MIXER CLEANING
It is important that the drum interior is free of dried material.
Obstructions can cause the paddle blades to lock against
the drum resulting in sudden dump handle movement.
1. Stop the engine. Push the Start/Stop switch on the
engine cover inward to the “ OFF” position.
2. Place the hydraulic paddle lever in "neutral" position
to disengage.
3. ALWAYS disconnect the spark plug wire or disconnect
electrical power source before cleaning the inside of
the drum.
4. Place "Do Not Operate" tag on mixer.
5. Make sure the rear section of safety grate is connected
to the mixing drum.
6. At the end of each day’s operation, place mixer drum in
an upright position and spray inside of tub immediately
with water to prevent lumps of dried mortar or plaster
from forming and contamination of future batches. DO
NOT allow a buildup of materials to form on the blades
or anywhere inside the drum.
7. Rotate mixer to dump position and remove debris.
8. Thoroughly clean the entire mixer, cabinet, and frame.
9. NEVER pour or spray water over the engine or electric
motor (Figure 33).
