• Always read and understand the entire instruction manual before operating the jack.
• Do not exceed the rated capacity of 5 tons. Overloading can cause jack failure and severe injury.
• Ensure the jack is placed on a firm, level, and stable surface capable of supporting the load.
• Center the load on the jack's saddle or toe to prevent slipping.
• Never work under a load supported only by a jack. Always use appropriate jack stands or cribbing to secure the load after lifting.
• Keep hands and feet clear of moving parts and the load during operation.
• Inspect the jack for damage, wear, or missing parts before each use. Do not use a damaged jack.
• Use only the specified operating lever or handle. Do not use extensions or cheater bars that could overstress the jack.
• Ensure the lowering mechanism is fully engaged before attempting to lower a load.

5.1. Lifting a Load

1. Ensure the reversing lever is set to the 'LIFT' position.
2. Operate the lever with smooth, full strokes. Each downward stroke of the lever will raise the load incrementally.
3. Continue operating the lever until the load reaches the desired height.
4. Once the load is lifted, immediately place appropriate jack stands or cribbing under the load for support. Never rely solely on the jack to support a lifted load.

5.2. Lowering a Load

1. Ensure the area beneath the load is clear.
2. If jack stands or cribbing were used, carefully remove them once the load is ready to be lowered onto the jack.
3. Set the reversing lever to the 'LOWER' position.
4. Operate the lever with smooth, controlled strokes. Each downward stroke will incrementally lower the load.
5. Lower the load slowly and carefully until it is fully supported by the ground or its intended resting surface.

6. ບໍາລຸງຮັກສາ
