WARNING:
If the tool is dropped for any reason the lanyard connection
must be inspected and properly serviced prior to reuse. The
lanyard connection is designed to stretch to absorb the
shock of a drop. Any permanent stretch to the connection
exposing the red marked internal coils indicates it has been
compromised and must be serviced prior to reuse.
• Do not use hang hook as lanyard attachment point.
• Only use batteries that contain the integral battery strap.
Do not use unsecured batteries while the tool is tethered.
Unsecured batteries may detach from the tool if dropped.
• Always keep the tool and accessories tethered when
working "at height." (Maximum lanyard length: 6.5 ft [2 m].)
• Use only with lanyards appropriate for this tool type and
