IMPORTANT SAFETY INFORMATION

• Conduit moves rapidly as it is bent. The path of

the conduit must be clear of obstructions. Be sure

clearance is adequate before starting the bend.

• Do not operate the bender while wearing loose

clothing. Loose clothing can get caught in moving

parts.

• Inspect the bender before use. Replace worn,

damaged or missing parts with Greenlee replace-

ment parts. A damaged or improperly assembled

component could break and strike nearby

personnel.

• Some bender parts and accessories are heavy

and may require more than one person to lift and

assemble.

• Use this tool for the manufacturer’s intended

purpose only. Use other than that which is in-

structed in this manual can result in injury or

property damage.

Failure to observe these precautions can result in

injury or property damage.

Unplug the bender before changing accessories.

Accidental start-up can result in serious injury.

Pinch points:

Keep hands away from bending

shoe, rollers and conduit when

bender is in use.

Failure to observe this warning can

result in severe injury or death.

Extension cords:

• Use only three-wire, 12-gauge

extension cords that have three-

prong grounding-type plugs and

three-hole receptacles that accept

Grounding Instructions

This tool must be grounded. In the event of a malfunc-

tion or breakdown, an electrical ground provides a path

of least resistance for the electric current. This path of

least resistance is intended to reduce the risk of electric

shock.

This tool’s electric cord has a grounding conductor and

a grounding plug as shown. Do not modify the plug.

Connect the plug to a corresponding GFCI-protected

receptacle that is properly installed and grounded in

accordance with all national and local codes and

ordinances.

Do not use an adapter.

120-Volt Plug and Receptacle

Electric shock hazard:

• Do not modify the plug provided

with the tool.

• Connect this tool to a grounded

receptacle on a 15 amp GFCI-

protected circuit.

Failure to observe these warnings

can result in severe injury or death.

Mounting Bending Shoes

Choose desired shoe size (Rigid; IMC; EMT) and slide it

onto the main shaft as in Fig.1.

Setup

Next, align the four drive studs on the back side of shoe

(Fig. 2) with the 4 holes in the main drive sprocket. Push

the shoe onto the main drive sprocket.

Figure 1

Mounting Support Roller and Support Units

Choose desired support roller or support unit and

corresponding shoe size (Rigid; IMC, EMT).

Mount the support roller or support unit on the right leg

of the bender as you face the unit. Secure the support

roller or unit with the quick release hinge pin (see Fig. 3).

To release the pipe or conduit push the control switch

to the UNLOAD position. Allow shoe to rotate, drop

the unit support (see Fig. 6) and remove conduit

(see Figs. 7 & 8).

Wear eye protection when operating

or servicing this tool.

Failure to wear eye protection can

result in serious eye injury from

dimensions can be found in charts on pages 16-25 of

this manual or on the bender decals. At this point, make

sure the shoe is rotated to 5°to 10°before the 0°

setting. After marking the pipe or conduit, place it into

the bender unit as shown in Fig. 4. This requires sliding

the pipe or conduit over the correct size support unit

through the shoe groove and into the hook. Position

Mark 2 at front edge of hook (see Fig. 4).

Push the control switch to the BEND position; when the

pointer on the shoe reaches the required bend angle

(Chart B), release the control switch and the bender will

stop (see Fig. 5). Due to springback in pipe/conduit

some overbending is necessary to accomplish desired

bend angle. For this reason Chart B and/or decal on

bender show the required pointer position for desired

bend angle.

1-1/2" and 2" IMC and EMT Conduits

Refer to Setup for mounting selected IMC shoe and

support unit (see Figs. 1,2,3 & 9).

Note: The outside roller on the support unit for IMC

conduit has a metal roller while the outside roller on the

support unit for EMT conduit has a urethane roller.

Bending Instructions (cont’d)

With the shoe rotated 5°to 10°before 0°˚ slide the

conduit over the support rollers, through the shoe groove

and hook, after conduit has been properly marked

(Fig. 10). Step on the loading peddle, raising the proper

rollers to contact the conduit (Fig. 10).

Keeping foot on loading peddle, push control switch to

the BEND position. Conduit will then pull support rollers

assembly against stop. At that time foot pressure should

be removed from loading peddle. Keep control switch in

BEND position until the pointer on shoe reaches desired

bend.

To release the conduit, push the control switch to the

unload position. Allow shoe to rotate, dropping support

rollers, then remove conduit (Fig. 11), and examine the

bend. If wrinkling or if excessive side marking is present,

see the squeeze adjustment procedure.
