MAINTENANCE

• BEFORE CARRYING OUT ANY OPERATION, ALWAYS PULL OUT THE
PLUG AND DRAIN THE RECEIVER COMPLETELY (figures 10-11)
• Tighten the tie-bolts of the head at start-up and after the first hour of work
(torque 10 Nm = 1.02 Kgm).
• After loosening any safety screws (fig. 12a), clean the intake filter
according to the type of working environment and at least every 100 hours
(figures 12b-12c). If necessary, replace the filter element (clogging of
the filter reduces compressor performance and an inefficient filter causes
increased wear).
• For lubricated models, replace the oil after the first 100 hours of operation
and every 300 hours subsequently (figures 13a-13b-13c). Remember to
check the oil level at regular intervals.
• Periodically (or after working with the compressor for more than an hour),
drain the condensate that forms inside the receiver (fig. 11) due to the
humidity in the air. This protects the receiver from corrosion and does not
restrict its capacity.
• Spent oil (lubricated models) and condensate MUST BE DISPOSED
OF in accordance with environmental protection regulations and current
legislation.
The compressor must be disposed in conformity with the methods
provided for by local regulations

POSSIBLE FAULTS AND RELATED PERMITTED REMEDIES

FAULT
Leakage of air from the valve of the pressure
switch with the compressor off.
www.abac.ru
Reduction of performance. Frequent start-up.
Low pressure values.
The compressor stops and restarts automatically
after a few minutes.
In the V, 3 HP versions, it is does not start.
After a few attempts to restart, the compressor.
The compressor does not stop and the safety
valve is tripped.
FUNCTION
Cleaning of intake filter and/
or substitution of filtering
element
Change of oil*
Tightening of head tension
rods
Draining tank condensate
* For lubricated models only
CAUSE
Check valve that, due to wear or dirt on the seal,
does not perform its function correctly.
Excessive performance request, check for any
leaks from the couplings and/or pipes. Intake
filter may be clogged.
Tripping of the thermal cutout due to overheating
of the motor.
Tripping of the thermal cutout due to overheating
of the motor (removal of the plug with the
compressor running, low power voltage).
Irregular functioning of the compressor or
breakage of the pressure switch.

REMEDY
Unscrew the hexagonal head of the check valve,
clean the valve seat and the special rubber
disk (replace if worn). Reassemble and tighten
carefully (figures 14a-14b).
Replace the seals of the fitting, clean or replace
the filter.
Clean the air ducts in the conveyor. Ventilate
the work area. Reset the thermal cutout. On
lubricated and V type models, check oil level
and quality. On V models, have the voltage
checked.
Activate the on/off switch. Ventilate the work
area. Wait a few minutes. The compressor will
restart independently. On V, 3 HP models, reset
the thermal cutout. Remove any power cable
extensions.
Remove the plug and contact the Service
Center.
