When working with the tool outdoors, use an extension cord that is designed for outside use. This is indicated by the letters WA on the cord's jacket.

Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation. Repair or replace a damaged or worn cord immediately.

CAUTION:

Keep the cord away from the cutting area and position the cord so that it will not be caught on material, tools, or other objects during cutting.

ELECTRICAL CONNECTION

Your Ryobi Drill Press is powered by a precision built electric motor. It should be connected to a power supply that is 120

volts, 60Hz. If the machine does not operate when plugged into an outlet, double check the power supply.

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 a risk of electric shock. The conductor with 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.

TABLE ROTATION

When drilling large objects it may be necessary to swing the table out of the way. Simply loosen the table lock lever, rotate the table, and retighten table lock lever.

Note: When using the base as a work surface, the workpiece must be clamped securely to the base.

OPERATION

INSTALLING BITS

See Figure 16.

■ Unplug your drill press.

■ Open or close the chuck jaws to a point where the opening is slightly larger than the drill bit you intend to use.

■ Insert drill bit into chuck the full length of the jaws.

WARNING:

Do not insert drill bit into chuck jaws and tighten as shown in figure 16. This could cause drill bit to be thrown from your drill resulting in possible serious personal injury or damage to your chuck.

■ Tighten chuck jaws securely using the chuck key provided.

DO NOT use a wrench to tighten or loosen the chuck jaws.

■ Remove chuck key and return to storage area.

DRILLING

See Figure 17.

■ Using a C-clamp or similar clamping device, secure the workpiece to the work table. To protect the surface of the workpiece, use a piece of scrap between the clamp and the workpiece.

■ Select the proper drill bit based on the hole size desired.

For large holes, drill a pilot hole first, using a smaller diameter bit.

■ Set table assembly to desired height. If desired, set feed shaft at desired spindle depth.

■ Make sure the work table is free of all loose objects and that the bit is not in contact with the workpiece.

■ Plug electrical cord into power supply and turn switch ON.

Make sure spindle rotates freely.

■ Slowly lower drill bit into workpiece. Do not force the bit, let the drill press do the work.

■ Once the hole is completed, raise the spring-loaded feed shaft to its normal position. This will automatically raise the chuck and bit.

DRILLING TIPS

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.

EXTENSION CORD CAUTION

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.

Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.
