Description

The Greenlee hydraulic punch driver sets combine

the 746 Hydraulic Ram with the 767 Hand Pump or
the 1725Foot Pump. These hydraulic driver sets

are intended to be used with either standard or

Slug-Buster® punches and dies to punch holes through
plastic, berglass, aluminum, and steel. Greenlee
Slug-Splitter® punches, dies, and draw studs are

capable of punching through all of these materials and
stainless steel.

Round punches are available for punching holes from

12.7 mm through 144 mm (1/2" through 5-5/8") in
diameter, including 1/2" through 5" conduit and pipe
sizes. Other shapes are available — square, special
square, rectangular, “D”, double “D”, electronic connec­tor, oiltight with notches, and key.

The maximum thickness of material that the punch can

penetrate depends on the size and shape of the punch.
Refer to the instruction manual supplied with the punch
for individual punch capacities.

IMPORTANT SAFETY INFORMATION

SAFETY
ALERT
SYMBOL

This symbol is used to call your attention to hazards
or unsafe practices which could result in an injury or

property damage. The signal word, dened below,

indicates the severity of the hazard. The message
after the signal word provides information for pre­venting or avoiding the hazard.

Immediate hazards which, if not avoided, WILL result

in severe injury or death.

Hazards which, if not avoided, COULD result in

severe injury or death.

Hazards or unsafe practices which, if not avoided,
MAY result in injury or property damage.

Read and understand all of the
instructions and safety information
in this manual before operating or
servicing this tool.

Failure to observe this warning could

result in severe injury or death.

Hydraulic Punch Driver

Electric shock hazard:

Do not use this tool near live circuits.

This includes, but is not limited to, the
following:

• near circuit breaker panels or fuse

boxes with energized circuits

• near junction boxes with energized
circuits

Failure to observe this warning could

result in severe injury or death.

Skin injection hazard:

• Hand-tighten all couplers com-

pletely before operating the pump.
Do not use tools to tighten the
couplers.

• Do not use hands to check for
leaks.

• Do not hold hose or couplers while

the hydraulic system is pressurized.

• Release the hydraulic pressure
before disconnecting the hoses or

couplers, and before servicing the

pump or accessory.

Oil under pressure easily punctures

skin causing serious injury, gan-

grene or death. If you are injured by

escaping oil, seek medical attention

immediately.

Greenlee / A Textron Company 4455 Boeing Dr. • Rockford, IL 61109-2988 USA • 815-397-7070

Wear eye protection when operating

or servicing this tool.

Failure to wear eye protection could

result in serious eye injury from ying
debris or hydraulic oil.

Hydraulic Punch Driver

IMPORTANT SAFETY INFORMATION

A component failure could throw
broken parts.

• Do not allow anyone to stand in

front of the punch or behind the
hydraulic ram.

• Close access doors or covers on

any equipment that is in line with
the punch or ram.

Failure to observe this warning could

result in severe injury or death.

Do not attempt to punch a hole
through two or more layers of mate-

rial. This will bend or break the draw
stud, and could throw parts with great

force.

Failure to observe this warning could

result in severe injury or death.

Set up the tool properly. An improper setup could
cause a component to fail and strike nearby person-

nel with great force.

• Thread the punch completely onto the draw stud.
All of the punch threads must be engaged by the

draw stud threads. Incomplete assembly could
cause a component failure.

• Use only Greenlee punches, dies, and draw studs.

Other manufacturers’ components might not with­stand the forces generated by this punch driver.

Failure to observe these warnings could result in

severe injury or death.

Replace worn, damaged or missing components
with Greenlee replacement parts. Worn or damaged
components can fail, resulting in injury or property

damage.

• Inspect the pump, hoses, couplers, and ttings for

wear or damage.

• Inspect all punch components (punch, die, draw
stud, etc.) for wear or damage.

Failure to observe these warnings could result in

severe injury or death.

Do not exceed the rated capacity of this tool.
Exceeding the rated capacity could cause a com-

ponent failure, which could throw broken parts with

great force.

Failure to observe this warning could result in severe

injury or death.

The punch driver will fall free when the punch is
complete.

• Support the weight of the tool when punching.

• Do not allow anyone to stand beneath an overhead

punch.

Failure to observe this warning may result in injury or

property damage.

Use this tool for the manufacturer’s intended purpose
only. Any other use may result in injury or property

damage.

This punch system was designed for a maximum

operating pressure of 450 bar (6500 psi).

• Use this punch system with the Greenlee 767 Hand
Pump or 1725 Foot Pump only.

• Connect the pump to the ram with Greenlee hoses

and couplers only.

Use of any other hoses or couplers could result in

injury from a component failure.

Setup and Operation Instructions

Hydraulic Punch Driver

1. Remove the dust caps from the couplers; attach the
hose to the ram and to the pump. Thread the dust
caps together.

Note: Hand-tighten the couplers completely until all
threads are engaged. Do not use tools.

2. Select the punch, die, and draw stud that will make

the appropriate size hole.

3. Determine and mark the exact location for the hole.
Using a drill bit that is slightly larger than the draw
stud, drill a hole. This is the pilot hole.

4. Thread the 3/4" piston shaft (B) completely into the
ram (A). Refer to the illustration.

Note: For a punch and die with a 3/8" center hole,
thread the 3/8" adapter draw stud (F) into the end of
the piston shaft. For a punch and die with a 1-1/8"
center hole, thread the screw sleeve (E) onto the
piston shaft.

5. Install spacers as necessary. Refer to the illustra­tions on this page.

6. Slide the die over the draw stud with the open end

of the die facing away from the ram.

7. Insert the draw stud through the pilot hole.

8. Thread the punch onto the draw stud with the
cutting surfaces of the punch facing the material.

Tighten the punch by hand until the spacers, die,
material, and punch are snug.

Note: All of the punch threads must be engaged by
the draw stud threads. If any of the punch threads
are not engaged, dis-assemble the setup, remove
one of the spacers, and reassemble the setup.

Do not operate the pump after ram motion stops.

Continuing to operate the pump lever after the ram

stops will damage the ram.

Note: If the ram stops before the hole is complete,
stop pumping. Check that the setup is correct
and that you have not exceeded the tool’s capac­ity. Refer to the setup instructions. If necessary,
disassemble the setup and add a spacer.

9. Activate the pump. For specic instructions, refer to

the operating manual supplied with the pump.

Note: Support the weight of the ram when operat­ing the pump. This will prevent the ram from falling
when the punch is complete.

10. Release the pressure at the pump.

Maintenance

The pump and ram require little maintenance. Use the
tool with care to keep dirt and grit out of the hydraulic
system. All internal working parts are lubricated by the
hydraulic oil, so that no other lubrication is necessary.

Repair

All repair work should be performed at an authorized
Greenlee service center. Use only Greenlee replacement
parts. Using any parts other than Greenlee replace-

ment parts may do irreparable damage and will void the
warranty.
