3 WARNINGS AND SAFETY PRECAUTIONS
HSD does not and cannot know how end users will install their electro-spindles. 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 electro-spindle fully stationary and switched off.
Once the electro-spindle 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.
3.1 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 electro-spindle 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 electro-spindle either when it is stationary or when it is
operating.
• Do not use the electro-spindle in atmospheres or environments where there is a risk of explosion.
• Unless you are duly authorised, never attempt to repair faults or electro-spindle malfunctions and never interfere in
any way with the electro-spindle’s 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 electro-spindle 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 electro-spindle, make sure that all the safety devices are installed and perfectly functional. Do
not start the electro-spindle 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 start electro-spindles fitted with tool engagement keys unless a tool is in place and correctly locked. In
particular make sure that the key engages the tool correctly.
3.2 RISKS SPECIFIC TO ELECTRO-SPINDLE 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.
• The electro-spindle can still turn under the effect of inertia even after it has been switched off. Make absolutely sure
that the electro-spindle 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 THAT THE ELECTRO-SPINDLE IS HAS STOPPED
SPINNING.
START ANY MAINTENANCE ON THE ELECTRO-SPINDLE WITHOUT DISCONNECTING IT FIRST FROM THE ELECTRICAL
POWER SUPPLY.
ATTEMPT TO CLEAN THE ELECTRO-SPINDLE WHILE IT IS ROTATING.
