7. 

To turn the machine on/off, and adjust the rotational direction of the Chuck

(part #13); turn the Switch (part #15) 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 #14) 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 #14) until the letter 
“H” appears on its dial, will run the machine at its high speed range (100-,000 
RPM).   Once the HIGH or LOW speed range has been set, use the Variable 
Speed Knob (part #1) 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.)

workpiece to the Worktable with clamps (not provided).

(See Figure B, and Assy. Diagram.)

4. 

Insert the shank of the drill bit/cutting tool (not provided) all the way up into the 
Chuck (part #13).  Then, use the Chuck Key to tighten the Chuck onto the drill 
bit/cutting tool.
