DRILL PRESS ADJUSTMENTS
CAUTION
All the adjustments for the operation of the drill press
have been completed at the factory. Due to normal
wear and use, some occasional readjustments may
be necessary.
WARNING
To avoid injury from an accidental start, ALWAYS make
sure the switch is in the OFF position, the switch key
is removed, and the plug is not connected to the pow-
er source outlet before making belt adjustment.
ALIGNING THE BELT PULLEYS (FIG. K)
Open the head cover of the Drill Press. Check alignment of
the pulleys with a straight edge (1) such as a framing square,
a level, or a piece of a wood. Lay the straight edge across the
top of the pulleys. If all three pulleys are NOT aligned:
1. Release belt pressure by loosening the belt tension lock
knobs (2) on either side of the head, counter clockwise.
2. Loosen the motor mount nuts (3). Lift or lower the motor (4)
until the pulleys are in line.
3. Tighten the motor mount nuts (3) using an adjustable wrench.
Motor
NOTE: To avoid rattles or other noise, the motor housing
should not touch the lower belt guard housing.
4. Retighten the belts by pulling the motor (4) toward the drill
press head, until the belt deflects approximately 1/2 inch
when pressed in the centre.
NOTE: Refer to the chart inside the belt guard cover for rec-
ommended drilling speeds and belt/pulley positions.
Fig. H
5. Lock the belt tension lock knobs (2) by turning clockwise.
NOTE: When the belts are new, it may be difficult to move the
belts. As the machine is used, the belts will gain more elastic-
ity and will be easier to adjust.

SQUARING TABLE TO HEAD (FIG. L)
1. Insert a 3" drill bit (1) into the chuck (2), tighten by turning
the chuck barrel counter clockwise.
2. Place a combination square (4) on the table (3) as shown.
The drill bit should be parallel to the straight edge of the
square.
3. If an adjustment is needed, loosen the bevel lock (5) with
a wrench.
4. Square the table to the bit by tilting the table.
5. Tighten the bevel lock when square.
