Fuel System

Avoid serious injury or death from gasoline fire or explosion. Carefully follow all fuel system service
instructions. Always stop the engine and do not smoke or allow open flames or sparks in the area
while servicing any part of the fuel system.
Before servicing any part of the fuel system, stop engine and disconnect the battery. Drain the fuel system
completely. Use an approved container to collect and store fuel. Wipe up any spillage immediately.
Material used to contain spillage must be disposed of in an approved receptacle. Any fuel system service
must be performed in a well ventilated area. Inspect any completed service work for sign of fuel leakage.
FUEL LINE INSPECTION
Visually inspect the fuel line and primer bulb for cracks, swelling, leaks, hardness, or other signs of
deterioration or damage. If any of these conditions are found, the fuel line or primer bulb must be
replaced.
WATER SEPARATING FUEL FILTER
NOTE: The warning system will turn on when water in the fuel filter reaches the full level. See Features
& Controls - Warning System.
The water separating fuel filter removes moisture and also debris from the fuel. If the filter becomes filled
with water, the water can be removed. If the filter becomes plugged with debris, the filter must be replaced
with a new filter.
1. Remove and replace filter as follows:
a. Turn ignition key switch to "OFF" position.
b. Disconnect wire at bottom of filter.
c. Remove filter by turning the filter clockwise. Tip the filter to drain fluid in a suitable container.
d. Lubricate the sealing ring on the filter with oil. Thread on the filter and tighten securely by
hand. Reconnect the wire to the filter.
IMPORTANT: Visually inspect for fuel leakage from the filter by squeezing the primer bulb until firm,
forcing fuel into the filter.

Steering Link Rod Fasteners

IMPORTANT: The steering link rod that connects the steering cable to the engine must be fastened
using special washer head bolt ("a" - Part Number 10-849838) and self-locking nylon insert locknuts ("c"
& "d" - Part Number 11-826709113). These locknuts must never be replaced with common nuts (non-
locking) as they will work loose and vibrate off freeing the link rod to disengage.
