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 lter. Replace-
ment of this lter 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 lter 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.

Cutting Blade Shear Bolts
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.
