WARNING SYMBOLS AND DEFINITIONS

This is the safety alert symbol. It is used to alert you to potential

personal injury hazards. Obey all safety messages that

follow this symbol to avoid possible injury or death.

Indicates a hazardous situation which, if not avoided,

will result in death or serious injury.

Indicates a hazardous situation which, if not avoided,

could result in death or serious injury.

Indicates a hazardous situation which, if not avoided,

could result in minor or moderate injury.

IMPORTANT SAFETY INFORMATION

WARNING Read all safety warnings and instructions. Failure to heed these markings may result in

personal injury and/or property damage. Save all warnings and instructions for future reference.

The warnings, precautions, and instructions discussed in this manual cannot cover all possible

conditions and situations that may occur. The operator must understand that common sense and

caution are factors, which cannot be built into this product, but must be supplied by the operator.

1. Keep hands away from arbor plates

and press pin during use.

2. Do not move workpiece while compressed.

3. Release load before service or maintenance.

4. Bolt to floor before use.

5. Keep area under arbor plates clear. If arbor

plates rest on obstruction (i.e. bolt, debris,

etc.), it creates an uneven press, causing

excess stress and possible breakage.

6. Avoid off-center loads. Do not operate if

workpiece tilts or binds during compression.

7. STOP and release compression if you suspect

imminent structural failure. If safe, inspect

thoroughly and reposition before proceeding.

8. Do not compress springs or other elastic

objects. They could disengage hazardously.

9. Wear ANSI-approved safety goggles,

heavy-duty work gloves, and steel-toe

work boots during set up and/or use.

10. Keep bystanders out of work area.

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 Release

Valve Screw. Turn the Handle counterclockwise

to open the Release Valve. See Figure G.

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 to adjust the

height of the Press Apron.

2. Position the Press Apron as high as possible

while positioning the workpiece as close as

possible to the ram of the Jack Plate.

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.

Page 9For technical questions, please call 1-888-866-5797.Item 33497

SAFETYOPERATIONMAINTENANCE SETUP

General Operating Instructions

1. Place the item to press between the Arbor Plates.

2. Using the Jack Handle, jack down the Jack

Plate until the ram of the Jack Plate contacts

the workpiece. If you are pressing two

items together, line them up vertically.

3. Continue to operate the Handle

to press the workpiece.

4. When the task is completed, carefully release the

Jack pressure. For safety, remove the Handle,

and use it to slowly turn the Release Valve Screw

on the Jack, allowing the Jack Plate to rise.

WARNING: Stay clear of the rising Jack. The Jack

may rise quickly during the release process.

5. Clean, then store the tool indoors

out of children’s reach.

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 Bottle Jack for

proper operation. If the Bottle Jack appears

not to be working properly, follow instructions

in Bleeding the Bottle Jack on page 8.

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 Bottle Jack fully retracted, unhook

the Springs from the Eye Bolts and remove

the Jack from the Shop Press.

2. Remove the Oil Filler Plug.

3. Tip the 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.

Troubleshooting

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!
