DANGER
Gasoline is flammable. Use caution when storing
or handling it. Do not smoke while filling the fuel
tank. Do not fill fuel tank while engine is running
or in an enclosed area. Always fill fuel tank out-
side and wipe up any spilled fuel before starting
the engine. Store fuel in a clean, safety--ap-
proved container and keep the cap in place. Use
gasoline for the engine only; not for any other
purpose.
2. Access the carbon cannister under the fuel tank and
between the rear frame sections. If necessary, raise and
support tank mount plate assembly (hydraulic reservoir,
fuel tank and tank mount plate) to reach the cannister
(see Tank Mount Plate Assembly in the Service and Re-
pairs section of Chapter 7 -- Chassis).
3. Inspect carbon cannister for damage or obvious
leaks. A damaged or leaking cannister should be re-
placed.
4. Remove components as needed using Figure 3 as
a guide.
A. If check valve (item 15) is removed, note direction
of arrow on valve body for assembly purposes.
Installation (Fig. 3)
1. Install all removed components using Figure 3 as a
guide.
A. If check valve (item 15) was removed, make sure
that arrow on valve body points toward engine.
B. Make sure that fuel hoses are not kinked after
installation. Also, secure all hoses with hose clamps.
2. If tank mount plate assembly (hydraulic reservoir,
fuel tank and tank mount plate) was raised to access the
cannister, lower and secure tank mount plate assembly
(see Tank Mount Plate Assembly in the Service and Re-
pairs section of Chapter 7 -- Chassis).
