6. Operating Instructions

6.1 Lifting a Vehicle

1. Prepare the Vehicle: Park the vehicle on a firm, level surface. Engage the parking brake and chock the wheels that will remain on the ground.
2. Position the Jack: Roll the jack under the vehicle, positioning the saddle directly under the designated lifting point as specified by the vehicle manufacturer. The long handle allows for easier positioning under vehicles with long overhangs.
3. Connect Air Supply: Ensure the air hose is securely connected to the jack and the air compressor is providing the recommended pressure (90-145 psi).
4. Initiate Lift: To lift the vehicle, activate the air control lever on the handle. The jack will begin to raise the load. Monitor the lifting process carefully.
5. Secure the Load: Once the desired height is reached, immediately place appropriately rated jack stands under the vehicle's frame or axle at the manufacturer's recommended support points.
6. Lower Jack Slightly: Slowly lower the jack until the vehicle rests securely on the jack stands. The jack should remain in contact with the vehicle's lifting point, but not bear the full load.

1. Raise Slightly: Lift the vehicle slightly off the jack stands using the jack.
2. Remove Jack Stands: Carefully remove the jack stands from under the vehicle.
3. Lower the Jack: Slowly turn the release knob on top of the handle counter-clockwise to lower the jack. Control the descent rate to ensure a smooth and safe lowering process.
4. Remove Jack: Once the vehicle is fully on the ground, remove the jack.

7. Maintenance

Regular maintenance is essential for the longevity and safe operation of your MOTOOS Air Hydraulic Floor Jack.

• Daily Inspection: Before each use, inspect the jack for any signs of damage, wear, or leaks. Check the air hose for cracks or fraying.
• Hydraulic Fluid: Periodically check the hydraulic fluid level. If low, replenish with a high-quality hydraulic jack oil. Refer to the jack's specific instructions for fluid type and filling procedure.
• Lubrication: Lubricate moving parts, such as wheels and pivot points, with general-purpose grease as needed.
• Cleaning: Keep the jack clean from dirt, grease, and oil. A clean jack is easier to inspect for potential issues.
