lenses; they are NOT safety glasses.
When using in dusty environment, use
face or dust mask.
Failure to wear eye protection could
result in serious eye injury from ying
debris.
• Keep guards in place and in
working order.
• Remove any tools from bender
before operating. Form habit of
checking to see that all tools are
removed from bender before
turning it on.
Failure to observe these warnings
could result in severe injury or death.
Extension cords:
• Use only three-wire, 12 AWG exten-
sion cords that have three-prong
grounding-type plugs and three-
hole receptacles that accept the

• Do not use extension cords that are
longer than 30 m (100').
• Repair or replace damaged exten-
sion cords.
Failure to observe these warnings
could result in severe injury or death.
Make sure that the handle is properly installed and
secured with the safety spring clips and snap pins
before lifting or moving the bender. An improperly
installed handle could allow the bender to fall, injuring
nearby personnel.
Failure to observe this warning could result in severe
injury or death.

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.
• Wear proper apparel. Do not wear loose clothing,
gloves, neckties, rings, bracelets, or other jewelry
which may get caught in moving parts. Nonslip
footwear is recommended. Wear protective hair
covering to contain long hair.
• Do not force rollers or alter tool. It will do the
job better and safer at the rate for which it was
designed.
• Use right tool. Do not force tool or attachment to do
a job for which it was not designed.
• Use this tool for the manufacturer’s intended
purpose only. Use other than that which is
instructed in this manual can result in injury or
property damage.
Failure to observe these precautions may result in
injury or property damage.
• Keep work area clean. Cluttered areas and benches
invite accidents.
• Keep children away. All visitors should be kept safe
distance from work area.
• Make workshop kid proof with padlocks, master
switches, or by removing starter keys.
Failure to observe these precautions may result in
injury or property damage.
• Inspect the bender before use. Replace worn,
damaged, or missing parts with Greenlee replace-
ment parts. A damaged or improperly assem-
bled component could break and strike nearby
personnel.
• Maintain tools with care. Keep tool clean for best
and safest performance. Follow instructions for
lubricating and changing accessories.
• Check damaged parts. Before further use of the
tool, a guard or other part that is damaged should
be carefully checked to determine that it will
operate properly and perform its intended func-
tion. Check for alignment of moving parts, binding
of moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation.
A guard or other part that is damaged should be
properly repaired or replaced.
• Use recommended accessories. Consult the
instruction manual for recommended accessories.
The use of improper accessories may cause risk of
injury to persons.
• Some bender parts and accessories are heavy
and may require more than one person to lift and
assemble.
Failure to observe these precautions may result in
injury or property damage.
Note: Keep all decals clean and legible, and replace
when necessary.
