1. Reach into the frame opening, indicated in Figure 7-4,
and pull the fuel shut-off valve and pre-filter from their
stored position in the frame.
2. Close the shut-off valve. Remove the two clamps
securing the pre-filter to the fuel hose. Remove the
pre-filter.
3. Install a new pre-filter. Be sure it is installed in the
proper direction as shown in Figure 7-4. Secure to the
fuel hose using the two clamps.
4. Thoroughly clean the outside of the filter housing. Dirt
must not be allowed to enter the fuel or the fuel injection
system.
5. Unscrew the fuel filter cartridge from the housing.
6. Apply a thin layer of fuel oil over the gasket of the new
cartridge and hand tighten the cartridge.
7. Bleed the air from the fuel system.
C. Fuel System Bleeding
Bleeding the fuel system is necessary after the fuel filter
and lines have been removed, after the fuel tank has become
empty, and after long storage of the mower.
Air Vent
WARNING:
To avoid personal injury do not bleed a hot
engine. The bleeding procedure could cause
fuel to spill onto a hot exhaust manifold
creating a danger of fire.
1. Fill the fuel tank per instructionsinsection 7.5, filling the
fuel tank. Be sure the fuel shut-off valve is open.
2. Open the air vent on top of the fuel injection pump
(Figure 7-5).
Figure 7-5 Fuel Injection Pump
-IMPORTANT-
Always keep the air vent plug on top of the
fuel injection pump closed except when bleed-
ing air from the system.
3. Turn the ignition key to the ON position and allow the
fuel pump to run for about one minute to purge the air.
4. Close the air vent valve on the fuel injection pump.
7.6 ENGINE COOLANT SYSTEM
A. Checking Coolant Level
Hot coolant can scald. Check and service the
cooling system only when cool.
Before each day of operation the coolant level should be
checked. Visually check the overflow bottle. Coolant should
be to the full mark on the overflow bottle. See Figure 7-6.
If coolant is within the range between “FULL “ and “LOW”,
the coolant will last for one day’s work. If the coolant is
low, add a mixture of water and anti-freeze to the overflow
bottle or the radiator. IF THE ENGINE IS HOT, DO
NOT remove the radiator cap. The system is under pressure
and the coolant can cause severe burns or eye injury. When
it is necessary to remove the radiator cap, wear protective
clothing and safety glasses. Always turn the cap slowly to
the first stop, and allow the pressure to escape before
removing the cap completely.
