CHECKING THE INTERLOCK
SWITCHES
The machine has interlock switches in the electrical system.
These switches are designed to stop the engine when you get off
the seat while either the PTO lever is engaged or the traction
pedal is depressed. However, you may get off the seat while
the engine is running. Although the engine will continue to run
if the PTO lever is disengaged and the traction pedal is released,
it is strongly recommended that the engine be stopped before
dismounting from the seat.
Do not disconnect the interlock switches.
Check operation of the switches daily to assure
the interlock system is operating correctly. If a
switch is malfunctioning, replace it before oper-
ating the machine. To ensure maximum safety,
replace all switches after every two years or
1,000 hours, whichever comes first.
To check operation of the interlock switches:
1. Move the PTO lever to OFF and remove your foot from
the traction pedal so it is fully released.
2. Try to start the engine. If the engine starts, go to step 3. If
the engine does not crank there may be a malfunction in
the electrical system.
3. Raise off the seat and move the PTO lever to ON while the
engine is running. The engine should stop. If the engine
stops, the PTO switch is operating correctly so go to step
4. If the engine does not stop there is a malfunction in the
safety interlock system.
Do not operate the machine without an imple-
ment unless the PTO drive shaft is also
removed.
4. Move the PTO lever to OFF. Raise off the seat and
depress the traction pedal slowly while the engine is run-
ning. The engine should stop. If the engine stops, the neu-
tral switch is operating correctly. If the engine does not
stop, there is a malfunction in the electrical system.
