The Hougen-Ogura Electro-hydraulic Hole Puncher
is an integrated unit, containing the electric motor,
hydraulic pump, and "C"-frame punching unit. It uses
hydraulic power to force the punch through the workpiece,
and a strong spring to return the punch piston to its
"home" position. The patented design includes an
automatic valve that releases the hydraulic pressure
when the punch piston is at the bottom of its stroke. The
automatic valve remains open until the punch piston has
fully returned to the home position.
As a result of this design, the piston will not return to its
home position automatically unless the full stroke has
been completed. Also, the punch will not begin another
stroke unless the punch has fully returned to the home
position, resetting the automatic valve. To allow the punch
piston to be manually returned in the event that the punch
cycle is stopped prior to completion, a manual return
valve is provided.
PRINCIPLES OF OPERATION
CAUTION! To prevent electric
shock, do not use power tools
near wet areas, or where power
tool may become wet.
Always wear eye protection while
using punching tools, or in the
vicinity of punching.
CAUTION! The slug is ejected at
the end of the punch. Do not aim
the unit so that ejected slug may
hit someone around, or below
you.
SAFETY FIRST

crushing . Keep away from
