2-4. GENERAL CONTROL OPERATION. The speed control (See Figure 2-2) located on each side of the control head provides fingertip control for driving the truck. Rotate the control in the direction you want to travel. The farther you rotate the control from the neutral position, the faster the truck will travel.
To lift forks, push in either LIFT button and hold until forks reach desired height. To lower forks, push in either LOWER button and hold until forks descend to desired height. 2-9. LOADING AND UNLOADING. Move truck to location where load is to be picked Move the truck into position so forks are within pallet or skid, and the load is centered over the forks and as far back as possible.
