Boom Swivel Bearings (figure 4.3d):
Grease the
boom bearings once every week with a multi-purpose
moisture resistant #2 grease.

PTO Bearing & PTO Shaft Fitting (figure 4.3e):
The
PTO bearings should be greased after every 50 hours
of operation with a high grade, high temperature lithium
base #2 lubricant having an operating temperature of 200
degrees F. Three to five pumps with a hand operated
grease gun is sufficient.
NOTE:
Units manufactured
after 2000 may not have a PTO bearing grease fitting.
These bearings are sealed and do not require greasing.
The PTO crossover shaft and linkage should be lubricat
-
ed with high temperature lithium base #2 lubricant after
200 hours of operation.
5. Hinge and Friction Points:
Leaf vacuum operation and
longevity can be improved by keeping hinges and friction
points lubricated. It is recommended that lubricaton be
performed weekly. Use SAE30 weight oil on hinges and
a premium grade, high temperature lithium based EP#2
grease on friction points.
6.
Hitch and Tongue (figure 4.3f):
The hitch and hitch ring
should be checked and lubricated daily to minimize wear.
Apply grease and/or SAE30 weight oil wherever appli
