1. Your straightener is fully assembled and ready to be put

into position. Visually inspect unit for damaged or loose
parts due to shipment. If there is physical damage contact
carrier.

2. Install your straightener on a level surface with sufficient

clearance for loading material and adjusting the roller
pressure for straightening. Align and center your unit to
the device that will be supplying the stock. For safe operation,

bolt unit to the floor. Before bolting your unit to the floor, check

for the longest feed length and position your straightener so
that there will be about two or three feed lengths in the storage
loop without re-inducing coil set in the material.

CAUTION - Disconnect electrical power before performing
any service to this machine.

INSTALLATION

3.

Before inserting material into your straightener, turn on the main
power button and run a test cycle using the jog button. Also run
a test cycle in the run mode using the dancer arm to test that the
speed varies if using the proportional control. Test all other
electrical features before continuing.

4.

Once these tests have been completed and all the functions are
working properly, your straightener can now be used for what it
was designed to do and that is to remove coil set.

OPERATION

1.

Retract the upper pinch roll and upper idler roll platen to a
position so that when the cover is closed the material is not
being deformed. Open the cover of the straightener and
position the edge guides for the maximum width. Cut and place
about a four foot length of material onto the straightener rolls
with the exit end of the material extending through the exit
pinch rolls and centered from side to side in the straightener.
Close the cover and latch it. Adjust the exit pinch roll enough
to grip and hold the material. Adjust the edge guides so that
they just touch the material.

2.

Adjust upper idler roll platen (using platen adjusting knobs) to
remove coil set. Most of the coil set should be removed with
the roller closest to the entrance end of the straightener with
declining adjustment as material passes through the rollers
closest to the exit end of the straightener. Never overwork the
material to the point where opposite coil set is established.

3.

Depending on the amount of coil set in your material and the
type of material you are trying to straighten, you may be
required to run the material through the straightener several
times with several adjustments before the required results
are achieved.

4. Refer to the Tech. Bulletin on page 4 in this manual for material
straightening procedures.

In the Stop mode there is no movement of the rolls.

On/Off switch

This illuminated switch is the main power switch for the
controller. It must be "ON" for the straightener to function.

Reset switch

This is the main circuit breaker for the straightener.

and lower straightening rolls will turn.

Loop arm/external switch

When using a dancer arm, select loop arm button to display
"LV" for vertical. This button will also allow you to select
"LH" for horizontal. ("LH" is used for Pallet Master decoilers
only)

When using an external loop control, select external loop to
display "RT" for RTB or "RS" for RS2.
