Clarke 135L Cement Mixer Operation & Maintenance Instructions

Quick guide from the manual

This document provides essential instructions for the safe assembly, operation, and maintenance of the Clarke 135L Cement Mixer (Model CCM135). Always ensure the machine is placed on firm, level ground and never operate it on a gradient to prevent tipping. Always disconnect the power supply before performing any maintenance or cleaning.

Safety Precautions

• Always wear suitable protective clothing, including industrial gloves, ear defenders, and impact-resistant safety glasses.
• Wear a dust mask when handling cement.
• Keep children and bystanders away from the work area.
• Never put hands or tools inside the drum while it is rotating.
• Never leave the machine running unattended.
• Ensure the electrical cable is protected and inspected for damage before every use.

Assembly

1. Bolt the mixing blades to the drum using the provided screws, leather washers, and nuts.
2. Attach the protective plastic drive guard to the frame.
3. Bolt the drum to the frame using the M12x30 bolt.
4. Attach the drive motor assembly to the frame, ensuring the drive shaft is aligned.
5. Secure the handles to the main frame.
6. Slide the wheels onto the axles and secure them with large washers and cotter pins.

8. Lift the mixer onto the stand (requires two people).

Operation
