Model 141/161 Receding Geared Threaders
• Follow instructions on proper use of this machine.
Do not use for other purposes such as drilling
holes or turning winches. Other uses or modifying
this power drive for other applications may increase the
risk of serious injury.
• Read and understand the instructions and warn-
ings for all equipment being used including Thread -
ing Machines and Power Drives before operating
the Geared Threaders. Failure to follow all warnings
and instructions may result in property damage and/or
serious injury.
• Do not use this machine if the foot switch is bro-
ken or missing. Foot switch is a safety device that
provides better control by letting you shut off the motor
in various emergency situations by removing your
foot from the switch. For example: if clothing should
become caught in the machine, the high torque will
continue pulling you into the machine. The clothing
itself can bind around your arm or other body parts with
enough force to crush or break bones.

cations for NPT and BSPT versions.
