Important Safety Instructions for Battery Packs

Your tool uses a 9.6, 12.0, 14.4 or an 18 Volt DEWALT battery pack. When ordering replacement battery packs, be sure to include catalog number and voltage. Extended Run-Time battery packs deliver more

English

run-time than standard battery packs. Consult the chart at the end of this manual for compatibility of chargers and battery packs.

NOTE: Your tool will accept either standard or Extended Run Time battery packs. However, be sure to select proper voltage. Batteries slowly lose their charge when they are not on the charger, the best place to keep your battery is on the charger at all times.

The battery pack is not fully charged out of the carton. Before using the battery pack and charger, read the safety instructions below. Then follow charging procedures outlined.

READ ALL INSTRUCTIONS

• Do not incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in

a fire.

• A small leakage of liquid from the battery pack cells may occur under extreme usage or temperature conditions. This does not indicate a failure. However, if the outer seal is broken and this leakage gets on your skin:

a. Wash quickly with soap and water. b. Neutralize with a mild acid such as lemon juice or vinegar. c. If battery liquid gets into your eyes, flush them with clean water

for a minimum of 10 minutes and seek immediate medical attention. (Medical note: The liquid is 25-35% solution of potassium hydroxide.)

• Charge the battery packs only in D

EWALT chargers.

• DO NOT splash or immerse in water or other liquids.

• Do not store or use the tool and battery pack in locations where the temperature may reach or exceed 105°F (40˚) (such as outside sheds or metal buildings in summer).

DANGER: Electrocution hazard. Never attempt to open the battery

pack for any reason. If battery pack case is cracked or damaged, do not insert into charger. Electric shock or electrocution may result. Damaged battery packs should be returned to service center for recycling.

NOTE: Battery storage and carrying caps are provided for use whenever the battery is out of the tool or charger. Remove cap before placing battery in charger or tool.

WARNING: Do not store or carry battery so that

metal objects can contact exposed battery terminals.

For example, do not place battery in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc. without battery cap. Transporting batteries can possibly cause

fires if the battery terminals inadvertently come in contact with conductive materials such as keys, coins, hand tools and the like. The US Department of Transportation Hazardous Material

Regulations (HMR) actually prohibit transporting batteries in commerce or on airplanes (i.e., packed in suitcases and carry-on luggage) UNLESS they are properly protected from short circuits. So when transporting individual batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit.

The RBRC™ Seal

The RBRC™ (Rechargeable Battery Recycling Corp oration) Seal on the nickel-cadmium battery (or battery pack) indicates that the costs to recycle the battery (or battery pack) at the end of its useful life have already been paid by D

EWALT. In some areas, it is illegal to place spent nickel-

cadmium batteries in the trash or municipal solid waste stream and the RBRC program provides an environmentally conscious alternative.

RBRC in cooperation with D

EWALT and other battery users, has

established programs in the United States to facilitate the collection of spent nickel-cadmium batteries. Help protect our environment and conserve natural resources by returning the spent nickel-cadmium battery to an authorized D

EWALT service center or to your local retail-

er for recycling. You may also contact your local recycling center for information on where to drop off the spent battery.

RBRC™ is a registered trademark of the

Important Safety Instructions for Battery Chargers

SAVE THESE INSTRUCTIONS: This manual contains important safety instructions for battery chargers.

• Before using charger, read all instructions and cautionary markings on charger, battery pack, and product using battery pack.

DANGER: Electrocution hazard. 120 volts are present at charging

terminals. Do not probe with conductive objects. Electric shock or electrocution may result.

WARNING: Shock hazard. Do not allow any liquid to get inside

charger. Electric shock may result.

CAUTION: Burn hazard. To reduce the risk of injury, charge only

EWALT nickel cadmium rechargeable batteries. Other types of bat-

teries may burst causing personal injury and damage.

CAUTION: Under certain conditions, with the charger plugged in to

the power supply, the exposed charging contacts inside the charger can be shorted by foreign material. Foreign materials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug charger before attempting to clean.

• DO NOT attempt to charge the battery pack with any chargers other than the ones in this manual. The charger and battery pack are specifically designed to work together.

• These chargers are not intended for any uses other than

charging D

EWALT rechargeable batteries. Any other uses may

result in risk of fire, electric shock or electrocution.

• Do not expose charger to rain or snow.

• Pull by plug rather than cord when disconnecting charger. This will reduce risk of damage to electric plug and cord.

• Make sure that cord is located so that it will not be stepped on,

tripped over, or otherwise subjected to damage or stress.

• Do not use an extension cord unless it is absolutely necessary. Use of improper extension cord could result in risk of fire,

electric shock, or electrocution.

• An extension cord must have adequate wire size (AWG or American Wire Gauge) for safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is 16 gauge has more capacity than 18 gauge. When using more than one extension to make up the total length, be sure each individual extension contains at least the minimum wire size.

er on a soft surface that might block the ventilation slots and result in excessive internal heat. Place the charger in a position

away from any heat source. The charger is ventilated through slots in the top and the bottom of the housing.

• Do not operate charger with damaged cord or plug — have them replaced immediately.

• Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way. Take it to an authorized service center.

• Do not disassemble charger; take it to an authorized service center when service or repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or fire.

• Disconnect the charger from the outlet before attempting any cleaning. This will reduce the risk of electric shock. Removing the battery pack will not reduce this risk.

• NEVER attempt to connect 2 chargers together.

• The charger is designed to operate on standard household

electrical power (120 Volts). Do not attempt to use it on any other voltage. This does not apply to the vehicular charger.

English

Using Automatic Tune-Up™ Mode

The Automatic Tune-Up™ Mode equalizes or balances the individual cells in the battery pack allowing it to function at peak capacity. Battery packs should be tuned up weekly or after 10 charge/discharge cycles or whenever the pack no longer delivers the same amount of work. To use the Automatic Tune-Up™, place the battery pack in the charger and leave it for at least 8 hours. The charger will cycle through the following modes.

1. The red light will blink continuously indicating that the 1-hour charge cycle has started.

2. When the 1-hour charge cycle is complete, the light will stay on continuously and will no longer blink. This indicates that the pack is fully charged and can be used at this time.

3. Whenever the pack is left in the charger after the initial 1-hour charge, the charger will begin the Automatic Tune-Up™ Mode. This mode continues up to 8 hours or until the individual cells in the battery pack are equalized. The battery pack is ready for use and can be removed at any time during the Tune-Up™ Mode.

4. Once the Automatic Tune-Up™ Mode is complete the charger will transition to a maintenance charge; the indicator light shuts off when the Automatic Tune-Up™ Mode is complete.

Chargers

Your tool uses a 7.2, 9.6, 12.0, 14.4, or 18.0 Volt DEWALT charger. Your battery can be charged in D

EWALT 1 Hour Chargers, 15 Minute

Chargers or Vehicular 12 Volt Charger. Be sure to read all safety instructions before using your charger. Consult the chart at the end of this manual for compatibility of chargers and battery packs.

Charging Procedure

DANGER: Electrocution hazard. 120 volts present at charging ter-

minals. Do not probe with conductive objects. Danger of electric shock or electrocution.

1. Plug the charger into an appropriate outlet before inserting battery pack.

2. Insert the battery pack into the charger making sure the pack is fully seated. The red (charging) light will blink continuously indicating that the charging process has started.

3. The completion of charge will be indicated by the red light remaining ON continuously. The pack is fully charged and may be used at this time or left in the charger.

Indicator Light Operation

Charge Indicators

Some chargers are designed to detect certain problems that can arise with battery packs. Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery pack into the charger. If the problem persists, try a different battery pack to determine if the charger is OK. If the new pack charges correctly, then the original pack is defective and should be returned to a service center or other collection site for recycling. If the new battery pack elicits the same trouble indication as the original, have the charger tested at an authorized service center.

HOT/COLD PACK DELAY

Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a battery that is hot, it automatically starts a Hot Pack Delay, suspending charging until the battery has cooled. After the battery has cooled, the charger automatically switches to the Pack Charging mode. This feature ensures maximum battery life. The red light flashes long, then short while in the Hot Pack Delay mode.

English

PROBLEM POWER LINE

Some chargers have a Problem Power Line indicator. When the charger is used with some portable power sources such as generators or sources that convert DC to AC, the charger may temporarily suspend operation, flashing the red light with two fast blinks followed by a

pause. This indicates the power source is out of limits. LEAVING THE BATTERY PACK IN THE CHARGER

The charger and battery pack can be left connected with the red light glowing indefinitely. The charger will keep the battery pack fresh and fully charged.

NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery pack has not been kept on maintenance charge, it may need to be recharged before use. A battery pack may also slowly lose its charge if left in a charger that is not plugged into an appropriate AC source.

WEAK BATTERY PACKS: Chargers can also detect a weak battery. Such batteries are still usable but should not be expected to perform as much work. In such cases, about 10 seconds after battery insertion, the charger will beep rapidly 8 times to indicate a weak battery condition. The charger will then go on to charge the battery to the highest capacity possible.

Important Charging Notes

1. Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65°F and 75°F (18°- 24°C). DO NOT charge the battery pack in an air temperature below +40°F (+4.5°C), or above +105°F (+40.5°C). This is important and will prevent serious damage to the battery pack.

2. The charger and battery pack may become warm to touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed, or an uninsulated trailer.

3. If the battery pack does not charge properly: a. Check current at receptacle by plugging in a lamp or other

appliance

b. Check to see if receptacle is connected to a light switch which

turns power off when you turn out the lights.

c. Move charger and battery pack to a location where the sur-

rounding air temperature is approximately 65°F - 75°F (18°24°C).

d. If charging problems persist, take the tool, battery pack and

charger to your local service center.

4. The battery pack should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the charging procedure. You may also charge a partially used pack whenever you desire with no adverse affect on the battery pack.

5. Under certain conditions, with the charger plugged into the power supply, the exposed charging contacts inside the charger can be shorted by foreign material. Foreign materials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug charger before attempting to clean.

6. Do not freeze or immerse charger in water or any other liquid.

WARNING: Shock hazard. Don’t allow any liquid to get inside

charger. Electric shock may result.

CAUTION: Never attempt to open the battery pack for any reason.

If the plastic housing of the battery pack breaks or cracks, return to a service center for recycling.

CHARGER CLEANING INSTRUCTIONS

WARNING: Shock hazard. Disconnect the charger from the AC

outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions.

al, in addition to the wall mount clamp, to help secure the laser level while mounting it to a wall. Thread the wire through the holes in the roll cage above the Rack 'N Pinion Adjustment Knob (C) or above the Rack 'N Pinion Locking Knob (D). Additionally, screws or nails can be used to fasten the tool directly to the wall as a back up. Screw/Nail holes (B) are located in the Base Plate next to the Base Plate Measuring Scales.

4. The tool can be adjusted up and down to the desired offset height for working. To change the height, loosen the Rack 'N Pinion Locking Knob (D) located to the left of the laser head.

TIP:

You may need to support the weight of the tool while the Rack 'N Pinion Locking Knob is loosened. Turn the Rack 'N Pinion Adjustment Knob (C) located to the right of the laser head to move the laser level up and down to set your height. Use the Base Plate Measuring Scale to pinpoint your mark.

TIP:

It may be helpful to turn the power ON and spin the rotary head to set your height. Once you have positioned the laser at your desired offset height, tighten the Rack 'N Pinion Locking Knob to maintain your mark.

5. Use the Base Leveling Knob (behind the battery) at the bottom of the base plate to aid in positioning the tool against the wall.

English

6. Follow the instructions for leveling the laser.

TIP:

Remember the front leveling knob controls the movement of the bubble in the front vial, the side leveling knob controls the movement of the bubble in the side vial.

7. Turn the laser on if not on already; adjust rotation speed and controls as needed.

Horizontal Leveling

1. Set the laser on a relatively smooth and level surface such as a Tripod or prepare the laser level to be attached to wall track using the built-in Wall Mount feature. See “Wall Mount” section.

2. Use the Two-Position Pivoting Head Adjustment Lever to pivot the laser head to a level setting for projecting a horizontal reference beam. In this position the Manual Head Rotation Button (A) should be pointing up towards the ceiling or sky.

3. The leveling knobs (B) control the orientation of the laser head on the metal leveling plates and effect the movement of the bubbles in the vials (C). When the laser level is placed in a level position the front leveling knob controls the movement of the bubble in the front vial. The side leveling knob controls the movement of the bubble in the side vial. NOTE: The same leveling rules apply to the tool when being used with the Wall Mount feature.

4. To level the laser, the bubbles in both the front and side vials need to be centered within the vials.

TIP:

The more accurately you can center the bubbles within the vials the more accurate your horizontal laser reference beam will be.

5. To level the laser, turn the leveling knob towards the bubble until the bubble is centered in the vial.

TIP:

To move the bubble in the

front vial to the right, turn the front leveling knob to the left. To

move the bubble in the front vial to the left, turn the leveling knob to the right. Repeat the procedure for the side vial.

6. Turn the laser on if not on already; adjust rotation speed and controls as needed.

7. To project a level laser reference plane, adjust the rotation speed for preferred visibility. Remember: Slow Speed = Bright Beam; Fast Speed = Solid Beam.

Vertical Plumbing

1. Set the laser on a relatively smooth and level surface. The tool should be positioned on the large base plate under the battery pack. Utilize the Base Leveling Knob (A) to roughly position the laser.

2. Use the Two-Position Pivoting Head Adjustment Lever to pivot the laser head to a plumb setting for projecting a vertical reference beam. In this position the pivoting laser head should be directly over the Wall Mount Clamp and the Control Panel should be facing up towards the ceiling or sky.

3. To plumb the laser, only the bubble in the Plumb Vial (D) needs to be centered.

TIP:

The more accurately you can position the bubble within the vial the more accurate your vertical laser reference beam will be.

4. Looking over the top of the laser, turn the Plumb Leveling Knob (B) (which is located on the side of the pivoting laser head in this orientation) to move the bubble within the Plumb Vial (D). Turn the plumb leveling knob towards the bubble until the bubble is centered in the vial.

TIP:

Turn the knob in the opposite direction you

need the bubble to move.

5. Use the Plumb Beam Alignment Knob (C )(which is the knob next to the Plumb Vial) to adjust the plumb laser reference plane over your mark.

English

6. Turn the laser on if not on already; adjust rotation speed and controls as needed.

7. To project a plumb laser reference plane, adjust the rotation speed for preferred visibility. Remember: Slow Speed = Bright Beam; Fast Speed = Solid Beam.

Manual Head Rotation Button

The laser has been designed with a protective cap over the rotary head to prevent accidental damage from work site activities. You can still access the rotary head and manually direct the beam to establish or transfer a mark. To manually rotate the laser beam follow the instructions below.

If the laser is turned OFF, rotate the ON/OFF knob clockwise a 1/4 turn or less. Ensure that the laser diodes are powered on and that the rotary head is not spinning. If the laser is ON and spinning, rotate the ON/OFF knob counterclockwise until rotation of the head stops.

Depress the spring loaded Manual Head Rotation Button (A) on the top of the protective cap. The button will make contact with the rotary laser head. While maintaining pressure on the Manual Head Rotation Button, you can now turn the button and direct the laser beams in the direction of your mark.

Since the laser has been designed with dual, side by side laser diodes, you may see 2 laser dots on the object you are projecting the beam onto. Marks can be made using either laser dot. Mark the center of the dot.

DO NOT attempt to use the Manual Head Rotation Button while the rotary head is spinning.

While using the Manual Head Rotation Button, it is recommended that you set the Bump Sensor to Setting 1. See Bump Sensor operation.

NOTE: After storing this product in extremely cold conditions, the laser head may not immediately rotate when turned on. The rotary head may be started by depressing and turning the Manual Rotation Button counterclockwise.

Laser Enhancement Glasses

The DEWALT Laser Kit includes a pair of Laser Enhancement Glasses. These red lens glasses improve the visibility of the laser beam under bright light conditions or over long distances. These glasses are not required to operate the laser but are helpful. Working best indoors, the lens filters out ambient light and intensifies the red laser dot or line to your eyes.

CAUTION: These glasses are not ANSI approved safety glasses

and should not be worn while operating other tools. These glasses do not keep the laser beam from entering your eyes.

DANGER: NEVER STARE DIRECTLY INTO THE LASER BEAM,

WITH OR WITHOUT THESE GLASSES.

Target Card

The DEWALT Rotary Laser Kit includes a Laser Target Card to aid in locating and marking the laser beam. The target card enhances the visibility of the laser beam as the beam crosses over the card. The card is marked with inch and metric scales. The laser beam passes through the red plastic and reflects off of the reflective tape on the reverse side. The magnets at the top hold the target card to ceiling track or steel studs to determine plumb and level positions.

Digital Laser Detector

The DEWALT Digital Laser Detector enables you to locate a laser beam emitted by a Rotary Laser in bright light conditions or over long distances. The detector can be used in both indoor and outdoor situations where it is difficult to see the laser beam. The detector is not for use with non-rotating lasers.

The detector gives both visual and audio signals as to the location of the laser beam as the beam crosses over the detector. The D

EWALT

Digital Laser Detector is compatible with most rotary lasers on the

English

market today. The clamp attaches the Digital Laser Detector to grade rods, leveling poles, wall studs or posts. The detector can also be mounted to ceiling track by attaching the magnets on the top of the detector to the track.

If this laser kit contains a D

EWALT Digital Laser Detector, a separate

instruction manual has been included. For proper use and operation read and understand the Detector manual before use.

Maintenance

• To maintain the accuracy of your work, have the laser checked often to make sure it is properly calibrated.

• Calibration checks and other maintenance repairs can be performed by D

EWALT service centers. Two free calibration checks

are included under the D

EWALT One Year Free Service Contract.

• When not in use, store the laser in the kit box provided.

• Do not store your laser in the kit box if the laser is wet. Allow laser to air dry and dry exterior parts with a soft dry cloth.

• Do not store your laser at temperatures below 0˚ F or above 105˚F.

CLEANING: Exterior plastic parts may be cleaned with a damp

cloth and mild detergent. Although these parts are highly solvent resistant, NEVER use solvents. Use a soft dry cloth to remove moisture from tool and accessories before storage. Never use compressed air to clean the laser.

Field Calibration Check

This section provides instructions by which you can perform simple field calibration checks of your D

EWALT Rotary Laser. These checks

cannot take the place of professional calibration done by a D

EWALT

service center. These instructions will help you check for the three types of out-of-

level errors.

• Tilt Error - checks that rotation of the head in your Rotary Laser

is perfectly level.

• Cone Error - checks that the laser beams are not at an angle

relative to the level head.

• Plumb Error - checks the calibration of the plumb leveling vial.

TILT ERROR CHECKS

Horizontal Checking for Front to Back Tilt Error

• Set up a tripod midway between 2 vertical surfaces about 100' apart.

English

• Mount your Rotary Laser on a tripod so it is aimed front-to-back toward the vertical surfaces. (next page)

• Level the Laser, following the procedure in the “Horizontal Leveling” section of this manual.

• Quick Check:

1. Compare the position of the bubbles in the front and rear vials

(Fig. AA).

2. If the two bubbles are not in about the same position in their

vials, (both about centered) have your Rotary Laser calibrated at a D

EWALT service center.

• Turn the unit on so that the lasers are on and rotating.

• Go to surface #1 and mark the center of the beam. If it is difficult to see the beam, use your Laser Enhancement Glasses, Target Card or optional DW0732 Digital Laser Detector.

• Go to surface #2 and mark the center of the beam.

• Loosen the screw holding the Laser to the tripod, but do not remove the Laser.

• Rotate the Laser 180˚ (Fig. BB)

• Level the Laser again, following the procedure in the “Horizontal Leveling” section of this manual.

• Turn the unit on if it is not already on, so the lasers are on and rotating.

• Go to surface #1 and mark the center of the beam.

• Go to surface #2 and mark the center of the beam.

• Measure the difference between the marks on surface #1.

• Measure the difference between the marks on surface #2.

• The difference between the marks on surface #1 must equal the difference between the marks on surface #2. If these are not equal, there was user set up or marking error.

• If the difference between the marks on surface #1 is 1/4" or less, the Laser is properly calibrated.

• If the difference between the marks on surface #1 is more than 1/4", have your Rotary Laser calibrated at a D

EWALT service

center.

HORIZONTAL CHECKING FOR SIDE-TO-SIDE TILT ERROR

• Set up tripod midway between 2 vertical surfaces 100' from each other.

• Mount your Rotary Laser on a tripod so that it is aimed side-to-side toward the vertical surfaces.

• Level the Laser, following the procedure in the “Horizontal Leveling” section of this manual.

• Turn the unit on so that the lasers are on and rotating.

• Go to surface #1 and mark the center of the beam. If is difficult to see the beam use one of the aids mentioned earlier.

• Go to surface #2 and mark the center of the beam.

• Loosen the screw holding the Laser to the tripod but do not remove the Laser.

• Rotate the Laser 180˚.

• Level the Laser again, following the procedure in the “Horizontal Leveling” section.

• Turn the unit on if not already on, so that the lasers are on and rotating.

• Go to surface #1 and mark the center of the beam.

• Go to surface #2 and mark the center of the beam.

• The difference between the marks on surface #1 must equal the difference between the marks on surface #2. If these are not equal, there was user set up or marking error.

• If the difference between the marks on surface #1 is 1/4" or less, the Laser is properly calibrated.

• If the difference between the marks on surface #1 is more than 1/4", have your Rotary Laser calibrated at a D

EWALT service

center.

CONE ERROR CHECK

• Your D

EWALT Rotary Laser contains 2 laser diode assemblies. It

is highly unlikely that both lasers would have shifted by identical amounts. The easiest way to test for possible “cone error” is to compare the two laser beams.

• Level the laser, following instructions in the “Horizontal Leveling” section of this manual.

• Quick Check:

1. Turn the unit on so that the lasers are on and rotating.

2. You should see a single red line on a vertical surface. If you see

a double line, have your Rotary Laser calibrated by a DEWALT service center.

• Turn unit on so that the lasers are on but NOT rotating.

• Using the Manual Rotation Button, rotate the head so that the lasers appear as two dots on a vertical surface about 25 feet away.

• Compare the vertical position of the center of each laser beam. The centers should be within 3/32"(vertically) of each other.

• If the centers of the two beams differ by more than 3/32" (vertically), then have your Rotary Laser calibrated at a D

EWALT ser-

vice center.

PLUMB ERROR CHECK

• Set up a tripod about 25 feet from a vertical surface.

• Mount your Rotary Laser on the tripod.

• Following the procedure in the “Two Position Pivoting Head” section of this manual, set the Rotary Laser head in the plumb position.

• Hang a plumb bob from the vertical surface.

• Level the laser, following instructions in the “Vertical Plumbing” section of this manual.

• Turn the unit on so that the lasers are on and rotating.

• Rotate the laser on the tripod so that the beam is in the line with the plumb bob.

• Ensure that the laser is still level.

• If the beam lies along the same line as the plumb bob string, then the calibration is acceptable.

• If the beam does not lie along the same line as the plumb bob string, have your Rotary Laser calibrated at a D

EWALT service

center.

THE BATTERY WILL NOT LOCK IN PLACE

See “Installing the Battery Pack”

THE LASER WILL NOT TURN ON

Ensure that a fully charged battery is properly inserted into the tool.

TIP:

See “Installing the Battery Pack” section. Rotate the ON/OFF

VARIABLE SPEED Knob clockwise to turn the power on.

TIP:

See “Control Panel” section. If the laser still doesn't turn on, take the tool to a D

EWALT service center.

AFTER TURNING THE LASER ON, 2 LASER DOTS ARE PROJECTED FROM THE ROTARY HEAD

The DW073 Cordless Rotary Laser has been designed with dual, side by side laser diodes. Two diodes allows the laser to avoid blind spots which could potentially be created by the protective cap over the rotary head and also produce an extremely bright beam when the rotary laser head is spun.

THE LASER IS PROJECTING 2 LASER LINES WHEN THE LASER HEAD IS ROTATED

Take the laser to a DEWALT service center for calibration.

THE POWER LED LIGHT IS FLASHING, THE ROTARY HEAD HAS STOPPED SPINNING AND THE LASER DIODES HAVE SHUT DOWN.

This indicates that the battery pack needs to be recharged.

TIP:

See

“Removing the Battery Pack” and “Charging Procedures.”

THE BUMP SENSOR WARNING LED LIGHT IS FLASHING

See “Bump Sensor” section for operating instructions.

THE BUMP SENSOR WILL NOT TURN THE LASER OFF AFTER THE TOOL HAS GONE OUT OF LEVEL

The Bump Sensor is NOT AN OUT OF LEVEL SENSOR. See “Bump Sensor” section.

THE ROTATING LASER BEAM IS DIFFICULT TO SEE INDOORS

Ambient light conditions will influence the visibility of the laser beam. To aid in beam visibility, adjust the rotation speed using the ON/OFF VARIABLE SPEED SWITCH. Remember: Slow Speed = Bright Beam; Fast Speed = Solid Beam. Wearing the Laser Enhancement Glasses can also help you see the beam better.

I NEED TO ADJUST THE LASER FOR A VERTICAL / PLUMB ORIENTATION

See “Two-Position Pivoting Head” section.

I NEED TO ADJUST THE LASER FOR MOUNTING ON A WALL

See “Wall Mount” section.

THE LASER ROCKS WHEN POSITIONED ON THE FLOOR

The laser is designed to sit on 3 contact points for maximum stability. Two of these contact points are stationary while the third is adjustable. To roughly position the tool on the floor adjust the Base Leveling Knob, which is located under the battery pack.

I NEED TO STOP THE ROTARY HEAD ROTATION TO DIRECT THE LASER DOT ONTO A MARK OR TO SET A MARK

See “Manual Head Rotation” section.

THE BUBBLE(S) IN THE VIAL(S) WILL NOT MOVE WHEN ATTEMPTING TO LEVEL THE LASER

The tool must be positioned on a relatively smooth and level surface before being leveled. The laser cannot be leveled if the tool is set up outside of its leveling range.

TIP:

Use the Base Leveling Knob to roughly level the tool before attempting to level the laser with the leveling knobs.

TIP:

Make sure that the Two-Position Pivoting Head is locked into either the plumb or level setting before attempting to level the laser. See “Two-Position Pivoting Head” section.

I CAN ONLY ADJUST THE BUBBLE IN THE PLUMB VIAL WHEN ATTEMPTING TO PROJECT A VERTICAL LASER LINE

See “Vertical Plumbing” section for instructions on projecting a vertical laser line.

COLD STORAGE INFORMATION
