Introduction
The Greenlee No. 1813 Bending Table is designed to make your Greenlee No. 881 Hydraulic Bender easier to use.
Loading is faster and easier. The vertical, bench-high bending means greater control and freedom of movement for
the operator and less fatigue, too. Use of the bending table also simplifies difficult bending operations, reducing
bending time and increasing accuracy.

• Operate the power pump only at
the correct voltage and frequency
marked on the nameplate. Use a
properly grounded outlet.
• Turn off and unplug the
power pump when changing
accessories, performing service
and when idle.
• Do not operate with a damaged
cord set or with hydraulic hoses
which are abraided or cracked.
• Do not operate the power pump
in the rain or wet locations.
• Read all operating instructions.
• Clean hydraulic quick-change couplers before
making connections. Hand-tighten firmly to
engage all threads. Do not use a wrench.
• Place hydraulic control lever on power pumps in
the return position before starting the motor.
• Do not operate power equipment unattended.
• Do not operate hydraulic rams beyond (their
recommended) extended length.
• Properly position and engage all pins and rollers
before operating hydraulic bending equipment.
• Follow recommended service procedures.
• Operate power equipment in uncluttered areas
providing good footing and support.
• Keep others a safe distance from the work area.
• Use only original equipment or Greenlee specified
replacement parts and accessories.
Failure to observe these warnings could result in
severe injury or death.

Setup
Note: Two 10-foot lengths of 2" galvanized conduit are
required for the table bed. These are not
furnished with the No. 1813 Bending Table.
1. Insert each of the four legs (7) into the sockets of the
two leg supports (1), and tighten each of the four
pipe mounting screws (2).
2. Keeping one of the leg assemblies to your right,
insert the two 10-foot lengths of 2" galvanized
conduit into that assembly and tighten the four pipe
mounting screws (2).
3. With the vise to your left, slide the pipe vise unit (3)
onto the two lengths of conduit. Now slide the
bending mounting unit (4) onto the conduit, keeping
the connecting and follow bar guides to your left, as
well as the word START stamped in the unit.
4. Lift the left ends of the 2" conduit and insert each
into the left leg assembly, being certain to properly
tighten the pipe mounting screws (2).
5. Position the bending mounting unit (4) 15 inches
from the left leg assembly and tighten the pipe
mounting screws.
6. Mount the two pump support units (5) to the bending
table as follows: Hang two each of the conduit
clamps (8) on each pipe of the table bed, then space
the pump support units the approximate distance
between the mounting holes of the pump base. Do
not fully tighten the clamps, as yet.
Note: At this point, make certain your bending table is
level or you may develop wows in your bends as
a result.
Mounting the 881 Bender
1. Refer to Bulletin IM-881 to assembly the 881 ram
connecting bars and roller with the proper pins and
spring clips.
2. Position the assembled 881 bender into the bender
mounting unit (4) with the ram scale toward the side
of table where you will be operating the unit.
3. After removing the casters from the pump base,
insert the pump mounting hardware; screws, nuts,
and washers (12-15), through the pump base and
pump mounting brackets (6). Loosen clamping
screws on the pump mounting brackets and slide
the brackets attached to the pump, onto the pump
table supports (5). When the pump is in proper
position, tighten the clamping screws on the pump
mounting brackets. Now you may fully tighten all
four of the conduit clamps (8).
4. Attach the 90° coupling (9) to the ram coupling of
the bender, then connect the pump to the ram, using
the high pressure hose supplied with your bender.

Adjusting Ram Position
(2-1/2" through 4" Conduit)
1813 Bending T able
Changing Ram Positions
Setup
1. The ram positioner (10) is used to adjust the
position of the ram for the size of conduit you are
going to bend. Refer to the markings stamped on
the connecting bars for the proper ram positions for
each size of conduit.
2. Attach the yoke to the ram, using the large spring
clip as shown, in Fig. 5. Then rotate the yoke
90° from its normal position and place the ram
positioner (10) between the connecting bars as
shown in Fig. 1. Mounting tabs of ram positioner
should be up as shown in Fig. 5.
3. Apply pressure to gradually extend the ram until the
holes of the ram positioner line up with the holes of
the yoke. Then attach the ram positioner to the yoke
with the yoke pin as shown in Fig. 2.
1. Remove the small spring clips from each of the
cylinder head pins and then remove each pin as
shown in Fig. 3. You may need to apply or release
pressure on the ram in order to free the pins from
the cylinder block.
2. Use the pump to extend the ram if you wish to raise
the cylinder block—or release the pressure to lower
the block—to align it with proper set of holes in the
connecting bars for the size of conduit you are
bending. Again you may need to apply or release
pressure in short bursts in order to properly align
the holes before you can re-insert the cylinder head
pins as shown in Fig. 4.
Note: Be very careful that you do not elevate the ram
unit above the top of the connecting bars when
positioning for 4" conduit.

Bending
1813 Bending T able
1. Install the proper shoe and follow bar for the conduit
size to be bent. To make sure the follow bar is
properly centered between the connecting bars,
push the foot of the follow bar against one of the
locating guides on the side of the bender mounting
unit (4) as shown in Fig. 7. Do not allow the follow
bar to make contact with either of the bender
connecting bars.
2. Load the conduit into the bender and position for
the required bend. Attach the saddle to the shoe,
being sure to align the bending mark with the front
of the saddle.
3. Attach the Greenlee No. 1805 Bending Degree
Protractor (11) to the portion of the conduit projecting in front of the saddle. Be certain the protractor is
properly zeroed before you start each bend.
4. Strap down the other end of the conduit, using the
chain vise on the pipe vise assembly (3). Always
locate this assembly as close as possible to the end
of the conduit being bent. When bending short
lengths of conduit, be very careful to maintain
enough distance between the pipe vise assembly
and the pump support units (5). DO NOT ALLOW
THESE UNITS TO MAKE CONTACT DURING A
BEND.
5. Now make the desired bend, referring to the bending degree protractor (11) as you do so.
Note: Pipe vise assembly is designed to allow only a
1° maximum variation between bends of various
conduit sizes from 2-1/2 to 4".
