ASSEMBLY AND ADJUSTMENT

WARNING: Do not place the laser in a position

which may cause anyone to intentionally or unintentionally stare into laser beam. Serious eye injury may result from staring at the beam. Setting Up the Laser The laser facilitates various set-ups, making it useful for severalapplications. Manual Head Rotation The laser is designed with a protective alloy cage around the rotary head to prevent accidental damage from work site activities. You can still direct the beam to establish or transfer a mark by pressing the scan mode once and jogging the dot using the Clockwise/counter clockwise buttons.30 ENGLISH Wall Set-up (Fig. C, M) The wall mount is used for mounting the laser to a wall track to aid in drop ceiling installation and other specialty levellingprojects.

CAUTION: Before attaching the laser level to wall track or ceiling angle, be sure that the track or angle is properlysecured.

1. Place the laser on the mounting base

aligning the 5/8-11 screw hole on the tripod adapter (

, Fig. C) attached to the bottom of the laser with the hole

in the mounting base. Turn the mounting knob

to secure the laser.

2. With the wall mount measuring scale

facing you, loosen the wall mount clamp locking knob

to open the clampjaws.

3. Position the clamp jaws around the wall track or ceiling

angle and tighten the wall mount clamp locking knob

to close the clamp jaws onto the track. Be sure that the wall mount clamp locking knob is securely tightened beforeproceeding.

CAUTION: Always use a ceiling wire hanger or equivalent material, in addition to the wall mount clamp locking knob, to help secure the laser level while mounting it to a wall. Thread the wire through the handle of the laser level. DO NOT thread the wire through the protective metal cage. Additionally, screws may be used to fasten the wall mount directly to the wall as a back-up. Screw holes

are located at the top of the wall mount.

, approximate a level position from the wall.

5. The laser can be adjusted up and down to the desired offset

height for working. To change the height, loosen the locking knob

located on the left of the wall mount.

6. Turn the adjustment knob

, located to the right of the wall mount, to move the laser level up and down to set your height. Use the wall mount measuring scale

to pinpoint your mark. NOTE: It may be helpful to turn the power on and turn the rotary head so that it puts a dot on one of the laser scales. The DeWALT target card is marked at 38mm, therefore, it may be easiest to set the offset of the laser to 38mm below thetrack.

7. Once you have positioned the laser at the desired height,

to maintain this position. Tripod Set-up (Fig. C)

1. Position the tripod securely and set it to the desired height.

2. Make sure that the top of the tripod is roughly level. The

laser will self-level only if the top of the tripod is within ± 5˚ of level. If the laser is set up too far out of level, it will beep when it reaches the limit of its leveling range. No damage will be done to the laser, but it will not operate in an “out of level” condition.

3. Secure the laser to the tripod by attaching the tripod

as shown in Figure C to the laser body. The adapter may be assembled to the bottom for level mode

or to the side for plumb mode

. Place the assembly on the tripod and screw the threaded knob on the tripod into the female thread on the tripod adapter. NOTE: Be sure that the tripod you are working with has a 5/8"–11 threaded screw to ensure secure mounting.

4. Turn the laser on and adjust the rotation speed and controls

as desired. Floor set-up (Fig. D) The laser level can be positioned directly on the floor for leveling and plumbing applications such as framing walls.

1. Place the laser on a relatively smooth and level surface

where it will not be disturbed.

2. Position the laser for a level

3. Turn the laser on and adjust the rotation speed and controls

as desired. NOTE: The laser will be easier to set up for wall applications if the rotation speed is set to 0 rpms and if the remote control is used to line up the laser with control marks. The remote allows one person to set up the laser. OPERATION

WARNING! Do not place the laser in a position which may cause anyone to intentionally or unintentionally stare into the laser beam. Serious eye injury may result from staring at the beam. Instructions for Use

WARNING: Always observe the safety instructions and

applicable regulations.

• To extend battery life per charge, turn the laser off when it is not in use.

• To ensure the accuracy of your work, check the laser calibration often. Refer to Field Callibration Check under Laser Maintenance.

• Before attempting to use the laser, make sure the tool is positioned on a relatively smooth, secure surface.

• Always mark the centre of the laser line or dot. If you mark different parts of the beam at different times you will introduce error into your measurements.

• To increase working distance and accuracy, set up the laser in the middle of your working area.

• When attaching to a tripod or wall, mount the lasersecurely.

• When working indoors, a slow rotary head speed will produce a visibly brighter line; a faster rotary head speed will produce a visibly solid line.

• To increase beam visibility, wear Laser Enhancement Glass es and/or use a Laser Target Card to help find the beam.

• Extreme temperature changes can cause movement or shifting of building structures, metal tripods, equipment, etc., which can affect accuracy. Check your accuracy often while working.31 ENGLISH

• When working with the DeWALT Digital Laser Detector, set the laser’s rotation speed to the fastestsetting.

• If the laser is dropped or suffers a sharp blow, have the calibration system checked by a qualified service centre before using the laser. Laser Control Panel (Fig.B) The laser is primarily controlled by the power button

Digital Laser Detector: DW0743R (red beam) & DW0743G (green beam) (Fig.H,I) Some laser kits include a DeWALT Digital Laser Detector. The DeWALT Digital Laser Detector allows 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 but is compatible with most rotary red-beam (DW0743R) and green beam (DW0743G) lasers. It can be set to indicate the location of the beam to either the nearest 3mm or the nearest 1mm. The detector gives both visual signals through the display window

and audio signals through the speaker

to indicate the location of the laser beam. The DeWALT Digital Laser Detector can be used with or without the detector clamp. When used with the clamp, the detector can be positioned on a grade rod, leveling pole, stud or post. Batteries (Fig. H) The Digital Laser Detector is powered by a 9 volt battery. To install the battery provided, lift up on the battery compartment cover

. Place the 9 volt battery in the compartment, aligning the battery as shown . Detector Controls (Fig. I) The detector is controlled by the power button

and the accuracy mode button

When the power button is pushed once, the detector is turned on. The top of the display window shows the accuracy icon

. To decrease the volume of the audible signal that the detector emits when it senses a laser beam, push the button again; one of the half circles next to the horn icon will dissappear. To turn off the audible signal push the button a third time; the volume icon will dissapear. The DeWALT Digital Laser Detector also has an auto shut-off feature. If a rotary laser beam does not strike the beam detection window, or if no buttons are pressed, the detector will shut itself off in about 30minutes. When the detector is on, the top of the window shows an accuracy mode icon. Either the ±1mm accuracy mode icon

will appear, or the ±3mm accuracy mode icon

will appear. When the ±1mm accuracy mode icon appears, it indicates that the detector will give an “on grade” reading only when the laser beam is on grade or no more than 1mm above or below it. When the 3mm accuracy mode icon appears, it indicates that the detector will give an “on grade” reading when the laser beam is on grade or approximately 3mm above or below it. Push the accuracy mode button

once to change the accuracymode. Detector Operation (Fig. I)

1. Set up and position the rotary laser that you will be using

according to the manufacturer’s directions. Turn the laser on and make sure that the laser is rotating and emitting a laser beam. nOTE: This detector has been designed to be used only with a rotating laser. The detector will not work with a stationary beam laser level.

2. Turn the detector on by pressing the power/volume

3. Adjust the volume as desired as described in the

4. Position the detector so that the detector window

• The DeWALT Digital Laser Detector is waterproof. If you should drop the detector in mud, wet concrete, or a similar substance, simply hose the detector off. Do not use high pressure water, e.g., from a pressure washer.

• The best storage place is one that is cool and dry–away from direct sunlight and excess heat or cold. Detector Service Except for batteries, there are no user serviceable parts in the Digital Laser Detector. Do not disassemble the unit. Unauth- orized tampering with the laser detector will void allwarranties. Detector Troubleshooting The detector will not turn on.

• Press and release the power button.

• Check to see that the battery is in place and in the properposition.

• If the detector is very cold, allow it to warm up in a heatedarea.

• Replace the 9-volt battery. Turn the unit on.

• If the detector still does not turn on, take the detector to a DeWALT service center. The detector’s speaker makes no sound.

• Ensure that the detector is on.

• Press the volume button. It will toggle on and off.

• Ensure that the laser is turned on and that it is emitting a laser beam.

• If the detector is still not making any sound, take it to a DeWALT service center. The detector does not respond to the beam from another laser unit.

• The DeWALT Digital Laser Detector has been designed to work only with rotary lasers. The detector gives off a tone but the LCD display window does not function.

• If the detector is very cold, allow it to warm up in a heatedarea.

• If the LCD display window is still not functioning, take the detector to a DeWALT servicecenter. Construction Grade Rod (Fig. L)

DANGER: NEVER attempt to use a grade rod in a storm or

near overhanging electric wires. Death or serious personal injury will occur. Some laser kits include a grade rod. The DeWALT Grade Rod is marked with measurement scales on both sides and is constructed in telescoping sections. A spring-loaded button actuates a lock to hold the grade rod at various lengths. The front of the grade rod has the measurement scale starting at the bottom. Use this for measuring from the ground up when grading or leveling jobs. The back of the grade rod is designed to measure the height of ceilings, joists, etc. Fully extend the top section of the grade rod until the button locks into the previous section. Extend that section either until it locks into the adjacent section or until the grade rod touches the ceiling or joist. The height is read where the last extended section exits the previous lower section, as shown in FigureL. MAINTENANCE Your DeWALT laser unit has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper laser care and regular cleaning. Laser Maintenance

• Under some conditions, the glass lens may collect some dirt or debris. This will affect beam quality and operating range. The lens should be cleaned with a cotton swab moistened with water.

• The flexible rubber shield can be cleaned with a wet lint- free cloth such as a cotton cloth. USE WATER ONLY — DO NOT use cleansers or solvents. Allow the unit to air dry beforestoring.

• To maintain the accuracy of your work, check the calibration of the laser often. Refer to Field CalibrationCheck.

• Calibration checks and other maintenance repairs can be performed by DeWALT service centers. Two free calibration checks are included under the DeWALT One Year Free Service Con tract.

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

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

• Do not store your laser at temperatures below -18˚C or above 41˚C.

WARNING: Never use solvents or other harsh chemicals

for cleaning the non-metallic parts of the tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the unit; never immerse any part of the unit into a liquid. Never use compressed air to clean thelaser. Field Calibration Check (Fig.O, P) Field calibration checks should be done frequently. This section provides instructions for performing simple field calibration checks of your DeWALT Rotary Laser. Field calibration checks do not calibrate the laser. That is, these checks do not correct errors in the leveling or plumbing capability of the laser. Instead, the checks indicate whether or not the laser is providing a correct level and plumb line. These checks cannot take the place of professional calibration performed by a DeWALT service center. Level Calibration Check (X-axis)

1. Set up a tripod between two walls that are at least 15m

apart. The exact location of the tripod is not critical.

2. Mount the laser unit on the tripod so that the X-axis points

directly toward one of the walls.

3. Turn the laser unit on and allow it to self-level.35

4. Mark and measure points A and B on the walls as shown in

toward the opposite wall.

6. Allow the laser unit to self-level, and mark and measure

points AA and BB on the walls as shown in FigureP.

7. Calculate the total error using the equation:

Total Error = (AA – A) – (BB– B)

8. Compare total error to the allowable limits shown in the

following table. Distance between walls Allowable Error L = 15 m 3 mm L = 25 m 5 mm L = 50 m 10mm Level Calibration Check (Y-axis) Repeat the procedure above, but with the laser unit positioned so the Y-axis is pointed directly toward the walls. Plumb Error Check (Fig. Q)

1. Using a standard plumb bob as a reference, mark the top

and bottom of a wall. (Be sure to mark the wall and not the floor and ceiling.)

2. Position the rotary laser securely on the floor approximately

3. Turn the laser on, and point the dot at the mark on the

bottom of the wall. Then, using the up/down arrows on the remote control, rotate the dot upwards. If the center of the dot scans over the mark on the top of the wall, the laser is properly calibrated. NOTE: This check should be done with a wall no shorter than the tallest wall for which this laser will be used. Protecting the Environment Separate collection.
