 Prior to: 

 The oil level in a fuel tank height is two-thirds of the tank height of 
 (b) the oil return valve is reliable role 
 (c) pull oblique iron bodies flexible and reliable (d) connections are tight parts are loose and oil spills 

 Steps: 
 Rail joints regulator pushed to adjust the rail joints 
 Move to pull the rack, the two fixtures (Oblique iron) falls on rail, so that the oblique iron rail clip prison 
 Tighten the oil return valve clockwise to shake the joystick, so that the working cylinder of high pressure oil input 
 After each adjustment shall be the order of first unscrew the oil return valve, then release the oblique iron working cylinder Lahuang role next time 
 Shaking pull the rack so that toward the wheel support rails on the move to the second operating point
