Greasing the Bearings,
Bushings, and Gear Box
The cutting unit must be lubricated regularly. If the
machine is operated under normal conditions, lubricate the
castor bearings and bushings with No. 2 general purpose
lithium base grease or molybdenum base grease, after every
8 hours of operation or daily, whichever comes first. All
other bearings, bushings and the gear box must be
lubricated after every 50 hours of operation.
1. The cutting unit has bearings and bushings that must be
lubricated. Lubricate the following areas:
caster spindle bushings (Fig. 21 and 22)
caster wheel bearings (Fig. 22 and 23)
blade spindle bearings (Fig. 24)
right and left push arm ball joints (Fig. 24)
2. Position the machine and cutting unit on a level surface
and lower the cutting unit. Remove the dipstick/fill plug
from the top of the gear box (Fig. 25) and make sure
that the lubricant is between the marks on the dipstick.
If the lubricant level is low, add SAE 80–90 wt. gear
lube until the level is between the marks.
