Operation 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. Maintenance 1. Keep hands away from Arbor Plates and Press Pin during use. 6. Avoid off-center loads. Do not operate if workpiece tilts or binds during compression. 2. Do not move workpiece while compressed. 7. STOP and release compression if you suspect imminent structural failure. If safe, inspect thoroughly and reposition before proceeding. 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. 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.

Hook the Springs (7) into the Eye Bolts (8) to secure the Bottle Jack/Jack Plate in place. Eye Bolts (8) Figure F Mounting to the Floor Setup 1. To mount the Shop Press, with assistance, move the unit to the location where it is to be used. If needed, drill four 1/2" diameter mounting holes in the feet 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. 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. 3. Set the Shop Press back to the location where it is to be used, and align the four 1/2" diameter mounting holes in its feet with the four pre-drilled 1/2" holes in the concrete or wood. Then 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.

Page 7 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. Safety Bleeding the Ram IMPORTANT! Before first use, check for proper hydraulic fluid level in the Ram. Then thoroughly test the Ram for proper operation prior to its actual use. If the Ram appears not to be working properly, it may be necessary to bleed its hydraulic system of excess air. To bleed the Ram: 1. Remove the Fluid Filler Plug. Insert the slot on the lower portion of the Handle over the Valve Release Screw. Turn the Handle counterclockwise to close the Valve Release Screw. 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 Fluid Fill Hole and, if necessary, top off the Fluid Fill Hole with hydraulic fluid. 4. Replace the Fluid Filler Plug. 5. Test the Ram several times before putting into use. If, after purging, the Ram still does not appear to be working properly, do not use the Ram until it has been repaired by a qualified service technician. Setup Handle (15) Elevating Screw (some models) Plunger/ Fulcrum Saddle Fluid Fill Hole Operation Valve Release Screw Fluid Filler Plug Figure G Tool Set Up 1. Use the Support Pins (6) to adjust the height of the Press Apron (5). 2. Position the Press Apron as high as possible while positioning the workpiece as close as possible to the ram of the Ram Plate (2 ). 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. Workpeice Set Up Maintenance 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 8 For technical questions, please call 1-888-866-5797. Item 32879 1. Place the item to press between the Arbor Plates (3). 2. Using the Ram Handle (15), jack down the Ram Plate until the ram of the Ram Plate contacts your 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 Ram pressure. For safety, remove the Handle, and use it to slowly turn the Valve Release Screw on the Ram, allowing the Ram Plate to rise. WARNING: Stay clear of the rising Ram. The Ram may rise quickly during the release process. 5. Clean, then store the tool indoors out of children’s reach. Safety General Operating Instructions Maintenance and Servicing Procedures not specifically explained in this manual must be performed only by a qualified technician. Setup TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Turn the Power Switch of the tool off before performing any procedure in this section. 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 • loose hardware, • misalignment or binding of moving parts, • cracked or broken parts, and • any other condition that may affect its safe operation. 2. BEFORE EACH USE, test the Ram (5) for proper operation. If the Ram appears not to be working properly, follow instructions in Bleeding the Ram on page 8. 3. AFTER USE, wipe external surfaces of the tool with clean cloth. Hydraulic Fluid 1. With the Ram fully lowered, unhook the Springs from the Eye Bolts and remove the Ram from the Shop Press. 2. Remove the Fluid Filler Plug. 3. Tip the Ram to allow the old hydraulic fluid to drain out of the unit completely, and dispose of the old hydraulic fluid in accordance with local regulations. Item 32879 4. Completely fill the unit with a high quality hydraulic fluid (not included) until the fluid just begins to run out of the Fluid Fill Hole. 5. Reinstall the Fluid Filler Plug. 6. Clean with a clean cloth using a detergent or mild solvent. 7. Replace the Ram onto the Shop Press (See Hang the Ram on page 6). For technical questions, please call 1-888-866-5797. Maintenance Change the hydraulic fluid at least once every three years. To change the hydraulic fluid: Operation 1. BEFORE EACH USE, inspect the general condition of the tool. Check for: Page 9 Troubleshooting Safety TO PREVENT SERIOUS INJURY: Use caution when troubleshooting a malfunctioning Ram. 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 Ram before use. After the Ram is repaired: Test it carefully without a load by raising it and lowering it fully, checking for proper operation, BEFORE RETURNING THE RAM TO OPERATION. DO NOT USE A DAMAGED OR MALFUNCTIONING RAM! POSSIBLE SYMPTOMS Ram will not function at its weight capacity Saddle lowers under load X X Setup X Pump stroke feels spongy Handle Saddle will moves not lift all up when the way Ram is under load Check that Release Valve is closed fully. X X X X PROBABLE SOLUTION Fluid (Make certain that the Ram is not leaking supporting a load while attempting a from filler solution.) plug X Operation X Valves may be blocked and may not close fully. To flush the valves: 1. Lower the Saddle and securely close the Release Valve. 2. Manually lift the saddle several inches. 3. Open the release valve and force the saddle down as quickly as possible. Ram may be low on fluid. Check the fluid level and refill if needed. Ram may require bleeding - see instructions on page 8. Unit may have too much hydraulic fluid inside, check fluid level and adjust if needed.
