Stroke Adjustment

Adjust the exact stroke to meet the optimum pull force. Make sure the tool will be
adjusted by technician or trained personnel for the first time use.
It is suggested that a test plate with the same thickness, material and hole size as

supplied as standard with fitted M6 insert nut. If M3, M4, M5 insert nut is required,
turn the ring nut towards the "-" mark with the stroke regulation pin to shorten stroke
to optimum. If M8, M10 insert nut is required, turn the ring nut towards the "+" mark
with the stroke regulation pin to lengthen stroke to optimum.
Notice: Re-setting the insert nut is prohibited for the insufficient
Adjust the mandrel protrusion before operating. Take the
mandrel protrudes by one thread from the back of the nut
as standard (see Fig.1). If the mandrel protrudes too long or
too short, adjust the nose piece to the optimum position
and lock the set nut well.
This adjustment is necessary to ensure optimum insert
deformation. If the stroke is too long, the insert nut thread
distortion will occur and possibly the screw mandrel sticks
inside the insert nut, even screw mandrel fracture. While if
the stroke is too short, the deformation is insufficient, the
insert nut will rotate inside the application.
