General Safety Rules*
WARNING
Read all safety warnings and instructions. Failure
to follow the warnings and instructions may result
in electric shock, fire and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS
FOR FUTURE REFERENCE!
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work Area Safety
• Keep your work area clean and well lit. Cluttered or
dark areas invite accidents.
• Do not operate power tools in explosive atmo-
spheres, such as in the presence of flam mable
liquids, gases, or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and by-standers away while oper-
ating a power tool. Distractions can cause you to lose
control.
Electrical Safety
• Power tool plugs must match the outlet. Never
modify the plug in any way. Do not use any adap ter plugs with earthed (grounded) power tools.
Un modified plugs and matching outlets will reduce
risk of electric shock.
• Avoid body contact with earthed or grounded sur-
faces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electrical shock
if your body is earthed or grounded.
• Do not expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the risk
of electrical shock.
• Do not abuse the cord. Never use the cord for
carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or
moving parts. Damaged or entangled cords increase
the risk of electric shock.
• When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of a GFCI reduces the
risk of electric shock.

Personal Safety
• Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not
use a power tool while you are tired or under the
influence of drugs, alcohol, or medication. A mo -
ment of inattention while operating power tools may
result in serious personal injury.
• Use personal protective equipment. Always wear
eye protection. Protective equipment such as dust
mask, non-skid safety shoes, hard hat, or hearing
protection used for appropriate conditions will reduce
personal injuries.
• Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energizing power tools that have the switch
on invites accidents.
• Remove any adjusting key or wrench before turn-
ing the power tool ON. A wrench or a key left
attached to a rotating part of the power tool may result
in personal injury.
• Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewel ry. Keep your hair, clothing, and gloves away
from moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts.
• If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
Power Tool Use And Care
• Do not force power tool. Use the correct power tool
for your application. The correct power tool will do the
job better and safer at the rate for which it is designed.
• Do not use power tool if the switch does not turn it
ON and OFF. Any power tool that cannot be controlled with the switch is dangerous and must be
repaired.
• Disconnect the plug from the power source and/or
the battery pack from the power tool before making any adjustments, changing accessories, or
storing power tools. Such preventive safety mea-
sures reduce the risk of starting the power tool accidentally.
Hydraulic Pipe Bender
• Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the pow er tool or these instructions to operate the power
tool. Power tools are dangerous in the hands of un -
trained users.
• Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s op er ation. If damaged, have the power tool repaired
before use. Many accidents are caused by poorly
maintained power tools.
• Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations dif-
ferent from those intended could result in a hazardous
situation.
Service
• Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.

Hydraulic Pipe Bender
Figure 15 – Angle Indicator – End of Bend
Watch the ram as it extends. If you can see a small
groove in the ram
(Figure 16)
, stop advancing the ram
to prevent hydraulic leaks and ram damage
4. For certain sizes of pipe (21/2", 3"), a ram extension
must be used to form a 90 degree bend. When the
groove in the ram
(Figure 16)
is visible, stop advancing the ram. Make sure that the pipe is properly supported to prevent it from moving or falling. Turn the
release knob to the retract position, and retract the
ram far enough to allow the extension to be inserted
between the end of the ram and the former. Insert the
extension and carefully advance the ram. Do not
place your fingers, hands or other body parts in a
position that would allow them to be trapped or
crushed.

3. Continue to advance the ram and bend the pipe. As
the pipe is bent, the ends will move. Stay clear of
the moving pipe. Monitor the angle indicators
(Figure
15).
The average of the angles measured by each
angle indicator equals the approximate total angle
bent.

As the desired degree of bend is reached stop ad vancing the ram. Do not try to create a bend of more
than 90 degrees (per the angle indicator), this could
cause kinking of the pipe and other issues. A square
or other measuring device may be needed to measure exact bend angles. It is preferable to under
bend the pipe as it is easier to bend the pipe a little
more than to straighten it. When the ram is retracted,
the pipe may spring back, so you may need to slightly compensate to get the desired angle.
5. With the bend complete, move the ON/OFF switch to
the OFF ( ) position. Retract the ram by turning the
release knob to the retract position.
6. Remove the pipe from the bender. If needed, remove
pins, corner supports and/or open the top wing. If
the former is stuck to the pipe, a block of wood or a
soft faced hammer can be used to tap the former off
the pipe. Do not use regular hammers, chisels or
other hardened tools to remove the former. They
can chip and damage the former and cause injury.
Straightening Bends
A straightening former is available to slightly reduce the
angle of a bend (up to approximately 10 degrees). Use of
the straightening former may deform the bend. In some
cases (such as 90 degree bends on 2
1
/2" or 3") the
straightening former cannot be used. To use:
1. Place the straightening former on the end of the ram.
2. Place the pipe so that the bend sits against the
straightening former and the legs of the bend are

against the corner supports. Make sure the set up is
symmetric, with the corner supports in the correct
position, to prevent damage to the bender.

Maintenance Instructions
WARNING
Maintain the hydraulic bender according to these
procedures for a longer product life and to reduce
the risk of injury from electrical shock and other
causes.
Cleaning
After each use, wipe any oil or dirt off of the bender and
formers with a clean, dry, soft cloth. Pay special attention
to the ram and piston to remove any dirt or debris that
could scratch polished parts or damage seals. If needed,
the formers and corner supports can be cleaned with a
wire brush.
Lubrication
Monthly, or more often if needed, apply a light machine oil
or grease to handle pivot points, wing hinge, and pins. Do
not apply oil to hydraulic system components.
Hydraulic Oil
Checking Level/Adding Hydraulic Oil
Before each use, check oil level. Place the bender on a flat
level surface with the ram fully retracted. Remove the oil
vent cap – oil should be even with the bottom of the fill
neck. If oil is needed, add Shell Tellus 32 Hydraulic Oil or
other equivalent high quality hydraulic oil and replace oil
vent cap. See
Figure 10
for location of oil vent cap.

NOTICE
Changing
Once a year, or more often with heavy use or use in
dusty conditions, the hydraulic oil should be changed.
Place the pump end of the hydraulic cylinder in a container
to collect the hydraulic oil as it is drained. Directly under
the cylinder is a plug
(Figure 19)
. Remove the plug, filter
spring and filter and allow the hydraulic fluid to drain.
Open the oil vent cap and raise the ram end of the cylinder slightly to improve drainage. Complete drainage may
take up to several hours. Properly dispose of the used
hydraulic oil per the Material Safety Data Sheet (MSDS)
and local requirements.
Figure 19 – Hydraulic Oil Drain Plug and Access to Filter
Clean the filter by rinsing in clean hydraulic oil. Re-install
the clean or new filter, spring and plug. Fill the bender with
new hydraulic oil following the instructions for adding
hydraulic oil. Operate the bender through several cycles
to remove air from the system and check the hydraulic oil
level.
Low Temperature Operation
If the Hydraulic Bender will be used in low temperatures
(Less than 14°F (-10°C)) it is recommended that the
Hydraulic oil be changed to a high quality Hydraulic oil suitable for the temperature.
