Squeeze Adjustment

Variation in conduit can result in wrinkling or side
marking of 1-1/2" and 2" EMT or IMC. This bender is
equipped with a unique Squeeze Adjustment feature
which enables you to increase or decrease the bending
pressure in order to make a quality bend.
Wrinkling of 1-1/2" - 2" EMT & IMC
If wrinkling occurs, INCREASE SQUEEZE by loosening
set screws and turning both adjusting bolts 1/2 turn
clockwise. Tighten set screws and make a test bend.
If wrinkling continues, repeat procedure.
Note: Both adjusting bolts must contact bender frame.
Turn bolts 1/2

Side Marking of 1-1/2" - 2" EMT & IMC
If you have difficulty loading IMC or EMT or if excessive
side marking occurs, REDUCE SQUEEZE by loosening
set screws and turning both adjusting bolts 1/2 turn
counterclockwise. Tighten set screws and make a test
bend. If problem continues, repeat procedure.

555 Electric Bender

Special Application

The 555 bender may be placed flat for special applica-
tions where unusual bends may be required. The unit is
operable in this position with the same efficiency as in
the upright mode.

Maintenance

There is no need for periodic flushing and replacing of
lube in bender gearbox since it is sealed and locked
tight. However, if the box is opened for repair and the
lube is lost or contaminated by dirt, then the box and
parts should be flushed out and filled with 26 fluid
ounces of Mobil 634 synthetic oil.
Flushing should be accomplished with kerosene. This
is a petroleum hydrocarbon which will not affect seals.
Aromatic hydrocarbons such as benzene, chlorinated
solvents such as "carbon tetrachloride" and ketones
such as "acetone" should never be used for flushing as
they are solvents for rubber.
For chain adjustment procedure see page 15.
