Note: Cleaning the paddles and drum between batches
prevents material from drying and contaminating the
next batch of material.
Cleaning the Drum
Service Interval: After each use
Important: Do not strike on the drum with a shovel,
hammer, or any other device to loosen any accumulated
dried materials.
1. While the machine is running, use the handwheel to
tilt the drum slightly.
2. Engage the drum-tilt brake to prevent the drum from
tilting further and discharging the water.
3. As the drum is rotating, spray it thoroughly with water
before the material dries.
4. Allow the drum to rotate and tumble the loose material
and water, further loosening the rest of the material.
5. Continue to spray the drum with water to remove all
material from the drum and mixing paddles.
6. When you have removed all material from the surfaces
of the drum and mixing paddles, disengage the
drum-tilt brake and use the handwheel to tilt the drum
and dump the water from the drum.
7. If some material still remains in the drum, spray the
drum with water while it is tilted downward, allowing
the water and material to run out.
