should unexpectedly shift.  
2. Always disconnect the tool from the power source when  
setting up, adjusting, or changing accessories.  
11. Never use your hand to hold the object while drilling.  
Always clamp the object tight on the work table or use a  
drill vise to prevent accidental injury.  
3. Do not wear gloves necktie, or loose clothing.  
4. Always clamp workpiece and brace against column to  
prevent rotation.  
12. Never perform any operation by moving the head or table  
with respect to one another. Do not turn the motor switch

ELECTRICAL  
GROUNDING INSTRUCTIONS  
In the event of a malfunction or breakdown, grounding  
provides a path of least resistance for electric current to  
reduce the risk of electric shock. This tool is equipped with  
an electric cord having an equipment-grounding conductor  
and a grounding plug. The plug must be plugged into a  
matching outlet that is properly installed and grounded in  
accordance with all local codes and ordinances.  
Do not modify the plug provided. If it will not fit the outlet,  
have the proper outlet installed by a qualified electrician.  
Improper connection of the equipment-grounding conductor  
can result in electrical shock. The conductor with the  
insulation having an outer surface that is green with or without  
yellow stripes is the equipment-grounding conductor. If repair  
or replacement of the electric cord or plug is necessary, do  
not connect the equipment-grounding conductor to a live  
terminal.

Check with a qualified electrician or service personnel if the  
grounding instructions are not completely understood, or if  
in doubt as to whether the tool is properly grounded.  
Repair or replace a damaged or worn cord immediately.  
This tool is intended for use on a circuit that has an outlet  
like the one shown in Figure 1. It also has a grounding pin  
like the one shown.

OPERATION  
WARNING:  
GENERAL INFORMATION  
Always remember to remove the chuck key from the table  
surface before turning on the drill press. Failure to heed  
this warning could result in serious personal injury.  
WARNING:  
Before performing any adjustment, make sure the drill  
press is unplugged from the power supply and the switch  
is in the OFF position. Failure to heed this warning could  
result in serious personal injury.  
WARNING:  
Do not attempt to operate this tool until you have read  
thoroughly and understand completely all instructions,  
safety rules, etc. contained in this manual. Failure to  
comply can result in accidents involving fire, electric shock,  
or serious personal injury. Save this operator’s manual  
and review it frequently for continuing safe operation and  
instructing others who may operate this tool.  
WARNING:  
Your drill press has a precision built electric motor. It should  
only be connected to a power supply that is 120 volts,  
60 Hz, AC only (normal household current). Do not  
operate this tool on direct current (DC). A substantial  
voltage drop will cause a loss of power and the motor will  
overheat. If your tool does not operate when plugged into  
an outlet, double check the power supply.  
WARNING:  
Before attempting to use your drill press familiarize  
yourself with all operating features and safety  
requirements.  
ON/OFF SWITCH KEY  
Your drill press is equipped with an on/off switch key. When  
removed, the switch key prevents the drill press from being  
turned on. The key must be in place to turn the drill press on.  
If the key is removed during operation, the drill press can be  
turned off but may not be turned on again until the key is  
replaced.  
OPERATING YOUR DRILL PRESS  
See Figures 16 and 17.  
1. Using a C-clamp or similar clamping device, secure the  
workpiece to the work table. To protect the top surface  
of the workpiece, use a piece of scrap between the clamp  
and the workpiece.  
ON/OFF SWITCH KEY  
2. Select the proper drill bit based on the hole size desired.  
For large holes, drill a pilot hole first, using a smaller  
diameter bit.  
Fig. 15  
SELF-EJECTING CHUCK KEY  
The self-ejecting chuck key ensures that the chuck key is  
removed from the chuck BEFORE the drill press is turned  
on.  
C-CLAMP  
In order to loosen or tighten the chuck using the chuck key,  
push the key into the chuck hole. You will feel the spring  
loaded key tighten. Rotate the key clockwise to tighten the  
chuck, counterclockwise to loosen the chuck. When you are  
finished with the chuck key, always replace it in the on-board  
chuck key storage located on the drill press head assembly.  
WARNING:  
Use only the self-ejecting chuck key provided. Always  
remove chuck key and store in the on-board chuck key  
storage. Failure to heed this warning could result in serious  
personal injury.

ON. Make sure spindle rotates freely.  
8. Slowly lower drill bit into workpiece. Do not force the bit,  
let the drill press do the work.  
5. Set table assembly to desired height. See page 11. If  
desired, set quill at desired spindle depth. See Depth  
Stop Adjustment on page 12.  
9. Once the hole is completed, allow the spring-loaded quill  
to return to its normal position. This will automatically  
raise the chuck and bit.  
DRILLING TIPS  
CHUCK  
KEY  
If the hole is large, it’s a good idea to drill a smaller pilot hole  
before drilling the final one. Your hole will be more accurately  
positioned, rounder, and the bits will last longer.  
If the hole is deeper than it is wide, back off occasionally to  
clear the chips. When drilling metal also use a coolant.  
As you increase the drill size, you may need to reduce the  
spindle speed.  
If drilling a through hole, make sure that the bit will not drill  
into the table after moving through your work.

MAINTENANCE  
Pulleys  
WARNING:  
When servicing use only identical Ryobi replacement  
parts. Use of any other parts may create a hazard or cause  
product damage.  
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 each of the pulleys as shown in  
Figure 18. Tighten each set screw with a 4 mm hex wrench.  
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.

Frequently blow out any dust that may accumulate inside  
the motor housing.  
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.  
Worm Gear and 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 your drill press.

When using a power tool at a considerable distance from a power  
source, be sure to use an extension cord that has the capacity to  
handle the current the tool will draw. An undersized cord will cause  
a drop in line voltage, resulting in overheating and loss of power.  
Use the chart to determine the minimum wire size required in an  
extension cord. Only round jacketed cords should be used.

When working with a tool outdoors, use an extension cord that is  
designed for outside use. This is indicated by the letters "WA" on  
the cord's jacket.  
CAUTION: Keep the extension cord clear of the working  
area. Position the cord so that it will not get caught on workpiece,  
tools, or other obstructions while you are working with a power  
tool.  
Before using any extension cord, inspect it for loose or exposed  
wires and cut or worn insulation.  
**Used on 12 gauge - 20 amp circuit.
