Maintenance (cont'd)
Zeroing the 855DX
The shoe timing is set at the factory and should never
need to be adjusted unless the encoder assembly is
removed.
1. Pivot the bending head to the vertical bending
position.
2. Press the BEND or UNLOAD button until the green
IMC/rigid hook is in the loading position (or –5°), as
shown below.

Note: The bender can be zeroed without completely
removing the shoe only if the bender is on a level
surface.
3. To zero the bender without completely removing the
shoe, follow these steps; otherwise, skip to step 4.
a. Check to make sure the bender is on a level
surface and the shoe will not slide off after it is
unlocked from the bender. If the bender is not on
a level surface, skip to step 4.
b. Check that the spoke with the arrow is at the 3
o'clock position, as shown below.
c. Remove the lock collar, and slide the shoe 1"
away from the sprocket so the drive bolts clear
the sprocket.

d. Being careful not to impact the rollers with the
shoe hooks, carefully rotate the shoe 45° coun-
terclockwise so the drive hole and round center-
ing hub behind the sprocket are visible at the
12 o'clock position.
e. Continue to step 5.
