This document provides essential operating instructions for the Hilti NCT IS 053-A22 cordless electro-hydraulic cutting tool. It is intended for professional, trained personnel. Always read the full documentation before use and ensure the tool is in perfect working order.
Product Overview
The tool features a cutting head, manual piston return switch, casing, servicing/fault indicator (red LED), battery release buttons, battery, slots for a retaining leash, working area illumination (white LED), and a control switch.
Intended Use
The tool is designed for cutting copper (Cu) or aluminum (Al) cables. It must not be used in heavy rain, underwater, or clamped in a fixed position. Use only Hilti B 22 series Li-ion batteries and approved chargers.
Operation
Battery Handling: Charge the battery fully before first use. Insert it until it engages with an audible click. Press the battery release buttons to remove it. The charge state is displayed after pressing one of the release buttons.
Cutting Procedure: Rotate the cutting head up to 350° for difficult access. Ensure the cable is fully inserted into the cutting head. Press and hold the control switch until the tool releases pressure (indicated by an audible pop). After approx. 100 consecutive cuts, allow the tool to cool for 15 minutes.
Maintenance and Care
Always remove the battery before maintenance. Clean air vents with a dry, soft brush. Use a slightly damp cloth for the housing; do not use silicone-based cleaning agents. Check all parts for damage regularly. If the tool malfunctions, contact Hilti Service.
Troubleshooting
If the tool fails to operate, check if the battery is correctly inserted, charged, or within the operating temperature range. If the red LED lights up or flashes, refer to the troubleshooting table in the manual for specific error codes and actions, such as allowing the tool to cool down or contacting Hilti Service.
