OPERATION (CONTINUED)

INSIDE EDGE SYSTEM

In the stop position the brake pad is applied to the inside edge of the flywheel, at the same time the ignition system
is grounded (diag. 3).

In order to restart the engine, the brake control must be applied. This action pulls the brake pad away from the inside
edge of the flywheel and opens the ignition kill switch. On electric start systems the starter is energized by an
ignition switch or a two motion control. On non-electric start systems, the recoil starter rope must be pulled to start
engine (diag. 4).

COMPONENTS

Both the Bottom Surface and the Inside Edge systems
use the following components:

The brake lever and pad assembly consists of a steel
lever with a brake pad bonded to the lever (diag. 5).

The ignition kill switch is a plastic block with a wire
extending out of it. The wire is attached to a terminal
which is connected to the ignition kill wire. The brake
lever contacts and grounds the wire of the switch when
the engine / blade control is released, and the ignition
module is grounded. This in turn kills the ignition (diag.
5).

The  interlock switch is a push button switch that is
activated by the brake lever when the engine / blade control
is actuated. If there is a starter switch used to start the
engine, the interlock switch acts as a safety switch and
will not allow the starter to crank unless the
engine / blade control is depressed.

Where a two motion control is used the interlock switch
is utilized as the starter switch.

The Torsion Spring supplies the pressure to the brake
lever and brake pad to stop the flywheel.

The  Control Cable transfers the motion of the
engine / blade control to the brake system.
