2. คำแนะนำด้านความปลอดภัย

Always prioritize safety when operating hydraulic lifting equipment. Failure to follow these instructions may result in serious injury or property damage.

• อ่านคู่มือ: Before operating the jack, thoroughly read and understand all instructions and warnings in this manual.
• ความจุสูงสุด: Never exceed the maximum rated lifting capacity of 2 tons (2000 kg).
• พื้นผิวที่มั่นคง: Use the jack only on a hard, level, and stable surface capable of supporting the load. Avoid soft ground or uneven surfaces.
• การใช้ขาตั้งแม่แรง: After lifting a vehicle, always support it immediately with appropriate jack stands before performing any work. Never rely solely on the hydraulic jack for support.
• เคลียร์สต๊อก : Keep hands, feet, and other body parts clear of moving parts and the area under the lifted load.
• ความเสถียรของยานพาหนะ: Ensure the vehicle is in park (or gear for manual transmission), the parking brake is engaged, and the wheels not being lifted are chocked.
• การตรวจสอบปกติ: Inspect the jack for damage, leaks, or wear before each use. Do not use a damaged jack.
• การจัดเก็บที่เหมาะสม: Store the jack in a clean, dry place, fully lowered, when not in use.

4. การตั้งค่า

โปรดทำตามขั้นตอนเหล่านี้เพื่อตั้งค่าเบื้องต้นก่อนใช้งานครั้งแรก

1. จับประกอบ: Insert the smaller section of the operating handle into the larger section, ensuring it clicks securely into place. Then, insert the assembled handle into the jack's pump mechanism.
2. การไล่ลมออกจากระบบไฮดรอลิก (การใช้งานครั้งแรก): To ensure proper operation, it is recommended to bleed any air from the hydraulic system before first use. To do this, open the release valve by turning the handle counter-clockwise. Pump the handle several times to its full extent. Close the release valve by turning the handle clockwise. The jack should now be ready for use.

5. คู่มือการใช้งาน

ปฏิบัติตามคำแนะนำด้านความปลอดภัยก่อนและระหว่างการใช้งานเสมอ

1. เตรียมยานพาหนะ: Park the vehicle on a hard, level surface. Engage the parking brake and place the transmission in park (or first gear for manual). Chock the wheels that will remain on the ground.
2. ตำแหน่งแม่แรง: Locate the manufacturer-recommended lifting points on your vehicle. Position the jack saddle directly under the lifting point. Ensure the jack is stable and not at an angle.
3. ยกตัวรถขึ้น: Close the release valve by turning the operating handle clockwise until it is firm. Pump the operating handle up and down to raise the jack saddle. Continue pumping until the vehicle is lifted to the desired height. Do not lift higher than necessary.
4. ยึดให้แน่นด้วยขาตั้งแม่แรง: Immediately place appropriately rated jack stands under the vehicle's designated support points. Slowly lower the vehicle onto the jack stands by gradually turning the operating handle counter-clockwise to open the release valve. Once the vehicle is securely resting on the jack stands, remove the hydraulic jack.
5. ลดระดับรถลง: When work is complete, carefully raise the vehicle slightly with the hydraulic jack to remove the jack stands. Once jack stands are removed, slowly open the release valve by turning the operating handle counter-clockwise to lower the vehicle completely to the ground. Remove the jack once the vehicle is fully lowered.

6. การบำรุงรักษา

การบำรุงรักษาอย่างสม่ำเสมอจะช่วยให้แม่แรงไฮดรอลิกของคุณมีอายุการใช้งานยาวนานและใช้งานได้อย่างปลอดภัย

• น้ำมันไฮดรอลิก: Check the hydraulic fluid level periodically. If low, refill with a high-quality hydraulic jack oil. Do not use brake fluid or other non-specified fluids.
• การหล่อลื่น: Lubricate all moving parts, such as pivot points and wheels, with light machine oil as needed.
• การทำความสะอาด: Keep the jack clean and free from dirt, grease, and debris. Wipe down the ram and pump mechanism after each use.
• พื้นที่จัดเก็บ: Store the jack in a dry, protected area, fully lowered, to prevent corrosion and damage.

7 การแก้ไขปัญหา
