KM Manual

Standard KM Manual units require a torque wrench to activate. Using the proper torque wrench value is critical. Tighter is not better because over tightening can cause damage. The specific operating torque of the KM manual clamping units is listed on each unit (torque value information is listed to the right). 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 self-locking, and therefore, 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 3/4–1-1/2 turns. This rotation will feel free of resistance. When the free turning motion stops, the head can be pulled from the clamping unit. Do not turn the lock screw further, as damage can occur to the lockrod and/or bump-off pin.

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 spindle wipers, refer to page J31.
