MAINTENANCE

WARNING:

When servicing, use only identical replacement parts.

Use of any other parts may create a hazard or cause

product damage.

WARNING:

Always wear safety goggles or safety glasses with side

shields during power tool operation or when blowing

dust. If operation is dusty, also wear a dust mask.

WARNING:

To prevent accidental starting that could cause possible

serious personal injury, turn off the tool, remove the

switch key, and unplug the drill press before performing

any maintenance or adjustment.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most

plastics are susceptible to damage from various types of

commercial solvents and may be damaged by their use. Use

clean cloths to remove dirt, dust, oil, grease, etc.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum-

based products, penetrating oils, etc., come in contact

with plastic parts. Chemicals can damage, weaken or

destroy plastic which may result in serious personal

injury.

After using the drill press, clean it completely and lubri-

cate all sliding and moving parts. Apply a light coat of

automotive-type paste wax to the table and column to help

keep the surfaces clean.

LUBRICATION

Lower spindle to maximum depth and oil moderately once

every three months.

Oil the column lightly every two months.

If cranking becomes difficult, grease gear rack lightly.

The ball bearings in the tool are permanently lubricated.

MOTOR/ELECTRICAL

The induction motor is easy to maintain but must be kept

clean. Do not allow water, oil, or sawdust to accumulate on

or in it. The sealed bearings are permanently lubricated and

need no further attention.

HEAD ASSEMBLY AND MOTOR HOUSING

Frequently blow out any dust that may accumulate inside

the head assembly and/or motor housing.

GEAR RACK

Periodically lubricate the worm gear and gear rack in order

to keep the vertical movement smooth and to help prolong

the life of the drill press.

REMOVING THE SPINDLE/CHUCK

The chuck tool is used to remove the chuck and/or spindle

when either an attachment is to be used or when large drill

bits with a tapered shank are to be used.

Unplug the drill press.

Lower the spindle until the slots in the spindle are

visible.

Insert the chuck tool into the spindle slot. While support-

ing the chuck in one hand, tap the chuck tool lightly with

a rubber mallet until the chuck and spindle release from

the drill press.

Remove the chuck tool from the spindle.
