Operation Instructions

IMPORTANT

• It is the responsibility of the user to verify the calibration of the instrument before each use. See section 7.

Using the 3×360° Plane Laser

Mounting Positions

• The Johnson 3×360° Plane Laser can be mounted in a variety of positions, depending on your needs.
• Place the unit in an upright position, either on a stable, flat surface, mount it to a tripod with a 1/4″-20 threaded screw, mount it to a ferrous surface using the magnets, or hang it on a nail using the mounting hole. Non-mar rubber feet on the unit prevent damage to surfaces. (Figure 9)

Using Track Mount Accessory

Operation

1. To attach the track clip to a vertical surface, first attach the top screw to the vertical surface, then hang the track clip onto the top screw. Secure the track clip by attaching the second screw to the bottom of the track clip. (Figure 10)
2. Clamp the track mount to ceiling channels, racks, etc., by squeezing the track mount release lever to open the track clip. Slide the track mount assembly onto the channel and release the lever. (Figure 11)
3. To attach the unit to the track mount, place the unit’s magnets on the metal plate. Slide the unit up or down to adjust its position. (Figure 12)

Using an Optional Mounting Bracket Accessory

Using an optional multi-functional base accessory (#40-6422), the unit can be used in even more positions including hanging from an elevated ferrous surface, mounted to a 5/8″-11 threaded screw, or insert mounting straps into slots for mounting on non-ferrous surfaces. (Figure 13).

Operation

1. To attach the optional base accessory to the unit, place the unit’s magnets on the metal plate, making sure the locking tabs snap into place on the rear of the laser base. (Figure 14)
2. The optional base accessory can be mounted to the unit in a variety of configurations: seated on the base, hanging from the base, or rotated 90° on the base. (Figure 15)
3. To make micro adjustments to the vertical position of the laser, push the micro-adjust knob on the base accessory in to unlock it. Rotate the knob to raise or lower the attachment plate. The position can be adjusted from 1/32″ to 1″. Release the knob to lock the position. (Figure 16)

Using the Unit in Automatic Mode

IMPORTANT: If the unit’s position changes after it has self-leveled, verify the unit’s position (for example, height) to the potentially changed conditions.

1. Slide the locking compensator/power switch to the left to the unlocked (ON) position to power on the unit. The level indicator and power indicator will light up. (Figure 17)
   • Power/Battery LED: Steady green LED indicates power is on and battery power is greater than 30%.
   • Steady red LED indicates power is on and battery power is between 30% and 15%.
   • Flashing red LED indicates power is on and less than 10%. Charge or change the batteries.
   • Extinguished LED indicates power is off or battery has been depleted.
2. On the keypad, press the button to turn on the horizontal laser beam. Press the button to turn on the right vertical laser beam. Press the button to turn on the front vertical laser beam. The unit can be used with any combination of laser beams turned on simultaneously. Disabling a laser you are not using extends the life of the battery.
   • NOTE: The unit must be within ±4° of level for the self-leveling feature to function properly. If the unit is beyond its 4° self-leveling range, the laser will not self-level, the laser will flash, and the level indicator status light will flash red. Once the unit has been adjusted to within its 4° self-leveling range, the laser will self-level, the status light will turn green, and the laser light will stop flashing and remain solid.
3. When using the vertical (plumb) laser beam, rotate the unit to the desired position. Use the Fine-tuning adjustment knob to make small adjustments. (Figure 18)
4. Slide the locking compensator to the right to the locked (OFF) position to power off the unit. (Figure 19)

Using the Product in Tilt (Manual Level) Mode

The pendulum lock secures the laser during transport to prevent damage to the self-leveling mechanism. It also enables the laser to be used at any angle in manual mode.

1. The unit can be used to project laser beams at any angle desired, such as when projecting a line for stairs or a railing. This mode produces the best results when the unit is mounted on a tripod. With the locking compensator in the locked (OFF) position, press and hold any of the buttons on the keypad for three seconds to power on the unit. The status lights will illuminate. The level indicator LED will light a steady red to indicate the unit is not self-leveling.
2. On the keypad, press the button to turn on the horizontal laser beam. Press the button to turn on the right vertical laser beam. Press the button to turn on the front vertical laser beam. The unit can be used with any combination of laser beams turned on simultaneously. Disabling a laser you are not using extends the life of the battery. The lasers will not self-level.
   • NOTE: While in Manual Level mode, active lasers will flash three times, at one second intervals, every 15 seconds. This is a visual indication that the unit is in Manual Level mode and will not selflevel.
3. When using the vertical (plumb) laser beam, rotate the unit to the desired position. Use the Fine-tuning adjustment knob to make small adjustments.
4. Press any of the laser beam buttons for three seconds to power off the unit.

Using the Target

• The target is used to enhance the laser beam visibility. The target uses magnets for easy mounting to ferrous surfaces in either horizontal or vertical positions.
• It has measurements in both English and Metric scales (inches/cm). This item is for use with green laser levels. (Figure 20)

Accuracy Check

Before starting any critical work, check your laser for accuracy.

Plumb Line Accuracy

NOTE: This test should be done indoors with dim lighting. It is critical that the laser mark is easily seen.

1. Position laser at Point 1, 10′ from a doorway.
2. Mark beam at Point 1.
3. Mark beam at Point 2, 20′ away.
4. Mark Points C on the floor under doorway and D on doorway.
5. Move laser near Point 2. Aim the beam through Points 2, C, and 1. Mark Point E next to D on doorway.
6. If the distance D to E <1/16″ for a 10′ doorway, your plumb accuracy is within specification. (Figure 21)

Horizontal Line Accuracy

Check accuracy using two walls 20′ apart.

1. Set laser next to Wall A. Mark beam height on Wall A as point A1. (Figure 22)
2. Rotate laser 180°. Mark beam height on Wall B as point C. (Figure 23)
3. Set laser next to Wall B and adjust beam to height C. (Figure 24)
4. Rotate laser 180°. Mark beam height on Wall A as A2. (Figure 25)
5. Measure the vertical distance between A1 and A2. If this distance is <1/16″ at 20′, your horizontal accuracy is within specification.

NOTE: If your laser needs non-warranty service or calibration, return it to a Johnson authorized service center for repair.
