Compressor’s oil consumption
rising
Too much oil in compressor
Check oil level 2 or 3 minutes after stopping
Leaks around crank case
Contact Adendorff Machinery
Working temperature of compressor too high
because of insufficient cooling
Increase ventilation to air compressor
Unit to small in proportion to air consumption Connect supplementary
Cylinder worn
Contact Adendorff Machinery
Intake air filter blocked
Clean;/replace air filter
Compressor runs continuously
and cannot attain the working
pressure required
Suction filter blocked
Change filter
V-belt too slack (not applicable to direct drive
machines)
Tighten V-Belt
Leak between compressor block and air
receiver/leaks in or near air receiver
Tighten connection and repair leak or contact
Adendorff Machinery
RPM too low because of incorrectly con-
nected electric motor
Contact Adendorff Machinery
Valves blocked by dirt, paint, dust or clogged up Contact Adendorff Machinery
Inspection cover or plug leaking
Empty air receiver and change seal or contact
Adendorff Machinery
Suction rendered difficult or impossible at
suction intake or the air being taken in is too
warm
Ensure unobstructed air flow around the unit
Pressure gauge defective
Unit to small in relation to air consumption of
connected equipment
Install a larger compressor
Compressor worn
Have compressor overhauled or replace it
Compressor becomes too hot
Insufficient ventilation
See that sufficient air is supplied to flywheel or fan
of compressor and that hot air is properly vented
Oil level too low (check 2 or 3 times after
stopping
Fill with oil –Adendorff synthetic compressor oil.
See – page #6
Fault in valves (machine not stopping)
Contact Adendorff Machinery
Blown head gasket (machine not stopping
Contact Adendorff Machinery
Dirt on cooling fins or suction filter
Clean cooling fins and suction filter
Unit working at too high a pressure
Contact Adendorff Machinery
Non-return valve partly blocked
Clean or thaw out non-return valve
Compressor being overworked and running
continuously
Use a larger compressor
Oil in the air delivered
Sump over full
Reduce oil to correct level
Cylinder worn
Contact Adendorff Machinery
Intake air filter blocked
Change air filter
Condensation in crank case
(especially in 2-stage compres-
sors)
Compressor over dimensioned (operational
periods to short in relation to resting periods)
Frequent oil changes
Reduce cooling of crank case (e.g. by shielding it
from the air stream)
Contact Adendorff Machinery
Condensation at outlet points
Piping installation is incorrect
Contact your local Adendorff
Compressor is taking in air that is too warm
Obtain better fresh air supply for the compressor
Delivery temperature of air from air receiver
is too high
Use a large air receiver
