Checking The Safety Interlock System - Toro 04510 Greensmaster 3300 TriFlex Operator's Manual

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 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 that the
interlock system is operating correctly. Correct the
problem if it is not operating properly.
3. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral, and
engage the parking brake. Start the engine and move
the functional control lever to mow or transport. The
engine should kill, which means that the interlock
system is operating correctly. Correct the problem if it
is not operating properly.
4. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral, and
engage the parking brake. Start the engine. Release
the parking brake, move the functional control lever
to mow, and rise from the seat. The engine should
kill, which means that the interlock system is operating
correctly. Correct the problem if it is not operating
properly.
5. Sit on the seat, move the traction pedal to Neutral,
move the functional control lever to Neutral, and
engage the parking brake. Start the engine. Move the
raise/lower mow control forward to lower the cutting
units. The cutting units should not start rotating. If
they do, the interlock system is not operating correctly.
Correct the problem.
