Maintenance
Note:
Determine the left and right sides of the machine
from the normal operating position.
Lubrication
Each cutting unit has (7) grease fittings (Fig. 8) that must
be lubricated regularly with No. 2 General Purpose Lithium
Base Grease.
The lubrication points are front roller (2), rear roller (2),
reel bearing (2) and bedknife adjuster.
Important
Lubricating cutting units immediately after
washing helps purge water out of bearings and increases
bearing life.
1.
Wipe each grease fitting with a clean rag.
2.
Apply grease until clean grease is seen coming out of
roller seals and bearing relief valve.
3.
Wipe excess grease away.

Adjusting the Reel Bearings
To insure long life of the reel bearings, periodically check if
reel end play exits. The reel bearings can be checked and
adjusted as follows:
1.
Hold on to the reel shaft and try to move the reel
assembly side to side (Fig. 9).

2.
If end play exists, proceeded as follows:
A. Loosen external set screw securing bearing
adjusting nut to bearing housing located on the left
side of the cutting unit (Fig. 10).

B. Using a 1–3/8” socket wrench, slowly tighten the
reel bearing adjustment nut until no end play of the
reel exists. If adjusting nut does not eliminate reel
end play, replace reel bearings.
Note:
Reel bearings
do not
require pre–load. Over
tightening reel bearing adjuster nut will
damage reel bearings.
3.
Retighten set screw securing bearing adjusting nut to
bearing housing. Torque set screw to 12–15 in–lbs.
