GUIDE BLADES
After adjusting the AutoGuide, check guide blade tolerances.
When necessary, shim the guide blade to keep the gap within the
specifications listed in the Blade Gap table below.
Rotate the guide blades when worn to a 1/8” (3 mm) radius.
Replace a guide blade when more than 0.075” (2 mm) of shims
are required to keep the blade gap within tolerance.
Dual guide blades, one on either side of the lower jaw, allow for
a wider tip-to-guide blade gap than is used between the main
cutting blades. Friction and heat buildup cause piercing blades
to expand, reducing clearance, possibly to the point of blade
interference. Therefore, in most applications, it is beneficial to
maintain a wider gap at the guide blades.
Shimming
Slowly close the jaw so the upper piercing blades begin to
bypass the guide blades. Stop the jaw and check the gap
between the guide blades and piercing blades. Cycle the jaws
slowly, stopping at several points along the piercing blades to
check the gap each time.
Shim the guide blades as needed to keep the gap within the
tolerances listed in the Blade Gaps table.
To install shims, loosen blade bolts and slide shims between the
guide blade and adjustment plate. Re-torque bolts and recheck
the gap.
