2.WARNING AND SAEFTY
PRECAUTIONS
Teknomotor S.r.l. does not and cannot know how end users will install
their electrospindles. The installer or customer must therefore perform
risk assessment specific to each installation and application.
It is also the responsibility of the installer to ensure that adequate guards are provided to prevent accidental
contact with moving parts.
The installer and the operator must also bear in mind other types of risk, particularly those associated with
foreign bodies, explosive, inflammable, toxic or high temperature gasses.
Risks associated with maintenance operations must also be guarded against. Maintenance must be performed
in conditions of maximum safety, and only with the electrospindle fully stationary and switched off.
Once the electrospindle has been installed in the way decided upon by the installer and/or customer, the
machine becomes a “finished machine” as defined for the purposes of the Machinery Directive. Overall risk
assessment must therefore be performed on the finished machine and a declaration of conformity produced
in compliance with Appendix IIA of the 98/37/CE Machinery Directive.
2.1. RISKS ASSOCIATED WITH IMPROPER USE AND HANDLING
▪Never impede the functioning of, remove, modify or in any way interfere with any safety device, guard,
or control of individual parts or of the electrospindle as a whole.
▪Never place your hands, arms, or any other part of your body near moving machinery.
▪Never push objects through the cover grill or into the electrospindle either when it is stationary or when
it is operating.
▪Do not use the electrospindle in atmospheres or environments where there is a risk of explosion.
▪Unless you are duly authorized, never attempt to repair faults or electrospindle malfunctions and never
interfere in any way with the electrospindle operation or installation.
▪On completion of servicing work for which guards, covers, or any other protections have been
removed, always make sure that they have been correctly and securely replaced and are fully
functional before re-starting the electro spindle.
▪Keep all protection and safety devices in perfect working order. Also make sure that all warning and
informative plates, labels and symbols are correctly positioned and perfectly legible.
▪When troubleshooting the electrospindle always adopt all the safety precautions listed in this manual
for the purpose of preventing injury or damage to persons and things.
▪After adjusting any mechanical part, make sure that you fully tighten all screws, bolts or ring nuts you
may have slackened or removed.
▪Before you start the electrospindle, make sure that all the safety devices are installed and perfectly
functional. Do not start the electrospindle if this is not the case, but immediately inform the person
responsible for machine safety or your direct superior.
▪Make sure that you have and use all the personal protective equipment (PPE) required by law. Do not
wear loose or hanging clothing (ties, wide sleeves, etc.).
▪Never use types of tool holder that do not correspond to the models those are specify in this manual;
this cause the risk of breakage or imperfect hook-up of the tool holder cone.
ATC41-ISO20 INSTRUCTION MANUAL
DOC.U.A.001.DOCX Rev.02 del 11/11/2019 17
2.2. RISKS SPECIFIC TO ELECTROSPINDLE MAINTENANCE
▪During all maintenance and cleaning operations, take great care if a tool is fitted. It is advisable to
remove any tool before starting cleaning or maintenance.
▪Disconnect the electrospindle from the main supply before carrying out any maintenance operations.
▪The electrospindle can still turn under the effect of inertia even after it has been switched off. Make
absolutely sure that the electrospindle is not still spinning before starting any maintenance on it.
▪Perform scheduled maintenance as specified in this manual to avoid the risk of mechanical failures
from advanced wear.
NEVER Start any maintenance before making absolutely sure the
electrospindle is stopped spinning.
NEVER Start any maintenance on the electrospindle without first
disconnecting it from the electrical power supply.
NEVER Attempt to clean the electrospindle while it is rotating.
3.GENERAL INFORMATION
3.1. PROPER USE OF ELECTROSPINDLE
Electrospindles designed by TEKNOMOTOR S.R.L. shall operate as part of a machine.
MACHINE DESIGN SHALL CONSIDER THAT FRAME OF THE MACHINE
SHALL WITHSTAND THE WEIGHT OF ELECTROSPINDLE FITTED IN AND
THE STRESSES CAUSED BY TYPE OF MACHINING TO CARRY OUT.
TEKNOMOTOR S.R.L. DESIGNED ELECTROSPINDLE FOR LOW-MEDIUM
POWER MILLING AND DRILLING OF WOOD, FIBERBOARD, PLASTICS AND
ALUMINUM (SEE TO TECHNICAL DATA OF THE SPECIFIC
ELECTROSPINDLE MODEL).
USE THE ELECTROSPINDLE ONLY FOR THE PURPOSE FOR WHICH
TEKNOMOTOR S.R.L. DESIGNED IT.
SAFE OPERATION DEPENDS ON THIS.
ELECTROSPINDLES OPERATE AT S1 DUTY CYCLE UNLESS OTHERWISE
IN TECHNICAL DOCUMENTATION OF THE SPECIFIC MODEL.
CUSTOMER SHALL CARRY OPERATION OF THE ELECTROSPINDLE
ACCORDING TO SERVICE TYPE INDICATED IN TECHNICAL
DOCUMENTATION.
ATC41-ISO20 INSTRUCTION MANUAL
DOC.U.A.001.DOCX Rev.02 del 11/11/2019 18
SERVICE TYPE S1 (standard IEC 60034-1) MEANS OPERATION AT
CONSTANT LOAD WITH A DURATION SUFFICIENT TO ENSURE THAT THE
MOTOR REACHES THERMAL EQUILIBRIUM.
3.2. RANGE OF APPLICATION
The product has been designed to carry out milling and boring operations in the field of wood and its derivates,
plastic, composite material, aluminum and light machining operations on other metals.
The quick replacement of the shaft unit complete with bearings is possible on every models, using the shaft
kit. For further information contact the Teknomotor Technical Office.
All the electrospindles have a mechanical reaction system that almost completely cancels the axial force of
the pistons on the bearing during the tool changing phase. It guarantees the long life of the front precision
bearings.

4.2. IDENTIFYNG THE MOTOR DATA FROM THE NAME PLATE
The part number (P.N. or TYPE) and the serial number (S.N.) are printed on the name plate and they are only
way to identify the electrospindle recognized by the manufacturer. For this reason they must be kept legible
throughout the unit’s working life. The place of the name plate and the disposition of data in the name plate
could be different model by model.

5.TRASPORT, PACKAGING,
UNPACKAGING AND STORAGE
5.1. PACKAGING AND LIFTING
▪Lifting and moving the electrospindle can create situations of risk to persons nearby. Always follow the
instructions provided by this manual, follow all possible safety instruction for the handling of heavy
loads. Always use suitable lifting equipment. The responsibility for the safety of the people involved in
handling, moving and lifting operation is of the customer.
▪Installation and assembly work must be performed only by specialist technicians.
▪Always use great care in lifting and moving electrospindles and their components. Avoid impacts which
can damage the body or the shaft or the bearings of the electrospindle.
It is the responsibility of the customer to ensure that the lifting
equipment used is suitable for the purpose in terms of functioning and
load capacity.
Never lift the electrospindle by its fan cover. This can break, damaging
the electrospindle and possibly causing personal injury.
Never drill parts of electrospindle to attach elements useful to move
electrospindle.
Load characteristics
The load is to be considered too heavy for a single person when:
•It weights for more than 30 kg for men
•It weights for more than 20 kg for women
Do not drill the electrospindle to fit any hoisting tool.
5.2. STORAGE
If the electrospindle is to be stored for any length of time, make sure that it is protected against the elements
and in particular against damp, dust, and other forms of damage by the atmosphere or storage environment.
STORAGE TEMPERATURE: from -5°C to +55°C
NON-CONDENSING RELATIVE HUMIDITY: from 5% to 15%
The storage time of Teknomotor electrospindle is 12 months. After
this time-limit the product must be inspected by an authorized
Teknomotor service. If you need more information please contact
Teknomotor S.r.l..
