Stairarm Installation
16 Position the stairarm in the front arm.
17 Place the shaft of a Philips screw driver into the drain hole on the bottom of the front arm and thread
one of the two 1/2-13X1 screws into stairarm. Using the installed screw, rotate the front arm bearing
until the screw driver engages into the bearing, locking the bearing. You may have to rotate the bearing
one full turn to align the bearing lock hole with drain hole.
18 Once the screwdriver has locked the bearing preventing further rotation, fully tighten the inside and
outside mounting bolts, torque to 83 foot pounds or 1000 inch pounds.
19 Remove the screwdriver from the drain hole.
