Always cool the motor by running at no load for a few minutes whenever it stops from either overheat or overload. 7) SAFETY CLUTCH This machine is equipped with a mechanical clutch to protect the operator and machine from excessive torque forces. - Page 14 ABOUT DIAMOND BITS The diamond impregnated segments in a wet type (sintered) diamond core bit operate on a principle of controlled erosion. The bond matrix holding the diamonds is continually worn away by abrasion with the work piece, exposing the harder diamonds to stand proud from the bond matrix. A bit with good diamond exposure is a sharp bit.
