• Control Handle: Used for steering and controlling forward/reverse movement.
• Lifting/Lowering Buttons: Located on the control handle, these buttons control the vertical movement of the forks.
• Emergency Stop Button: A prominent red button that immediately cuts power to the unit in an emergency.
• Movable Joystick: Provides precise control over fork movements.

3.2. Basic Operation

1. Starting the Stacker: Ensure the emergency stop button is disengaged (pulled out). Turn the key switch (if present) to the ON position.
2. Driving: Use the control handle to steer. Gently push or pull the handle to engage forward or reverse motion. The speed is typically controlled by the angle of the handle or a dedicated speed control.
3. Lifting Loads: Position the forks under the pallet. Press and hold the "Lift" button on the control handle until the desired height is reached. Ensure the load is stable and centered on the forks.
4. Lowering Loads: Press and hold the "Lower" button to slowly descend the forks. Ensure the area below is clear.
5. Braking: The electromagnetic service brake engages automatically when the control handle is released or moved to the upright/downright position. The emergency stop button provides immediate braking.

4. Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your pallet stacker.

• Battery Care:
  • Charge the battery fully after each use, or at least once a week if not in frequent use.
  • Avoid deep discharges, which can shorten battery life.
  • Keep battery terminals clean and free of corrosion.
• Lubrication: Periodically lubricate all moving parts, including chains, mast channels, and pivot points, with appropriate grease or oil.
• Wheel Inspection: Regularly check the polyurethane wheels for wear, damage, or debris. Replace worn wheels to ensure smooth operation and prevent floor damage.
• Hydraulic System: Check hydraulic fluid levels and inspect for any leaks. Ensure seal rings and wear strips are intact to prevent oil leakage.
• General Inspection: Routinely inspect all bolts, nuts, and fasteners for tightness. Check electrical connections for security and signs of wear.
