5.3.1The brake function can be activated by the following ways：
⚫ Turn the travel switch (2) to "0" position or release the switch to make truck
brake until it stops.
⚫ With the driving switch (2) moving directly from one driving direction to the
opposite direction, the vehicle regenerates the brake until it begins to move
in the opposite direction.
⚫ The handle moves up and down to the braking area (' B ') and the truck
brakes.If the handle is released, the handle automatically moves to the upper
braking area (' B ') and the truck stops until it stops.
Emergency Reverse button (3) can prevent the operator will be squeezed, when
trucks are driven towards (' Fw) encounters an obstacle, body touch belly to slow
down or start to switch truck (' Bw) driven a short distance, then stop.If the
