  • Replace loose connectors and damaged leads before use. All leads and lines must be securely connected, undamaged and insulated.
  • Do not wrap leads and lines round your body or parts of the body.
  • Disconnect products not in use from the AC supply.
• Disconnect the AC supply and the connection between welding machine and charger before beginning cleaning and maintenance work or if charging is interrupted.
• Do not expose the product to rain or snow. Avoid ingress of moisture.
• To reduce the risk of damage to connectors and leads, when disconnecting always pull only the connector, never the lead.
• Do not operate the charger with a damaged lead or connector. Immediately replace the damaged lead or connector.
• Do not operate the charger if it has received a hard knock, was dropped or has been damaged in any other way.
• Do not disassemble the charger. Incorrect re-assembly can lead to a fire risk and electric shock. If maintenance or repair becomes necessary, consult Hilti Service.
• Operate products with a protective earth conductor only when connected to a power supply system with protective earth and a power outlet with protective earth contact.

Battery charger use and care

• To avoid injuries, use the charger only to charge the battery of the Hilti FX 3-A welding machine.
• To avoid injuries, operate the product only with all safety devices in full working order. Before you switch the product on, make sure that no-one is going to be put at risk.
• 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.
• The use of accessories not recommended or sold by Hilti can lead to a fire hazard, an electric shock or injury to persons.
• The location at which the charger is used should be clean, cool, dry and protected from frost.
• The charger must be able to give off heat while charging is in progress. Accordingly, remove the charger from the toolbox. Do not operate the charger inside a closed container.
• Maintain the product carefully. Check to ensure that no parts are broken or damaged in such a way that the appliance may no longer function correctly. If parts are damaged, have the parts repaired before using the appliance.
• Misuse can result in liquid escaping from the battery. Avoid contact with this liquid. If contact accidentally occurs, rinse with water. Seek medical attention if the liquid comes into contact with the eyes. Liquid escaping from the battery can cause skin irritation or burns.
• Do not charge or continue to use a damaged welding machine (e.g. with cracks, broken parts, bent or pushed-in and/or pulled-out contacts).

Service

• Have your product repaired only by qualified, skilled personnel, using only genuine Hilti spare parts. The safety of the product can thus be maintained.

Preparations at the workplace

CAUTION Risk of injury! Inadvertent starting of the product.

• Unplug the supply cord before making adjustments to the power tool or before changing accessories.

Setting up the product
Set-up conditions for charging and in operation:

• The charger must be able to emit heat while in operation. The air vents must therefore remain unobstructed.
• The surface on which the product is set must be smooth and level, so that the product does not tip over or fall.
• The charger has no protection against the ingress of moisture and is to be used inside dry rooms only.

Charging the battery
Fully charge the battery before using it for the first time:

1. Make sure that the contacts on the welding machine and the contacts on the charger are clean and dry.
2. Connect the charging cord to the charger and to the welding machine.
3. Plug the supply cord plug into a power outlet.
   • The power-in indicator and the charge indicator on the charger show steadily.
   • The battery charge state indicator on the welding machine flashes and the segments show the battery’s current state of charge.
4. If you want to charge the battery more quickly, press the quick charge button.
   • The power-in indicator and the quick charge indicator on the charger show steadily.
   • The battery charge state indicator on the welding machine flashes and the segments show the battery’s current state of charge.
5. When the battery is fully charged the charger automatically switches to the maintenance mode.
   • On the charger, the power-in indicator and the fully-charged indicator show steadily. On the welding machine, all segments of the battery charge state indicator show.
6. Then disconnect the supply cord plug from the power outlet and disconnect the connection between charger and welding machine.
