2. ข้อมูลด้านความปลอดภัย

คำเตือน: การไม่ปฏิบัติตามคำแนะนำด้านความปลอดภัยเหล่านี้อาจส่งผลให้ได้รับบาดเจ็บสาหัสหรือเสียชีวิตได้

• 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.
• ห้ามดัดแปลงแจ็คในทางใดทางหนึ่ง
• Store the jack in a clean, dry place when not in use.

3. Components and Identification

Figure 3.1: SIMPLEX RJ84A Steel Mechanical Ratchet Jack

The image above displays the SIMPLEX RJ84A steel mechanical ratchet jack, presented from a three-quarter front view. The jack is finished in a distinctive yellow color, indicating its robust industrial design. Key components visible include a sturdy, broad base for stability, a vertical lifting column, and a top saddle designed to securely cradle loads. On the side, a prominent lever mechanism is integrated, which is used for both lifting and lowering operations. A warning label is clearly affixed to the side of the jack, which, upon closer inspection, indicates 'SIMPLEX 5 TON CAPACITY', reinforcing the jack's maximum load rating and brand identity.

ส่วนประกอบหลัก:

• Top Saddle: The primary lifting point for loads.
• Lifting Toe: A lower lifting point for loads with low clearance.
• Operating Lever Socket: Where the operating lever is inserted.
• กลไกแรตเช็ต: Internal mechanism that allows incremental lifting and controlled lowering.
• ฐาน: Provides stability for the jack during operation.
• Reversing Lever: Used to switch between lifting and lowering modes.

4. การตั้งค่า

1. Inspect the Jack: Before each use, visually inspect the jack for any signs of damage, cracks, bends, or excessive wear. Ensure all moving parts operate smoothly. Do not use if damaged.
2. เตรียมพื้นที่ทำงาน: Ensure the work area is well-lit, clear of obstructions, and on a firm, level, and stable surface.
3. ตำแหน่งแม่แรง: Place the jack directly under the load's lifting point. Ensure the load is centered on either the top saddle or the lifting toe, depending on the application.
4. Insert Operating Lever: Insert the appropriate operating lever (not included with all models) firmly into the operating lever socket.

5. คู่มือการใช้งาน

5.1. การยกของหนัก

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. การลดภาระ

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. การบำรุงรักษา

• การหล่อลื่น: Periodically lubricate all moving parts, including the ratchet mechanism, lifting screw (if applicable), and pivot points, with a good quality general-purpose grease or oil.
• การทำความสะอาด: Keep the jack clean and free of dirt, debris, and corrosive materials. Wipe down the exterior after each use.
• การตรวจสอบ: Regularly inspect the jack for any signs of wear, damage, or loose fasteners. Pay close attention to the lifting points (saddle and toe) and the integrity of the base.
• พื้นที่จัดเก็บ: Store the jack in a dry, protected area to prevent rust and corrosion. Ensure it is in a stable position where it cannot fall.
• บริการระดับมืออาชีพ: If any damage or malfunction is detected that cannot be resolved with basic maintenance, do not attempt to repair it yourself. Contact a qualified service technician or the manufacturer for repair.
