8.0 Machine Operation

1. Insert drill bit into chuck jaws about 25mm deep. When
using a small bit, do not insert it so far that the jaws touch
the flutes of the bit. Make sure bit is centered in chuck
before tightening chuck with key.
2. For a small workpiece that cannot be clamped to the table,
use a drill press vise. The vise must be clamped or bolted
to the table. Always use a back-up piece of scrap wood to
cover the table. This protects both table and drill bit.
WARNING:
Workpiece must be clamped to table or secured in a vise
that is securely fastened to table. Failure to comply may
cause serious injury.
3. Lower the chuck guard (F, Fig. 6-1)
4. Feed the bit into the material with only enough force to
allow the drill bit to work. Feeding too slowly may cause
burning of the workpiece. Feeding too quickly may cause
the motor to stop and/or the drill bit to break.
The drill press is overload protected. The motor will stop
automatically when you over force the drill press.
When motor overload has reacted, cycle the Main Power switch
(R) to restart the machine again.
Push main power OFF-Switch (V).
Push the main power ON-Switch (R).
