SETUP

Specifications

Assembly

Bolt Shaft Identification Chart

WARNING TO PREVENT SERIOUS INJURY AND DEATH:
The correct bolts must be used during assembly. Carefully compare bolts to Bolt Identification illustration above and the measurements shown in the parts list and assembly diagrams near the end of this manual to make sure that the correct bolts are used in the correct place.

For safety and ease of assembly, use two people to assemble the Shop Crane.

NOTICE: DO NOT TIGHTEN ANY BOLTS UNTIL YOU ARE FULLY FINISHED WITH ASSEMBLY. OTHERWISE PARTS WILL NOT LINE UP PROPERLY.

OPERATION

Operating Instructions

****Read ENTIRE IMPORTANT SAFETY INFORMATION section at beginning of this manual including all text under subheadings therein before set up or use of this product.

Note: Once Assembly is complete, tighten ALL Bolts before initial operation.

Lifting and Lowering

1. Locate the hole on the Boom with a weight limit higher than the weight you will be lifting. For example: Locate the 1/2 TON hole on the Boom for a load that is under 1/2 Ton. See Figure F.

2. Adjust the Boom Extension(24) so the hole farthest from the hook-end aligns with the chosen hole on the Boom(23). Secure into place by inserting the Boom Pin(30) through all aligned holes and securing in place with the R-Pin(14). See Figure F.
   WARNING! Keep clear of the object that is being lifted by the Shop Crane. Be aware of the possibility of a load slipping off the Hook and Chain. An item that falls from the Crane can cause serious injury.

3. Move the Shop Crane so that the Chain / Hook(26) are directly above the Load to be lifted. See Figure F.

4. Securely attach the Chain / Hook(26) to the Load. See Figure F.

5. To raise the Boom, turn the Ram’s Release Valve(7A) fully clockwise (right). Insert the Ram Handle(27) into the Ram(25) and pump (up and down) repeatedly until the Load has been lifted to the desired height. See Figure G.

Note: Fully tighten the Release Valve(7A) or else the Ram(25) may lower or may not be able to reach the full height.
6. To lower the Shop Crane, SLOWLY turn the Release Valve(7A) counterclockwise (left). See Figure G.

Folding the Frame
WARNING! Do not fold the Shop Crane while loaded.

1. Lower the Shop Crane by turning the Release Valve(7A) counterclockwise (left). See Figure H.
2. Remove R-Pins(14) from the front Leg Pins(11). Remove the front Leg Pins(11). Leave rear Leg Pins(11) in. See Figure H.
3. Raise the Legs until they rest against the Ram Handle(27). Insert a front Leg Pin(11) into the middle hole of the Base(25), for each Leg(29), and reinsert R-Pins(14). See Figure H.

Bleeding Instructions
IMPORTANT! Before first use, check for proper hydraulic oil level and thoroughly test the equipment.
If it does not work properly, bleed excess air from its hydraulic system as follows:

1. Open the Release Valve(7A) and lower the Ram(25) completely. See Figure I.
2. Remove Oil Plug(26A) and fill with hydraulic oil (sold separately) to full level. See Figure I.
3. Apply downward pressure to the Boom(23) and Pump the Ram Handle(27) quickly several times. See Figure I.
4. Check the Oil Fill Hole and, if necessary, top off the Oil Fill Hole with hydraulic oil. See Figure I.
5. Replace the Oil Plug(26A) and close the Release Valve(7A). See Figure I.

6. Test the equipment several times for proper operation before attempting to lift a load. If, after bleeding, the equipment still does not appear to be working properly, do not use the equipment until it has been repaired by a qualified service technician.

Maintenance and Servicing

****Procedures not specifically explained in this manual must be performed only by a qualified technician.

WARNING TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
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 tool. Check for:
   • 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, thoroughly test the Ram(25) for proper operation prior to its actual use.
   If the Ram(25) appears to not be working properly, follow Bleeding instructions on page 8.

3. Change the hydraulic oil at least once every three years:
   a. With the Ram(25) fully lowered, remove the Oil Plug(26A) on the side of the Oil Tank(25A).
   b. Tip the Ram(25) to allow the old hydraulic oil to drain out of the Oil Tank(25A) completely, and dispose of the old hydraulic oil in accordance with local regulations.
   c. With the Ram(25) upright, completely fill the Oil Tank(25A) with a high quality hydraulic oil (not included) until the oil just begins to run out of the Oil Fill Hole.
   d. Open the Release Valve(7A) and pump the Ram Handle(27) to bleed air from the system.
   e. Reinstall the Oil Plug(26A).

4. Wipe dry with a clean cloth. Then, store the Shop Crane in a safe, dry location out of reach of children and other non-authorized people.

Troubleshooting

WARNING

TO PREVENT SERIOUS INJURY: Use caution when troubleshooting malfunctioning ram. Stay clear of supported load. Completely resolve all problems before use.

If solutions presented in Troubleshooting guide do not solve the problem, have a qualified technician inspect and
repair ram before use. After ram is repaired: Test it carefully without a load by raising and lowering it fully, checking for proper operation, BEFORE RETURNING RAM TO OPERATION.

DO NOT USE A DAMAGED OR MALFUNCTIONING RAM!
