SERVICE INSTRUCTIONS
Fuel Filter - Model MB, MC, MT, MT25
Models MT, MTL, MC and MB are equipped with an in-
line fuel filter. Visually inspect the filter periodically, and
replace the filter yearly.
Fuel Filter Location
IMPORTANT: Replace the fuel filter only in a clean ar-
ea where the fuel line and connections will not be con-
taminated by any dust and dirt.
1. Expand and slide clamps on either side of the filter
away from filter and pull fuel lines off filter.
2. Replace filter.
Fuel Filter - Model MTEFI, MTLEFI
EFI engines use a high-volume, high-pressure, 10-15
micron, in-line fuel filter.
In-Line Fuel Filter
Service
Fuel filter replacement is recommended every 1500
hours of operation or more frequently under extremely
dusty or dirty conditions. Use only the specified filter,
and install it according to the directional arrows. DO
NOT use a substitute filter as operating performance
and safety can be affected. Relieve system pressure
through the safety valve in the fuel rail before servicing.
General
High-pressure fuel line with an SAE R9 rating is re-
quired for safe and reliable operation, due to the higher
operating pressure of the EFI system. If hose replace-
ment is necessary, order by part number or use only the
type specified. Special Oetiker clamps (Kohler Part No.
24 237 05-S or Walker P/N 5879-5) are used on all fuel
line connections to prevent tampering and safety haz-
ards with the high fuel pressure. The old clamp must be
cut to open a connection, so replacement is necessary
each time. Pliers (SPX Part No. KO3217-5) is used to
crimp the replacement clamps.
DANGER
Gasoline is extremely flammable and can
be highly explosive. To minimize danger:
• Use only an approved fuel container for
gasoline.
• DO NOT allow open flames or sparks
near the machine while performing main-
tenance or refueling; DO NOT smoke
while working with fuel.
• Wipe up spilled gasoline immediately
and completely.
