This saw has a parking brake on the rear drive wheel. It
is to be used as a passive parking brake. It is not to be
used for dynamic braking. Apply the brake only when
the machine is stationary. The brake can be engaged
manually while the engine is running. It will automatically
apply when the engine is shut off.
The brake can be overridden if the machine
has to be pushed. There is a bolt on the rear
of the motor, to release the brake turn the
bolt clockwise until it bottoms out. It must be
turned counter clockwise before the machine
is put back in service.
