Checking The Tire Pressure; Torque The Wheel Lug Nuts; Starting And Stopping The Engine; Checking The Interlock System - Toro 08703 Operator's Manual

Checking the Tire Pressure

Service Interval: Before each use or daily
Check the tire pressure before operating the machine (Figure
17). The correct air pressure in the front and rear tires are:
•
for Treaded tires 4-6 psi (0.3-0.4 bar)
•
for Smooth tires 8-10 psi (0.5-0.7 bar)

Torque the Wheel Lug Nuts

Service Interval: After the first 8 hours
Every 100 hours
Initially, torque the wheel lugs after the first 8 hours of
operation; thereafter, torque the nuts after every 100 operating
hours. Torque the lugs nuts to 45-55 ft-lb (61-75 N-m).
Starting and Stopping the
Engine
1. Remove your foot from the traction pedal, make sure
that the pedal is in the neutral position, and engage the
parking brake.
2. Push the choke lever forward to the On position (when
starting a cold engine) and the throttle lever to the
Slow position.
Important: When operating the machine in
temperatures less than 32°F (0°C) allow the
machine time to warm up before using. This
prevents damage to the hydrostat and the traction
loop.
3. Insert the key into the ignition switch and rotate it
clockwise to start the engine. Release the key when the
engine starts. Regulate the choke to keep the engine
running smoothly.
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.
4. To stop the engine, move the throttle control to the
Slow position and rotate the ignition key to Off.
Remove the key from the switch to prevent accidental
starting.
5. Close the fuel shutoff valve before storing the machine.
CAUTION
Shut the engine off and wait for all moving
parts to stop before checking for oil leaks,
loose parts, and other malfunctions.

Checking the Interlock System

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.
The purpose of the interlock system is to prevent the engine
from cranking or starting unless the traction pedal is in the
neutral position. Also, the engine should stop if the traction
pedal is moved either forward or reverse without an operator
in the seat.
1. Check the interlock operation in a wide open area free
of debris and bystanders. Stop the engine.
2. Sit on the seat and engage the parking brake.
3. Depress the traction pedal in forward and reverse while
trying to start the engine.
4. If the engine cranks, there may be a malfunction in the
interlock system. Repair it immediately.
5. If the engine does not crank, the system is operating
correctly.
6. With the operator in the seat, traction pedal in neutral
and parking brake on, the engine should start. Lift
off the seat and slowly depress the traction pedal, the
engine should stop in one to three seconds. Correct
problem if not operating properly.
