WARNING

ELECTRIC SHOCK HAZARD! Only connect the bender to a 20 amp GFCI protected circuit. Do NOT modify the plug which is provided with the unit. Failure to follow these warnings can result in serious injury or death.

This bender is intended for use on a circuit that has a receptacle that looks like the one illustrated below. The bender has a grounding plug that looks like the plug illustrated below.

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. The bender is equipped with an electric cord having an equipment grounding conductor and a grounding plug. Only connect the bender to a 20 amp GFCI protected receptacle which is properly installed and grounded to meet all applicable electrical codes. DO NOT use an adapter.

DO NOT modify the plug provided. If it will not fit the receptacle, have the proper receptacle installed by a qualified electrician.

Improper connection of the equipment grounding conductor can result in risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.

Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the bender is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the bender’s plug.

Repair or replace damaged or worn cord immediately.

If the Bend Angle Limit Switch becomes too loose or too tight, the

spring tension can be adjusted as follows:

• Disconnect power to the bender.

• To access the Bend Angle Limit Switch, remove the 14 screws that hold the face plate onto the bender frame.

• To adjust the spring pressure, loosen or tighten the 2 hex nuts (Item #125).

• Check the tension by sliding the Bend Angle Limit Switch in the slot.

• Reinstall the face plate.

5. Roller Supports:

• We recommend lubrication of the built-in support roller system rollers and roller support unit rollers every 6 months. Use a good quality MP grease. A grease fitting is provided for the roller support cam shaft (see item #91, page 40).
