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 PTO is disengaged.
The motion control levers are in the brake position.
The safety interlock system also is designed to stop the
engine when the control levers out of brake position and
you rise from the seat when the PTO is engaged.
Testing the Safety Interlock
System
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. While sitting on the seat, with the control levers in
brake position, and move the PTO to On. Try starting
the engine; the engine should not crank.
2. While sitting on the seat, move the PTO to Off. Move
either motion control lever to the center, unlocked
position. Try starting the engine; the engine should not
crank. Repeat with the other motion control lever.

3. While sitting on the seat, move the PTO to Off, and
lock the motion control levers in neutral. Start the
engine. While the engine is running, move the motion
control levers to the center, unlocked position, engage
the PTO, and rise slightly from the seat; the engine
should stop.

Driving Forward or Backward

The throttle control regulates the engine speed as measured
in rpm (revolutions per minute). Place the throttle control in
the Fast position for best performance. Always operate in
the full throttle position.
Caution
The machine can spin very rapidly. The operator
may lose control of the machine and cause
personal injury or damage to the machine.
Use caution when making turns.
Slow the machine down before making sharp
turns.
Forward
1. Move the levers to the center, unlocked position.
2. To go forward, slowly push the motion control levers
forward (Fig. 9).
