TESTING SAFETY SYSTEM FOR PROPER OPERATION
Notes:
Proper operation of the safety
system indicates that:
1. To start the engine, both steering
levers must be out, and the PTO
switch must be off. The engine
will start with the operator on or
off the seat and the parking
brake either on or off.
2. With the engine running and the
operator off the seat, the en-
gine will die if either steering
lever is brought in or the PTO
switch is turned on.
3. The engine will also die if the
operator gets off the seat with
either steering lever in or the
PTO switch turned on.
4. The engine will die if the steer-
ing levers are brought in with
the parking brake on.
