. Operating Instructions IMPORTANT: It is the responsibility of the user to verify the calibration of the instrument before each use. Battery Installation Note: Always check to be sure that the on/off switch is in the off position before removing and replacing batteries. Ni-MH Rechargeable Battery Pack Installation 1. Unscrew the battery cover bolt and remove the battery cover. 2.
Note: (1) For the first two charges of new rechargeable batteries, it is necessary to charge for 12 plus hours. (2) The unit can still work during charging with the adapter. (3) Do not charge alkaline batteries to avoid explosion. (4) Used (discharged) batteries are hazardous waste and should be disposed of properly. Instrument Usage 1. Put in Ni-MH rechargeable battery pack, or 4 “C” alkaline batteries (not included), or connect with the 6V DC power through the power jack. 2.
7. Using the Product Operating Panel Instrument Panel Remote Control Panel Power On/Off 1. Press the power button to power on. The power indicator lamp will light up and then the instrument will automatically level itself, with rotation occurring once the unit is level. 2. Press the power button again to power off. Low Battery Indication If the battery indicator lamp is lit, this means low battery voltage. To ensure normal operation, replace batteries or charge the rechargeable Ni-MH battery pack.
Height of Instrument (H.I.) - TILT 1. After powering on the instrument and entering into auto-level status, press the tilt button. When the indicator is on (see figure), the instrument enters into TILT mode. If the leveled instrument is moved or bumped, the head will stop rotation and the TILT indicator light and laser beam will flash instead of the unit performing the auto-level function. Press the tilt button on the panel or remote to quit the tilt mode and enter into auto-level status. 2.
Adjust the inclination extent of the slope Pressing the up/down arrow keys on the remote control, will adjust the inclination of the instrument slope. A single press will cause a slight adjustment and a continuous presses will cause a quick adjustment. If laser is taken past its slope range (±8º), the laser will deliver an audible alarm and the laser beam will flash and stop rotating. Sleep Mode 1. The first press of the POWER button on the remote control (fig.4) will make the instrument enter sleep mode.
Detector Usage 1. Product Description A laser detector is an indispensable accessory when using this rotary laser level. The main function of the detector is to locate the position of laser signals transmitted by rotary lasers. This detection quickly and precisely provides the user with the horizontal reference. This product features a high level of sensitivity, a double-faced display, low power consumption, reliability and easy use. 2.
8. Self-Check and 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 before operation. If the accuracy is found beyond tolerance, user can make some adjustment according to directions as follows. X-Direction Accuracy Self-Check 1. For clarity, we define the direction of handle as Y-direction, and another direction as X-direction 2.
X-direction self-check with the same method as Y-direction self-check, and mark point C and point D by turns. 7. If point C and point D are within 1/32” at 50’, the accuracy is within tolerance. Otherwise reference section 12 of this document. Enter self-calibration In power off status, press the power and the tilt buttons of the laser unit simultaneously. Then let go of the power button while still pressing the tilt button.
Adjust laser beam to reference position Press the up/down arrow buttons on the remote control to adjust the laser beam to reference position. Confirm calibration value Press ‘ENT’ button on the remote control to confirm self-calibration value. The X direction self-calibration indicator light will extinguish after pressing this button.
Confirm calibration value Press ‘ENT’ button on the remote control to confirm self-calibration value. The Y direction self-calibration indicator light will extinguish after pressing this button. Note: In order to make the calibration effective, you must power off the instrument after the calibration, and then power it on again. Y-axis accuracy check is a necessity after X-axis calibration, and X-axis accuracy check is also a necessity after Y-axis calibration.
