Quick guide from the manual
This document provides essential operating instructions for the Hilti NCR 120-22 and NCR 120C-22 cordless electro-hydraulic crimping tools. These tools are designed for crimping copper (Cu) or aluminum (Al) connection materials. Always perform a risk assessment before starting work, especially when working near electrical installations.
Product Overview
The tool features a crimping head, control switch, piston return switch, and a side handle. The NCR 120C-22 model includes a specialized two-layer PVC-coated crimping head for added safety.
Operation
Inserting/Removing the Battery: Ensure the tool is switched off before inserting the battery. Push the battery into the tool until it clicks audibly. To remove, press the battery release button.
Starting Lock: The tool features an optional starting lock. When activated, the control switch must be pressed twice to initiate the crimping process. To toggle this, remove the battery, press and hold the control switch, insert the battery, and release the switch.
Crimping Procedure: Ensure the crimping dies are correctly positioned. Turn the crimping head to the desired position, insert the connection material, and press and hold the control switch until the piston retracts. If the piston does not retract, use the manual return switch.
Safety and Maintenance
Always wear personal protective equipment. Inspect the crimping head coating before every use; if the red inner layer is visible or warning symbols are illegible, do not use the tool. Clean air vents with a dry, soft brush. Do not use silicone-based cleaning agents. Hilti recommends an overhaul by Hilti Service after 15,000 crimping operations.
Troubleshooting
The battery status indicator provides feedback on charge levels and potential faults. If the red LED flashes or lights up continuously, consult the troubleshooting table in the manual or contact Hilti Service.
