IMP RTANT: t 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 laser is off before removing
and replacing battery packs.
Alkalin Batt ry Pack Installation
1. Put 4 “C” batteries into the battery pack
according to polarity direction.
2. Attach the battery pack to the laser.
Ni-MH R charg abl Batt ry Charging
Using the 6.4V battery adapter (included), charge the
rechargeable battery pack directly to the battery pack
(Fig 1.) or while the battery pack is connected to the
laser (Fig. 2). When the charge indicator LED turns
from red to green (after approximately five hours) on
the 6.4V battery adapter (Fig. 3), the Ni-MH recharge-
able battery pack has been fully charged.
Note:
(1) For the first two charges of new
rechargeable batteries, it is recommended
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.
Before Using the Laser
When you charge the new battery or one which has not been used for
long periods of time, it may not reach full charge until after you have
discharged it fully in use and recharge it several times.
Instrument Usage
1. Put in Ni-MH rechargeable battery pack, or 4 “C” alkaline battery pack.
2. Place the laser on a tripod, connect it to the tripod using the 5/8"
screw thread at the bottom of the laser.
Note: f the laser is inclined beyond the self-leveling
range, the laser will deliver an audible alarm. You will
need to re-position the laser.
3. Press power button to turn power on.
4. Press the Tilt button to lock in the height of the laser.
5. After finishing operation or before moving the laser, turn the power off.

Power n/ ff
1. Press the power on/off button to power the laser on. The
power LED will light up and the laser will electronically self-
level itself, with rotation occurring once the unit is level at 600
rpms. The laser will automatically enter into the Tilt mode and the
Tilt LED will flash slowly for 30 seconds then become solid.
2. Press the power on/off button again to power off.
Low Battery Indication
f the power LED is flashing, the battery is low. To ensure normal
operation, replace alkaline batteries or charge the rechargeable
Ni-MH battery pack.
Alarm If Beyond Range
f the laser is inclined beyond the self-leveling range of ±5°, it will
deliver an audible alarm, and will not rotate. You will need to
re-position the laser until it is within the leveling range.
Tilt Mode Button
After turning on the laser, the laser will self-level and begin to
rotate. The Tilt mode LED will blink for 30 seconds after the
laser begins to rotate. During these 30 seconds if the laser is moved,
the laser will stop rotating, re-level and begin to rotate again. After 30
seconds, the Tilt mode LED will stop blinking and will become solid. f
the laser is moved when the Tilt mode LED is solid, the laser will stop
rotating. The laser beam will blink on and off and the Tilt mode LED
will blink quickly alerting the user the height of the laser may have
been changed. Pressing the tilt mode button on the laser keypad will

turn off the tilt mode and will allow the laser to re-level and start
rotating again. Press the tilt mode button again to enter tilt mode.
Vibrate V-W-S Button
Press the Vibrate V-W-S button and the Vibrate V-W-S LED
will turn on, which means the laser is in vibrate mode.
Vibrate mode allows continuous operation during high winds,
vibrations and shocks. Slight movements are ignored and the laser
only enters Tilt mode if significant movement occurs. Press the
Vibrate V-W-S button again to turn vibrate off.

Detector Usage
Two-Sided Laser Detector with Clamp Model No. 40-6715
The 40-6715 aser detector is an indispensab e accessory when
using rotary aser eve s. The main function of the detector is to
detect the position of the aser signa s that are transmitted by rotary
asers. This detection quick y and precise y provides the user with the
horizonta and vertica references.
This product features high sensitivity, a doub e-faced disp ay, ow
power consumption, good re iabi ity and easy manipu ation. It can be
used with most types of rotating asers.

1. When detecting a horizontal laser signal, it is
important to have the horizontal bubble vial
centered, as the deflection of the receiver will
influence its receiving accuracy.

2. When detecting a vertical laser signal, it is important
to have the vertical bubble vial centered, as the
deflection of the receive will influence its receiving
accuracy.
3. Keep the reception window facing the laser while detecting.
4. Hold the unit stable while detecting.
LED Function
Power on and press the LED key, the LCD will now be backlit.
Automatic Shut-off Function
When the unit does not receive a laser signal for 6 minutes, the
unit will power off automatically.
Low Batt ry Display Function
When the battery sign blinks on the LCD, the battery is
low and needs to be replaced. f the battery is very low,
the unit will power off automatically. Replace the battery.

8. Self-Check and Fine Calibration
IMP RTANT: t is the responsibility of the user to verify the
calibration of the instrument before each use.
The instrument must be self-checked before operation. f the
accuracy is found beyond tolerance, user can make adjustment
according to directions as follows.
X-Direction Accuracy Self-Check
1. For clarity, we define the direction of handle as X-direction,
and the other direction as Y-direction
2. Place the unit on a platform or tripod that is 50’ away from a
wall indoors, with the handle facing the wall head-on. Turn the
unit on.
3. Using the detector mark on the wall where the beam hits the wall
and mark the beam as point A.
4. Turn the instrument by 180 degrees, mark the beam as point B.
5. Measure the vertical distance between point A and point B. f A &
B are more than 1/32" apart at 50’, the unit is out of calibration.
6. As shown, turn the instrument by 90° and place it on the
platform, with the operating panel facing you. Perform

50’
8488H-English_Manuals 11/11/14 2:36 PM Page 18

©2015 Johnson Level & Tool 19
Y-direction self-check with the same method as X-direction
self-check, and mark point C and point D by turns.
7. f point C and point D are within 1/32" at 50’, the accuracy is
within tolerance. Otherwise reference section 12 of this
document.
Fine Calibration via Remote Control (sold separately)
1. Access calibration mode by simultaneously pressing the
“Power” and “Tilt” buttons on the keypad.
2. Press on/off button and Tilt mode button at the same time,
then release the on/off button and continue pressing the Tilt
mode button. After the Tilt LED and V-W-S LED start to flash,
release the Tilt mode button and the instrument will enter into
X-calibration status, the Tilt LED flashes and V-W-S LED light
is on and the instrument keeps rotating.
3. Release the “Tilt” button. Note that the rotating head of the
laser is not rotating and the laser is flashing. The unit is now in
calibration mode and all other operations will be performed
with the unit’s remote control (sold separately).
4. Use the remote control to access the calibration.
Pressing the “X/Y” button changes calibration control between
the X-axis and Y-axis. The X-axis is selected when the Tilt
button is flashing while all other buttons are solid. The
Y-axis is selected when the V-W-S light is solid. Once the
desired axis has been selected, the “UP Arrow” and “Down
Aarow” buttons are used to adjust the position of the
horizontal laser beam plane.

X-axis Calibration
1. Place the unit into calibration mode as discussed above.
2. Position the unit so that the X-axis is directing to the target.
3. Press “X/Y” key on the remote control to toggle calibration
control to the X-axis.
4. Press the “UP Arrow” and “Down Arrow” buttons respectively
to adjust the laser height to coincide with the zero position of
the target.
5. Press the “Enter” button on the remote control to accept the
calibration value, noting that the status indicator goes “off”.
6. After calibration is completed, make sure to power off the unit
and then power on again to activate the calibration.
Y-axis Calibration
1. Place the unit into calibration mode as discussed above.
2. Position the unit so that the Y-axis is directing to the two targets.
3. Press “X/Y” button on the remote control to toggle calibration
control to the Y-axis.
4. Press the “UP Arrow” and “Down Arrow” buttons respectively
to adjust the laser height to coincide with the zero position of
the target.
5. Press the “Enter” button on the remote control to accept the
calibration value, noting that the status indicator goes “off”.
6. After calibration is completed, make sure to power off the unit
and then power on again to activate the calibration.
