ASSEMBLY INSTRUCTIONS
3. Choose the desired speed for your drilling
operation, and move the belts (D) to the
indicated position on the pulleys (E). Refer to the
chart on the inside of the belt guard.
4. Loosen the belt tension lock knobs and turn
the belt tension handle (C) counterclockwise to
apply tension to the belts.
5. Tighten the belt tension lock knobs.
NOTE:
The belt should deflect approximately
1/2” by applying finger pressure at the mid-point
of the belt between the pulleys.
6. Close the belt guard.
7. If the belt slips while drilling, readjust the belt
tension.
Installing drill bits
Insert the drill bit into the chuck far enough to
obtain the maximum gripping of the chuck jaws.
The chuck jaws are approximately 1” long. When
using a small drill bit, do not insert it so far that
the jaws touch the flutes (spiral grooves) of the
bit.
Make sure the drill bit is centered in the chuck
before tightening the chuck with the key. Tighten
the drill bit well, so that it doesn’t slip while
drilling. Turn the chuck key clockwise to tighten,
counter clockwise to loosen.
