We stock a comprehensive range of spares for these machines, ensuring long-term serviceability (Wheels, Throttles, Batteries, etc).

Proper charging is critical for battery health. Note: These are Lead Acid batteries and should be topped up after every use.

If storing the machine for longer than 30 days without use:

• Ensure the batteries are 100% charged before storage.
• Give the barrow a "top-up" charge at least once every 6 weeks.
• Failure to maintain charge can lead to "sulphation," which will permanently reduce battery capacity.

For safe operation and to prevent the machine from tipping, please adhere to these maximum limits:

• Driving Up/Down (Vertical): 30% Incline (Approx. 17°). Always drive straight up or down; never at an angle.
• Driving Across (Horizontal): 15% Incline (Approx. 8°). Exercise extreme caution; the higher the load, the higher the center of gravity.

Pro Tip: When descending a slope with a heavy load, always use Reverse to keep the load's weight over the drive wheels for maximum braking traction.

Maintaining correct brake tension is essential for safe operation, especially when working on inclines.

Correct tyre pressure reduces rolling resistance and prevents premature battery drain.

• Front Drive Wheels: 25-30 PSI
• Rear Steer Wheels: 25-30 PSI

Check pressures monthly, especially before moving heavy 500kg loads.

The overall width depends on the measurement point:

• Front Wheels: The widest point on the outer diameter is approx. 735mm.
• Rear Axle Bolt: The rear axle bolt extends slightly beyond the wheels. Including this bolt, the total max width is approx. 750mm.
