ELECTRICAL INFORMATION

GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance for an electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has 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 licensed electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The conductor with the green insulation (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 licensed electrician or service personnel if you do not completely understand the grounding instructions or whether the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that have three-pronged plugs and outlets that accept the tool's plug as shown in Fig. A. Repair or replace a damaged or worn cord immediately.


In all cases, make certain the outlet in question is properly grounded. If you are not sure, have a licensed electrician check the outlet.

This tool is for indoor use only. Do not expose to rain or use in damp locations.

GUIDELINES FOR USING EXTENSION CORDS
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The table below shows the correct size to be used according to cord length and nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.

Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected with a 15 A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a lower voltage will damage the motor.

This tool must be grounded while in use to protect the operator from electric shock.

ADJUSTING THE LASER (Fig. 15 and 16)

Do not stare directly at the laser beam. Please observe all safety rules.

• Never aim the beam at a person or an object other than the workpiece.
• Do not project the laser beam into the eyes of others.
• Always make sure the laser beam is aimed at a workpiece that does not possess reflective surfaces, as the laser beam could project into your eyes or the eyes of others.

1. Place a workpiece on the table.
2. Turn the laser switch (1) to the ON position.
3. Lower the drill bit to meet the workpiece (2). The two laser lines should cross where the drill meets the workpiece.

ANGULAR "PLAY" OF THE SPINDLE (Fig. 18)
Move the spindle to the lowest downward position and hold in place. Try to make the spindle revolve around its axis while also moving it with a side motion. If there is too much "play", proceed as follows:

REPLACING THE BELT (Fig. 19)


Disconnect the drill press from the power source before replacing the belt.
Belt tension and drill press speed is controlled by automatic adjustments made to the diameter of the front spindle when the drive handle is moved.
Note: See information on the variable speed function of this drill press.

1. Remove the screw that secures the housing cover (1). Open the housing cover.
2. Remove the belt (2) from the housing cover if it is broken. If it is not broken, but is too stretched to operate correctly, work the belt off the drive (motor) spindle (3). Then remove the belt from the front spindle (4).
3. Replace the belt by putting a new belt over the front spindle (4) and carefully sliding the belt over the drive (motor) spindle (3).

Do not change the drive speed when the drill press is turned off.

OPERATION

DRILL PRESS ON/OFF SWITCH (Fig. 20)

LIGHT AND LASER LINE ON/OFF SWITCHES (Fig. 20)
The light switch (3) is located on the lamp cover.
The laser switch (4) is located below the ON/OFF switch on the right.

POSITION THE TABLE AND WORKPIECE (Fig. 21)

Always place a piece of backup material (1) (wood, plywood, etc.) on the table underneath the workpiece (2). This will prevent splintering on the underside of the workpiece as the drill bit breaks through. To keep the material from spinning out of control, it must contact the left side (3) of the column as illustrated, or be clamped (4; not included) to the table.
Note: For small workpieces that cannot be clamped to the table, use a drill press vise (not included). The vise must be clamped or bolted to the table to avoid injury.

GENERAL DRILLING GUIDELINES - DRILLING A HOLE

To prevent the workpiece and the backup material from slipping from your hand while drilling, position the workpiece and backup material to the left side of the column. If the workpiece and the backup material are not long enough to reach the column, clamp the workpiece and backup material to the table. Failure to do this could result in personal injury.

1. Mark where you want to drill in workpiece by using a center punch or a sharp nail or turn ON the laser to mark your drilling point.
2. Before turning the drill press ON, turn the feed handles to bring the drill bit down. Line the drill bit tip up with the mark. Clamp the workpiece in place.
3. Turn ON the drill press and pull down on the feed handles with the appropriate force needed to allow the drill bit to drill the material.
   Note: Feeding too slowly might cause the drill bit to turn in the chuck. Feeding too rapidly might stop the motor, cause the belt to slip, force the workpiece loose, or break the drill bit. Practice with scrap material to get the feel of the machine before attempting to do any drilling operation.

ADJUST THE DRILLING DEPTH (Fig. 22)

The depth gauge controls the maximum distance the drill bit will move up or 1 down.
To stop the drill bit at a pre-measured depth, loosen the depth scale knob (1) by push button (2) until the bottom of the knob is aligned with the desired depth mark (3) on the gauge scale.
Drilling an unmeasured blind hole (not all the way through the workpiece) to a given depth can be done using either the depth scale method or the workpiece method.

DEPTH SCALE METHOD (Fig. 22)

1. Make sure the 0 (" or mm) mark on the depth gauge rests at the top edge of the metal support (4) when the quill is fully retracted.
2. Put the workpiece on the table and raise the table until the tip of the drill bit just touches the top of the workpiece. Lock the table in place.
3. Determine the drill depth for this workpiece.
4. Rotate the depth knob (2) until it is aligned with the desired depth mark (3) (for example, 1") on the gauge scale.
5. The chuck will be stopped at the distance selected on the depth scale.

WORKPIECE METHOD (Fig. 22 and 23)

1. Mark the desired depth (5) of the drill hole on the side of the workpiece.
2. With the drill press in the OFF position, bring the drill bit (6) down until the tip is even with the mark.
3. Holding the feed handles at this position, rotate the depth knob (2) until it meets the metal support.
4. The chuck and the drill bit will now be stopped at the distance selected on the depth scale.

DRILLING SPEEDS
There are a few important factors to keep in mind when determining the best drilling speed:

• Material type
• Hole size
• Drill bit or cutter type
• Quality desired

Smaller drill bits require greater speed than larger drill bits. Softer materials require greater speed than harder materials. See recommended speeds for particular materials.

DRILLING METAL

• Use metal-piercing twist drill bits.
• It is always necessary to lubricate the tip of the drill with oil to prevent overheating of the drill bit.
• All metal workpieces should be clamped down securely. Any tilting, twisting, or shifting causes a rough drill hole, and increases the potential of drill bit breakage.
• Never hold a metal workpiece with your bare hands. The cutting edge of the drill bit may seize the workpiece and throw it, causing serious injury. The drill bit will break if the metal piece suddenly hits the column.
• If the metal is flat, clamp a piece of wood under it to prevent turning. If it cannot be laid flat on the table, then it should be blocked and clamped.

DRILLING WOOD

• Brad point bits are preferred. Metal piercing twist bits may be used on wood.
• Do not use auger bits. Auger bits turn so rapidly that they can lift the workpiece off of the table and whirl it around.
• Always protect the drill bit by positioning the table so that the drill bit will enter the center hole when drilling through the workpiece.
• To prevent splintering, feed the drill bit slowly right as the bit is about to cut through to the backside of the workpiece.
• To reduce splintering and protect the point of the bit, use scrap wood as a backing or a base block under the workpiece.

FEEDING THE DRILL BIT

• Pull down on the feed handles with only enough force to allow the drill bit to cut.
• Feeding too rapidly might stall the motor, cause the belt to slip, damage the workpiece, or break the drill bit.
• Feeding too slowly will cause the drill bit to heat up and burn the workpiece.

MECHANICAL VARIABLE SPEED (Fig. 24)

This is a mechanical variable speed drill press. To increase or decrease the speed when operating, raise or lower the speed handle (1).
Use the following table to determine the recommended speed for the drill size you are using and the type of material you are to drill. While drilling, check the speed on the digital speed readout (2) located at the front of the drill press.

Do not change speed using variable speed handle without turning on the machine.

ADJUSTING THE MECHANICAL VARIABLE SPEED RANGE
To adjust the variable speed range from 280-1000 RPM to 1000-3300 RPM, first open the belt cover of the drill press. Loosen the spindles using the Lock Handle located on the right side of the drill press. Slide the belt into either Belt A-1 position or Belt B-2 position (seen below in the "Recommended Working Speeds" chart) depending on the RPM range needed. Retighten the spindles using the Lock Handle and then shut the belt cover.

Do not manually adjust belt position on the spindles when machine is on.

Recommended speed for drill bit size and materials

MAINTENANCE

For your safety, turn the switch off and remove the plug from the power supply before maintaining or lubricating the drill press.
Vacuum sawdust or metal shavings that accumulate in and on the motor, pulley housing, table, and work surface.
Apply a light coat of paste wax to the column and table to help keep these surfaces clean and rust-free.
The ball bearings in the spindle and the V-belt pulley assembly are greased and permanently sealed. Pull the spindle down and oil the spindle sleeve moderately every three months.
Lubricate the table bracket and locking knobs if they become difficult to use.

All servicing of the drill press should be performed by a qualified service technician.
