Assembly

The mixer requires assembly before use. Ensure all components are present as listed in the unpacking section. Key steps include:

• Install bearing housings and the lower drum assembly onto the main frame.
• Attach the angle adjusting plate and tilt handwheel.
• Install the motor/drive assembly, ensuring the drive spindle aligns with the pulley.
• Fit the upper drum to the lower drum, ensuring alignment arrows match, and secure with screws.

Operation

1. Switch the mixer on using the green (I) button.

3. Add cement and aggregate as required.
4. Always keep the drum rotating while loading and emptying.
5. Use the tilt wheel to tip the drum forward for discharge.

Care and Maintenance

Cleaning: It is essential to hose down the machine thoroughly with clean water after every use to prevent cement residue from hardening. The drum can be scoured by running it with coarse gravel and water.

Storage: Store in a dry place out of reach of children. The axle frame and support stand can be folded for storage. Keep the drum inverted to exclude water or debris.

Maintenance: Bearings are sealed for life and require no maintenance. The drive belt is under constant tension and does not require adjustment.
