1. Drill two 3/8" diameter holes (C) Fig. 12B, correspon-

ding to the mounting holes (A) Fig. 12A, of the drill press base

in a 21" by 28" minimum size plywood board (D) Fig. 12B.

2. Fasten the drill press base to the mounting board

using the carriage bolts, nuts, and washers (E) Fig. 12B, fur-

nished with your drill press. The carriage bolt heads must be

countersunk such that the bolt heads are flush with the bot-

tom surface of the mounting board in order to guarantee

proper stability.

3. When the drill press is mounted to the supporting

board, the board must extend a minimum of 3" beyond

each edge of the drill press base, as shown in Fig. 12C.

4. The plywood base must be secured to the floor or

supporting surface if there is any tendency of the drill press to

vibrate, slide or walk during normal operation.

MOTOR SPECIFICATIONS AND

ELECTRICAL REQUIREMENTS

MOTOR SPECIFICATIONS

Your drill press is designed to use a 1720 RPM motor. It is

wired at the factory for 110-120 Volts, 60 Hz alternating cur-

rent. Never use a motor that runs faster than 1720 RPM.

power connections

A separate grounded electrical circuit should be used for your

drill press. This circuit should not be less than #12 wire and

should be protected with a 20 amp fuse or circuit breaker.

Before connecting the drill press to the power line, make sure

the switch is in the “OFF” position.

If the power cord is worn, cut or damaged in any way, have it

replaced immediately by a certified electrician to avoid elec-

trical shock or fire hazard.

EXTENSION CORDS

Use proper extension cords. Make sure your extension cord

is in good condition. When using an extension cord, be sure

to use one heavy enough to carry the current your product will

draw. An undersized cord will cause a drop in line voltage

resulting in loss of power and overheating.

Fig. 12D, shows the correct gage to use depending on cord

length and nameplate ampere rating. If in doubt, use the next

heavier gage. The smaller the gage number, the heavier the

cord.
