This system uses an interlock module, an ignition
switch and four safety switches. The interlock module is
connected to the magneto and to ground. When at rest
the module closes the connection between the magneto
and ground. The engine cannot fi re.
When in the off position the ignition switch also grounds
the magneto. To start, turn the ignition switch to on,
which will open the contacts. When the recoil is pulled
a small amount of the current from the magneto is
taken by the interlock module and sent out to the switch
circuit. This current must go through the blade switch
and transmission switch and return to the module. This
current then activates the module and it will open the
magneto ground.
Once started, the operator will engage the blade, trans-
mission or both. When either is engaged the blade/
transmission circuit opens. To prevent the module
from stopping the engine the parking brake must be
disengaged and the operator presence control levers on
the handles must be held down.
