How It Works
Detents inside the switch give it 3 positions: OFF, RUN,
and START. The START position is spring loaded so the
cylinder automatically returns to RUN once the key is
released (Fig. 350).

To gain access to the neutral safety switches, remove
the front pocket. There are 2 neutral switches. One
for the right motion control handle and one for the left
motion control handle (Fig. 351).
Used to ensure the motion control handles are in neutral
to start the unit. It is activated by moving the motion
control handles to the neutral position (handles outward).

Testing
1. Disconnect the switch from the wiring harness
2. Verify that continuity exists between the terminals
listed for the switch position. Verify that there is NO
continuity between terminals not listed for the switch
position.
OFF No continuity between terminals
RUN Continuity – B I A XY
START Continuity – B I S
