CHAIN SHIELDING
Full chain shielding must be installed when
operating in populated areas or other areas where
thrown objects could injure people or damage
property.
If this machine is not equipped with full chain
shielding, operation must be stopped when any-
one comes within 300 feet (92 m).
This shielding is designed to reduce the risk
of thrown objects. The mower deck and protec-
tive devices cannot prevent all objects from
escaping the blade enclosure in every mowing
condition.
It is possible for objects to ricochet
and escape, traveling as much as 300 feet (92 m).
Check that chain shielding is in good condition and
replace any damaged chain links.
CLEANING
After Each Use
Remove large debris such as clumps of dirt, grass,
crop residue, etc. from machine.
Inspect machine and replace worn or damaged
parts.
Replace any safety decals that are missing or not
readable.
Periodically or Before Extended Storage
Clean large debris such as clumps of dirt, grass,
crop residue, etc. from machine.
Remove the remainder using a low-pressure water
spray.
1. Be careful when spraying near scratched or torn
safety decals or near edges of decals as water
spray can peel decal off surface.
2. Be careful when spraying near chipped or
scratched paint as water spray can lift paint.
3. If a pressure washer is used, follow the advice
of the pressure washer manufacturer.
Inspect machine and replace worn or damaged
parts.
Sand down scratches and the edges of areas of
missing paint and coat with spray paint of matching
color (purchase from your dealer).
Replace any safety decals that are missing or not
readable (supplied free by your dealer). See Safety
Decals section for location drawing.
