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.

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.
