is under pressure. Before connecting the compressor to an energy source, make sure that the
switch of the pressure switch is in the OFF position.
Before carrying out any repair, inspection, maintenance, cleaning or component replacement
work, the compressor must be disconnected from the mains supply and the pressure released
from the boiler.
ever use the compressor near water or in a humid environment.
Always wear protective glasses or eye protection. ever point the compressed air jet at your own
body or at other persons.
ever operate the compressor unless all guards (e.g. guards, belt guards, safety valve) are prop-
erly installed. If maintenance or repair work necessitates the removal of the guards, make sure
that they have been properly reattached before restarting the compressor.
ever place your hands, fingers or any other parts of your body near moving parts.
ORK ITH COMPRESSED AIR AND BLO GUNS
Compressors and lines reach high temperatures during operation. Avoid touching these parts as
this can cause burns.
The air sucked in by the compressor must be kept free of gases, vapours and admixtures, which
can lead to fire or explosion in the unit.
When releasing the hose coupling, be sure to hold the hose coupling piece by hand to avoid injury
from the hose coming out.
Always wear protective goggles when working with the blow gun. Blown foreign bodies and parti-
cles can easily cause injuries.
ever point the blow gun at persons.
ever clean clothes on the body with the blow gun.
ORKING ITH PAINT SPRAYERS
Do not use varnishes or solvents with a flash point of less than 21 °C.
ever heat solvents or paints.
When processing liquids that are harmful to health, filter devices such as view masks are required
for protection. Please observe the information on further protective measures provided by the
manufacturer of these substances.
Do not smoke in the entire working area during the spraying process. Paint vapours are highly
flammable.
Paint vapours are harmful to health. Therefore do not store or consume any food or drinks in the
work area.
ote that the working area must be more than 30 m³. Sufficient air circulation during spraying and
drying is absolutely necessary.
PVC hoses must not be used with liquids such as white spirit, butyl alcohol or ethylene chloride,
as this can lead to a reduced service life of the compressed air hose.
Ensure that the intake air is clean, dry and dust-free.
Do not place the compressor in a wet or humid room.

BEFORE COMMISSIONING
1) Place the compressor in a clean, dry and well-ventilated place.
2) Use only 230 V operating voltage with a maximum fluctuation of 5 %.
3) At the oil level, check whether it is within the red display circuit.
4) Use SAE30 gear oil when the ambient temperature is above 10 °C. If the ambient temperature
is below 10 °C, use SAE10 gear oil.
5) Open the drain valve, adjust the pressure and let the compressor run for 10 minutes without
any equipment connected so that all moving parts lubricate themselves.
SETTINGS
1) The compressor is secured by a pressure switch. As soon as the max. boiler pressure is
reached, it switches off automatically. As soon as the pressure has fallen below the minimum
rate, it switches on again. This pressure setting was made ex factory and must not be
changed. As soon as the engine switches off, the compressed air in the discharge pipe should
be released by the release valve under the switch. This works automatically and is necessary
to avoid damaging the engine. The pressure can be varied by turning the screw bolt.
2) The discharge pressure can be adjusted by the pressure regulator.
3) When you turn off the compressor, turn it off with the On/OFF switch.
SPECIFIC SAFETY INSTRUCTIONS
1) First remove the gear oil cover and insert the red plug.
2) ever unscrew a connection when the tank is under pressure.
3) ever disconnect an electrical connection when voltage is applied to the mains plug.
4) ever change the settings of the safety relief valve.
5) Make sure that the mains voltage does not deviate from 230 V by more than 5 %.
6) Do not pull the mains plug to stop the compressor. Always use the On/Off switch on the compres -
sor.
7) If the release valve does not work when the engine stops, try to correct the fault before operating
the compressor and damaging the engine.
8) The oil must always be clean and you must make sure that the oil level is correct.
9) Always disconnect the mains plug when unscrewing a valve.
MAINTENANCE
1) The first oil change should take place after the first 10 hours.
2) Afterwards an oil change every 20 working hours is sufficient.
3) Every 60 working hours, open the drain cock to let condensation water out of the tank.
4) Clean the air filter every 120 working hours.
