Adjusting Chains - Greenlee 555 Instruction Manual

Adjusting Chains

The 555 bender has two chains in the power train; one is
located in the rear and one in the front. New chains will
stretch slightly; therefore, the front chain should be
adjusted after 10 to 20 bends have been made in 1-1/2"
or 2" Rigid.
To adjust front chain: loosen chain cam bolt, rotate
tightening cam clockwise until all slack is out of the
chain, and retighten cam bolt.
To access front chain: remove shoe, roller support and
front metal panel. Make sure bender is unplugged while
adjusting. Replace front guard before using.
The rear chain has a spring-loaded tensioner that does
not require any adjustment. However, if the rear chain is
removed or serviced, the rear chain tensioner should be
readjusted.
To adjust tensioner: loosen jam nut, rotate adjusting
screw until the hex head contacts the idler bracket pin,
and retighten jam nut.
Adjust until
hex head
contacts pin.
