ASSEMBLY STEP 3
INSTALL THE IDLER PULLEY
1. Lay the belt beside the rail, as shown. Grasp the end with the
hooked trolley connector and pass approximately 12" (30
cm) of belt through the window. Keep the ribbed side toward
the rail, and allow it to hang until Assembly Step 4.
2. Remove the tape from the idler pulley. The inside center
should be pre-greased. If dry, regrease to ensure proper
operation.
3. Place the idler pulley into the window as shown.
4. Insert the idler bolt from the top through the rail and pulley.
Tighten with a 3/8" lock washer and nut underneath the rail
until the lock washer is compressed.
5. Rotate the pulley to be sure it spins freely.
6. Locate the rail tab. The rail tab is between the idler bolt and
the trolley in the front rail section. Use a flathead screwdriver
and lift the rail tab until the tab is vertical (90º).
