REV 0.0
SAFETY
2
The potential of danger changes due to the interplay of the hydraulic breaker and the support frame
because the hydraulic breaker is mounted on the support frame. This operating manual does not
replace the operating manual of the support frame on which the hydraulic breaker is mounted.
This operating manual must be read and followed.
The safety instructions help to prevent personal injury or damage to property when dealing with
the hydraulic breaker and the environment. All users must read these safety instructions and follow
them at all times.
In addition to the operating manual, the universally valid as well as local regulations regarding accident
control, safety at work and rules for environment protection must be provided and observed.
Follow the instructions about using the hydraulic breaker in the support frame operating manual.
• Use the hydraulic breaker only if it is in a technically sound condition.
• Repair the defects in the hydraulic breaker immediately. Inform TECNA immediately in case of
malfunctions. Do not make any modifications or re-constructions in the hydraulic breaker,
otherwise the declaration of conformity becomes invalid and the operating permit is terminated.
• Check the hydraulic breaker for visible defects such as cracks in the casing, screws, covering
caps or seals.
• You may not fundamentally modify or re-construct the hydraulic breaker.
• Use the hydraulic breaker within the range of capacity only, which is specied in the Technical Details.
• Do not use the hydraulic breaker in explosive environments if there is no explicit permission for it.
• Close the front panel of the support frame before you start working with the hydraulic breaker.
• Wear the necessary protective equipment, e.g. protective helmet, ear muffs, protective clothing
among other things as per the requirements.
• Do not wear loose clothing or jewellery that could get caught in the operating elements or other
parts of the support frame.
• Persons who are under the influence of alcohol, drugs or medicines may not transport, mount,
commission, operate or repair the hydraulic breaker.
• Only ask for standard signs and that too from one person only when working on the site.
• The minimum age limit for the operating personnel is 18 years.
• Fasten all the loose objects such as tools and remove these objects from catwalks, levels, etc.
• Ensure that all the safety equipment belonging to the hydraulic breaker is available, installed
properly and is fully functional. You may not change the position of the safety equipment,
handle it or make it ineffective.
• Ensure that the activated user can be brought into a safe position (e.g. immediate stop) by using
a proper EMERGENCY STOP function.
• Follow the warning and instruction signs attached to the hydraulic breaker. In addition, ensure
that these signs are not removed and that they are always legible.

2.4.1 GENERAL INSTRUCTIONS
• Comply with the prescribed purity level as per ISO 4406 (c) of the hydraulic pressure medium
• You can find information regarding the purity level in the support frame operating manual.
• Take measures to ensure that there are no dangerous situations for persons and property
parameters if the need arises to stop the safety equipment for commissioning or maintenance
work for instance. Follow the above-mentioned support frame operating manual for this.
RISK OF BURNS!
The hydraulic breaker heats up intensely during operation and can get very hot when in operation
and may cause burns.
»Allow the hydraulic breaker to cool down before you touch it.
»Protect yourself with heat-resistant protective clothing e.g. gloves.
»Follow the ISO 13732-1 and EN 982 standards as well.
• The guarantee is applicable solely for the delivered design.
• The guarantee expires in case of incorrect mounting.
• Pay attention to high-voltage lines, underground cables and feed lines so that they are not
damaged during operation. If they are damaged, measures must be taken immediately such that
there is no danger due to it.
• Do not work with the hydraulic breaker if any persons are present on the hydraulic breaker.
• Depending on the type of connection, keep in mind the pressure condition when connecting to
the hydraulic system and when separating from the hydraulic system. The hydraulic system must
be operated at zero pressure in case of an emergency.
• Keep persons and animals away from the sphere of activity of the hydraulic breaker during all the
mounting and maintenance work.
• Never leave the hydraulic breaker unsupervised during the mounting and maintenance work.
• The hydraulic breaker may not be operated without the safety equipment and protective caps
attached by TECNA or those installed by customers.
• The defective components must only be replaced with the original parts having the same
hydraulic and mechanical data, otherwise the safety and functioning cannot be maintained.
• All the safety equipment, fastenings as well as hydraulic connections and lines must be regularly
checked for flawless condition.
• In case of injuries, visit a doctor who is knowledgeable about these injuries.
• Use sufficient respiratory protection in case of lot of dust formation or dust containing asbestos.

2.4.1 GENERAL INSTRUCTIONS
FOR TRANSPORTATION
• Follow the transportation instructions on the packaging.
FOR MOUNTING AND REMOVING
• Follow the instructions of the manufacturer when using mechanical and hydraulic changing
equipment.
• Follow the support frame-specific instructions and the safety instructions of the support frame
manufacturer when mounting without changing equipment.
• Connect the connections to the support frame at zero pressure before you mount the hydraulic
breaker.
• Only use a proper tool for that.
• Lay the lines such that they are not damaged.
• Ensure before commissioning that all the seals and fasteners at the ends are fit correctly and are
undamaged such that liquids and foreign bodies cannot enter into the hydraulic breaker.
• Pay attention to utmost cleanliness when mounting so as to avoid impurities from entering the
hydraulic lines, which could lead to wear and malfunctions in the hydraulic breaker and support frame.
FOR COMMISSIONING
• Ensure that all the hydraulic connections are covered or closed. Operate a fully installed hydraulic
breaker only.
FOR CLEANING
• Close all the openings using suitable protective equipment such that the cleaning agents do not
enter the system.
• Use a suitable cleaning device for cleaning and follow the instructions regarding the cleaning device.
• Wear protective clothing (e.g. protecting goggles, face mask among other things) when dealing
with compressed air or pressurised water.
FOR MAINTENANCE
• Carry out the prescribed maintenance work at intervals specified in the operating manual.
• Ensure that no line links, connections and components come off till the system is under pressure.
• Do not search for leakages with bare hands; the pressure medium can come out with high pressure
which can cause injuries.
FOR DISPOSAL
• Dispose of the hydraulic breaker as per the country-specific regulations.
• Dispose of the pressure medium or grease as per the country-specific regulations.
• Dispose of the pressure medium residues or grease in accordance with the valid safety data
sheets for pressure mediums and grease.
• Consult TECNA or your dealer when using biodegradable mediums.
