CONTROLS

Operator Presence Control

Located on the left steering control, the Operator
Presence Control (OPC) lever is an added safety
feature. An electrical interlock safety system is
engaged when the lever is held against the left
hand steering control. When either the blades or
the speed control are engaged, the lever must
be held against the steering control to keep the
engine running.
Safety handle / speed control
Located below the steering controls, the safety
handle can be adjusted to change ground speeds
and grip span. Use the speed adjustment lock to
move the handle closer to (for slower speed) or
away from (for faster speed) the steering controls.
Speed adjustment lock
Located on the left hand side, the speed
adjustment lock adjusts the safety handle / speed
control.

Steering Controls

The machine's direction is variable using the two
steering controls. The steering controls can be
moved forward and back from a neutral position.
See Steering in the Operation section.
Ignition
The ignition switch has three positions— Stop,
Start and Run.

Throttle Control

The throttle control regulates the engine speed
and the rate of rotation of the blades, when the
blade switch is engaged.
To increase or decrease the engine speed, the
control is moved forward or back.
To prevent fouling the spark plugs, do not idle the
engine for long periods. USE FULL THROTTLE
WHEN MOWING, for best mower performance
and battery charging.
