Bleeding The Fuel System; Checking The Interlock System - Toro 30807 Operator's Manual

Turn the steering wheel to the left and right to check
steering response; then shut the engine off and check
for oil leaks, loose parts, and any other noticeable
malfunctions.
CAUTION
Stop the engine and wait for all moving parts
to stop before checking for oil leaks, loose
parts, and other malfunctions.
Stopping the Engine
Move the throttle control to the Idle position, move the
cutting unit drive switch to Disengage, and rotate the starter
key to Off. Remove the key from the switch to prevent
accidental starting.

Bleeding the Fuel System

1. Park the machine on a level surface. Make sure that the
fuel tank is at least half full.
2. Unlatch and raise the hood.
DANGER
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A
fire or explosion from fuel can burn you and
others and can cause property damage.
• Use a funnel and fill the fuel tank outdoors,
in an open area, when the engine is off and
is cold. Wipe up any fuel that spills.
• Do not fill the fuel tank completely full.
Add fuel to the fuel tank until the level is
6 to 13 mm (1/4 to 1/2 inch) below the
bottom of the filler neck. This empty space
in the tank allows the fuel to expand.
• Never smoke when handling fuel, and stay
away from an open flame or where fuel
fumes may be ignited by a spark.
• Store fuel in a clean, safety-approved
container and keep the cap in place.
3. Open the air bleed screw on the fuel injection pump
(Figure 31).
1. Fuel injection pump bleed screw
4. Turn the key in the ignition switch to the On position.
The electric fuel pump will begin operation, thereby
forcing air out around the air bleed screw. Leave the
key in the On position until a solid stream of fuel flows
out around the screw.
5. Tighten the screw and turn the key to Off.
Note: Normally the engine should start after the above
bleeding procedures are followed. However, if the engine
does not start, air may be trapped between the injection pump
and injectors; refer to Bleeding Air from the Injectors.

Checking the Interlock System

Service Interval: Before each use or daily
CAUTION
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
1. Make sure that all bystanders are away from the area of
operation. Keep hands and feet away from the cutting
units.
2. While sitting on the seat, the engine must not start
with either the cutting unit switch engaged or the
traction pedal engaged. Correct the problem if it is not
operating properly.
3. While sitting on the seat, put the traction pedal in
neutral, the parking brake off, and the cutting unit
switch in the Off position. The engine should start.
Rise from the seat and slowly press the traction pedal,
the engine should stop in one to three seconds. Correct
problem if it is not operating properly.
