DANGER
Gasoline is extremely ammable 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 ames 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 lter be-
tween the fuel tank and the fuel pump (low pressure
fuel pump). Visually inspect the lter periodically,
and replace the lter yearly or when contamination
is suspected or found in the fuel.

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