6.10 Fan
Check the fan for cracking, loose rivets, and bent or loose blades. Make sure that it is
securely mounted and tighten the mounting screws if loose. Replace a damaged fan
immediately.
6.11 Motor
The motors on the air compressor require routine attention too. Every 1000 hours of
operation or six months, whichever comes first, check that the motor is clean and
ventilation openings are clear.
The second area to maintain to insure long motor life is bearing lubrication. Bearing
grease will lose its lubricating ability over time, not suddenly. The type of grease used,
the temperature of operation, and the speed of the motor effect the life of the bearing
lubrication. You should re-grease the bearings every 2000 hrs or once a year. Units in
severe duty (dusty locations or high ambient temperatures) the time interval is 1000
hours.
A high quality ball or roller bearing grease with the following characteristics should be
used:
