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.

• 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.

• DIRECTION OF FEED FOR DRUM SANDING. Feed

work-piece into a sanding drum, or other approved

accessory, against the direction of rotation.

• Sanding drums are a very useful accessory, but the arbor

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.

• Drum sanders must be operated at a speed under

1000rpm.

• For hole cutters keep speed below 800rpm.

TERMS:

THROAT DEPTH: Distance between the center of the

spindle (where the bit goes) and front edge of the column.

SPINDLE TRAVEL: Movement up and down of the spindle,

which determines the maximum depth of the hole one can

bore.

MAINTENANCE

(PERFORM ALL MAINTENANCE WITH DRILL PRESS

UNPLUGGED.)

Clean after use T-slots, grooves, and dirt from belts and

pulleys. Remove chips to avoid damage to moving parts.

Wipe all spindles and sleeves free of grit to avoid damaging

the precision fit.

If operated under extremely dusty conditions, operate at the

slowest speeds to avoid rapid abrasive wear on the moving

parts and lubricate the machines more often. Under extreme

cold conditions, start at a slow speed and allow the parts

and lubricants to warm up before increasing the speeds.

To assure product SAFETY and RELIABILITY, repairs,

maintenance and adjustment (including brush inspection

and replacement) should be performed by authorized

service centers or other qualified service organizations,

always using identical replacement parts.
