POWER
NiCad or Nimh rechargeable batteries do NOT work well in a Laser Level as their operating voltage
is too low. We recommend that only alkaline batteries be used in your Laser Level. Plain carbon
batteries can leak either fluid or corrosive gas, both of which can damage the Laser Level.
It should be noted that the electronic switch in the Laser. Your LM30 will provide approximately 60
hours of intermittent use.
The "Low Battery" LED will light when the batteries' voltage falls below an optimal level. Also, if
your LM30 fails to emit laser beams, but still has
functioning LEDs and rotation, your batteries may be low; try replacing the batteries before
contacting a service center.
Replacement batteries must be all new batteries; alkalines provide the best performance.
Replace the batteries as follows:
1. Remove the battery cover by turning the battery cover screw counterclockwise.
2. Remove the old batteries and replace with four new "C" cell batteries as illustrated (Fig. 7),
and replace the battery cover.
NOTE: Do not mix old and new batteries. Replace all batteries at the same time with new batteries.
Remove batteries before storage of the instrument .
CALIBRATION
All Laser Levels are calibrated during assembly and Q.A., howeverLaserLevel owners should
always check the calibration of the unit before use as the settings may have changed with time or
during transportation. It is also wise to recheck the calibration of the Laser Level at regular
intervals and also prior to any critical measurements being performed. A 0.059"(1.5mm) Allen key
will be required to adjust the screws on the two leveling vials, and a 5/64" (2mm) one to adjust the
LD vial.
Checking Horizontal Rotation Error
1. Mount and level the LM30 on a tripod and place approximately 50 feet (15m) away from a
wall. Face the front (control button) to the wall (Fig.8).
2. Turn power on and place the unit in "STOP" mode.
3. Manually rotate the laser beam onto the wall and mark as point A.
4. Loosen the LM30 from the tripod and rotate the instrument 180° so that the back (battery
side) now faces the wall.
Secure and re-level the instrument.
5. Again rotate the laser beam onto the wall and mark its position as point B. No adjustment is
necessary if the vertical difference between points A and B is 1⁄8 inch (3mm) or less.
Otherwise, adjust as follows.
