4.2 STROKE ADJUSTMENT
This adjustment is necessary to ensure optimum insert deformation.
It is suggested, therefore, that a test plate with the same thickness
and hole size as workpiece be used.
If deformation is insufficient, the insert will rotate inside the
application. If deformation is excessive, thread distortion will occur
and possibly drive screw fracture.
The stroke is adjusted by the amount the rear casing
86
is screwed
in or out. To shorten stroke, screw in; to lengthen stroke, unscrew the
rear casing but never more than 5 turns from the fully “IN” position
unless dismantling the tool. Adjust until optimum deformation is
obtained.
Lock the stroke set finger
88
into the rear casing.
4.3 PRINCIPLE OF OPERATION
• Connect tool to air supply.
• Offer up insert, lip first to drive screw. A light pressure will start the motor and automatically thread the insert up
against nose and stop.
• Insert fastener into application squarely.
• Fully depress trigger. This will both place insert into the application and reverse it off the drive screw.
Item numbers in
bold
refer to the General Assembly drawing and parts list (pages 18-19).
CAUTION - do not attempt to force the installation of an insert as this will cause damage to the tool and/or application.
