2. Safety Information

Read all instructions carefully before using the scale. Failure to follow these instructions may result in injury or damage to the equipment.

• Maximum Capacity: Do not exceed the maximum weighing capacity of 2200 lbs (1000 kg). Overloading can damage the scale and create a safety hazard.
• Secure Attachment: Always ensure the scale is securely attached to a stable overhead support and that the load is properly secured to the hook before weighing.
• Inspect Before Use: Before each use, inspect the shackle, hook, and scale body for any signs of wear, damage, or deformation. Do not use if any damage is found.
• Remote Control: Use the remote control for operation whenever possible to maintain a safe distance from heavy loads.
• Battery Safety: Ensure batteries are inserted correctly. Do not mix old and new batteries or different types of batteries. Dispose of used batteries responsibly.
• Environmental Conditions: Avoid using the scale in extreme temperatures, high humidity, or corrosive environments unless specifically rated for such conditions.
• Children and Unauthorized Personnel: Keep the scale out of reach of children and ensure only trained personnel operate the device.

6. Operating Instructions

6.1 Power On/Off

• To Power On: Press the ON/OFF button on the scale or the remote control. The display will light up and show the battery voltage before settling at zero.
• To Power Off: Press and hold the ON/OFF button on the scale or the remote control until the display turns off.

6.2 Unit Conversion (lb/kg)

The scale supports weighing in both pounds (lb) and kilograms (kg).

• Press the UNIT button on the remote control to switch between 'lb' and 'kg'.
• The scale will retain the last selected unit even after being powered off and on again.

6.3 Tare / Zero Function

• Zero: With no load on the hook, press the ZERO button to set the display to zero. This is useful for ensuring accuracy before weighing.
• Tare: To weigh an item in a container, first hang the empty container on the hook. Press the TARE button. The display will reset to zero. Then, add the item to the container to weigh only the item's net weight.

6.4 Weighing Procedure

1. Ensure the scale is powered on and displays '0.0' in the desired unit (lb or kg). Use the ZERO button if necessary.
2. Carefully attach the item to be weighed to the scale's hook. Ensure the load is stable and not swinging.
3. Read the weight displayed on the LCD screen.
4. Remove the load from the hook.

6.5 Overload Warning

If the load exceeds the maximum capacity, the scale will display an overload warning (e.g., "O-L"). Immediately remove the excess weight to prevent damage to the scale.

7. Maintenance

• Cleaning: Wipe the scale with a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water.
• Battery Replacement: When the battery voltage display indicates low power (below 3.5V), replace all AA batteries in the scale and AAA batteries in the remote control with new 1.5V batteries.
• Storage: Store the scale in a dry, cool place away from direct sunlight and extreme temperatures. If storing for an extended period, remove all batteries to prevent leakage.
• Inspection: Regularly inspect the shackle, hook, and load-bearing points for any signs of wear, cracks, or corrosion. Replace damaged components immediately.
