6- THE BELTS ARE LOOSE.
CHECK THE TENSION OF BELTS. IT IS EASY TO UNDERSTAND THAT THE BELTS IS LOOSE BY LOOKING
AT THE MOVEMENT OF BELT WHEN THE COMPRESSOR IS RUNNING. PROPERLY ADJUSTED BELTS ARE
NOT BEATS. STRAIN THE BELTS BY CHECKING ITEMS AT "BELT REPLACEMENT AND ALIGNMENT"
SECTION OR INFORM THE SERVICE.
ALSO BELTS MAY BE OILY. IN THIS CASE WHEN THE PRESSURE INCREASES, THE OILY BELTS MAY BE
SLIP. HIGHLY NOISE IS HEARD AND SMOKE IS OBSERVED. CLEAN THE PULLEYS AND REPLACE THE
BELTS
7- THERE IS A MECHANICAL PROBLEM AT COMPRESSOR UNIT
IT COULD BE UNDERSTOOD BY NOISY OPERATION. INFORM THE SERVICE.
12-
THE OIL LOOSES ITS CHARACTERISTICS AND THE SEPARATOR GETS BLOCKED RAPIDLY
1- THE RECOMMENDED OIL OR ORIGINAL SEPARATOR IS NOT BEING USED.
2- AMBIENT HUMIDITY IS TOO HIGH
3- THERE IS DUST, GAS ETC. IN THE ENVIRONMENT THAT IMPAIR THE PROPERTY OF OIL.
THIS POINT MUST IS TAKEN INTO CONSIDERATION WHEN DETERMINING THE COMPRESSOR ROOM IN
SANDBLASTING CASTING CHEMICAL AND PAINT / CHEMICAL FINISHING FACILITIES.
4- CONTINUOUSLY OPERATING IN HIGH AMBIENT TEMPERATURE
AT THE COMPRESSORS THAT OPERATE NEAR THE BOILER ROOMS, GENERATOR ROOM OR AT AREAS
WITH INSUFFICIENT VENTILATION, THE OPERATING TEMPERATURE ADVERSELY AFFECTS THE LIFE OF

SECONDS (ACCORDING TO COMPRESSOR TYPE). DO NOT ADJUST IT FOR SHORTER PERIOD. REPLACE
YOUR OLD CONTACTS WITH NEW ONES.
3- THE COMPRESSOR EXCESSIVELY STARTS AND STOPS
THE SUGGESTED MAXIMUM NUMBER OF START IN 1 HOUR IS 6. MORE RAPIDLY STARTING AND
STOPPING AFFECTS ADVERSELY THE MECHANICAL LIFE AND DUE TO THE EXCESSIVE CURRENT
DRAW AT START UP THE OPERATIONAL COST INCREASES. FOR DETAILED INFORMATION, CONTACT
THE SERVICE.
