occurred and the clutch must be disassembled to
separate the friction discs, see "Clutch Assembly
and Disassembly", on page 16.
5. Tighten each of the 8 spring retainer nuts on the clutch
housing EXACTLY 2 revolutions to restore the original
clutch setting pressure.
6. The clutch should be checked during the first hour of
cutting and periodically each week. An additional set
of scribe marks can be added to check for slippage.
See "Clutch Assembly and Disassembly", on
page 16, to adjust for proper spring length.
Clutch Assembly and Disassembly
If the clutch run-in procedure, (see "Clutch Run-In"on
page 15), indicated that one or more of the friction discs did
not slip, the clutch must be disassembled to separate the
friction discs. Refer to the Parts Section of this manual for a
detailed parts breakdown.
Refer to Figure 4-2:
To disassemble the clutch, first remove the spring retainer
nuts (#8), springs (#1) and bolts (#3) from the assembly.
Each friction disc (#4) must then be separated from the
metal surface adjacent to it. Inspect all parts for excessive
wear and condition. Clean all parts that do not require
replacement.
The original friction disc thickness is 1/8" (3.2mm) and
should be replaced if the thickness falls below 3/64"
(1.1mm). If the clutches have been slipped to the point of
"smoking", the friction discs may be damaged and should
be replaced. Heat build-up may also affect the yoke joints.
Install new friction discs if needed and reassemble all
components in proper order. Progressively tighten each
spring retainer bolt until the spring length is 1.010 inches.

Storage
At the end of the working season or when the cutter will not
be used for a long period, it is good practice to clean off
any dirt or grease that may have accumulated on the
cutter and any of the moving parts.
1. Clean the cutter as necessary.
2. Check the blades for wear and replace if necessary,
see "Service Cutting Blades", page 15.
3. Inspect the cutter for loose, damaged or worn parts
and adjust or replace as needed.
4. Lubricate as noted in "Lubrication" starting on
page 17
5. Store the cutter inside if possible for longer cutter life.
6. Repaint parts where paint is worn or scratched to
prevent rust. Ask your dealer for Aerosol Land Pride
Beige touch-up paint part #821-011C.
