2. Safety Information
- Always ensure the scale is securely mounted and the load is properly attached to the hook before weighing.
- Do not exceed the maximum weighing capacity of 6600 lbs (3000 kg). Overloading can cause damage to the scale and potential injury.
- Avoid sudden impacts or dropping the scale.
- Do not attempt to disassemble or repair the scale yourself. Contact qualified personnel for service.
- Keep the remote control and scale away from water and extreme temperatures.
- Ensure batteries are inserted with correct polarity. Remove batteries if the scale will not be used for an extended period.
3. Product Components
The VEVOR OCS-D Crane Scale package includes the following items:
- 1 x Digital Crane Scale
- 1 x Remote Control
- 1 x User Manual (This document)
- 2 x 1.5V AA Batteries (for remote control)
- 1 x Power Adapter (for scale charging)

4. Setup
4.1. Battery Installation (Remote Control)
- Locate the battery compartment on the back of the remote control.
- Open the battery cover.
- Insert two 1.5V AA batteries, ensuring correct polarity (+/-).
- Close the battery cover securely.
4.2. Charging the Crane Scale
The crane scale has a built-in rechargeable battery. Before first use, fully charge the scale using the provided power adapter.
- Connect the power adapter to the charging port on the scale.
- Plug the adapter into a suitable power outlet.
- Allow the scale to charge until the charging indicator shows a full charge (refer to the scale's display for battery status).
4.3. Mounting the Scale
Attach the upper hook of the crane scale to a secure lifting mechanism (e.g., crane, hoist). Ensure the connection is stable and capable of supporting the maximum load capacity.

5. Operating Instructions
5.1. Power On/Off
- To power on: Press the ON/OFF button on the scale or the remote control.
- To power off: Press and hold the ON/OFF button on the scale or the remote control until the display turns off.
5.2. Basic Weighing
- Ensure the scale is powered on and displays "0.0" before attaching any load.
- Carefully attach the item to be weighed to the lower hook of the scale.
- Allow the load to stabilize. The weight will be displayed on the LED screen.
Figure 4: Bright LED Display. This close-up image highlights the clear, 5-digit LED display of the crane scale, showing a weight reading and unit indicators (kg/lb).
5.3. Remote Control Functions
The remote control allows for convenient operation from up to 5 meters away. Refer to the diagram below for button functions.
Figure 5: Remote Control Layout. This image illustrates the remote control for the crane scale, with labels pointing to various buttons and their corresponding functions such as Zero, Tare, Hold, and Unit Switch.
- ON/OFF: Powers the scale on or off.
- ZERO: Sets the current display to zero. Use this before weighing to ensure accuracy or to zero out small initial weights.
- TARE: Subtracts the weight of a container or previous load, allowing you to weigh additional items accurately. Press once to tare, press again to clear tare.
- HOLD: Freezes the displayed weight reading, even if the load fluctuates or is removed. Press again to release.
- UNIT (kg/lb): Switches between kilograms (kg) and pounds (lb) measurement units.
- ACC (Accumulation): Used for summing multiple weight readings.
- DEL (Delete): Used to clear accumulated data.
- F1/F2 (Function Keys): May have additional functions depending on the scale's mode or calibration settings. Refer to advanced settings if applicable.
5.4. Overload Alert
If the load exceeds the maximum capacity, the display will show an "OVERLOAD" warning. Immediately remove the excess weight to prevent damage to the scale.
5.5. Auto-Off Function
The scale is equipped with an auto-off feature to conserve battery power. If no operation is performed for a set period, the scale will automatically power off. This setting can typically be adjusted in advanced settings (not covered in basic operation).
6. Maintenance
6.1. Cleaning
Wipe the scale with a soft, damp cloth. Do not use abrasive cleaners or immerse the scale in water.
6.2. Battery Care
- Recharge the scale's internal battery when the low battery indicator appears.
- Replace remote control batteries when they are depleted.
- If the scale or remote will not be used for an extended period, remove the batteries to prevent leakage.
6.3. Storage
Store the scale in a dry, cool place, away from direct sunlight and extreme temperatures. Ensure the hooks are protected from damage.

6.4. Hook Inspection
Regularly inspect the main hook and the lower hook for any signs of wear, cracks, or deformation. Ensure the security latch on the lower hook operates correctly to prevent accidental load release.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Scale does not power on. | Low battery; Power button not pressed correctly. | Charge the scale's internal battery. Press and hold the ON/OFF button firmly. |
| Inaccurate readings. | Scale not zeroed; Unstable load; Overload. | Press ZERO before weighing. Ensure load is stable. Check for OVERLOAD warning and reduce weight. |
| Remote control not working. | Dead batteries; Out of range; Obstruction. | Replace remote batteries. Ensure remote is within 5 meters of the scale. Remove any obstructions between remote and scale. |
| "OVERLOAD" displayed. | Load exceeds maximum capacity. | Immediately remove excess weight. Do not exceed 6600 lbs (3000 kg). |
