Using rechargeable NiMH batteries

If your laser has a rechargeable battery, you must charge it for 8 hours before first using the laser.

XInsert the charger plug into the jack located at the back of the laser, under the wall mount.

XPlug the charger into an electrical outlet.

XCharge for 8 hours.

Later recharging

The laser can be charged while working if electricity is available on the jobsite. Simply plug in the charger and keep on working.

You can also remove the battery pack to charge it, or replace it with the alkaline battery compartment to keep on working.

Notes and Responsibilities

•It is the responsibility of the user to follow operating instructions and to periodically check the accuracy of the instrument and work as it progresses.

•The laser is adjusted to the defined accuracy specifi- cations at the factory. It is recommended to check

your laser for accuracy upon receipt and periodically thereafter to ensure accuracy is maintained. If your laser requires adjustment, contact the nearest autho- rized service center or adjust the laser using the following procedure.

•Do not enter this mode or attempt adjustment unless you plan to change the accuracy. Accuracy adjust- ment should only be performed by a qualified indi- vidual that understands basic adjustment principles.

Checking level accuracy

To check the level accuracy of your laser, place the unit on a flat, level surface or tripod approximately 30 meters (100 ft.) from a wall. See illustration {L} in the back, inside cover of this manual.

XAlign the X-axis so that it is square to the wall. Allow the laser to self-level completely (approximately one minute after the laser begins to rotate). Then mark the position of the beam (Position 1).

XRotate the laser 180°, allow it to self level and mark the opposite side of the first axis (Position 2).

XAlign the Y-axis by rotating the laser 90° so that this axis is now square to the wall. Allow the laser to self- level completely, and then mark the position of the beam (Position 3). See illustration {M} in the back, inside cover of this manual.

XRotate the laser 180°, allow it to self level and mark the opposite side of the Y-axis (Position 4).

XThe laser is within its accuracy specification if the four marks are within ± 3 mm (± 1/8") from the center.
