5.0 MAINTENANCE
IT IS IMPERATIVE THAT ALL PERSONS USING, OPERATING OR MAIN-
TAINING THIS COMPRESSOR AFTERCOOLER BE FULLY TRAINED AND
COMPETENT AND AUTHORIZED TO DO SO AND HAVE READ THE EN-
TIRE OPERATING MANUAL.
IT IS RECOMMENDED THAT THIS COMPRESSOR AFTERCOOLER IS
SERVICED EVERY 12 MONTHS, REGARDLESS OF ITS CONDITION OR
THE NUMBER OF OPERATING HOURS USED. THIS WILL HELP TO EN-
SURE RELIABLE, TROUBLE FREE SERVICE.
GMP, CANNOT BE HELD RESPONSIBLE FOR MISUSE OF THIS EQUIP-
MENT.
5.1 PRE-USAGE CHECKS
● Check that the oil reservoir on the air motor lubricator is full of a high quality
air tool lubrication oil.
● Check that the drain bowls on both the air motor filter/regulator and the after-
cooler separator are emptying correctly.
● Check that the aftercooler grill is free from dirt and leaves, if necessary blow
the debris outwards with a low pressure airline, (Max. 2 Bar 30 P.S.I.). Note,
this should be undertaken with due consideration to personnel safety. Correct
cooling depends upon an uninterrupted flow of air through the finned tubes of
the cooler. If the spaces between the fins are allowed to become clogged with
dirt, the performance of the aftercooler will deteriorate.
● Check that the cam and groove air hose coupling faces are clean and free
from debris.
● Check the tire pressure, adjust if necessary.
● Check that all screws are tight, especially the fan mounting bracket and
guard.
● Check for air leakage, rectify before commencing.
5.2 WEEKLY MAINTENANCE
●
Carry out all the Pre-usage checks as per 5.1
● Open the manual discharge valve on the Condensate Separator (screw care-
fully) and let water flow out air until the compressed air will blow through for a
few seconds (into a suitable container for environmentally friendly disposal). If
a significant amount of water (more than 0.5 liters) exits the valve then the
drain must be thoroughly cleaned.
