TRESKO 2.5 Ton Hydraulic Jack User Manual

1. Important Safety Information

Read and understand all instructions and warnings before using this hydraulic jack. Failure to follow these instructions may result in property damage, personal injury, or death. Keep this manual for future reference.

• Maximum Load Capacity: Never exceed the maximum load capacity of 2.5 tons (2500 kg).
• Stable Surface: Always use the jack on a hard, level, and stable surface. Avoid uneven ground or soft surfaces.
• Use Jack Stands: Never work under a vehicle supported only by a hydraulic jack. Always use appropriate jack stands to support the vehicle after lifting.
• Vehicle Stability: Ensure the vehicle is in park (P), the parking brake is engaged, and the wheels not being lifted are chocked to prevent movement.
• Proper Positioning: Position the jack only on the vehicle manufacturer's recommended lifting points. Use the provided rubber pads to prevent damage to the vehicle's chassis.
• Clear Area: Keep hands, feet, and other body parts clear of the jack and vehicle during lifting and lowering operations.
• Fluid Leaks: If hydraulic fluid leaks, discontinue use immediately and consult a qualified technician.
• Children and Bystanders: Keep children and unauthorized persons away from the work area.

4. Setup

4.1 Handle Assembly

1. Insert the two parts of the lifting bar (handle) together.
2. Insert the assembled handle into the handle socket on the jack. Ensure it is securely seated.

4.2 Bleeding the Hydraulic System (Initial Use)

Before first use, or if the jack has been stored for a long time, it is recommended to bleed any air from the hydraulic system:

1. Turn the release valve (located at the base of the handle socket) counter-clockwise one full turn to open it.
2. Pump the handle 10-15 full strokes to expel any air.
3. Turn the release valve clockwise until it is firmly closed.
4. The jack is now ready for use.

5. Operating Instructions

5.1 Preparation

1. Park the vehicle on a hard, level surface.
2. Engage the parking brake and place the transmission in 'Park' (automatic) or a low gear (manual).
3. Place wheel chocks on the wheels that will remain on the ground to prevent accidental movement.
4. Ensure the area around the vehicle is clear of obstructions and bystanders.

5.2 Lifting a Vehicle

1. Position the jack directly under the vehicle's designated lifting point. Refer to your vehicle's owner's manual for specific lifting points.
2. Place one of the provided rubber pads on the jack's saddle to protect the vehicle's chassis. Use the appropriate pad for your vehicle type (e.g., grooved pad for older vehicles or flat pad for modern vehicles without specific lifting points).
3. Ensure the release valve is fully closed by turning the handle clockwise.
4. Pump the handle up and down to raise the jack. Continue pumping until the vehicle is lifted to the desired height.
5. Once the vehicle is lifted, immediately place appropriately rated jack stands under the vehicle's frame or axle, adjacent to the jack.
6. 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.

5.3 Lowering a Vehicle

1. Ensure all tools and personnel are clear from under the vehicle.
2. Raise the vehicle slightly with the hydraulic jack to remove the jack stands.
3. Carefully remove the jack stands.
4. Slowly turn the release valve counter-clockwise to lower the vehicle in a controlled manner. Do not open the valve too quickly.
5. Once the vehicle is fully lowered, remove the hydraulic jack.

6. Maintenance

6.1 Cleaning

• Regularly clean the jack with a damp cloth to remove dirt, grease, and debris.
• Do not use harsh chemicals or solvents that could damage the paint or seals.
• The jack features an anti-scratch and anti-corrosion coating for durability.

6.2 Hydraulic Fluid

• Check the hydraulic fluid level periodically. To do this, ensure the jack is fully lowered and on a level surface.
• Remove the oil filler plug. The fluid level should be just below the filler hole.
• If necessary, top up with a high-quality hydraulic jack oil. Do not overfill.
• Never use brake fluid, alcohol, glycerin, detergent, or dirty oil, as this can damage the seals and internal components.

6.3 Storage

• Store the jack in its transport case in a dry, clean, and safe environment.
• Always store the jack in the fully lowered position to relieve pressure on the hydraulic system.
