- Handle: Used for pumping the jack and controlling the release valve.
- Release Valve: Controls the lowering speed of the jack.
- Wheels: For maneuvering the jack.
- Chassis: The main frame of the jack.
3. Setup and Preparation
- Unpacking: Carefully remove the jack from its packaging. Inspect for any signs of damage during transit.
- Handle Assembly: Insert the handle into the handle socket. Secure it according to the instructions provided with the jack (typically involves aligning a pin or tightening a screw).
- Purging Air (Bleeding): Before first use, or if the jack has been stored for a long period, it may be necessary to purge air from the hydraulic system.
- Turn the release valve counter-clockwise to fully open it.
- Pump the handle several times to expel any air.
- Turn the release valve clockwise to close it.
- Pre-Use Check: Ensure all bolts and fittings are tight. Check for any hydraulic fluid leaks.
4. Operating Instructions
4.1. Lifting a Vehicle
- Preparation:
- Park the vehicle on a firm, level surface.
- Engage the parking brake and place the transmission in "Park" (automatic) or a low gear (manual).
- Place wheel chocks on the wheels that will remain on the ground.
- Positioning the Jack: Locate the vehicle manufacturer's recommended lifting points. Position the jack so the saddle is directly under the lifting point. Ensure the jack is stable and not on an incline.
- Closing the Release Valve: Turn the handle clockwise until the release valve is fully closed. Do not overtighten.
- Lifting: Pump the handle up and down to raise the saddle. The Super Rocket Lift feature will quickly bring the saddle into contact with the lifting point. Continue pumping until the vehicle is raised to the desired height.
- Secure with Jack Stands: Immediately place appropriately rated jack stands under the vehicle's designated support points. Slowly lower the vehicle onto the jack stands by gently turning the release valve counter-clockwise. Ensure the vehicle is securely resting on the jack stands before performing any work.
4.2. Lowering a Vehicle
- Raise Slightly: If the vehicle is on jack stands, pump the jack handle a few times to lift the vehicle slightly off the jack stands.
- Remove Jack Stands: Carefully remove the jack stands from under the vehicle.
- Lowering: Slowly turn the handle counter-clockwise to open the release valve. The vehicle will begin to lower. Control the lowering speed by adjusting how much you open the valve.
- Full Lowering: Continue to lower the vehicle until it is fully on the ground. Remove the jack from under the vehicle.
5. Maintenance
- Lubrication: Periodically lubricate all moving parts with light machine oil.
- Hydraulic Fluid: Check the hydraulic fluid level regularly. If low, top up with a high-quality hydraulic jack oil. Do not use brake fluid or other fluids.
- Cleaning: Keep the jack clean and free from dirt, grease, and corrosive materials.
- Storage: Store the jack in a dry, clean area with the ram fully retracted.
- Inspection: Before each use, inspect the jack for any signs of damage, wear, or leaks. If any issues are found, do not use the jack and consult a qualified service technician.
