This tool is intended for use on a circuit that has an
outlet and a plug that looks like the one shown in Fig. 19.
A temporary adapter, which looks like the adapter illus-
trated in Fig. 20, may be used to connect this plug to a
2-pole receptacle, as shown in Fig. 20, if a properly
grounded outlet is not available. The temporary adapter
should be used only until a properly grounded outlet can
be installed by a qualified electrician. THIS ADAPTER IS
NOT APPLICABLE IN CANADA. The green-colored
rigid ear, lug, and the like, extending from the adapter
must be connected to a permanent ground, such as a
properly grounded outlet box, as shown in Fig. 20.

WARNING: IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE HAVE A CERTIFIED ELECTRICIAN CHECK THE RECEPTACLE.
SPINDLE SPEEDS
Five spindle speeds of 620, 1100, 1720, 2340 and 3100
RPM are available with the 10" Bench Drill Press. The
highest speed is obtained when the belt is on the largest
step of the motor pulley and the smallest step of the
spindle pulley, as shown in Fig. 21. Fig. 21, illustrates
which steps the pulleys the belt must be placed to
obtain the five speeds available.

A belt positioning and speed chart (A) Fig. 22, is
conveniently located on the inside top cover of the drill
press for your convenience.
CORRECT DRILLING
SPEEDS
Factors which determine the best speed to use in any
drill press operations are: kind of material being worked,
size of hole, type of drill or other cutter, and quality of cut
desired. The smaller the drill, the greater the required
RPM. In soft materials, the speed should be higher than
for hard metals.
WARNING: Use the recommended speed for the
drill press bit and workpiece material. As a guideline
for the speed to use for different drill diameters and
materials, refer to the chart (A) Fig. 22, located on the
inside top cover of the drill press for your
convenience.
