4. Setup and Assembly

4.1 Transmission Jack Assembly (Model 7796)

1. Unpack all components and verify against the parts list.
2. Attach the caster wheels to the base of the jack. Ensure all bolts are securely tightened.
3. Insert the hydraulic cylinder and column into the base.
4. Attach the universal saddle to the top of the hydraulic cylinder.
5. Connect the pump handle/foot pedal assembly.
6. Bleed the hydraulic system according to the instructions in the Maintenance section to remove any air.

4.2 Fuel Tank Adapter Assembly (Model 7706)

1. Attach the adapter frame to the universal saddle of the transmission jack. The adapter comes with a universal adapter plate for compatibility.
2. Install the foam support pads onto the adapter frame. These pads can be adjusted for height, width, and length.
3. Ensure the ground wire assembly is accessible and ready for connection.

5. Operating Instructions

5.1 Operating the Transmission Jack (Model 7796)

1. Preparation: Ensure the vehicle is securely lifted on a hoist or jack stands and is stable. The transmission jack should be on a flat, level, and stable surface. Unlock the caster wheels for maneuverability.
2. Positioning: Roll the transmission jack under the vehicle and position the universal saddle directly beneath the transmission or component to be removed/installed.
3. Adjusting Saddle: Adjust the four ratcheting arms of the universal saddle to securely cradle the transmission pan. Ensure the load is balanced.
4. Lifting (Hydraulic): Close the release valve by turning it clockwise. Pump the foot pedal or handle to raise the saddle to the desired height.
5. Lifting (Air): Connect an air hose to the air inlet. The jack will raise as air pressure is applied.
6. Lowering: Slowly open the release valve by turning it counter-clockwise to lower the saddle. Control the lowering speed carefully.
7. Securing: Once the jack is in position and supporting the load, engage the locking feature on the caster wheels to prevent unintended movement.

5.2 Operating the Fuel Tank Adapter (Model 7706)

1. Attachment: Ensure the fuel tank adapter is securely mounted to the transmission jack's universal saddle.
2. Positioning: Maneuver the jack with the adapter under the fuel tank.
3. Adjusting Support Pads: Adjust the height, width, and length of the foam support pads to conform to the shape of the fuel tank, ensuring maximum contact and stability.
4. Ground Wire: For metal fuel tanks, connect the ground wire assembly to a suitable grounding point on the vehicle chassis to prevent static discharge.
5. Securing Tank: Use the two 8-foot tie-down straps to firmly secure the fuel tank to the adapter. Ensure the straps are tight and the tank cannot shift during lifting or lowering.
6. Lifting/Lowering: Use the transmission jack's hydraulic or air lift mechanism to carefully raise or lower the fuel tank. Maintain control at all times.

6. Maintenance

Regular maintenance is crucial for the longevity and safe operation of your Sunex equipment.

• Hydraulic Fluid: Check the hydraulic fluid level periodically. Use only high-quality hydraulic jack oil. Refer to the jack's specific markings for fluid type and capacity.
• Bleeding Air: If the jack does not lift smoothly or reaches full height, air may be trapped in the hydraulic system. To bleed, open the release valve, remove the oil filler plug, pump the handle several times, then close the release valve and replace the plug.
• Cleaning: Keep the jack and adapter clean and free of dirt, grease, and debris. Wipe down surfaces with a clean cloth.
• Inspection: Before each use, inspect all components for signs of wear, damage, or corrosion. Check hydraulic hoses for leaks, casters for smooth operation, and the saddle/pads for integrity.
• Lubrication: Lubricate pivot points and moving parts as needed with light machine oil.
• Storage: Store the jack and adapter in a clean, dry area when not in use. Lower the jack completely before storage.
