of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equip-
ment, such as those dust masks that are specially designed to filter
out microscopic particles.

ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.
DISCONNECT POWER FIRST.
Always discon-
nect machine from power supply BEFORE making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.
EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are not approved safety glasses.
OWNER’S MANUAL. Read and understand this
owner’s manual BEFORE using machine.
TRAINED OPERATORS ONLY. Untrained oper-
ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis-
connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make workshop kid proof!
DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.
MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin-
ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.
For Your Own Safety, Read Instruction
Manual Before Operating This Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of impor-
tance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.

MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
This symbol is used to alert the user to useful information about
proper operation of the machine.

Unpacking

Model G0556/G0557 (Mfg. since 10/04) -7-
To adjust the fingers:
1. Loosen the cap screws on the fingers, then
push the fingers up into the hold down
assembly stop.
2. Making sure the fingers are held square and
tight to the hold down assembly stop (Figure
2), then tighten the cap screws to secure
fingers.
To adjust for metal thickness:
1. Loosen the setscrews on the back of both
sides of the hold down assembly.
2. Rotate the eccentric on the back of the hold
down assembly. The hold down assembly will
move in and out, moving the front of the fin-
gers toward or away from the apron face
3. When the fingers are adjusted to the proper
offset and are parallel to the apron face and
base, tighten the set screw to secure the
eccentric. Note—The offset between the front
edge of the finger and the face of the apron
needs to be approximately 11⁄2times the
thickness of the material being bent or great-
er. It cannot be less than 11⁄2times or dam-
age will occur to the finger knife edge.
4. Loosen the two turnbuckle hex nuts on each
side of the hold down assembly (Figure 3).
A. Hold Down Assembly
B. Hold Down Stop
C. Fingers
D. Finger Knife Edge
E. Apron Face
F. Apron
Figure 3. Turnbuckle.
5. Adjust the hold down assembly for the metal
thickness, using the turnbuckle on each side
of the hold down assembly. The holding pres-
sure should be great enough to hold the
metal from moving when bending, but not so
tight that the hold down handle is hard to
operate.
6. When the desired tension is reached, tighten
hex nuts on each side of the hold down
assembly.

Loose hair and clothing
could get caught in
equipment and cause
serious personal injury.
Keep loose clothing
rolled up and long hair
tied up and away from
moving equipment.
SECTION 3: OPERATIONS
The fabrication of metal is a process which takes
many years to learn and perfect. The steps below
will help you in getting started with this process,
and make it more enjoyable.
Bending metal procedures:
1. Lift the hold down handle to open the hold
down assembly all the way.
2. Insert the sheet metal workpiece between
the hold down assembly and the body.
3. Align the fingers of the hold down assembly
to the bend mark on the workpiece.
4. Move the hold down handle to hold the work-
piece with the hold down assembly. Note—
Do not force the hold down handle. If the
handle is hard to put in the locked position,
the brake may need to be adjusted for the
workpiece thickness. The clamping pressure
of the hold down assembly needs to be just
tight enough to hold the workpiece from mov-
ing when bending.
5. Lift up on the apron handles (using both
hands) until the workpiece has reached the
desired angle.
6. Lift the hold down handle to open the hold
down assembly then remove the bent work-
piece. Note—If a pan or box bend is desired,
choose a die or a selection of dies that are as
close as possible to the length of pan or box
side.
