REPLACING/REPAIRING
Fuel Filter
WARNING
The fuel system operates under high
pressure. This system should be serviced
by a Walker dealer or authorized Kohler
service dealer.
Model T30i is equipped with a high-volume, high-
pressure, 10-15 micron, in-line fuel filter. Replace-
ment of this filter is recommended
every 1500
hours
of operation or more frequently under ex-
tremely dusty or dirty conditions. Because the
T30i has a pressurized fuel system, fuel filter re-
placement should be done by a Walker dealer or
authorized Kohler service dealer.

Blade Overload Shear Bolts
NOTE:
Blade shear bolts are not used on belt driv-
en decks.
On gear driven decks, each cutting blade is keyed
to the blade hub by
two (2) shear bolts
(10-24 x
5/8 in. stainless steel machine 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 lb·ft (81 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 section for
Sharpen Mower Blades
which de-
scribes the blade removal and installation proce-
dure.
After reinstalling the blade, check blade timing (on
gear driven decks) by moving blades through
one
(1) complete revolution.
Make sure blade tips
pass clear of each other. If timing is incorrect, con-
tact your Walker dealer.
