Starting The Engine; Checking The Safety Interlock System - Toro 04530 Operator's Manual

the machine at mowing speed until the brakes are hot,
as indicated by their smell. An adjustment to the brakes
may be required after break-in; refer to Adjusting the
Brakes.

Starting the Engine

Note: Inspect the area beneath the mowers to be
certain they are clear of debris.
1. Sit on the seat, lock the parking brake, disengage the
raise/lower mow control and move the functional
control lever to Neutral.
2. Remove your foot from the traction pedal and make
sure the pedal is in the Neutral position.
3. Move the choke lever to the closed position (only
when starting a cold engine) and the throttle lever
to the half throttle position.
4. Insert and rotate the ignition key clockwise until
the engine starts. After the engine starts, regulate
the choke to keep the engine running smoothly. As
soon as possible, open the choke by pushing it in
to the Off position. A warm engine requires little
or no choking.
5. Check the machine out with the following
procedures after the engine has started:
A. Move the functional control lever to the Mow
position and release the parking brake. Move
the throttle control to the Fast position and
momentarily engage the reels by moving the
raise/lower mow control lever forward. The
cutting units should drop and all the reels should
turn.
B. Move the raise/lower mow control lever
rearward. The cutting reels should stop and the
cutting units should raise to the full transport
position.
C. Set the brake to keep the machine from moving,
and operate the traction pedal through the
forward and reverse positions.
D. Continue the above procedure for 1-2 minutes.
Neutralize the functional control lever, lock the
parking brake, and turn the engine off.
E. Check for oil leaks. If oil leaks appear, check
the tightness of the hydraulic fittings. If oil
leaks continue to appear, contact your local
Toro Distributor for assistance and, if necessary,
replacement parts.
Important: A trace of oil on the motor or
wheel seals is normal. Seals require a small
amount of lubrication to perform properly.
Note: When the machine is new and the
bearings and reels are tight, it is necessary to use
the Fast throttle control position for this check.
A fast throttle setting may not be required after
the break-in period.
Checking the Safety Interlock
System
CAUTION
If the 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 safety interlock system is to prevent
operation of the machine where there is possible injury
to the operator or the machine.
The safety interlock system prevents the engine from
starting unless:
• The traction pedal is in neutral.
• The functional control lever is in neutral.
The safety interlock system prevents the machine from
moving unless:
• The parking brake is off.
• The operator is seated.
• The functional control lever is in Mow or Transport.
The safety interlock system prevents the reels from
operating unless the functional control lever is in the
Mow position.
Perform the following system checks daily to be sure
the interlock system is operating correctly:
1. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral, and
engage the parking brake. Try to depress the
traction pedal. The pedal should not depress,
which means that the interlock system is operating
correctly. Correct the problem if it is not operating
properly.
2. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral, and
engage the parking brake. Move the functional
control lever to mow or transport and try to start the
engine. The engine should not crank, which means
