Maintenance
Lubricating the Cutting
Units
Each cutting unit has 5 grease fittings
must be lubricated regularly with No. 2 lithium grease.
There are 2 lubrication points on the front roller, rear
roller, and 1 at the reel motor spline.
Note:
Lubricating cutting units immediately after
washing helps purge water out of the bearings
and increases bearing life.
1.
Wipe each grease fitting with a clean rag.
2.
Apply grease until clean grease comes out of
the roller seals and the bearing relief valve.
3.
Wipe any excess grease away.

Relief-Grinding the Reel
The new reel has a land width of 1.3 to 1.5 mm (0.050
to 0.060 inch) and a 30 degree relief grind.
When the land width gets larger than 3 mm (0.120
inch) wide, do the following:
1.
Apply a 30 degree relief grind on all reel blades
until the land width is 1.3 mm (0.050 inch) wide
(Figure 23
and
Figure
(Figure
22) that

1. 1.3 mm (0.050 inch)
2.
Spin grind the reel to achieve <0.025 mm (0.001
inch) reel run-out.
Note:
This causes the land width to grow
slightly.
Note:
To extend the longevity of the sharpness of the
edge of the reel and the bedknife—after grinding the
reel and/or the bedknife—check the reel to bedknife
contact again after cutting 2 faiways, as any burrs
will be removed, which may create improper reel to
bedknife clearance and thus accelerate wear.
