Maintenance Instructions

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.
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.

REPLACING/REPAIRING

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.

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.
