direction. The screw it open by 1/2 to 1
turn (Figure 3a).
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.
2.6 Maintenance
Interval / No later than Tasks
-- / As needed
-- / after each use
daily / commissioning
Once after 10 h / --
-- / Weekly
50 h / After 6 months
500 h / after 1 year
1,000 h / after 2 years
2,500 h / After 5 years
2.6.1 Before each maintenance task
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.
Clean compressor
Clean filter insert (FDM)
Drain condensate from pressure vessel
Drain condensate from FDM
Check the oil level, add oil if necessary.
Check screw connections
Check intake filter
Check V-belt tension (where applicable)
Clean intake filter
Change oil (1st oil change mineral or synthetic oil) 2.6.7
Change oil (with mineral oil)
Change intake filter
Change check valve and insert
Check screw connections
Change oil (with synthetic oil)
Change V-belts (where applicable)
Change safety valve
2.5.2 Adjusting the working pressure
1. Pull up the adjustment button on the (fil-
ter) pressure reducer (Figure 4a).
2. Rotate clockwise = pressure is in-
creased. Rotate anticlockwise = pressure
is reduced.
3. Read the set working pressure on the
pressure gauge (item 13).
4. Press the adjustment button down to
lock it in place.
2.5.3 After use
1. Switch off the compressor.
2. Disconnect the power supply.
3. Disconnect plug nipple of air hose from
(safety) quick-action coupling (Fig. 3a) .
4. Clean compressor (Chap. 2.6.2), depres-
surise it (Chap. 2.6.1), transport to stor-
age location (Chap. 2.4.1).
2.6.2 Cleaning the compressor
• Clean the cooling fins on the cylinder, cyl-
inder head and aftercooler using com-
pressed air.
• Clean the fan impeller cover on the motor.
2.6.3 Clean FDM insert
1. Depressurise vessel of FDM.
