Hilti FX 3-A Operating Instructions Manual page 14

▶ Use the product and accessories only when they are in perfect working order.
▶ Never tamper with or modify the product or accessories in any way.
▶ Check that moving parts operate satisfactorily and do not jam, and make sure that no parts are broken
or damaged in such a way that the product might no longer function correctly.
▶ Before you switch the product on, make sure that no-one is going to be put at risk.
▶ To allow sufficient cooling air to enter and exit, when setting up the equipment make sure that it has
50 cm (20 in) of clear space all round.
▶ Never use the welding machine on pressurized gas containers.
▶ An inert-gas can that is not correctly connected or that is damaged is a potential hazard. Check the
connection of the inert-gas can before use and dispose of damaged inert-gas cans in accordance with
your local regulations.
▶ Do not charge or continue to use a damaged welding machine (for example cracks, broken parts,
contacts bent, pushed in or pulled out).
▶ Do not use damaged accessories or studs.
▶ Switch the product off before changing accessories or setting the product aside.
Electric and Magnetic Fields (EMF)
Electric current flowing through any conductor causes localized Electric and Magnetic Fields (EMF). Welding
current creates EMF fields around welding cables and welding machines. EMF may interfere with pacemakers,
hearing aids and other sensitive medical devices. Users and persons working in the near vicinity of the
welding machine, cables and user should consult their physician before working with or in the near vicinity of
this welding machine. Exposure to EMF in welding may have other health effects which are now not known.
The user and all persons in the near vicinity should do the following to minimize exposure to EMF fields
during welding:
• Bundle the lines of the hand tool and the ground cable and secure all lines with adhesive tape.
• Do not place your body between the electrode and the ground cable. If the electrode is on your right
side, the ground cable should also be on your right side.
• Never sling, wrap, or coil the lines around your torso or any body part.
• Keep lines away from head and torso.
• Connect the ground cable to the workpiece as described in these instructions.
• Do not work in the immediate vicinity of the welding machine.
EMF emissions may interfere with surrounding sensitive equipment, including but not limited to:
• Network, signal and data-transmission lines
• Data-processing and telecommunications equipment
• Measurement and calibration equipment
It is the operator's and user's obligation to implement appropriate measures to check, assess, and if
necessary, rectify interferences with equipment in the vicinity of the welding machine and application point(s)
in accordance with international, national, local, or jobsite regulations.
Service
▶ Have your product repaired only by Hilti Service and only with genuine Hilti spare parts. The safety of
the product can thus be maintained.
▶ Stud welding might require additional quality measures according to international and local regulation.
Hilti will provide guidance on Welding Procedure Specification, Welding Procedure Qualification Record
and on Factory Process Control in accordance with international regulation. If you require further support,
consult Hilti Service.
2.2 Careful handling and use of cordless welding machines
▶ Comply with the following safety instructions for the safe handling and use of products with Li-ion
batteries. Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or
explosion.
▶ Use only the Hilti C 53 charger to charge the welding machine. There is a risk of fire if any other charger
is used.
▶ Follow the charging instructions in these operating instructions and in the operating instructions of the
charger. Do not charge the product outside the stated temperature range. Incorrect charging or charging
at temperatures outside the defined range can damage the battery or increase the risk of fire.
▶ Make sure that the product is switched off when it is not in use. Keep the product well away from other
metallic objects such as paper-clips, coins, keys, nails and other small metallic objects that could create
a conductive bridge from one connection to the other. Short-circuiting connections can cause burns or
fires.
