Neutral Safety Switch - Toro Z Master Z400 Series Service Manual

ELECTRICAL
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. 388).

Neutral Safety Switch

Purpose
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).
Location
To gain access to the neutral safety switches, remove
the panel assembly. There are 2 neutral switches. One
for the right motion control handle and one for the left
motion control handle (Fig. 389 Right Hand side) (Fig.
390 Left Hand side).
