Af ter insta l lat ion, connectthe power to the power uni t , the gear begin towork and the hydraul ic o i l enter the oi l cy l inderand push the pi ton rod up, which cause the chainl i f t carr iage and arm. Since the minimum l i f t ingheight of the equipment is qui te loW this devicecan be used widelv.
