Starting And Stopping The Engine; Bleeding The Fuel System - Toro 03422 Operator's Manual

Starting and Stopping the
Engine
Important
The fuel system may have to be bled if any
of the following situations have occurred:
Initial start up of a new engine.
Engine has ceased running due to lack of fuel.
Maintenance has been performed upon fuel system
components; i.e. filter replaced, etc.
Refer to Bleeding the Fuel System, page 27.
1. Be sure that the parking brake is set and the reel drive
switch is in the DISENGAGE position.
2. Remove your foot from the traction pedal and make
sure that the pedal is in the neutral position.
3. Move the throttle lever to the full throttle position.
4. Remove the cover from the starter switch. Insert the key
into the switch and rotate it counterclockwise (GLOW
PLUG position). Hold it for approximately 20 to 30
seconds, then rotate the key clockwise (START
position) to engage the starter motor. Release the key
when the engine starts. The key will move
automatically to the ON/RUN position.
Important
To prevent overheating of the starter motor,
do not engage the starter longer than 10 seconds. After 10
seconds of continuous cranking, wait 60 seconds before
engaging the starter motor again.
5. For cold weather starting, press the cold start button
to de-clutch the electric traction pump. When the engine
starts, release the button.
6. When the engine is started for the first time, or after
overhauling the engine, operate the machine in forward
and reverse for one to two minutes. Also operate the lift
lever and reel drive switch to be sure of proper
operation of all parts.
Turn the steering wheel to the left and right to check the
steering response. Then shut the engine off and check
for oil leaks, loose parts, and any other noticeable
malfunctions.
Caution
Shut the engine off and wait for all moving parts to
stop before checking for oil leaks, loose parts, and
other malfunctions.
7. To stop the engine, move the throttle control downward
to the IDLE position, move the reel drive switch to
DISENGAGE, and rotate the ignition key to OFF.
Remove the key from the switch and install the switch
cover to prevent accidental starting.
8. Close the fuel shut-off valves before storing the
machine.

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 1 in. (25 mm)
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 fuel shut-off valve under the fuel tank and on
the fuel filter (Fig. 35).
4. Open the 2 bleed screws on the side of the fuel filter
mounting head (Fig. 35), allowing the bowl to fill with
fuel. Close the bleed screws when the bowl is filled.
