This document describes the Johnson Electronic Horizontal & Vertical Self-Leveling Rotary Laser Level, available in models 40-6526, 40-6529, and 40-6544. This is a Class IIIa laser tool designed for laying out indoor or outdoor construction projects, emitting one rotating laser beam and one plumb beam. It complies with CFR 21, parts 1040.10 and 1040.11, as well as international safety rule IEC 285.
The laser level features a large electronic self-leveling range of ±5°. If the unit is inclined beyond this range, the laser line flashes, rotation stops, and an audible alarm activates. It supports both vertical and horizontal working modes with electronic self-leveling, providing a rotating laser beam and a 90° split beam. The tool offers two rotational speeds: 200 and 500 rpm. A scan function allows adjustment of the scan line size and direction. An out-of-level alarm ensures working accuracy. The device also includes a fine self-calibration function. In "Tilt Mode," the laser stops rotating and flashes if bumped, ensuring work accuracy. A slope function enables users to perform slopes in both X and Y axes. The unit is designed to be dust and rain resistant.
The laser level can be powered on by pressing the power button, after which it automatically levels itself and begins rotation. Pressing the power button again turns it off. A red power button on the remote powers down the laser beam and rotating beacon, but does not turn off the laser itself. A blinking battery indicator lamp signals low battery, requiring replacement or charging of the Ni-MH pack. If the laser is beyond its ±5° auto-leveling range, an audible alarm sounds, rotation stops, and the beam flashes, requiring repositioning.
The "Height of Instrument (H.I.)" feature allows the laser to enter TILT mode, indicated by a lit indicator light. If the leveled laser is moved or bumped in TILT mode, rotation stops, and the TILT indicator and laser beam flash. Pressing the vial button on the laser or remote relevels the laser, keeping it in TILT mode. Pressing the TILT button again exits this mode.
Speed adjustment allows switching between 500rpm and 200rpm rotation speeds using the speed adjustment button. This function is inactive during self-leveling.
Scan mode is activated by pressing the scan mode button. Subsequent presses cycle through a shorter bright laser line and a bright laser point. To return to rotating, press the speed adjustment button. The scan line can be rotated clockwise or counter-clockwise using dedicated buttons.
Slope mode is entered by pressing the slope mode button once for X-direction slope. This activates dual-axis slope mode and turns off self-leveling motors. Left and right buttons adjust the slope angle. A second press selects Y-direction slope, with similar adjustment. A third press returns to X-direction slope. Pressing and holding the button returns to normal operation. Holding the slope mode button for three seconds enters single slope mode (X-axis default), with the X-axis LED on and Y-axis LED flashing. The laser self-levels in this mode.
A Timed Auto-off Function puts the unit into sleep mode after pressing the remote control's power button once, powering down the beacon and laser beam. If in sleep mode for 30 minutes, the unit automatically turns off. A second press of the remote's power button exits sleep mode and enters self-level mode.
The Remote Control Shield Key, when pressed, turns off the remote control LED, preventing the laser from receiving remote control information.
For vertical mode, the laser should be placed on a flat surface with the keypad facing up.
The 40-6715 laser detector (for model 40-6529 only) is an accessory for detecting laser signals in rotary laser levels, providing horizontal and vertical references quickly and precisely. It features high sensitivity, a double-faced display, low power consumption, good reliability, and ease of use. The detector has fine (±0.039" / ±1mm) and coarse (±0.098" / ±2.5mm or ±0.394" / ±10mm) accuracy settings, an automatic shut-off after 6 minutes without a signal, and runs on a 9V battery for 30 hours. It provides slow short beeps, rapid short beeps, and continuous sound, with a down arrow, up arrow, and horizontal on-grade bar LED display.
The instrument requires self-check and fine calibration before each use. The user is responsible for verifying calibration. For X & Y-Direction Accuracy Self-Check, the unit is placed 50' from a wall, and the laser beam is marked at points A and B (after 180° rotation) for X-direction, and points C and D (after 90° rotation) for Y-direction. If the vertical distance between A and B, or C and D, is more than 1/32" at 50', the unit is out of calibration.
Fine calibration using the remote control is valid for errors less than 1/2" over 100ft. Larger errors require a qualified technician. Calibration mode is accessed by simultaneously pressing the Power and TILT buttons. The X & Y LEDs blink three times. The remote control's lower cover reveals an operation panel for calibration. The X/Y button toggles control between X, Y, and Z axes. UP and DOWN arrows adjust the laser height. The ENTER button accepts the calibration value. After calibration, the unit must be powered off and on again to activate the settings.
For detector maintenance, the unit, especially the reception window, should be kept clean with a soft, dry cloth.
This is a precision tool requiring careful handling. Avoid shock vibrations and extreme temperatures. Turn off the unit before moving or transporting. Remove batteries for extended storage (over three months) to prevent damage. Always store the unit in its case when not in use. Avoid getting the unit wet. Keep the laser output window dry and clean; use a soft, dry cloth. Do not use harsh chemicals, strong detergents, or cleaning solvents.
Johnson Level & Tool offers a three-year limited warranty. Warranty registration is required within 30 days of purchase. Use of non-Johnson® parts and accessories voids the warranty. Non-warranty repairs and calibration must be done by an authorized service center.
