1. Position ignition/emergency stop switch to on. If
machine has been shut down, start engine and
allow warm-up period before beginning any lifting.
2. Position pump and engine control switches to
desired positions (high or low) and position drive
control switch to desired position (torque or speed).
3. Position controller to forward, pull up on safety lock,
and hold controller in position for duration of travel.
Once drive is initiated, the safety lock can be
released and drive will continue to function until con-
troller is returned to the center off position. Drive
speed is determined by the distance the controller is
moved from the center off position.
