f. Install four new .08-inch nylon pads from kit on to the front surface in the same four locations using 5/32-
inch diameter counter sunk rivets from kit and the rivet tool .
g. Remove and discard the four nylon pads from the back upper and back lower surfaces of the slider
assembly. Remove the nylon pads by cutting the rivet stems using the 5/8 cold chisel and hammer.
h. Install two new .08 inch thick nylon pads from the kit only to the back upper of the slider assembly at
each end using 5/32-inch rivets from the kit using rivet tool. Do not install new nylon pads on the back
lower surface of the slider assembly.
i. Remove the nylon pad that runs along the full length of the top surface of the slider, if installed. Cut a 3-
inch section off each end of the pad using a hacksaw and discard the middle section. Use a metal file or
sand paper to smooth and round the cut edge. Install 3-inch pads at each end of the top surface of the
slider assembly using existing holes at the ends.
j. If the slider was removed from the ladder, install the slider to the bottom rail and verify that there is a
clearance of about 1/8-inch nominal between the slider and the rail, ensuring that the slider moves freely
along the rail. Attach the slider to the ladder using bolts removed earlier. Reinstall the end cap hardware
and end cap on one end of the rail. Verify the ladder will move horizontally without binding. If the
ladder still exhibits difficulty with horizontal movement, first check the top slider to ensure there is
clearance between the top and bottom surface of the rail and the slider. The top rail must have clearance
between the top and bottom surfaces of the rail and the inside of the slider, and the top rail should not
carry any of the ladder weight. Only the bottom rail should carry the weight.
