Important:
Make sure that the fuel shutoff valve is
closed before transporting or storing the machine, as
fuel leakage may occur. Set the parking brake before
transporting. Make sure to remove the key as the fuel
pump may run and cause the battery to lose charge.
Using the Safety-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.
Understanding the Safety-Interlock
System
The safety-interlock system is designed to prevent the engine
from starting unless:
•
The parking brake is engaged.
•
The blade-control switch (PTO) is disengaged.
•
The motion-control levers are in the N
EUTRAL
-
LOCK
position.
The safety-interlock system also is designed to shut off the
engine when you move the traction controls from the locked
position with the parking brake engaged or if you rise from
the seat when the PTO is engaged.
The hour meter has symbols to notify the user when the
interlock component is in the correct position. When the
component is in the correct position, a triangle lights up in
the corresponding square.

Testing the Safety-Interlock System
Service Interval:
Before each use or daily
Test the safety-interlock system before you use the machine
each time. If the safety system does not operate as described
below, have an Authorized Service Dealer repair the safety
system immediately.
1.
Sitting on the seat, engage the parking brake and move
the blade-control switch (PTO) to the O
N
position.
Try starting the engine; the engine should not crank.
2.
Sitting on the seat, engage the parking brake and
move the blade-control switch (PTO) to the O
FF
position. Move either motion-control lever (out of the
N
EUTRAL
-
LOCK
position). Try starting the engine; the
engine should not crank. Repeat for the other control
lever.
3.
Sitting on the seat, engage the parking brake, move the
blade-control switch (PTO) to the O
FF
position, and
move the motion-control levers to the N
EUTRAL
-
LOCK
position. Now start the engine. While the engine
is running, release the parking brake, engage the
blade-control switch (PTO) and rise slightly from the
seat; the engine should stop.
4.
Sitting on the seat, engage the parking brake, move the
blade-control switch (PTO) to the O
FF
position, and
move the motion-control levers to the N
EUTRAL
-
LOCK
position. Now start the engine. While the engine
is running, center either motion control and move
(forward or reverse); the engine should stop. Repeat
for other motion control.
5.
Sitting on the seat, disengage the parking brake,
move the blade-control switch (PTO) to the O
FF
position, and move the motion-control levers to the
N
EUTRAL
-
LOCK
position. Try starting the engine; the
engine should not crank.
Driving Forward or Backward
The throttle control regulates the engine speed as measured
in rpm (revolutions per minute). Place the throttle control in
the F
AST
position for best performance.
CAUTION
Machine can spin very rapidly. You may lose
control of machine and injure yourself or damage
the machine.
•
Use caution when making turns.
•
Slow the machine down before making sharp
turns.
