2. Safety Information

Adherence to safety guidelines is crucial for preventing injury and equipment damage. Always operate the pallet jack responsibly.

• Load Capacity: Never exceed the maximum load capacity of 4,400 lbs (2,000 kg). Overloading can cause structural damage and lead to accidents.

• Personal Protective Equipment (PPE): Always wear appropriate safety footwear and gloves when operating the pallet jack.
• Load Stability: Ensure loads are properly centered and stable on the forks before lifting and moving. Unstable loads can shift and fall.
• Clearance: Maintain clear visibility and be aware of your surroundings, including personnel, obstacles, and overhead clearances.
• Scale Accuracy: The built-in scale is for internal logistics and inventory management. It is not legal for trade and should not be used for commercial transactions requiring certified weight measurements.
• Emergency Stop: Familiarize yourself with the handle's control lever for quick lowering of forks in an emergency.

5. Operating Instructions

5.1 Moving the Pallet Jack

1. Ensure the control lever on the handle is in the NEUTRAL position (middle position) for easy steering.
2. Push or pull the handle to move the pallet jack to the desired location.
3. The polyurethane wheels are designed for smooth movement on flat indoor surfaces.

5.2 Lifting a Load

1. Position the pallet jack so the forks are aligned with the pallet openings.
2. Push the pallet jack forward until the forks are fully inserted under the pallet.
3. Move the control lever to the LIFT position (upward).
4. Pump the handle up and down to raise the forks and lift the pallet off the ground. Lift only high enough to clear the floor for movement.

5.3 Lowering a Load

1. Ensure the area is clear before lowering the load.
2. Move the control lever to the LOWER position (downward).
3. The forks will slowly descend. Release the lever to stop lowering at any point.
4. Once the pallet is fully on the ground, pull the pallet jack away from the pallet.

5.4 Using the Digital Scale

The integrated digital scale allows for simultaneous transport and weighing.

1. Power On/Off: Press the ZERO ON/OFF button to turn the scale on or off.
2. Weighing: Once the pallet is lifted, the weight will be displayed on the dual-color LED screen.
3. Unit Switching (lb/kg): Press the INQUIRE RED/GREEN button (short press) to switch between pounds (lb) and kilograms (kg).
4. Tare Function: To zero out the weight of a container or pallet, place the empty item on the forks, then press the TARE button. The display will show zero, and subsequent items added will show their net weight.
5. Accumulation: The scale can sum multiple weights. Refer to the scale's specific instructions for detailed accumulation procedures.
6. Counting Mode: For counting identical items, the scale can be set to counting mode. Consult the scale's manual for calibration and operation of this feature.
7. Weight Memory: The scale can store weight readings. Refer to the scale's specific instructions for accessing and utilizing weight memory.
