Connect parts at the joint with the supplied 

bolts. Carefully tighten as you assemble the rail. 

DO NOT overtighten. See Figure 3-11.

Figure 3-11

When you arrive upstairs, adjust the position of 

the rail and supports while you compare with 

the drawing.

NOTE: When installing to the stairs, ensure the hardware 

is long enough. If the carpet is very thick, it might require 

longer hardware. 

Watch out for tack strips. Avoid mounting on them. If you 

can't avoid them, shims are required.

8. 

Using the angle meter, set the rail to the correct 

angles and check the drawing to verify that all 

clearances are correct. DO NOT tighten all the 

leg set screws yet, only set enough to support 

the rail. Leave the others floating.

BATTERY INSTALLATION

1. 

Install the battery. Open the front of the chassis 

by removing the screws on shroud.

red wire is connected to the red terminal on 

the other battery. Connect the black terminal 

on one battery to the red terminal on the 

other battery with the white jumper. If wired
