• Charging: The removable 24V 36AH lithium battery can be charged separately. Connect the charger to the battery and a standard power outlet. A full charge typically takes about 4 hours.
• Endurance: A fully charged battery provides enough power to climb approximately 2400 steps (80-120 floors).
• Battery Indicator: Monitor the LED battery indicator on the control panel to check the remaining power. Charge the battery when the indicator shows low power.
• Storage: If storing the dolly for an extended period, ensure the battery is partially charged (around 50%) and stored in a cool, dry place. Recharge every 3-6 months to prevent deep discharge.
• Safety: Do not use damaged batteries or chargers. Avoid short-circuiting the battery terminals.

Regular maintenance ensures the longevity and safe operation of your hand truck.

• Cleaning: Wipe down the frame and components with a damp cloth. Do not use harsh chemicals or immerse electrical parts in water.
• Track Inspection: Regularly check the rubber tracks for wear, tears, or debris. Clean any debris from the tracks and drive mechanism.
• Wheel Inspection: Inspect the wheels for damage and ensure they rotate freely. Check the locking mechanism for proper function.
• Fastener Check: Periodically check all nuts, bolts, and screws for tightness. Tighten as necessary.
• Lubrication: Apply a small amount of general-purpose lubricant to moving parts, such as axle points, if they become stiff.
