Break-in Period

Refer to the Engine Manual supplied with the machine for
oil change and maintenance procedures recommended
during the break-in period.
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,
page 34.

Starting the Engine

Note: Inspect the areas 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 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 pulling it rearward 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 throttle control to the Fast position and
momentarily engage the reels by moving the
1
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.
Important
basket to be sure it is not in contact with the reel during
operation. Adjust the pull arms if contact is noted; refer
to Installing the Cutting Units.
C. Depress the brake pedal 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
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.
Testing the Safety Interlock
System
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.
• Replace switches every two years regardless of
whether they are operating properly or not.
