flood, and then shut down the engine.
After stopping the engine, shift the joystick of
working device to UP and DOWN positions
several times in order to release the left pressure

Be sure to lock safety support up to the piston
rod of the lift arm cylinder to restrict the retraction
of lift arm cylinder, to prevent the falling down of
working device. In addition, shift the joystick to
