NOTE
This connector pin bolt is special. When replacing this
bolt consult the parts section of this manual for the
correct part number.
BEARING BRACKET
Grease the bearing bracket every month.
CLEANING
Always disconnect the spark plug wire before cleaning the inside
of the drum.
Never pour or spray water over the gasoline engine or electric
motor.
For consistent performance, long life and high quality mixing,
thoroughly clean the mixer inside and out at the end of each
day’s operation. To prevent lumps of dried mortar from forming
and contamination of future batches, do not allow a buildup of
materials to form on the blades or anywhere inside the drum.

plug or electrical power cord before attempting
this procedure.
