SERVICE HINT When replacing or installing

nylon air line tubing into

quick-connect fittings it is

line is cut square. Improper

cut of the end of the air line

tubing can cause the air line

quick connect fitting causing

air leakage.

INSTRUCTIONS CAN RESULT IN PREMATURE AIR SPRING FAILURE, CAUSE PERSONAL INJURY,

OR PROPERTY DAMAGE.

ENSURE THAT ALL PERSONNEL AND EQUIPMENT ARE CLEAR FROM UNDER THE VEHICLE AND

AROUND THE SERVICE AREA, FAILURE TO DO SO CAN CAUSE SERIOUS PERSONAL INJURY,
