Alkaline Battery Installation: Put 3 “D” alkaline batteries (not included) into the battery pack according to the polarity direction, then insert the battery pack into the laser. (Note: Batteries facing up.) Rechargeable Battery Pack Installation: Install the rechargeable battery pack into the laser.
6274H-1_Manuals 9/26/12 10:44 AM Page 8 Note: (1) Charge the rechargeable battery when the battery power is low (battery symbol on the LCD is flashing). This will extend the battery life. (2) If the laser is not going to be used for a long period of time, charge the rechargeable battery every 2-3 months.

6274H-1_Manuals 9/26/12 10:44 AM Page 10 Power On/Off Button: Press this button to power on/off the laser. The laser is in self-leveling status when powered on. Default rotate speed is 600 RPM Default grade for X-axis and Y-axis is 0. The remote channel will display CH1. If there is a matched remote control which is on, the remote status will display . If there is not a matched remote, it will display . When powered on, the laser will automatically check the battery capacity.
6274H-1_Manuals 9/26/12 10:44 AM Page 11 setting mode, the Y-axis symbol “Y” and axis direction symbol (+) will flash. The setting method is the same as the X-axis. After the Y-axis grade setting is completed, press the key for two seconds to confirm the grade setting. The laser will beep once and will quit the grade setting mode and start to work under the confirmed grade.
6274H-1_Manuals 9/26/12 10:44 AM Page 12 TILT Button: When turning on the laser, the laser will self-level and begin to rotate. The TILT symbol on the LCD will blink for thirty seconds after the laser begins to rotate. During these thirty seconds if the laser is moved the laser will stop rotating , re-level and begin to rotate again. After thirty seconds the TILT symbol will stop blinking and will become solid. If the laser is moved when the TILT symbol is solid, the laser will stop rotating.
6274H-1_Manuals 9/26/12 10:44 AM Page 13 Level Button/LCD Backlight Button: Push this button once to start self-leveling after the laser has been moved in TILT mode. Hold this button in for three seconds to turn on the LCD backlight. Remote Channel Button: Push this button to switch the remote channel from CH1 to CHF. Vertical Applications: Place the laser on its side using the vertical bracket. Center the circular bubble vial with the use of the leveling knobs.
6274H-1_Manuals 9/26/12 10:44 AM Page 14 Battery Status Indicator: When powered on, the laser will automatically check the battery capacity and show the following status: Full battery Half battery Low battery Very low battery and laser should be charged Empty battery and laser needs to be charged Using the Remote Control: 1. Install two “AA” batteries in the battery compartment following the diagram inside the compartment. 2. With the laser turned on, turn on the remote by pressing the power button. 3.
6274H-1_Manuals 9/26/12 10:44 AM Page 15 4. The laser and remote default into channel (CH1) 1. The remote control will only work when the laser and remote are on the same channel. If other lasers are in the area, the remote and laser can be changed from CH1 to CH9 and CHA to CHF making it so the remote will only work for a specific laser. To change the remote channel, press the remote button. 5.
6274H-1_Manuals 9/26/12 10:44 AM Page 16 Detector Usage Two-Sided Laser Detector with Clamp Model No. 40-6715 The 40-6715 laser detector is an indispensable accessory when using rotary laser levels. The main function of the detector is to detect the position of the laser signals that are transmitted by rotary lasers. This detection quickly and precisely provides the user with the horizontal reference.

6274H-1_Manuals 9/26/12 10:44 AM Page 22 8. Self-Check & Fine Calibration IMPORTANT: It is the responsibility of the user to verify the calibration of the instrument before each use. The instrument must be self-checked for accuracy periodically, h specifically before a large project, where accuracy is critical. If the accuracy is found to be beyond tolerance, some adjustment may be made as follows. X-Axis and Y-Axis Accuracy Check: 1. Place a table indoors, approximately 20m from a wall.
6274H-1_Manuals 9/26/12 10:44 AM Page 23 3. Rotate the instrument 90°, and after self-level completes, mark a line and label as ‘B’. Repeat two more times, labeling lines as ‘C’, and ‘D’. 4. Measure the vertical distance ‘h’ between the highest and the lowest points among A, B, C, and D. 5. If h=2mm or less, accuracy is qualified. If h>2mm but <10mm, adjust the calibration. If h>10mm, please contact an authorized service center or dealer for repair. Z-Axis Accuracy Check: 1.
6274H-1_Manuals 9/26/12 10:44 AM Page 24 Accuracy Calibration of the X and Y-Axis: 1. Power off the instrument and face the X-axis to the wall. 2. Press and simultaneously, and then release while still pressing for approximately ten seconds. The instrument will then enter Calibration mode, and ‘CAL’ will be displayed. 3. Using the remote control, press the button to select the axis to be calibrated. 4.
