Product manual (PDF)Charging and battery safety
- Use only compatible charging equipment as described in the product manual. Powerpacks and WFS X2 use USB charging; compatible Powerpacks can also be charged on their matching TPS charger bay.
- Keep batteries dry and away from excessive heat. Do not short-circuit, crush, puncture or open a battery cell.
- Stop using or charging the product if its battery is swollen, damaged, leaking or unusually hot. Contact InkMachines for assistance.
- Do not immerse or rinse the products. Follow the cleaning instructions in the product manual and prevent liquid entering the housing or connectors.
Battery replacement and service
Use a Powerpack intended for the corresponding machine. Do not dismantle the Powerpack or replace its internal cells without model-specific instructions. Contact InkMachines for service and compatible replacement options.
WFS X2 contains a plug-connected battery. Replacement requires the correct cell, protection circuit, connector, polarity and dimensions. Contact InkMachines before ordering or fitting a replacement; a similar battery model number or connector name is not sufficient.
Recycling
Do not dispose of batteries or electronic equipment in household waste. Take them to an approved collection point. Protect exposed battery terminals against short circuits. Do not open, crush or discharge cells for disposal. Ask the collection operator for instructions for damaged batteries.
