7.To turn the machine on/off, and adjust the rotational direction of the Chuck (part #132); turn the Switch (part #125) from its “OFF” position to its “FORWARD” position to turn on the machine and for a clockwise rotation of the Chuck. Turn the Switch from its “OFF” position to its “REVERSE” position to turn on the ma- chine and for a counterclockwise rotation of the Chuck. To turn off the machine, turn the Switch to its “OFF” position.

(See Figure B, and Assy. Diagram.)

8.To adjust the speed at which the Chuck (part #132) rotates; First set the High/Low Knob (part #124) until the letter “L” appears on its dial so that the Mirco Mill/Drill Machine begins running at its low speed range (100-1,000 RPM). Turn the Machine on. Note: Adjusting the High/Low Know (part #124) until the letter “H” appears on its dial, will run the machine at its high speed range (100-2,000 RPM). Once the HIGH or LOW speed range has been set, use the Variable Speed Knob (part #122) to fine-adjust the RPM at which the Chuck rotates. NOTE: It is recommended to use a higher speed for softer materials or small holes. Use a lower speed for harder materials and larger holes. (See Figure B, and Assy. Diagram.)
