5.2.2 BLOWER OIL CHANGING AND BREATHER CLEANING
The gears that drive and time the blower lobes run in an oil bath for lubrication. Maintaining the correct level in the reservoirs and changing every 100 hours will insure proper lubrication.
When maintaining the blower, follow this procedure:
Checking Oil Level:
IMPORTANT :Check the level only when the oil is cold and the machine is level.
IMPORTANT : It is necessary to maintain the recommended oil level in the reservoir. A low level causes heating from lack of lubrication and rapid gear and bearing wear. Too much oil causes heating from oil churning and can cause seal and breather leaks.

IMPORTANT : Condensation forms and collects inside the reservoirs during machine operation. Changing oil removes this water and prevents it from damaging the gears and bearings
