OPERATION & ADJUSTMENTS
WARNING! For your own safety, turn the switch OFF and remove the plug from
the power source before making any adjustements. To avoid injury from thrown
parts due to the spring release, follow instructions carefully and wear safety
glasses.
INSTALLING DRILL BITS
Insert the drill bit (A) Fig.18 into the chuck (B) far enough to obtain the maximum
gripping of the chuck jaws. 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 chuck key (C). Tighten the drill bit well, so that it doesn’t slip while drilling. Turn
the chuck key clockwise to tighten, counterclockwise to loosen.
DRILLING T A SPECIFIC DEPTH
To drill a blind hole (not all the way through) to a given depth, proceed as follows.
1. Mark the depth of the hole on the workpiece.
2. Loosen the depth scale lock knob (A) Fig.19.
3. With the switch OFF, bring the drill bit down until the tip of the lips of the drill bit
are even with the mark (B).
4. Turn the depth scale (C) counterclockwise until it stops moving.
5. Tighten the depth scale lock knob.
6. The drill bit will stop at this depth until the depth scale is readjusted.
AN THER WAY- DEPTH SCALE
1. With the power OFF, loosen the depth scale lock knob (A) Fig.19.
2. Place workpiece on table. Adjust table until the tip of the drill is just a little above
the top of the workpiece.
3. Turn the depth scale (C) clockwise until the depth scale indicator (D) points to
the desired drilling depth on the scale.
4. Tighten the depth scale lock knob.
5. The chuck or drill will now be stopped after traveling downward the distance
selected on the depth scale.
ADJUSTING THE qUILL RETURN SPRING
NOTE: The return spring tension is set at the factory and should not require further
adjustment.
1. With the chuck at its highest possible position, turn the depth scale (C) Fig.19
clockwise until it stops and tighten the depth scale lock knob (A) Fig.19. This
will prevent the quill from dropping while tensioning the spring.
2. Lower the table for additional clearance.
3. Work from the left side of the drill press.
4. Place screwdriver in the lower front notch (A) Fig.20 of the spring cap (B), and
hold it in place while loosening and removing the outer nut (C) (only).
5. With screwdriver remaining in the notch, loosen inner nut (D) (approx. 1/8”)
until the notch disengages from the boss on the head. Do not remove this nut.
6. Carefully turn screwdriver counterclockwise and engage the next notch (E) in
the boss. Do not remove screwdriver.
7. Tighten nut with wrench only enough to engage boss. Do not over tighten as
this will restrict quill movement.
8. Check tension while turning feed handles.
9. If there is not enough tension on the spring, repeat steps 4-8 moving only one
notch each time and checking tension after each repetition.

ADJUSTING THE TABLE SqUARE T THE HEAD
1. Insert a precision round steel rod (A) Fig.21 approximately 3” long into the chuck
and tighten.
2. With the table (B) raised to working height and locked into position, place a
combination square (C) flat on the table beside the rod.
3. If an adjustment is necessary, loosen the table bevel lock bolt (D) with an ad-
justable wrench and loosen the set screw (E) below the table bevel lock bolt.
These adjustments are located under the table.
4. Align the table square to the rod by tilting the table.
5. Retighten the table bevel lock bolt. Retighten set screw.
TILTING THE TABLE
To use the table in a bevel position, loosen the bevel lock bolt (D) Fig.21 with an
adjustable wrench. Tilt the table to the desired angle by reading the bevel scale
on the table support. Retighten the bevel lock bolt.
FEEDING
Pull down the feed handles (A) Fig.22 with only enough effort to allow the drill to
cut. Feeding too slowly might cause the drill to burn...feeding too rapidly might
stop the motor...cause the belt or drill to slip... tear the workpiece loose or break
the drill bit.
H LE L CATI N
Make an indentation in the workpiece where you want the to drill a hole using a
centre punch or a sharp nail. Before turning the switch ON, bring the drill bit down
to the workpiece, lining it up with the hole location.
P SITI NING THE TABLE AND W RKPIECE
Lock the table to the column in a position so that the tip of the drill is just a little
above the top of the workpiece. Always place a piece of back-up material (wood,
plywood) on the table underneath the workpiece. This will prevent splintering or
making a heavy burr on the underside of the workpiece as the drill breaks through.
To keep the back-up material from spinning out of control, it must come in contact
with the left side of the column, as illustrated in Fig.22.
WARNING! To prevent the workpiece or the back-up material from being torn from
your hand while drilling, position them against the left side of the column. If the
workpiece or the back-up material are not not long enough to reach the column,
clamp them to the table. Failure to do this could result in personal injury.
LIGHT & DUAL LASER GUIDE SYSTEM
WARNING! Do not look directly at the laser beams. Do not aim the laser
beams at any person or any object other than your workpiece.
If you desire using the dual laser guides, use the laser switch (A) Fig.23 to
turn them On or Off. If an adjustment to the laser guides are necessary, pro-
ceed as follows;
1) Loosen set screw (B) (one set screw for each laser) and then slightly turn
laser guide (C) in either direction, this will reposition the laser beams tra-
jectory, adjust the position of the laser guides this way until both beams in-
tersect at the point where the drill bit touches the workpiece. Retighten set
screw after each adjustment.
The light On-Off Switch (D) turns On and Off a halogen light bulb which is found
inside the head casting.

MAINTENANCE / TROUBLESHOOTING
LUBRICATI N
All of the ball bearings are packed with grease at the factory. They require no further lubrication. Periodically lubricate the splines (Grooves)
in the spindle and the rack (Teeth of the quill).
WARNING! For your own safety, tur n the switch “OFF” and remove the plug from the power source before maintaining or lubricating your
drill press.
Frequently blow out any dust that may accumulate inside the motor. After operation, remove chips or dirt on the machine and apply a coat
of furniture-type paste wax to the table and the column, this will help keep the surfaces clean and free of rust.
