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:
1. Clear the area of bystanders, especially small
children.
2. Place all controls in neutral, stop engine and
remove ignition key or disconnect PTO
driveline before starting.
3. Unlatch and remove the belt drive covers.
4. Checking Oil Level:
a. Remove the level plug in each reservoir or
check the sight glass.
IMPORTANT
Check the level only when the oil is cold
and the machine is level.
b. Oil in the reservoir should just fill the
threads of the level plug hole.
c. Add oil if low or allow the reservoir to drain
if overfilled.
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.
d. Install and tighten the level plug.
e. Install and secure the belt covers.
