shaft and place the drill chuck on the drill spindle.
Warning! Clean the drill chuck and the drill spindle
thoroughly so that they are completely free of grease.
Installing and Adjusting
Perform all adjustments with the drill press unplugged
Testing the Belt (Fig. 2)
Loosen the attachment screw (wing screw) on the right
side of the motor. Push back the motor base and tighten
the attachment screw. The proper tension has been
achieved when the V-belt can be pressed in approximately
1 cm in the middle between the two belt discs.
Speed Adjustment (Fig. 3)
The drill press has 5 speed settings which can be set by
simply adjusting the V-belt. To set the speed, first remove
the gear cover and loosen the attachment screw. Slide
the belt onto the desired belt discs. The upper discs will
provide the highest speed and the lower discs the lowest.
Tense the belt according as per the testing belt procedure.
Table Adjustment (Fig. 4)
The table is fastened to the support column. The height
of the table can be set after the height adjustment lever
has been loosened for this purpose. Adjust the table so
that there is sufficient space between the tip of the drill bit
and the surface of the material to be worked. The table
can be swung to the side when working with a large piece
material. The material can be clamped directly onto the
base on the tool.
OPERATION
Plug the drill press into any power source. Refer to the
nameplate for voltage. Be sure the cord will not interfere
with your work.
Warning! Perform all adjustments with the drill press
unplugged
Once you have assembled the press and everything is
tight and aligned you need to see if there is a wobble. Put
the largest diameter bit (make sure it is perfectly straight)
you have into the chuck and snug it up. Run the drill press
at its lowest speed and see if the edge of the bit right at
the tip is moving side to side. If you see movement you
need to determine why. You've already checked the bit,
so now reseat it in the chuck and try again. If there is still
movement, remove the chuck and arbor from the drill
press. Carefully clean both tapers of the arbor and the
taper holes of the chuck and press. As you reassemble
check if there is wobble on the arbor alone. If there was
no wobble with the arbor alone but there was with the
chuck, then you need to exchange the chuck. If there was
a wobble without the chuck it is either the arbor or the drill
press shaft itself.
Drilling Depth (Fig. 5)
The drilling depth can be set sharply using the depth scale.
Lower the drill bit using the drill lever arms until the tip of
the bit presses lightly against the surface of the material to
be worked. Set the drilling depth by turning the adjustment
depth. Be sure to consider the length of the bit tip as well
as the length of the cylindrical part of the hole to be drilled.
To avoid heat build up when drilling deep holes, reduce
the friction by occasionally lifting the spinning bit free of
the work-piece to allow chip removal, then re inserting it to
cut deeper.
Offset Drilling (Fig. 6)
The table can be tilted for offset drilling or in the case of
slanted drilling surfaces. To do this, loosen the hexagonal
bolt on the hinge connecting the table to the support
column using a fork wrench. Tilt the table into the desired
position and retighten the hexagonal bolt.
Warning! A kickback occurs when work-piece suddenly
binds on the cutting edge of the tool and the work-piece is
thrown by the cutter in the direction of the cutter's rotation.
This can cause serious injury. It is important the work-
piece is securely clamped or held down before drilling.
Chuck Guard
It provides protection from quill to drill point allowing a smooth
telescopic action as the drill penetrates the work-piece.
Accessories:
Caution! The use of any non-recommended accessory
such as dado sets, molding cutters or abrasive wheels
may be hazardous. Make sure you have attached the
accessory properly and it is run within the specs of both
the press and attachment.
f Do not install or use any drill bit that exceeds 7" in
length or extends 6" below the chuck jaws. They could
suddenly bend outward or break.
f Direction of feed for drum sanding. Feed work-piece
into a sanding drum, or other approved accessory,
against the direction of rotation.
f Sandingdrumsareaveryusefulaccessory,butthearbor
of a drill press is not designed for sideways pressure.
Don't push too hard when sanding, this could transfer
a great deal of stress to the shaft.
f Drum sanders must be operated at a speed under
1000rpm.
f For hole cutters keep speed below 800rpm.

f Throat depth: Distance between the center of the
spindle (where the bit goes) and front edge of the
column.
