4.1 Safety
instructions
Danger
Mortal danger caused by sudden start-
up of the system.
•
Systems which are in the standby op-
erating mode are liable to start auto-
matically at any time.
•
All parts installed behind the check valve
(e. g. aftercooler, pressure switch) are not
released automatically from pressure.
•
Not all electrical cables are de-energised
when the system is switched off!
•
Before commissioning, ensure that no
person can be injured by the starting
compressor.
•
Never point compressed air at persons.
•
Do not use compressed air for breathing
without corresponding treatment.
•
Use mounting parts and devices down-
stream from the compressor which have
been designed for the maximum operating
pressure of the compressor.
•
Do not reach into the rotating wheels
when the compressor is operational.
•
Touch the compressor system at the on
and off switch only during and shortly af-
ter operation. Hot surface can cause se-
vere injuries.
•
Switch the compressor off immediately in
case of faults.
•
Keep combustible materials away from
the compressor system.
•
Operate the compressor only in conjunc-
tion with a suction filter and if all parts of
the casing are closed.
•
Operate the compressor only at the per-
missible operating pressure of the pres-
sure reservoir.
•
Tighten the screw connections of the
pressure pipes.
•
Wear tight-fitting work cloths when han-
dling the compressor.
•
Wear goggles and ear muffs when working
with compressed air.
•
Wear a hair net to protect long hair and
remove any lose jewellery.

intervals.
•
Keep domestic animals and children away
from the compressor system.

Switch the compressor off when not
needed.

4.3
Start-up after an extended idle
time
During an extended idle time, the complete oil
content flows into the compressed air / oil
reservoir. If this has happened, the screw
compressor is no longer lubricated.
!
Dismount intake regulator.
!
Fill approx. 1 litre compressor oil into the
air intake fitting.
!
Mount intake regulator.
Do not mix different types of oil. In
choosing the oil you want to use, refer
to the corresponding BLITZ specifica-
tions (refer to chapter 6.2 “
Checking
and topping up the oil level
“).
