OPERATING INSTRUCTIONS

1.  Cut a 5' length of 1" RIGID conduit and insert it into the ratchet arm as  

    shown in Figure 1. This will serve as the ratchet handle.
2.  Place the ratchet handle in the up position. This will release the ratchet pawl.  

    Rotate the bending shoe counter-clockwise. Then lower the ratchet handle.

3.  Slide the conduit to be bent  

    over the corresponding size  

    on the conduit support unit,  

    through the shoe groove and  

    bending hook.
4.  Place the bending mark on the  

    conduit in line with the front  

    edge of the bending hook.  

    See Figure C on page 6.
5.  Raise the ratchet handle until  

    the pawl clicks. Push the ratchet  

    handle down. Repeat until you  

    have completed the desired bend.

6.  To remove bent conduit, raise the ratchet handle to the up position.  

    Remove the ratchet handle from the ratchet arm and slide it into the pocket 

    provided on the bending shoe. While holding the bent conduit, slowly  

    rotate the bending shoe in the counter-clockwise direction and remove  

    the bent conduit. 
7.  Place the ratchet handle back into the ratchet arm and lower the ratchet  

    handle to the down position.
    NOTE: 

Springback compensation is not calculated on the 

    bending degree indicator.

    NOTE: 

When not in use the ratchet handle MUST remain in 

    the down position.
