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 adjust-
ment.
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. Chemi-
cals 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 exposing the arbor.
Oil moderately once every three months.
[] Oil the column lightly every two months.
[] If turning 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.
PULLEYS
See Figure 26.
Should you feel an unusually high level of vibration, the
pulleys may not be tightly secured on the motor and/or
spindle shafts. To make sure the pulleys are properly seat-
ed and tight, locate the set screw on each of the pulleys.
Tighten each set screw with the hex key.
GEAR RACK
Periodically grease the worm gear and gear rack in
order to keep the vertical movement smooth and to help
prolong the life of the drill press.
