As you begin to operate the truck, open the power with
switch key to turn on the current. A dial of battery volume will
show the electrical volume of batteries. According to the
requirements of loading or unloading, push the relevant switch to
control the truck. The speed regulation must be made slowly to
avoid accidents.
It is strictly forbidden to turn the drive wheel in the air with

） ） ）Security system
PPI-90 Paper Inverter’s are equipped with automatic brake
system. The brake work only when you loose the switch to
control forward and backward movement, or loose the handle.
Then the electric current will be cut off before the truck stops.
Press the red switch on the top of handle when the truck is
moving, the truck will move rest-direction immediately.
PPI-90 electric locomotive are equipped with powerful tilt resist
system. There is one safe wheel on both sides of the drive wheel.
When the truck inclines to 1.5°(5mm), the safe wheel will
reach the ground. Then 900N reacting force is acted on the truck
(having regulated in factory). The gradient rises as the reacting
force increases until the gradient reaches 5°30’ (25mm), the safe
bush locks the truck (the reacting force reaches 2000N) and the
safe wheel provides the rigid support for the truck.
4) Hydraulic part
Adopted the American Fenner Hydraulic System, the work
pressure is 16Mpa. The hydraulic system is formed in entirety and
it is compact in structure and reliable in quality and durable. The
cylinder adopts the piston rod type, with treatment chromate on
the surface of piston rod. The cylinder is wear-resisting and
stainless. The hydraulic system connects the cylinder with
high-pressure hose to make a sealed cycle.
