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 lubricate 
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.
