3.0 IMPORTANT SAFETY INSTRUCTIONS
WARNING – To reduce risk of injury:
1. Read and understand all safety warnings on the machine and in this manual.
2. Replace warning labels if they become obscured or removed.
3. This press is designed and intended for use by properly trained and experienced personnel only. If you are
not familiar with the proper and safe operation of a hydraulic press, do not use until proper training and
knowledge have been obtained.
4. Do not operate this press beyond its rated capacity. Use pressure gauge to determine load.
5. This press is designed for pressing, bending, and straightening purposes only.
6. Keep hands away from pressing area and pinch points.
7. Do not operate this tool while tired or under the influence of drugs, alcohol or any medication.
8. Check the press for loose or damaged parts before each operation. Replace damaged parts and tighten all
loose bolts before operating. Components are designed to withstand the rated capacity of the press – do
not substitute components.
9. Make sure workpiece is center-loaded and secure on the bed before pressing.
10. Always apply load at center of ram.
11. Remove workpiece from table before attempting to raise or lower table.
12. Some parts being pressed may have a tendency to be ejected from the press or explode under pressure.
Protect yourself accordingly, and do not allow bystanders near the machine.
13. Use good quality hydraulic pump oil only. Do not use brake fluid or other improper types.
14. Do not use tube extensions on the pump handle.
15. Always wear approved safety glasses/face shields and personal safety equipment. (Everyday eyeglasses
only have impact resistant lenses; they are not safety glasses.)
16. Failure to comply with these warnings may result in serious injury and/or damage to property.
WARNING: This product can expose you to chemicals including titanium dioxide which is known to
the State of California to cause cancer, and lead which is known to the State of California to cause
cancer and birth defects or other reproductive harm. For more information go to http://www.
p65warnings.ca.gov.
WARNING: Some dust, fumes and gases created by power sanding, sawing, grinding, drilling,
welding and other construction activities contain chemicals known to the State of California to cause
cancer and birth defects or other reproductive harm. Some examples of these chemicals are:
lead from lead based paint
crystalline silica from bricks, cement and other masonry products
arsenic and chromium from chemically treated lumber
Your risk of exposure 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 equipment,
such as dust masks that are specifically designed to filter out microscopic particles. For more

6.0 Assembly
Refer to Figure 1 for identification.
1. Use a lifting device, such as a hoist or forklift
with straps, to position machine upright.
2. Bolt the frame brackets to the main frame with
the provided screws and hex nuts. Finger tighten only.
3. The press should be placed within a well-lit
area, upon a level floor, preferably concrete.
Lower the press onto the floor, allowing it to
stabilize on the brackets. Fully tighten the hex
nuts on the frame brackets.
4. The hex filler plug (see parts breakdown: item
#17 for HP-5A; #8A for HP-15A; #8D for HP35A) was installed for shipping purposes.
Remove this and replace it with the provided
vented plug.
5. Place the end of the pump handle into the
handle socket, and secure it with the screw.
7.0 Operation
Refer to Figure 1 for identification.
1. Remove all items from bed plates.
2. Remove table holding pins. (Support the table
frame on the HP-5A.)
3. Raise or lower table frame to desired position,
so that when workpiece is mounted, it will be
close to the ram press head.
Model HP-5A: Raise or lower table frame by
hand.
Models HP-15A,-35A: Rotate crank handle to
raise or lower table frame.
4. Re-insert table holding pins. Pins must be fully
engaged through front and back holes of the
frame.
5. Place workpiece onto bed plates.
Make sure workpiece is
center-loaded and secure before pressing, and
that table holding pins are properly inserted.
Some objects may have a tendency to pop out
or explode under pressure. Exercise proper
precautions.
6. If desired, slide ram assembly laterally (15and 35-ton models only) by mounting the hand
crank onto the lateral shaft and rotating it. Do not attempt to slide ram during operation.
7. The handwheel can be used to rapidly adjust
the ram extension screw into or out of the
plunger.
Note: The length of ram screw extending out
of the piston should be kept as short as
possible. Raise the table rather than extend
the screw to its travel limit.
8. Close valve by rotating release valve handle
clockwise as far as it will turn.
9. Pump the handle to lower the ram until it
makes light contact with workpiece. Align the
workpiece to ensure that desired contact point
is directly beneath the press head. Slowly
pump handle again until load begins to be
applied to workpiece.
10. Remove your hand from workpiece area and
step toward the side of the press (do not stand
directly in front of workpiece). Continue slowly
pumping to complete the operation.
11. When operation is complete, slowly retract ram
by incrementally turning release valve handle
counter-clockwise.
8.0 Maintenance
Keep the press clean, and periodically
lubricate joints and moving parts with light oil.
Inspect the press before each use, for signs of
damage, bent pins, missing or loose bolts,
cracked welds, oil leaks, abnormal operation,
and the like. Make repairs or replacements as
needed before putting the machine back into
service.
Periodically remove filler plug (#17/HP-5A;
#8A/HP-15A; #8D/HP-35A) to check that
hydraulic cylinder is filled with oil. Top off as
needed with good quality hydraulic oil.
Reinsert filler plug.
Flush and replace the oil in the hydraulic
cylinder approximately every 2 years. Refer to
section4.0 Specifications for oil capacity for
your particular model.
