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

Only 8 hours of mowing operation is required for the break-in
period.
Since the first hours of operation are critical to future
dependability of the machine, monitor its functions and
performance closely so that minor difficulties, which could
lead to major problems, are noted and can be corrected.
Inspect the machine frequently during break-in for signs of
oil leakage, loose fasteners, or any other malfunction.
To ensure optimum performance of the brake system, burnish
(break-in) the brakes before using the machine. To burnish
the brakes, firmly apply the brakes and drive 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
