Johnson Rotary Laser User Guide

Quick Start Guide: Models 40-6515, 40-6516, 40-6517 & 99-002K/006K/026K

Thank you for purchasing this Johnson rotary laser! This laser features simple operation in both horizontal (self-leveling) and vertical (manually leveling) planes and is ideal for job sites such as residential and small commercial grading and excavation job sites up to 800′ in diameter (up to 11 acres).
This tool features:

• Class IIIa laser
• 1/8″ @ 50′ accuracy
• Manual vertical mode
• 800′ range (diameter)
• Some models include a laser detector
• 99-026K includes a rechargeable NiMH battery

GETTING STARTED

1. Fully charge the NiMH battery or insert 4 fresh AA alkaline batteries into the laser.
2. Mount the laser on a tripod or other stable mounting surface in either the horizontal or vertical position.
3. For horizontal operation, unlock the pendulum and press The laser will self-level and rotate. If the laser is out of its self-leveling range, it will stop rotating and beep. NOTE: The laser will NOT operate in the horizontal position if the pendulum lock is engaged. To disengage it, rotate the knob counterclockwise.
4. For vertical operation, keep the pendulum in the locked position and adjust the manual leveling foot until the level vial indicates that the laser is level, then power on the laser by pressing .
5. Adjust your rotational speed by pressing . High speeds are recommended for use with a laser detector; low speeds improve visibility when working indoors without a detector.
6. When finished, power off the laser by pressing and ensuring the pendulum lock is engaged.

INSERTING BATTERIES

Model 99-026K includes a NiMH battery pack and charger for convenience but also can operate on AA batteries.

1. To insert the NiMH battery pack, loosen the battery cover screw and insert both NiMH battery packs. Next, plug in the battery connector to the pin terminals located between the batteries. The pin terminals are keyed to prevent erroneous installation.
2. All other models require 4xAA batteries (included). Loosen the battery cover screw, and remove any existing batteries. Install 4xAA batteries according to the polarity indicated on the laser.
3. If you will not use the laser for a long time (approximately one month or longer) it is recommended to remove the batteries to prevent drainage and/or corrosion.

USING THE PENDULUM CLOCK

The pendulum lock is located on the left side of the laser. Rotate it clockwise to lock the pendulum (for transport or vertical operation) or counterclockwise to unlock the pendulum (for horizontal operation).

• LOCK the pendulum for transportation and vertical operation.
• UNLOCK the pendulum for horizontal operation.
•  Note that UNLOCKED is also called “ON,” indicating the laser can be powered on in horizontal operating mode.

VERTICAL OPERATION

To operate the laser in vertical mode:

1.  Mount the laser vertically to a tripod or other stable surface
2. Keep the pendulum LOCKED. This will stabilize the pendulum.
3. Level the laser by turning the vertical leveling screw (located below the operation panel) until the bubble is centered within the vial.

USING THE LASER DETECTOR

Laser detectors locate the laser beam when you otherwise can’t see it with your naked eye, such as when working outdoors, in high ambient light, and over long distances.
Models 40-6516 & 99-026K include Johnson’s 40-6700 detector, and models 40-6517, 99-002K & 99-006K include Johnson’s 40-6705 detector. All models are compatible with all Johnson red beam rotary laser detectors, including the machine-mounted detector model 40-6791 that mounts to skid steers, excavators, and other equipment.

HOW TO USE THE LASER DETECTOR

1. Specifics and features vary slightly with each model – consult your manual for the specifics of your detector.

2.  Press (40-6700) or (40-6705) to power the detector on.

3. Adjust the volume by pressing (40-6700 only).

4.  Adjust the accuracy by pressing (40-6700 only). Use fine accuracy for critical work (+/-0.04″) and coarse accuracy (+/-0.1″) for rough work or quickly locating the grade position.
   Note: Fine accuracy will show the symbol on the LCD.

5. Pass the detecting window through the beam. The detector will beep (if the volume is on), and the LCD arrow or LED’s will indicate the direction to move the detector to locate the beam.

6. When the detector is on grade, the beep will become a solid tone, and the LCD arrow will become a solid line in the center of the LCD (406700), or the green LED will illuminate (40-6705) to indicate you are on-grade.

ROTARY LASER APPLICATIONS

Your new rotary laser is a versatile tool. You will constantly find new uses around your Jobsite where your rotary will help you complete your work faster, safer and smarter. Complete your leveling tasks with ease, and complete layout work in record time with your new laser.
FENCING, POST SETTING & EXCAVATION
Set common fence post heights, determine excavation depth, and complete square alignment work using the laser’s 90° split beam. Layout concrete formwork.

DROP CEILINGS
Rotary lasers are the perfect tool for drop ceilings. Mount a rotary just below your ceiling, and use a magnetic laser target or detector to find the beam.

PLUMB & ALIGN WALLS
Use the rotary in vertical mode with the 90° split beam to layout wall locations at perfect right angles. When erecting the walls, use the laser to ensure the walls are plumb, and for setting drywall track.

GRADING
The conventional use for rotary lasers, you can easily level or slope large areas of land for proper drainage. Pair with a grade rod and a detector, or use a machine mounted detector like Johnson’s 40-6791 to simplify large grading jobs.

CABINETS, WAINSCOTING & FINISH WORK
Use the laser to layout kitchen cabinets (both horizontal and vertical alignment), shelving, wainscoting, chair rails and more. You can also install tile on walls and floors, and transfer layout lines from floor to ceiling.

We want to get you up and running as quickly as possible – but this quick start guide is not a replacement for reading and understanding your operator’s manual! For complete safety & operating instructions, refer to the operator’s manual included with your rotary laser, or scan the QR code.
