Fuel Filter
DANGER
Gasoline is extremely flammable and can
be highly explosive. To minimize danger:
●
Before servicing the fuel system:
1) Disconnect the spark plug leads.
2) Disconnect the negative (-) battery
cable from battery.
●
Use only an approved fuel container
for gasoline.
●
DO NOT allow open flames or sparks
near the machine while performing
maintenance or refueling; DO NOT
smoke while working with fuel.
●
Wipe up spilled gasoline immediately
and completely.
Model S14i is equipped with an in-line fuel filter be
tween the fuel tank and the fuel pump (low pressure
fuel pump). Visually inspect the filter periodically,
and replace the filter
yearly
or when contamination
is suspected or found in the fuel.

Fuel Filter and Fuel Shut-Off Valve Location
IMPORTANT:
Replace the fuel filter only in a clean
area where the fuel line and connections will not be
contaminated by dust and dirt.
1. Close the fuel shut-off valve.
2. Expand and slide clamps on either side of the
filter away from filter and pull fuel lines off filter.
3. Replace filter, making sure that the arrow on the
filter is aligned with the fuel flow through the
filter.
4. Verify that the fuel lines and clamps are securely
attached, and that no fuel leaks are present.
5. Open the fuel shut-off valve.
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.
