General Safety Rules

WARNING! Read and understand all instructions. Failure to follow

all instructions listed below may result in electric shock, fire and/or

serious personal injury.

SAVE THESE INSTRUCTIONS

WORK AREA

• Keep your work area clean and well lit. Cluttered benches and dark

areas invite accidents.

• Do not operate power tools in explosive atmospheres, such as in

the presence of flammable liquids, gases, or dust. Power tools

create sparks which may ignite the dust or fumes.

• Keep bystanders, children, and visitors away while operating a

power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Grounded tools must be plugged into an outlet properly installed

and grounded in accordance with all codes and ordinances.

Never remove the grounding prong or modify the plug in any way.

Do not use any adapter plugs. Check with a qualified electrician if

you are in doubt as to whether the outlet is properly grounded. If

the tools should electrically malfunction or break down, grounding

provides a low resistance path to carry electricity away from the user.

Applicable only to Class I (Grounded) tools.

• Double insulated tools are equipped with a polarized plug (one

blade is wider than the other.) This plug will fit in a polarized

outlet only one way. If the plug does not fit fully in the outlet,

reverse the plug. If it still does not fit, contact a qualified

electrician to install a polarized outlet. Do not change the plug in

any way. Double Insulation eliminates the need for the three wire

grounded power cord and grounded power supply system. Applicable

only to Class ll tools.

• Avoid body contact with grounded surfaces such as pipes,

radiators, ranges and refrigerators. There is an increased risk of

electric shock if your body is grounded.

• Don’t expose power tools to rain or wet conditions. Water entering

a power tool will increase the risk of electric shock.

• Do not abuse the cord. Never use the cord to carry the tools or

pull the plug from an outlet. Keep cord away from heat, oil, sharp

edges or moving parts. Replace damaged cords immediately.

Damaged cords increase the risk of electric shock.

• When operating a power tool outside, use an outdoor extension

cord marked “W-A” or “W.” These cords are rated for outdoor use

and reduce the risk of electric shock.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense

when operating a power tool. Do not use tool while tired or under

the influence of drugs, alcohol, or medication. A moment of

inattention while operating power tools may result in serious personal

injury,

• Dress properly. Do not wear loose clothing or jewelry. Contain

long hair. Keep your hair, clothing, and gloves away from moving

parts. Loose clothes, jewelry, or long hair can be caught in moving

parts.

• Avoid accidental starting. Be sure switch is off before plugging in.

Carrying tools with your finger on the switch or plugging in tools that

have the switch on invites accidents.

• Remove adjusting keys or wrenches before turning the tool on. A

wrench or a key that is left attached to a rotating part of the tool may

result in personal injury.

• Do not overreach. Keep proper footing and balance at all times.

Proper footing and balance enables better control of the tool in

unexpected situations.

• Use safety equipment. Always wear eye protection. Dust mask,

1

English

non-skid safety shoes, hard hat, or hearing protection must be used for

appropriate conditions.

TOOL USE AND CARE

• Use clamps or other practical way to secure and support the

workpiece to a stable platform. Holding the work by hand or against

your body is unstable and may lead to loss of control.

• Do not force tool. Use the correct tool for your application. The

correct tool will do the job better and safer at the rate for which it is

designed.

• Do not use tool if switch does not turn it on or off. Any tool that

cannot be controlled with the switch is dangerous and must be

repaired.

• Disconnect the plug from the power source before making any

adjustments, changing accessories, or storing the tool. Such

preventive safety measures reduce the risk of starting the tool

accidentally.

• Store idle tools out of reach of children and other untrained

persons. Tools are dangerous in the hands of untrained users.

• Maintain tools with care. Keep cutting tools sharp and clean.

Properly maintained tools, with sharp cutting edges are less likely to

bind and are easier to control.

• Check for misalignment or binding of moving parts, breakage of

parts, and any other condition that may affect the tools operation.

If damaged, have the tool serviced before using. Many accidents

are caused by poorly maintained tools.

• Use only accessories that are recommended by the manufacturer

for your model. Accessories that may be suitable for one tool, may

become hazardous when used on another tool.

SERVICE

• Tool service must be performed only by qualified repair

personnel. Service or maintenance performed by unqualified

personnel could result in a risk of injury.

• When servicing a tool, use only identical replacement parts.

Follow instructions in the Maintenance section of this manual.

Use of unauthorized parts or failure to follow Maintenance Instructions

may create a risk of electric shock or injury.

Additional Safety Instructions

• Always use safety strap. Mounting can release. Electrical power

may fail or unit may accidentally disconnect.

• Always be sure that the drill press is plugged into the correct

voltage system. Place cord so that it cannot be pulled from the

receptacle accidentally. Check for correct line fuse.

• Before operating unit, make sure it is grounded correctly in

accordance with instructions under “Electrical Safety.”

• Always use the correct gauge extension cord .

• Care should be taken to place the base on a flat surface. Do

not set magnet on objects such as bolt heads, screws, rivets, or

steel chips, since space between magnet and working surface

weakens the magnetic pull.

• Always place the unit on a surface that is clear of shavings,

chips or surface dirt to allow for optimum magnetic hold.

CAUTION: Wear appropriate personal hearing protection during

use. Under some conditions and duration of use, noise from this

product may contribute to hearing loss.

CAUTION: DO NOT USE FEED HANDLE TO LIFT UNIT.

CAUTION: After switching power to the magnet off, the magnetic

base will continue to adhere to the surface for 5 seconds before

releasing. A light blow with the hand will release the base.

WARNING: Some dust created by power sanding, sawing, grinding,

drilling, and other construction activities contains chemicals known to

cause cancer, birth defects or other reproductive harm. Some

examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry

products, and

• arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you

do this type of work. To reduce your exposure to these chemicals:

work in a well ventilated area, and work with approved safety

equipment, such as dust masks that are specially designed to filter

out microscopic particles.

• Avoid prolonged contact with sawdust from treated lumber. Do

not allow dust to get into your mouth, eyes or lay on the skin. Wear

protective clothing whenever possible.

• The label on your tool may include the following symbols.

Motor

Your DEWALT tool is powered by a DEWALT-built motor. Be sure your

power supply agrees with the nameplate marking.

Volts 60 Hz or “AC only” means your tool must be operated only with

alternating current and never with direct current.

Voltage decrease of more than 10% will cause loss of power and

overheating. All D

EWALT tools are factory tested; if this tool does not

operate, check the power supply. If the motor does not operate when

the green button is pushed, check the voltage at the power supply.

Operation

The magnet in this unit is designed for use on 3/8"(10mm) thick

steel—with zero air gap. Air gap may be defined as the distance

English

606564/DW151 10/1/02 10:20 AM Page 2

between the magnet core surface and the mounting plate. The two

surfaces will be kept apart by curvature, coats of paint, by surface

irregularities, bolt heads, etc. Holding power is reduced by rough or

uneven surfaces, insufficient thickness of steel or insufficient

mounting area for the magnet base. The

magnet rapidly loses its holding power when

this surface irregularity raises the air gap above

1/64"(.4mm). Keep this air gap to a minimum

and be sure to smooth the surface removing

any undue projections, chips or other items that

will not allow full metal to metal contact. If the

magnet fails to hold on a metal surface, it may

be due to this condition and a check can be

made with a feeler gauge or similar device in

order to determine if an air gap exists under the

magnet at the crucial points.

1. Place drill press on work surface so that drill

point or cutter pilot is directly over spot to be drilled. Push the red

button (A) to give power to the tool. Position the cutter directly over

the spot to be drilled and turn the magnet on by pressing the

yellow button (B). Turn power on to the motor by pressing the

green button (C). When drilling in an overhead or vertical position,

the safety strap (D) must be employed.

(Fitted in slot in base as shown)

NOTE: Replace strap if edges become frayed.

Inspect the strap before each use. New straps

are available at your retailer or D

EWALT service

center.

2. Gently apply pressure to feed handle until twist

drill or cutter has a full bite then apply steady

pressure until cut is complete.

3. Turn off motor and allow motor to run down

3

English

before turning magnet off.

4. Turn magnet off by pressing the yellow button. The magnet will

remain engaged for 5 seconds before releasing.

5. After each use, remove all chips from

magnet surface.

Operation with DEWALT

Annular Cutters

1. This unit was designed with user

convenience and safety in mind

2. User safety:

The switches are arranged to prevent

accidental motor start up before the magnet is energized.

The handles are arranged to allow for easy vertical and overhead

placement.

3. This unit comes equipped with a quick release feed handle (E). By

depressing a button, the feed handle can be

switched from the left to the right side of the unit.

The magnet is designed to adhere to 3/8”(10mm)

or greater thickness of flat steel or iron.

NOTE: DW151 can be adapted for use with twist

drill bits with addition of DW1561 Chuck Adapter.

4. Place proper pilot pin into desired cutter from the

top and insert cutter into the arbor. Line up cutter

flats with arbor set screws. Tighten both set

screws securely. (Make sure flats are properly

located under set screws so that they remain

recessed below surface of the shaft).

5. Fill reservoir with non oil-based cutting fluid. This

fluid is formulated to give the best performance

and life to the rotary cutters. Fluid will be released down pilot shaft

by gravity feed. Test by running cutter up and down against work

surface to start fluid flowing. Do not use liquid cutting fluids while

A

drilling vertically or overhead. Dip cutter in cutting paste for these

applications..

NOTE: This unit features an on-board lubrication system. To use

the lubrication system, remove the hose (F) from the bottle by

depressing the black collar (G) into the bottle. Remove the hose

from the bottom of the petcock. Remove the bottle from the

bracket and fill with cutting fluid. Replace bottle in bracket and

replace hose. Turn the petcock counterclockwise to start the fluid.

Turn the petcock clockwise to close the valve when the cut is

finished. The bearings are lubricated by the on-board system.

WARNING: Do not pour cutting fluid into the bottle while

mounted in the bracket. Do not allow cutting fluid to enter the

drill motor. Electric shock may result.

6. Start motor by pressing the green button.

7. Bring cutter lightly to the surface to be cut allowing 25-30

revolutions, bringing up light chip so that cutter has established an

external groove. This will position you properly. Apply steady

pressure through the entire cut. It is more important to keep rpms

up than to apply excessive force, causing cutter to slow motor

down. This will attain better cutting action, better cutter life, and

cleaner holes.

8. Slug should be expelled on the down stroke. If not, it will be

expelled automatically when motor is returned to the extreme up

position.

CAUTION: Gloves should be worn when handling slugs to avoid

injury to the hand by hot surfaces or sharp edges.

Operation of Swivel Base (DW159)

1. Place unit on work surface sot that the point is near the center of

the hole to be drilled.

2. Push the red button to turn power on.

3. Push the yellow button to activate magnet.

English

4. Turn lever (H) counterclockwise to loosen the

swivel base.

5. Move the drill and rotate about the magnet

until the pilot pin is directly above the center

of the hole to be drilled.

6. Turn lever clockwise to tighten the swivel.

Operation of the Forward/Reverse

Feature (DW159)

The forward/reverse switch is a collar (I) on the top of the drill unit of

the DW159 only.

Control

Apply sufficient pressure to achieve a smooth, progressive cut. Do

not force unit. If magnet starts to lift from work plate, decrease

pressure slightly and it will reclamp. Drill point pressure may exceed

holding power under one or more of the following conditions:

1. Excessive air gap—1/64"(.4mm) or more.

2. Thin metal (under 3/8"(10mm) depending upon position and

condition of metal surface.)

3. Metal with low magnetic properties.

4. Uneven or rough surface.

5. Low line voltage.

How To Drill

For accuracy drill a small lead hole before using the final size drill.

Large diameter drills will “walk” off center until drill reaches full

diameter at which point the outside diameter acts as a pilot in the

hole being drilled. This is not peculiar to magnetic drill presses, but

is general machine shop knowledge on any large hole drilling.

Brushes

Carbon brushes should be regularly inspected for wear. When the

cap is unscrewed, the spring and brush assembly may be withdrawn

from the tool.

Keep brushes clean and sliding freely in their guides. Carbon

brushes have varying symbols stamped into them, and if the brush

is worn down to the line closest to the spring, they must be replaced.

New brush assemblies are available at service centers.

Adjustments

This unit is designed with a lubricated gib and is adjusted at the factory.

The gib may by lubricated periodically with grease to ensure smooth

operation. The gib should be tight enough to retain the motor in the

upward (retracted) position. Should this need adjustment, tighten 5

self-locking set screws on the side of the drill press body.

Accessories

Recommended accessories for use with your tool are available at

extra cost from your distributor or your local service center.
