Air fitting and clack valve
Pic. 6
1. Air fitting (2): Air ducting (2) at all compressors is
connected using a quick-acting coupling. Both reduced
pressure and complete pressure from the air jet may be
drawn.
2. Clack valve: The clack valve is located at the end of the
main air ducting, at the air input to the air jet. The
connection point is different for various types of
compressors.
Ducting goes from this valve to the valve to make starting
easier.
3. Pressure-relief valve: Depending on the compressor
type, it is located on the pressure switch (4), on the
pressure control valve or on the air jet. The pressure-relief
valve responses to any malfunction of the pressure switch
(4) and thus limits the pressure in the air jet to the max.
cut-off pressure + 1 bar!
4. Pressure control valve (1): To set the currently needed
pressure, please press the regulator up and set the
requested pressure + 1 bar on the air gauge. To lock the
pressure control valve (1), press the regulator down
again. If necessary, provide additional regulation after the
first operating cycle in the same way.
Safety instructions for the operator
Use the appliance only after careful reading and
•
understanding of the Operating Instructions.
Please follow all safety instructions specified in the
•
Operating Instructions.
Behave responsibly towards other persons.

Inspections and servicing
IMPORTANT: After app. half an hour to
one hour of operation, please check the cylinder head screws
and tighten them if necessary. Torque: max. 10 - 20 Nm/by
hand force. Later: cylinder head screws and all other screwed
connections on should be checked every 200 - 300 operating
hours and tightened if necessary.
Servicing
Clean the filter on the suction side if dirty or replace it. After
operating the appliance for some time, the condensate must
be emptied by opening the drain valve on the air jet. IN case
of continuous operation, this should be done every 4-6 weeks.
If the appliance is used for short works, empty the condensate
.
once in 3 months
Belt tension at compressors with a V-belt
must be checked at regular intervals (every 4-6 weeks).
Oil level check and oil change
The appropriate oil level may be checked on the oil aperture
(if applicable) or on the oil gauge.
Maximum level = a small bubble or the upper marking on the
oil gauge must be seen in the aperture.
Minimum level = oil must not get under the red point in the
middle of the aperture or the lower marking on the oil gauge.
Specified oil = universal oil - 15 W 40 (100 operating hours)
or Güde 5W40 compressor oil, Art. No. 40056 (300-500
operating hours)
Oil change:
After running in, i.e. after 100 operating hours, oil should be
changed for the first time.
Another oil change after app. 300 - 500 operating hours.
Oil adding: unscrew the filler neck and add oil using a funnel.
Oil drainage: Unscrew the drain screw and let oil run out.
Air filter:
Check the air filter app. once a quarter. Foam filters are
washed with a detergent. Replace the filter if heavily
contaminated with paint or varnish!
Folded filters to be blown by compressed air or replaced if
necessary; not to be washed!
CAUTION:
If more oil is added than the maximum level, spring-energised
seals may get untight. The surplus oil along with the
compressed air will shortly get to the air jet – more oil is thus
consumed - until reaching the common state. If oil does not
reach the minimum level (red point in the aperture or lower
marking on the oil gauge), consequential damages such as
seizure of bearings, connecting rod, piston pin, crankshaft or
piston seizing must be counted with.
CAUTION:
The air hole of the engine case is located in the oil filler neck
(No. 1 or 3).
Air is commonly slightly blown in this place when the
appliance is operated, which is normal. Excess pressure in
the engine case caused by the movement of pistons, which
results in oil leaking in that place is also normal (to be wiped
occasionally).
The claim arising from the warranty will not apply in case
of consequential damages as a result of the failure to
meet the above-mentioned!!!
Safety instructions for inspections and servicing
Only a regularly serviced and treated appliance may be a
satisfactory aid. Inadequate servicing and maintenance may
lead to unexpected accidents and injuries.
