Description
The 1731 Hydraulic Punch Driver is intended to be
used for punching holes in panels and enclosures.
The C-Frame design eliminates the need for a pilot hole,
making the punch process a one-step operation.
The 1731 punch kit contains standard Greenlee
punches and special C-Frame dies for punching 1/2",
3/4" and 1" conduit size holes. Optional punches and
dies are available for 1-7/32" and metric sizes Pg-9
(15.2 mm), Pg-11 (18.6 mm) and Pg-13 (20.4 mm). The
maximum capacity is 10 gauge mild steel.
The 1731 is designed to be used with the Greenlee
model 767 Hand Pump and 1725 Foot Pump only.

IMPORTANT SAFETY INFORMATION
Keep hands away from punch and die
during operation.
Inspect punch driver, pump, hoses, and couplers.
Also inspect the punches, dies, and adapters.
Replace any worn, damaged, or missing components
with Greenlee replacement parts.
Support C-Frame when punching.
The C-Frame will be unsupported and
may fall when the hole is nished.
Wear protective gear. Beware of metal
chips and sharp edges.
Do not operate without the roll pin (30) in place.
Without this roll pin in the path of the slug, the slug
will exit the C-Frame with sufcient force to cause
serious injury.
• Use only with power sources listed in this manual.
Use of other pumps may cause the punches and
dies to chip, split, or break.
• Use this tool for the manufacturer’s intended
use only.
• Work in areas providing good footing
and support.
• Work in areas that are well-lit, uncluttered,
and dry.
Failure to observe these precautions could result in
injury or property damage.

Operation
1. Select the proper combination of punch and die.
See Adapter Selection Table to select the
corresponding punch adapter.
Inspect punch driver, pump, hoses, and couplers.
Also inspect the punches, dies, and adapters.
Replace any worn, damaged, or missing components
with Greenlee replacement parts.
2. Insert the die into the C-Frame and secure it by
tightening the set screw.
Note: Check the die’s exit path for the roll pin (30).
The roll pin sits directly in the exit path to slow the
slug as it exits the C-Frame.
Do not operate without the roll pin (30) in place.
Without this roll pin in the path of the slug, the slug
will exit the C-Frame with sufcient force to cause
serious injury.
3. Thread the punch onto the punch adapter. Slide the
punch adapter into the C-Frame and turn it clock-
wise until the adapter is seated completely.
4. Remove the dust caps from the hydraulic pump
and from the punch unit. Connect the hose to the
C-Frame.
Note: Hand-tighten the couplers completely.
Engage all threads. Do not use tools.
5. Draw cross hairs on the material to be punched.
Align the cross hairs with the points of the punch or
the alignment marks etched into the die.
Support C-Frame when punching.
The C-Frame will be unsupported and
may fall when the hole is nished.
6. Use the hydraulic pump to advance the ram until the
punch is completely through the material. Retract
the ram. For specic instructions, see the manual
for the hydraulic pump.

Disassembly
Before servicing C-Frame:
• Depressurize the hydraulic system.
• Disconnect hydraulic hoses from tool. Remove
lines, ttings or components slowly to release any
trapped pressure.
Failure to observe these warnings could result in
severe personal injury or death.
Disassembly should be done on a at, clean surface.
Some parts may fall free during disassembly. To prevent
part loss or damage, keep the tool as close to the
working surface as possible.
Inspect all parts as they are disassembled. Inspect
mating parts and mating surfaces in the tool for signs of
damage and wear. Replace any parts which appear to
be damaged.
When disassembling tool, O-rings, backup rings and
nylon washers should be replaced.
1. Remove the ram (1-12) from the C-Frame (24A).
To do this, remove the large retaining ring (32) from
the cylinder (7).
2. Pull the ram out of the C-Frame and place it in a
vise.
3. Remove the spring retainer screw (9) from the cylin-
der end of the ram.
4. Pull piston (2) out of the cylinder (7).
5. Place piston in vise.
Note: Use the pad jaws of the vise to protect the
piston.
6. Remove roll pin (3) from piston (2) and remove
adapter unit (C). If necessary, push the tip of a large
screwdriver between the inside wall of the piston
(2) and the spring (6). Twist the screwdriver to apply
side pressure to the spring (6). Maintain pressure on
spring and loosen the other retaining screw (9).
Note: In most cases, it will be necessary to replace
both spring retainers (5) as well as the spring (6)
because it is difficult to remove spring retainers from
the spring.
7. Adapter unit (C) may be disassembled by removing
set screw (18).
Assembly
1. If necessary, screw the spring retainer (5) into both
ends of the spring (6). Spring retainers should be
ush with the end of the spring.
2. Install spring (6) with retainers (5) into piston (2).
3. Install nylon washer (4) or (4A) onto screw (9) and
tighten in spring retainer. (If necessary, use screw-
driver to wedge spring.)
4. Apply a little grease or oil on O-ring (12) and backup
ring (11). Install piston (2) into cylinder (7).
5. Install nylon washer (4) or (4A) onto screw (9). Screw
in spring retainer screw (9) and tighten until snug.
6. Retest for leaks.
7. Push ram (1-12) through hole in C-Frame (24A).
Place retaining ring (32) into groove on cylinder (7).
