of standoff is greater than this, the unit is either error proofed or the tapers are contaminated. Rotate the head 180° for correct, free-state standoff. Next, insert a wrench with the properly sized metric bit into the cam socket. Rotating the cam socket clockwise 145° (where it will stop) locks the head

into the clamping unit. The dimples on both the cam and clamping unit body

activation cam are aligned when a positive stop is reached.

KM-LOC II Unlocking Sequence Remove chips or foreign material from around the cutting unit flange and clamping body. Insert the metric bit into the cam and rotate counterclockwise to unlock the unit. During this procedure, the lockrod will make contact with the inside of the

cutting unit (this could feel like a positive stop), continue the counterclockwise turn until the head moves apart from the gage face. When unlocked, a KM head will bump off. The KM System utilizes a 10:1 self-locking taper that requires a mechanical release.

under normal conditions, done regularly every six months.

Approximate grease amounts are as follows: KM32™ ............0.2–0.3 fl. oz KM40™ ............0.3–0.4 fl. oz. KM50™ ............0.5–0.6 fl .oz. KM63™ ............0.5–0.6 fl. oz.
