Front Cutting Unit Setup
Rotate blade on each spindle until the ends face
forward and backward. Measure from the floor to the
front tip of the cutting edge. Adjust 3 mm (1/8 inch)
shims on front castor fork(s) to match height of cut to
decal (Figure 30); refer to Adjusting the Cutting Unit
Pitch.

Side Cutting Unit Setup
Rotate blade of each spindle until the ends face
forward and backward. Measure from the floor to the
front tip of the cutting edge. Adjust 3 mm (1/8 inch)
shims on front castor arm(s) to match height of cut to
decal (Figure 31). For the outside blade spindle only,
refer to Adjusting the Cutting Unit Pitch.

Matching Height Of Cut Between Cutting Units
1. Position blade side to side on outside spindle
of both side cutting units. Measure from the
floor to the tip of the cutting edge on both
units and compare. These numbers should be
within 3 mm (1/8 inch) of each other. Make no
adjustment at this time.
2. Position blade side to side on inside spindle
of side cutting unit and corresponding outside
spindle of front cutting unit. Measure from the
floor to the tip of the cutting edge on inside edge
of side cutting unit to corresponding outside
edge of front cutting unit and compare. The side
cutting unit measurement should be within 3 mm
(1/8 inch) of the front cutting unit.
Note:
All three cutting units castor
wheels should remain on the ground with
counterbalance applied.
Note:
If adjustments need to be made to match
the cut between the front and side cutting units,
make the adjustments to the side cutting units
g008866
only.
3. If the inside edge of the side cutting unit is too
high relative to the outside edge of the front
cutting unit, remove one 3 mm (1/8 inch) shim
from the bottom of the front inside castor arm
on the side cutting unit
measurement between outside edges of both
side cutting units and inside edge of side cutting
unit to outside edge of front cutting unit.
4. If inside edge is still too high, remove an
additional 3 mm (1/8 inch) shim from bottom of
front inside castor arm of the side cutting unit
and one 3 mm (1/8 inch) shim from the front
outside castor arm of the side cutting unit.
5. If the inside edge of the side cutting unit is too
low relative to the outside edge of the front
cutting unit, add one 3 mm (1/8 inch) shim to
the bottom of the front inside castor arm on the
side cutting unit. Check measurement between
outside edges of both side cutting units and
inside edge of side cutting unit to outside edge
of front cutting unit.
6. If inside edge is still too low, add an additional 3
mm (1/8 inch) shim to the bottom of front inside
castor arm of the side cutting unit and add one
3 mm (1/8 inch) shim to the front outside castor
arm of the side cutting unit.

7. Once cutting height matches at the edges of
front and side cutting units, verify that side
cutting unit pitch is still 8 to 11 mm (5/16 to 7/16
inch). Adjust as necessary.
