Safety
We at Taylor Company are committed to manufacturing
safe operating and serviceable machines. The many
built-in safety features that are part of all Taylor machines
are aimed at protecting operators and trained service
technicians alike.
This manual is intended exclusively for Taylor authorized
service personnel.
Per IEC 60335-1 and its part 2 standards, “This
appliance is to be used only by trained personnel. It is not
intended for use by children or people with reduced
physical, sensory, or mental capabilities, or lack of
experience and knowledge, unless given supervision or
instruction concerning the use of the appliance by a
person responsible for their safety.”
NOTICE! This manual is intended exclusively
for authorized Taylor service personnel.
CAUTION! DO NOT attempt to run the machine
unless you have been properly trained to do so. Failure
to do so can result in personal injury or machine damage.
WARNING! This machine must be properly
grounded! DO NOT operate this machine unless it is
properly grounded and all service panels and access
doors are restrained with screws. Failure to do so can
result in severe personal injury from electrical shock!
WARNING! Avoid injury.
•DO NOT attempt any repairs unless the main
power supply to the machine has been
disconnected.
•DO NOT operate the machine with larger fuses
than specified on the data label.
• Stationary machines which are not equipped
with a power cord and plug or other device to
disconnect the machine from the power source
must have an all-pole disconnecting device with
a contact gap of at least 0.125 in. (3 mm)
installed in the external installation.
• Machines that are permanently connected to
fixed wiring and for which leakage currents may
exceed 10 mA, particularly when disconnected,
not used for long periods, or during initial
installation, shall have protective devices to
protect against the leakage of current, such as a
GFI, and be installed by authorized personnel to
the local codes.
• Supply cords used with this machine shall be
oil-resistant, sheathed flexible cable, not lighter
than ordinary polychloroprene or other
equivalent synthetic elastomer-sheathed cord
(code designation 60245 IEC 57) installed with
the proper cord anchorage to relieve conductors
from strain, including twisting, at the terminals
and protect the insulation of the conductors
from abrasion.
•For Cord-Connected Machines: Only
authorized Taylor service technicians may
install a plug on this machine.
Failure to follow these instructions may result in
electrocution or damage to the machine.
IMPORTANT! This machine is provided with
an equipotential grounding lug that is to be properly
attached to the rear of the frame by the authorized
installer. The installation location is marked by the
equipotential bonding symbol (5021 of IEC 60417-1) on
the removable panel and the frame.

CAUTION! DO NOT remove the machine door
or any internal operating parts (examples: beater, scraper
blades, etc.) unless all control switches are in the OFF
position. Failure to follow these instructions may result in
severe personal injury from hazardous moving parts.
WARNING! This machine has many sharp
edges that can cause severe injuries.
Examples:
• Scraper blades
• Condenser fins
• Cup/cone dispenser (if applicable)
CAUTION! This machine must be installed on
a level surface to avoid the hazard of tipping. Extreme
care should be taken in moving this machine for any
reason. Two or more persons are required to safely move
this machine. Failure to comply may result in personal
injury or machine damage.
WARNING! Only install this machine in a
location where its use and maintenance is restricted to
trained personnel. Failure to comply may result in
personal injury.
WARNING! This machine must NOT be
installed in an area where a water jet or hose can be
used. NEVER use a water jet or hose to rinse or clean
the machine. Failure to follow this instruction may result
in electrocution.
NOTICE! Cleaning and sanitizing schedules
are governed by your federal, state, or local regulatory
agencies and must be followed accordingly. Please see
the cleaning section of this manual for the proper proce-
dure to clean this machine.
Important! Authorized service personnel must ensure
that the proper personal protective equipment (PPE) is
available and worn when required during installation and
service.
IMPORTANT! Access to the service area of
the machine is restricted to persons having knowledge
and practical experience with the machine, in particular
as far as safety and hygiene are concerned.
