Pre-Starting Checks; Starting The Engine; Bleeding The Fuel System - Toro 41581 Operator's Manual

Pre-Starting Checks

Check the following items each time you begin using the
sprayer for the day:
• Check the tire pressure.
Note: These tires are different than car tires; they
require less pressure to minimize turf compaction and
damage.
• Check all fluid levels and add the appropriate amount of
specified fluids, if any are found to be low.
• Check the brake pedal operation.
• Ensure that the lights are working.
• With the engine off, check for oil leaks, loose parts, and
any noticeable malfunctions.
If any of the above items are not correct, notify your
mechanic or check with your supervisor before taking the
sprayer out for the day. Your supervisor may want you to
check other items on a daily basis, so ask what your
responsibilities are.

Starting the Engine

1. Sit on the operator's seat and keep your foot off the
traction pedal.
2. Ensure that the parking brake is engaged, the traction
pedal is in the Neutral position, the throttle is in the
Slow position.
3. Turn the ignition switch to the On/Preheat position.
Note: An automatic timer will control the preheat for
approximately 6 seconds.
4. After preheating, turn the key to the Start position.
5. Crank the engine for no longer than 15 seconds.
6. Release the key when the engine starts.
7. If the engine requires additional preheating, turn the key
to the Off position, then to the On/Preheat position.
Note: Repeat steps 3 through 7 as required.
8. Run the engine at idle speed or partial throttle until the
engine warms up.

Bleeding the Fuel System

1. Park the machine on a level surface.
2. Ensure that the fuel tank is at least half full.
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 inch (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, approved fuel container
and keep the cap in place.
3. Open the vent plug on the fuel/water separator
(Fig. 14).
