2. During air extraction, oil deposits in the
form of droplets can be seen at the upper
sight glass. Dosing: 1 droplet oil at 300
– 600 l/min air consumption. Readjust If
necessary and check regularly.

2.5 Operation

Do not overload the compressor: do not
exceed the max. number of switching cy-
cles and the ratio of operating time to
standstill!
2.5.1 Insert
Switch on the compressor at the ON/OFF
switch (item 10). The compressor starts up
and switches off automatically at maximum
pressure.

1. Swtich on the compressor at the ON/OFF
switch (item 10). Disconnect the power
supply.
2. Depressurise the compressor: using the
blow gun, blow out all pressure from the
vessel.
Only drain oil if the unit has been suffi-
ciently cooled.
