WARNING:
When servicing use only identical Ryobi replacement
parts. Use of any other parts may create a hazard or cause
product damage.
WARNING:
To avoid serious personal injury make sure the drill press is
turned OFF and the cord is unplugged from the power
source before performing any maintenance or adjustment.
GENERAL MAINTENANCE
After using your 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.
HEAD ASSEMBLY
Frequently blow out any dust that may accumulate inside
the motor housing.
GEAR RACK
Periodically lubricate the gear rack in order to keep the
vertical movement smooth and to help prolong the life of your
drill press.
PULLEYS
See Figure 18.
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 seated and
tight, locate the set screw on the motor pulley and the hex
nut on the spindle pulley as shown in Figure 18. Tighten the
set screw with a hex wrench and the hex nut with an adjust-
able wrench.
Note: Turn hex nut counterclockwise to tighten.
CHUCK TOOL
The Chuck Tool is used to remove the chuck and chuck
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 slot in the spindle. While
supporting the chuck in one hand, tap the chuck tool lightly
with a rubber mallet until the chuck and chuck spindle release
from the drill press.
Remove the chuck tool from the drill press spindle.

LUBRICATION
The ball bearings in the quill and V-belt pulley are permanently
lubricated. To lubricate the spindle, pull quill down to
maximum depth and oil moderately once every three months.
Oil all slide bars lightly every two months. If cranking becomes
difficult, grease bracket lightly.
