Installation Prior to placing the Forcer on the Platen both surfaces must be cleaned. Use this
method:
1. Apply masking tape to lamination surface of the Forcer to remove any metallic
contaminants.
2. Using alcohol, clean both surfaces to remove any adhesive residue and any
other contaminants on the Forcer and the Platen.
Note: Apply small amount of alcohol to cloth for cleaning. Never pour or drip alcohol
or other chemicals onto the forcer or platen surfaces.
3. Wax and polish Platen and Forcer surfaces. ( Turtle Wax ). Remove any visible
residue.
Adjust Air Gap Factory preset to 0.0015″.
Note: When receiving the Forcer and the Platen, the air gap is already set to
0.0015″. (Increasing the air gap will decrease the force). Use the following
instructions only if you need to reset the air gap.
1. Carefully remove the Forcer from the platen by sliding off the Forcer of the end
of the Platen. (So as not to score the Forcer and the Platen surfaces).
2. Loosen the four screws (1 turn) on the bearing kits using an Allen key.
3. Center the shim on the toothed section of the Platen.
4. Place the Forcer on the Platen. Be sure that the shim is only between the
Forcer and the Platen, and not between the wheels and the Platen.
5. Apply downward pressure on both bearing kits only (the Forcer is attached
magnetically) and then tighten the four screws to 30 in–lbs of torque.
6. Slide the Forcer down the Platen while holding the shim in place and remove
the shim.
Maintenance Waxing of the Forcer lamination for corrosion protection is recommended every month (or
as needed) depending on environmental conditions (i.e. humidity and moisture).
Operation Considerations The motor must always be operated within the specified operating parameter limits.
Exceeding those limits will permanently damage the motor.
The forcer must never touch the platen during operation. Equal horizontal and vertical air
gap must be maintained.
The following steps must be completed to ensure safe and proper operation.
1. Verify that all electrical wiring and cables are properly connected. Refer to the
manual provided with the control for this information.
2. Adjust the stepper driver current to match the motor’s current specification.
3. Strain relieve the wires prior to operating.
