HOLE PUNCHING
1. Make a small incision on the surface of the workpiece where you want to make the hole, using a punch or
sharp nail.
2. Install the necessary drill bit and adjust the drill bit to an appropriate speed, then lower the spindle and align
the center of the drill bit with the center punch mark.
3. Connect the machine and pull down with the cranks on the shaft, with enough pressure to allow the drill
to cut.
ATTENTION:
• Drilling too slowly can cause the drill bit to burn.
• Drilling too fast can stop the engine, cause the belt or drill to slip, tear the workpiece or break
the drill bit.
• When drilling metal, it may be necessary to lubricate the tip of the drill bit with a suitable
lubricant to prevent overheating of the drill bit or workpiece.
SPEED AND BELT TENSION ADJUSTMENT
1. Lift the belt cover.
2. Loosen (turn counterclockwise) the belt tensioning screw (12). Unscrew it so that the motor can advance far
enough to loosen the V-belt.
3. Move the V-belt to the corresponding pulleys. The larger the pulley of the drive motor and the smaller the
pulley of the spindle, the faster the speed of the spindle.
4. Push the motor back to apply tension to the belt.
5. Tighten (turn clockwise) the belt tensioning screw. When properly tensioned, the belt should deflect
approximately 1/2" (13mm) when tightened moderately at the midpoint between the pulleys.
6. Close the belt cover.
