IMpORTANT SAFETy INFORMATION
Shop press Overall Safety Warnings
1. Study, understand, and follow all instructions
before operating the device.
2. Do not exceed rated capacity.
3. Keep hands, arms, feet and legs
out of the work area.
4. Wear eye protection.
5. Avoid off-center loads.
6. Failure to heed and understand these
instructions and warnings may result in
personal injury and/or property damage.
7. The press shall be installed and operated
in accordance with federal (OSHA),
state, and local safety standards.
8. Use appropriate guarding to contain any pieces
that may break or fly apart when applying force.
9. When attachments and adapters are used,
the rated capacity of the system shall be
no greater than the rated capacity of the
lowest-rated component or combination of
components that make up the system.
10. Operators and observers shall wear eye protection
that meets ANSI/ISEA Z887.1 and OSHA standards.
11. Prior to use, make sure the press
is securely anchored.
12. Verify lift cables are slack before

Mounting to the Floor
1. With assistance, move the Shop Press to the
location where it is to be mounted. If needed, drill
four 1/2″ diameter mounting holes in the Base
Supports and use as a template to mark the spots
where four 1/2″ diameter holes will be drilled in the
concrete or wood floor. Check for any hidden wiring
or cables and adjust the location for the holes as
needed. Then, temporarily set the Shop Press aside.
2. For concrete floors use a masonry drill bit
to drill the four 1/2″ diameter holes
(about 3″– 4″ deep) into the concrete.
Make sure to blow out the concrete dust
from the drilled holes. Insert lag screw
anchors (not included) into the holes.
3. Move the Shop Press back to the location where it
is to be mounted, and align the four 1/2″ diameter
mounting holes in the Base Supports with the four
pre-drilled 1/2″ holes in the concrete or wood.
Use four minimum 3″ long, 1/2″ diameter concrete
anchor bolts or lag bolts (not included) to secure
the Shop Press to the concrete or wood floor.

Operating Instructions
Read the ENTIRE IMpORTANT SAFETy INFORMATION section at the beginning of this manual
including all text under subheadings therein before set up or use of this product.
Bleeding the Bottle Jack
IMpORTANT! Before first use, check for proper
hydraulic oil level in the Jack. Then thoroughly
test the Jack for proper operation prior to its
actual use. If the Jack appears not to be working
properly, it may be necessary to bleed its hydraulic
system of excess air. To bleed the Bottle Jack:
1. Remove the Oil Filler Plug. Insert the slot
on the lower portion of the Jack Handle over
the Valve Release Screw. Turn the Handle
counterclockwise to open the Valve Release Screw.
2. Insert the Handle into the Plunger/Fulcrum
Assembly. Apply pressure to the Saddle, and
pump the Handle quickly several times.
3. Check the Oil Fill Hole and, if necessary,
top off the Oil Fill Hole with hydraulic oil.
4. Replace the Oil Filler Plug.
5. Place the slot on the Jack Handle over
the Release Valve Screw. Turn the Handle
clockwise to close the Release Valve.
6. Test the Jack several times before putting into use.
If, after purging, the Jack still does not appear to
be working properly, do not use the Jack until it has
been repaired by a qualified service technician.
Tool Set Up
1. Use the Support Pins (10) to adjust the
height of the Press Apron (19).
2. The Press Apron should be in the highest
position possible with the workpiece as close
as possible to the ram of the Jack Plate (17).
WARNING: Keep area under Arbor Plates
clear of stray bolts or debris. Such items
create an uneven surface which can cause
the Arbor Plates to break under pressure.
Workpiece Set Up
WARNING: When pressing two items together, the items must be lined up vertically.
If not, one item may forcefully eject sideways from the unit.
General Operating Instructions
1. Place the item to press on the Arbor
Plates (18). Turn the Arbor Plates to support
the stationary part of the workpiece.
2. Using the Jack Handle (23), jack down the Jack
Plate until the ram of the Jack Plate contacts the
workpiece. When pressing two items together, make
sure that they are in vertical alignment. Continue to
operate the Jack Handle to press the work piece.
3. After the task is completed, be careful when
releasing Jack pressure. For safety, remove
the Jack Handle, then use the Handle to
slowly turn the Valve Release Screw on the
Jack, allowing the Jack Plate to rise.
4. Clean, then store the tool indoors
out of children’s reach.
WARNING! TO pREVENT SERIOUS
INJURy: During the release process the
Jack may rise quickly. Stay clear.

Maintenance and Servicing
procedures not specifically explained in this manual must
be performed only by a qualified technician.
TO pREVENT SERIOUS INJURy FROM TOOL FAILURE:
Do not use damaged equipment. If abnormal noise or vibration occurs, have the
problem corrected before further use.
cleaning, Maintenance, and Lubrication
1. BEFORE EAcH USE, inspect the general condition
of the Shop Press and Bottle Jack. Check for:
• loose hardware
• cracked, bent or broken parts
• loose or missing parts
• misalignment or binding of moving parts
• any other condition that may
affect its safe operation.
2. BEFORE EAcH USE, test the Jack for proper
operation. If the Bottle Jack appears not to
be working properly, follow instructions in
Bleeding the Bottle Jack on page .
3. AFTER USE, wipe external surfaces
of the tool with clean cloth.
Hydraulic Oil
Change the hydraulic oil at least once every
three years. To change the hydraulic oil:
1. With the Jack fully lowered, unhook the Springs (5)
from the Eye Bolts (8), remove two bolts (7), and
remove the Jack from the Jack Plate (17).
2. Remove the Oil Filler Plug.
3. Tip the Bottle Jack to allow the old hydraulic oil to
drain out of the unit completely, and dispose of the
old hydraulic oil in accordance with local regulations.
4. Completely fill the unit with a high quality
hydraulic oil (not included) until the oil just
begins to run out of the Oil Fill Hole.
5. Reinstall the Oil Filler Plug.
6. Clean with a clean cloth using a
detergent or mild solvent.
7. Replace the Bottle Jack onto the Shop Press.
Refer to Hang the Bottle Jack on page 6.

TO pREVENT SERIOUS INJURy:
Use caution when troubleshooting a malfunctioning jack.
completely resolve all problems before use. If the solutions presented in the
Troubleshooting guide do not solve the problem, have a qualified technician inspect and repair the jack before use.
After the jack is repaired: Test it carefully without a load by raising it and lowering it fully, checking for
proper operation, BEFORE RETURNING THE JAcK TO OpERATION.
DO NOT USE A DAMAGED OR MALFUNcTIONING JAcK!
