POWER VISE OPERATING GUIDELINES
• Inspect vise jaws and grips and replace worn or damaged components before drilling.

between the jaws. Check alignment to prevent jaw or rod damage.
• Do not rotate a clamped rod.
• Do not thrust a rod through a closed vise.
• Keep rod centered between guide rollers. Do not continue the bore unless rod is centered
between rollers.
