Removing Shipping Clip

CAUTION! The Handle socket may be held down by a clip under tension.  Wear ANSI-
approved safety goggles before freeing Handle socket.  Remove clip carefully.

relieve tension on the wire clip.

2.  Disconnect the wire clip legs from the bar.

3.  Slowly raise the Handle Socket 

until tension is released.

4.  Remove the wire clip.

Attaching the Handle

1.  Slide the Upper Handle into the Lower Handle.  

Line the Button on the Lower Handle up with the 
hole in the Upper Handle until it clicks into place.

2.  Loosen the Handle Release Bolt and insert the 

grooved end of the Handle into the Handle Socket.

3.  Tighten the Handle Release Bolt.  Gently pull up 

on the Handle to make sure that it is secure.
