KM Manual
Standard KM Manual units operate by utilizing torque values applied
with a torque wrench. Use of the proper torque wrench value is critical.
Tighter is not better; component damage can occur.
The specific operating torque of the KM manual clamping units is listed
on each specific unit (torque value information is listed below.
The KM connection must be kept clean and free from nicks and burrs.
KM plugs are available to ensure cleanliness when a cutting unit is not
engaged in the clamping unit.
When a KM head is unlocked, the head will “bump-off”. KM’s 10:1 taper
is a self-locking taper. Because of the self-locking feature, KM requires a
mechanical release. This is accomplished within the design of the KM
System and does not require operator intervention.
After the head has been released, you will need to turn the torque screw
another 3/4 to 1 1/2 turns. This action will feel free of resistance. When
the free turning motion stops, the head is now able to be pulled from the
clamping unit. Do not turn the lock screw further; damage can occur to
the lockrod and/or bump-off pin

Technical Information
KM Tooling Maintenance and Care Instructions
Operator Maintenance:
All tooling showing damage must be replaced. Burrs and nicks should
be removed by “stoning” and/or polishing.
Use plugs to protect clamping units when they are not in use.
Use spindle wipers to clean the clamping units.
For protective plugs refer to page 761.
For spindle wipers refer to page 762.
The KM-LOC II
The KM-LOC II unit is designed for a life expectancy of 50,000 cycles
under normal use.
The KM-LOC II units are greased at the factory during assembly. To
keep the unit operating properly, it should be greased periodically.
Under normal operating conditions, the units should be greased
every 6 months.
How to grease the KM-LOC II:
Remove the standard M4 socket set screw from the bottom of the cam
hex. Thread the grease assembly into the tapped hole. An assembled
grease fitting and adapter are included in the spare parts package. The
spare parts package is included with each clamping unit.
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.
Kennametal recommends and uses GLEITMO 805. This is a white heavy
duty grease paste.
Order #1567575 for one grease cartridge.
Order #1567577 for a 1,000 gram tin.
