3.1 CONTROLS & THEIR FUNCTIONS
3.1.1. OPERATOR PRESENCE CONTROL (OPC)

activated by depressing one or both of the OPC
handles located over the left and right handle grips.
See Figure 3.1.

When the Operator’s Presence Control (OPC) is
released, the machine will continue to operate a few
feet. DO NOT use this Operator’s Presence Control
(OPC) to routinely stop the machine.
WARNING
DO NOT attempt to modify, remove, or otherwise
alter the OPC in any way. Doing so may result in
serious injury or death.

traction belt while applying the wheel brake. Squeezing
the left lever turns the machine to the left, squeezing
the right lever turns the machine to the right, squeezing
both left and right levers together stops the machine.
