5.2 During Use:
5.2.1 Accelerator rotary knob: used to control travel direction and truck speed. When performing travelling operations,
first pull the operation tiller to area B. when the tiller is in area A or C, the truck will be powered off and unable to
travel. When the operation tiller is in area B, and rotate the accelerator rotary knob to one direction the truck will travel
to that direction, and the travel speed will increase along with the rotation amplitude. When you rotate the knob to
another direction, the travel will travel to that direction, and the travel speed will increase along with the rotation
amplitude.
Note: The driving wheel motor is equipped with brake, and the spindle which controls the rocker arm is equipped with
cam and micro switch. Only when the rocker arm is 45°±35° (as shown in figure 2), will the stacker be allowed to
be powered on. When the angle is bigger or smaller, the stacker will be powered off, and lifting operations will be
allowed. The truck cannot travel while lifting cargo, i.e. as shown in figure 2, when operation tiller is in area A or C,
the truck can only lift or lower, and travelling is not allowed; when operation tiller is in area B, the truck can both lift
and lower. In the following text, work position of operation handle will not be mentioned again, i.e. when operation
tiller is in area A or C, the truck cannot travel, but only lift or lower. When the truck travels, the operation tiller is surly
