All tools are operated with compressed air at an optimum pressure of 5.5 bar. We recommend the use of pressure regulators and
automatic oiling/filtering systems on the main air supply. These should be fitted within 3 metres of the tool (see diagram below) to ensure
maximum tool life and minimum tool maintenance.
Air supply hoses should have a minimum working effective pressure rating of 150% of the maximum pressure produced in the system
or 10 bar, whichever is the highest. Air hoses should be oil resistant, have an abrasion resistant exterior and should be armoured where
operating conditions may result in hoses being damaged. All air hoses MUST have a minimum bore diameter of 6.4 mm or 1/4inch.
Read servicing daily details page 10.
S T R O K E A D J U S T M E N T
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 stroke adjustment locknut
12, (parts list page 15), is screwed in or out. To shorten stroke,
screw in; to lengthen stroke, unscrew the rear casing. Adjust until
optimum deformation is obtained.
