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-2_Manuals 9/26/12 11:32 AM Page 7 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. (3) The instrument can operate while the batteries are recharging.

6274H-2_Manuals 9/26/12 11:32 AM Page 9 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 beam shield is off in all four quadrants; Default grade for X-axis and Y-axis is 0. The remote channel will display CH1. If there is a matched remote control with the power on, the remote status will display if there is not a matched remote, it will display .
6274H-2_Manuals 9/26/12 11:32 AM Page 10 completed, press the grade axis button for two seconds to enter into the Y-axis grade 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 this 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-2_Manuals 9/26/12 11:32 AM Page 11 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 become solid. If the laser is moved when the TILT symbol is solid, the laser will stop rotating.
6274H-2_Manuals 9/26/12 11:32 AM Page 12 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. Battery Status Indicator : When powered on, the laser will automatically check the battery capacity and show the following status.
6274H-2_Manuals 9/26/12 11:32 AM Page 13 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. The LCD on the remote will display the following 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.
6274H-2_Manuals 9/26/12 11:32 AM Page 14 Note: The battery symbol display on the remote shows the battery strength of the remote batteries and not the laser battery strength. The differences between the remote button and laser buttons are as follows: 1. Holding the on the remote Level/Backlight for three seconds will turn on the remote backlight. To turn off the backlight, hold the same button in again for another three seconds. 2. One press of the manual button will put the laser in “sleep” mode.
6274H-2_Manuals 9/26/12 11:32 AM Page 15 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.

The accuracy symbol displayed on the LCD will change. Volume Key Power on and press the volume key, the unit will cycle between a high sound, low sound and mute. The sound symbol displayed on the LCD will change accordingly. Note: There will be two beeps when turning the unit on and off.
6274H-2_Manuals 9/26/12 11:32 AM Page 19 When the laser signal is near the on-grade mark, the displayed up and down arrows will decrease as the distance to the on-grade mark decreases. Laser signal Laser signal Laser signal Laser signal 1. When detecting a horizontal laser signal, it is important to have the bubble vial centered, as the deflection of the receiver will influence its receiving accuracy. 2.

Self-Check & Fine Calibration IMPORTANT: It is the responsibility of the user to verify the calibration of the instrument before each use. h The instrument must be self-checked for accuracy periodically, 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-2_Manuals 9/26/12 11:32 AM Page 22 (Turning in a clockwise direction): A = X+ B = Y+ C = XD = Y3. 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.
6274H-2_Manuals 9/26/12 11:32 AM Page 23 Calibration Confirm: Press the button to confirm the calibration value after calibration is completed. Instrument will return to normal operation mode. Note: In the self-check and calibration mode, self-calibration coefficient is from 1600-2495. If user calibrates in this range, and accuracy is still not achievable, please contact an Authorized Service Center or Dealer for repair. • After Calibration is complete, user must turn the instrument off and then back on.
