OPERATION
BASIC DRILL PRESS OPERATIONS
NOTE: This machine incorporates view windows on the pulley
cover used to observe the location of the belt.
W A R N I N G
To avoid possible injury, keep guard
closed and in place while tool is in
operation.
SPEEDS AND BELT PLACEMENT (FIG. S)
This drill press has 5 speeds, as listed below:
620 RPM 1100 RPM 1720 RPM
2340 RPM 3100 RPM
See inside of the pulley guard for specific placement of the
belts on the pulleys to change speeds.
ON/OFF SWITCH (FIG. T)
The ON / OFF switch has a removable, safety switch key.
With the key removed from the switch, unauthorized and haz-
ardous use by children and others are minimized as the switch
can not be turned on without the key.
1. To turn the drill press “ON”, insert key (2) into the slot
of the switch (1). Move the switch upward to the “ON”
position.
2. To turn the drill press “OFF”, move the switch downward.
3. To lock the switch in the OFF position, grasp the sides of
the safety switch key, and pull it out.
4. With the switch key removed, the switch will not turn the
power tool on.
5. If the switch key is removed while the drill press is running,
it can be turned “OFF” but cannot be restarted without
inserting the switch key.
W A R N I N G
ALWAYS lock the switch “OFF” when
the drill press is not in use by removing
the safety switch key keep it in a safe place. In the event
of a power failure, blown fuse, or tripped circuit breaker,
turn the switch “OFF” and remove the key, preventing an
accidental startup when power comes on.
INSTALLING DRILL BIT IN CHUCK (FIG. U)
1. With the switch “OFF” and the switch key removed, open
the chuck jaws (1) using the chuck key (2). Turn the chuck
key counterclockwise to open the chuck jaws (1).
2. Insert the drill bit (3) into the chuck far enough to obtain
maximum gripping by the jaws, but not far enough to touch
the spiral grooves (flutes) of the drill bit when the jaws are
tightened.
3. Make sure that the drill is centered in the chuck.
4. Turn the chuck key clockwise to tighten the jaws.
W A R N I N G
To avoid injury or accident by the chuck
key ejecting forcibly from the chuck
when the power is turned “ON”, use only the self-ejecting
chuck key supplied with this drill press. ALWAYS recheck
and remove the chuck key before turning the power “ON”.
USING THE FENCE (FIG. V)
The fence provides a way of accurately and quickly setting up
the workpiece for precision or for repitive drilling operations.
1. Using a centerpunch or sharp nail, make an indentation in
the workpiece where you want to drill.
2. Align the laser lines (x) with the indentation on the
workpiece.
3. Loosen the knobs (1) and slide the fence back stop (2)
firmly against the long side of the workpiece. Tighten the
knobs when in position.
