It is not permitted to adjust the safety valve or remove
the connection lock between the exhaust nut and its
cap.
• Actuate the safety valve every 30 operating hours but
at least 3 times a year to ensure that it works when re-
quired.
1. To open the outlet of the safety valve (5), turn the per-
forated drain nut (5a) anticlockwise. Now, the valve
audibly releases air.
2. Then, tighten the exhaust nut (5a) clockwise again.
