Troubleshooting After Mixing
CONTENTS
1. FEATURES
• Heavy-duty, stainless steel spiral agitator and bowl, designed to Baking Industry Sanitation Standards.
• Instant termination of operation if safety guard is lifted. Operation is possible only when safety guard is in
place.
• Minimal-Maintenance, high-power motor. Speed is altered without shifting gear.
• High-efficiency, 2-speed mixing achieves through blending ingredients to achieve desired results consistently
within 7-10 minutes.
• Accurate timers automatically control mixing time. Machine is still operational even if timer is interrupted.
• New, dual-direction mixing technology, speed is synchronized with reverse-rotating bowl to mix ingredients
and blend dough hydraulically downward. This keeps dough cooler, and achieves desired results more
efficiently.
• Powerful spiral mixing increase water absorption by dough, thus increasing volume and assuring uniform
texture.
• Instant-response servo-limit switch for safety.
• Bowl may be set to rotate either forward or backward.
2. SAFETY PRECAUTIONS
WHEN USING THIS MACHINE, ALWAYS MAKE SURE THE FOLLOWING CONDITIONS OR
OPERATIONS ARE IN EFFECT. FAILURE TO DO SO MAY CAUSE ACCIDENTS.
• KEEP HAND, CLOTHING & RIGID OBJECTS AWAY FROM BOWL AND HUB
ATTACHMENTS WHEN IN OPERATION.
• DO NOT USE THIS MACHINE FOR ANY APPLICATIONS OTHER THAN FOOD PROCESSING.
• USE THE MACHINE ONLY WITH THE ELECTRICAL SERVICE SPECIFIED ON ITS
NAMEPLATE.
• DISCONNECT THE MACHINE FROM ITS POWER SOURCE BEFORE CARRYING OUT ANY
MAINTENANCE.
• DO NOT DISABLE OR REMOVE THE SAFETY MECHANISMS INCLUDED WITH THE
MACHINE.
• DO NOT LEAVE THE MACHINE IN OPERATION UNATTENDED.
• OBSERVE MAINTENANCE AND SAFETY INSPECTION SCHEDULES.

Pulley drive to special fiber belt
2 standard 60 MIN. Timer. (BMSM30 &BMSM40 ARE OPTIONAL.)
Stainless steel safety guard is standard. Instant termination of operation to protect operator if
safety guard is lifted
MOTOR ______________ Three phase motor. Bowl and spiral agitator are driven by separate motors

5. INSTALLATION
Your BAKEMAX® SPIRAL MIXER is shipped fully assembled, and ready for installation. The machine must be
installed on a horizontally-level floor. It should be placed in a location that is convenient for both operation and
maintenance. The machine's safety features make it possible to stand close to the machine during operation.
6. CLEANING
WARNING - UNPLUG MACHINE BEFORE CLEANING OR SERVICING.
• After each day's use, wash the mixer bowl and agitator thoroughly with hot water and a mild soap solution and rinse
with either a mild soda or vinegar solution, rinse thoroughly with a clean damp cloth.
• Clean under machine occasionally. Disconnect power cord, raise stabilizing feet and move machine.

7. ELECTRICAL CONNECTIONS
WARNING: BEFORE CONNECTING YOUR MACHINE TO ANY SOURCE OF ELECTRICAL POWER, READ
THE SPECIFICATIONS ON THE MACHINES NAME PLATE CAREFULLY AND BE SURE THEY COINCIDE
WITH THOSE OF YOUR POWER
SOURCE.
• Electrical connections should be made by qualified personnel in accordance with applicable codes and regulations.
• Appropriate fuse must be installed to provide adequate protection in case of a short circuit.
• Special attention should be given to making the correct electrical connection regarding the direction of rotation of
the spiral agitator. The direction of rotation is indicated by an arrow on the front of mixer.

9. TECHNICAL NOTES
DRIVEN BELT
• The drive belt should be installed with sufficient tension to avoid excessive slack.
• Agitator drive belts may be adjusted by means of a screw No. 1 on motor support plate.
• Bowl drive belts may be adjusted by adjusting the screw nut No. 7 & 8.
• Drive belts for the bowl drive motor may be adjusted by means of the screw No. 2 on lower motor support plate.
