 Use 
 The hydraulic side pillow used to adjust the rail spacing and angle Founder operations. 
 Prior to: 
 a, within the fuel tank is three-quarters of the fuel tank capacity 
 b, unloading valve opening and closing the stability of the 
 c, all connections are tight parts are loose and leakage. 

 Steps: 
 A variable bit characteristics, according to the sleeper, based on the work of the rail to adjust the spacing and angle Founder asked to select the appropriate gap (not less than 275 mm), stone twitter Pa Pa or less, and equipment into the gap, the activities required head against the better sleepers thickness of the lower half of. 
 2, in advance should adjust the fastener in a sleeper on the loose (angle Founder only release the end of the fastener, required Founder at both ends of the fastener loosen all. 
 Clockwise direction of rotation unloading valve handle so that the unloading valve is closed, the joystick into the pull rod kit, shake the joystick, so that the high-pressure oil through the oil discharge valve of the pump cavity enter the working cylinder, the piston to reach out , top to move the sleeper to adjust to the operational requirements. 
 After each adjustment in order to prevent the gap after the sleepers move pad stone twitter, and then counter-clockwise to open the unloading valve, high pressure oil chamber and the fuel tank connected, cylinder piston, the role of the return spring automatically back to complete a cycle, the adjustment amount is insufficient, you can spin out of the connector, in order to achieve the maintenance requirements.
