Fuel Filter
Model MC is equipped with an in-line fuel filter. Vi-
sually inspect the filter periodically, and replace the
filter yearly.
Fuel Filter Location
IMPORTANT: Replace the fuel filter only in a clean
area where the fuel line and connections will not be
contaminated 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.
Blade Overload Shear Bolts
The cutting blade is keyed to the blade hub by two
(2) shear bolts (10-24 x 5/8 in. stainless steel ma-
chine screws). These bolts are designed to shear
and protect the blade drive gearbox from damage if
the blade encounters a shock load.
Cutting Blade Shear Bolts
NOTE: Tightening the 5/8-18 blade mounting nut
to 60 ft-lb (81.3 N
⋅m) is also important for proper
shock load protection. It is important to not over-
tighten the mounting nut since this defeats (over-
rides) the function of the shear bolts.
If these bolts shear, remove the blade and install new
bolts. Refer to CHECKING/SERVICING in this sec-
tion for Sharpen Mower Blades which describes the
blade removal and installation procedure.
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.
