Charging a Battery (Fig. B)

Plug the charger into an appropriate outlet before inserting battery pack.
Insert the battery pack 1 into the charger, making sure the battery pack is fully seated in the charger. The red (charging) light will blink repeatedly indicating that the charging process has started.
The completion of charge will be indicated by the red light remaining ON continuously. The battery pack is fully charged and may be used at this time or left in the charger. To remove the battery pack from the charger, push the battery release button 2 on the battery pack.
NOTE: To ensure maximum performance and life of lithium-ion battery packs, charge the battery pack fully before first use.
Charger Operation
Refer to the indicators below for the charge status of the battery pack.

Charge Indicators

| Charging|
---|---|---
| Fully Charged|
| Hot/Cold Pack Delay*|

The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure. The compatible charger(s) will not charge a faulty battery pack. The charger will indicate faulty battery by refusing to light.
NOTE: This could also mean a problem with a charger.
If the charger indicates a problem, take the charger and battery pack to be tested at an authorised service centre.
Hot/Cold Pack Delay
When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life. A cold battery pack will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms.The DCB118 charger is equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled. Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of the charger.
Electronic Protection system
XR Li-Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge.
The tool will automatically turn off if the Electronic Protection System engages. If this occurs, place the lithium-ion battery pack on the charger until it is fully charged.
Wall Mounting
These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 25.4 mm long with a screw head diameter of 7–9 mm, screwed into wood to an optimal depth leaving approximately 5.5 mm of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.
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.

OPERATION

Instructions for Use
WARNING: Always observe the safety instructions and applicable regulations.
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

OPERATING TIPS

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 Checking Laser Accuracy.
Before attempting to use the laser, make sure it is positioned securely, on a smooth, flat stable surface that is level in both directions.
To increase beam visibility, use a Laser Target Card (Figure N)
CAUTION: To reduce the risk of serious injury, never stare directly into the laser beam with or without these glasses.
Refer to Accessories for important information.
Always mark the center of the beam created by the laser.
Extreme temperature changes can cause movement or shifting of building structures, metal tripods, equipment, etc., which can effect accuracy. Check your accuracy often while working.
If the laser has been dropped, check to make sure your laser is still calibrated. Refer to Checking Laser Accuracy.

Turning the Laser On (Fig. D)
With the laser off, place it on a flat surface. This model has a pendulum locking switch 5 and a keypad to activate the laser beams with two ON/OFF buttons; one for a horizontal laser line and one for a vertical laser line . Each laser line is powered on by moving the pendulum lock switch to the UNLOCKED/ ON position and pressing the required ON/OFF button on the keypad. The laser lines can be powered one at a time or at the same time. Pressing the ON/OFF buttons again turns the laser
lines off. The pendulum locking switch disables the lasers as well as locking the pendulum, and should always be placed in the LOCKED/OFF position when the laser is not in use.

Checking Laser Accuracy

The laser tools are sealed and calibrated at the factory. It is recommended that you perform an accuracy check prior to using the laser for the first time (in case the laser was
exposed to extreme temperatures) and then regularly to ensure the accuracy of your work. When performing any of the accuracy checks listed in this manual, follow these guidelines:

Use the largest area/distance possible, closest to the operating distance. The greater the area/distance, the easier to measure the accuracy of the laser.
Place the laser on a smooth, flat, stable surface that is level in both directions.
Mark the center of the laser beam.

Field Calibration Check
Checking Accuracy – Horizontal Beam, Scan
Direction (Fig. E)
Checking the horizontal scan calibration of the laser requires two walls at least 30′ (9 m) apart. It is important to conduct a calibration check using a distance no shorter than the distance of the applications for which the tool will be used.

Attach the laser to a wall using its pivot bracket. Make sure the laser is facing straight ahead.
Turn on the laser’s horizontal beam and pivot the laser approximately 45˚ so that the right-most end of the laser line is striking the opposing wall at a distance of at least 30′ (9 m). Mark the center of the beam (a).
Pivot the laser approximately 90˚ to bring the left-most end of the laser line around to the mark made in Step 2. Mark the center of the beam (b).
Measure the vertical distance between the marks.
• If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center.

Distance Between Walls| Allowable Distance Between a and b
---|---
10.0 m| 3.0 mm
12.0 m| 3.6 mm
15.0 m| 4.5 mm

Checking Accuracy – Horizontal Beam, Pitch Direction (Fig. F)
Checking the horizontal pitch calibration of the laser requires a single wall at least 30′ (9 m) long. It is important to conduct a calibration check using a distance no shorter than the distance of the applications for which the tool will be used.

Attach the laser to one end of a wall using its pivot bracket.
Turn on the laser’s horizontal beam and pivot the laser toward the opposite end of the wall and approximately parallel to the adjacent wall.
Mark the center of the beam at two locations (a, b) at least 30′ (9m) apart.
Reposition the laser to the opposite end of the wall.
Turn on the laser’s horizontal beam and pivot the laser back toward the first end of the wall and approximately parallel to the adjacent wall.
Adjust the height of the laser so that the center of the beam is aligned with the nearest mark (b).
Mark the center of the beam (c) directly above or below the farthest mark (a).
Measure the distance between these two marks (a, c).
• If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center. Distance Between Walls| Allowable Distance Between a and c
---|---
10.0 m| 6.0 mm
12.0| 7.2 mm
15.0| 9.0 mm

Checking Accuracy – Vertical Beam (Fig. G)
Checking the vertical (plumb) calibration of the laser can be most accurately done when there is a substantial amount of vertical height available, ideally 20′ (6 m), with one person on the floor positioning the laser and another person near a ceiling to mark the position of the beam. It is important to conduct a calibration check using a distance no shorter than the distance of the applications for which the tool will be used.

Start by marking a 5′ (1.5 m) line on the floor.
Turn on the laser’s vertical beam and position the unit at one end of the line, facing the line.
Adjust the unit so its beam is aligned and centered on the line on the floor.
Mark the position of the laser beam on the ceiling (a). Mark the center of the laser beam directly over the midpoint of the line on the floor.
Reposition the laser at the other end of the line on the floor. Adjust the unit once again so its beam is aligned and centered on the line on the floor.
Mark the position of the laser beam on the ceiling (b), directly beside the first mark (a).
Measure the distance between these two marks.
• If the measurement is greater than the values shown below, the laser must be serviced at an authorized service center. Distance Between Walls| Allowable Distance Between a and b
---|---
2.5 m| 3.4 mm
3.0 m| 4.2 mm
4.0 m| 5.5 mm
6.0 m| 8.2 mm

Using the Laser
Leveling the Laser

As long as the laser is properly calibrated, the laser is self-leveling. Each laser is calibrated at the factory to find level as long as it is positioned on a flat surface within average ± 4 ° of level. No manual adjustments are required. If the laser has been tilted so much that it cannot self-level (> 4 °), the laser beam will flash. There are two flashing sequences associated with the out of level condition.

Between 4 ° and 10 ° the beams flash with a constant blink cycle
At angles greater than 10 ° the beams flash with a three blink cycle.

When the beams flash THE LASER IS NOT LEVEL (OR PLUMB) AND SHOULD NOT BE USED FOR DETERMINING OR MARKING LEVEL OR PLUMB. Try repositioning the laser on a more level surface.

Using the Pivot Bracket (Fig. H, I)
The laser has a magnetic pivot bracket 6 permanently attached to the unit.
WARNING: Position the laser and/or wall mount on a stable surface. Serious personal injury or damage to the laser may result if the laser falls.

The bracket has a keyhole slot 7 so it can be hung from a nail or screw on any kind of surface.
The bracket has magnets 10 which allow the unit to be mounted to most upright surfaces made of steel or iron.

Common examples of suitable surfaces include steel framing studs, steel door frames, and structural steel beamsBefore attaching the pivot bracket against a stud 11 , plac the Metal Enhancement Plate 12 on the opposite side of the stud.

MAINTENANCE

Your power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect before making any adjustments or removing/installing attachments or accessories. An accidental start-up cancause injury.

To maintain the accuracy of your work, check the laser often to make sure it is properly calibrated. See Field Calibration Check.
Calibration checks and other maintenance repairs may be performed by DEWALT service centres.
Do not store your laser in the kit box if the laser is wet. The laser should be dried first with a soft dry cloth prior to storage.

Cleaning
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 tool; never immerse any part of the tool into a liquid. Exterior plastic parts may be cleaned with a damp cloth. Although these parts are solvent resistant, NEVER use solvents. Use a soft, dry cloth to remove moisture from the tool before storage.

TROUBLESHOOTING

The Laser Does Not Turn On

Fully-charge the battery pack and then reinstall it in the laser unit.
If the laser unit is exposed to extremely hot temperatures, the unit will not turn on. If the laser has been stored in extremely hot temperatures, allow it to cool. The laser level will not be damaged by pressing the on/off button before cooling to its proper operating temperature.

The Laser Beams Flash
The lasers are designed to self-level up to an average of 4 ° in all directions If the laser is tilted so much that the internal mechanism cannot level itself, the laser beams will flash indicating that the tilt range has been exceeded. THE FLASHING BEAMS CREATED BY THE LASER ARE NOT LEVEL OR PLUMB AND SHOULD NOT BE USED FOR DETERMINING OR MARKING LEVEL OR PLUMB. Try repositioning the laser on a more level surface. If the laser battery pack has a low state of charge, the beams will flash in a distinctive pattern of 3 quick flashes in 1 second, followed by constant light output for 4 seconds. This flashing pattern indicates that the battery pack should be replaced with a fully charged battery pack.
The Laser Beams Will Not Stop Moving
The laser is a precision instrument. Therefore, if it is not positioned on a stable (and motionless) surface, the laser will continue to try to find level. If the beam will not stop moving, try placing the laser on a more stable surface. Also, try to make sure that the surface is relatively flat, so that the laser is stable.
Accessories (Fig. K–M)
Some laser kits are packaged with a drop ceiling bracket 13 . The drop ceiling bracket contains a steel plate and attaches to the magnetized pivot bracket 6 (Fig. K). The drop ceiling bracket is equipped with both 1/4 – 20 and 5/8 – 11 female threads on the bottom of the unit). This thread is to accommodate current or future DEWALT accessories. Figures L and M show examples of accessories that are sold separately from these lasers. Only use DEWALT accessories specified for use with this product. Follow the directions included with the accessory.
WARNING: Since accessories, other than those offered by DEWALT, have not been tested with this product, use of such accessories with this tool could be hazardous. To reduce the risk of injury, only DEWALT recommended accessories should be used with this product. If you need any assistance in locating any accessory, please contact your nearest DEWALT service center or go to www.DEWALT.com.
Target Card (Fig. N)
Some laser kits include 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 standard and metric scales. The laser beam passes through the green plastic and reflects off of the reflective tape on the reverse side. The magnet at the top of the card is designed to hold the target card to ceiling track or steel studs to determine plumb and level positions. For best performance when using the Target Card, the DEWALT logo should be facing you.
