2 Operation
2.1 Application
This Wacker Neuson laser transmitter is simple to use, yet it has
several advanced features:
• Automatic self-leveling in horizontal
• High precision
• Ideal for screeding, general construction, site preparation, and
other leveling applications
2.2 Calibration
It is important to check your laser for proper calibration. The laser is a preci-
sion instrument and it is important that you keep it calibrated and in proper
condition. The accuracy of your work is completely your responsibility and you
should check your instrument before beginning each job, and especially after
the instrument has taken a sharp jolt or been dropped, or when temperature
changes greater than 50 degrees F (28 degrees C) have occurred. See “Main-
tenance” for calibration procedures.

2.4 Using the Laser
See Graphic: wc_gr004579
Setup:
The laser mounts to any 5/8" x 11 tripod (flathead or domed) or can
rest on any stable flat surface (floor, bricks, etc.). Position the tripod,
attach the laser, then adjust the tripod until it is rough leveled (within ±
4° self-leveling range).
Turning on the Laser:
Press the ON / OFF key (4) to power up the laser. The unit's self-
checking system will start automatically. Both LEDs (5 and 6) will flash
if anything goes wrong during the self-check procedure. The battery
LED should be green. If batteries are low, the battery LED will be red
or both LEDs will flash.
Leveling:
When the laser is turned on, the level indicator LED (5) will flash red
until the unit is level. If the laser fails to self-level within 90 seconds, the
LED will light and remain lit. Re-adjust the tripod to bring the laser into
self-leveling range. When the unit is level, the rotor head will begin
spinning at 600 rpm.
Level Alert:
If laser is disturbed, the level alert system will stop head rotation. The
laser will self-level and return to operation automatically unless it is
disturbed again while in the self-leveling range (± 4°). Always recheck
the beam height against a benchmark when releveling is required.
Power Sources:
The laser can be operated with the alkaline battery pack (4 D-size
batteries) or the optional NiCd rechargeable battery pack. If using a
NiCd battery pack, charge it completely before flrst use. The NiCd
battery pack can also be charged while working. If electricity is
available on the job site, simply plug in the charger and keep working.

3 Maintenance
3.1 Calibration overview
THIS SECTION IS VERY IMPORTANT: Here are a few simple
instructions to check your laser for calibration. The laser is a precision
instrument and it is important that you keep it calibrated and in proper
condition. The accuracy of your work is completely your responsibility
and you should check your instrument before beginning each job, and
especially after the instrument has taken a sharp jolt or been dropped,
or when temperature changes greater than 28°C (50°F) have
occurred.
Calibration should be checked regularly. For convenience, you should
establish a range for routine and quick checks. Your Wacker Neuson
dealer can assist you in setting up this range. Allow at least 15 minutes
for the laser to warm up before checking or adjusting calibration.
3.2 Checking Calibration
3.2.1 Select a level range at least 100 ft. (30 m) long. Set up the laser on a
flat surface or tripod. Approximately 100 ft. (30 m) away, erect a
vertical pole or rod.
3.2.2 Position the laser so one axis is aligned toward pole at end of the
range.
3.2.3 Turn the laser on and allow it to self-level.
3.2.4 Using a detector, mark the elevation of the beam at the pole. This is
mark “A.”
3.2.5 Rotate the laser 180° so the axis is again aligned with the pole, but in
the opposite direction. Use the detector again to mark the elevation of
the beam at the pole. This is mark “B.”
3.2.6 If marks A and B are within 1/8" (2.5 mm), calibration is correct.
3.2.7 Repeat the above procedure for the other axis. If marks are more than
1/8” (2.5 mm) apart, proceed to “Calibration Adjustment.”

PAL 450 Maintenance
wc_tx000807gb.fm EN-16
3.3 Calibration Adjustment
See graphics: wc_gr004603 and wc_gr004604
3.3.1 Make new “A” and “B” marks as directed in “Checking Calibration.”
Make a third mark halfway between the new A and B. Call this mark
“C.” This is the correct beam center.
3.3.2 The calibration port for each axis is located on the top front of the laser.
Choose the X axis port (2) or the Y axis port (3) as necessary. Open
only one cover at a time to avoid adjusting the wrong axis.
3.3.3 Using a small screwdriver, carefully turn the exposed calibration port
adjustment screw left or right until the beam is centered at mark C.
Make adjustments in small, careful increments. After each adjustment,
check beam movement at the pole.
3.3.4 Double check the axis. Rotate the laser 180° and again check the
beam. The beam should now strike within 1/16" (1.5 mm) of mark C. If
not, repeat steps 1–3, adjusting as needed until the axis is calibrated.
3.3.5 Check and adjust the calibration of the other axis. Calibration is
complete when mark C is the same for both axes in both directions.

3.4 Battery Pack
See graphic: wc_gr004602
To replace the alkaline batteries, or to charge the NiCd pack, first
remove the battery pack. The NiCd pack must be charged before first
use.
Removing the Battery Pack
3.4.1 Press the battery unlock button -- see (1) in the graphic above.
3.4.2 Supporting the battery, press the battery release (2) to remove it.
A) Battery Replacement
3.4.1 Raise the battery cover release to remove the battery cover.
3.4.2 Insert 4 D batteries. The insertion direction of the batteries is indicated
on the battery pack.
3.4.3 Attach the battery cover, inserting the guide lips into the guide slots.
B) Recharging (optional NiCd pack)
3.4.1 Remove the charging connector cap on the battery pack and plug in
the charger.
3.4.2 Plug the charger into an electrical outlet. A red light on the charger
indicates that it is charging.

PAL 450 Maintenance
wc_tx000807gb.fm EN-18
3.4.3 When the red light blinks (lights on for 6 seconds, off for 20 seconds),
the charging is finished. Charging time is about 7.5 hours. The unit can
be charged while working. For optimum life of the battery, recharge the
battery after it is fully discharged. To assure battery life, do not charge
over 20 hours.
C) Installing the Battery Pack
3.4.1 Fit the guide posts of the battery into the guide slots of the laser.
3.4.2 Attach the battery to the laser by pressing the top of the battery against
the laser until a click is heard.

Troubleshooting PAL 450
wc_tx000807gb.fm EN-19
3.5 Care and Handling
The use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation
exposure.
3.5.1 The laser is a precision instrument which must be handled with care.
Avoid shock and vibrations. Always store and transport the laser and
its accessories in the carrying case.
3.5.2 Although the laser is weather resistant, make sure to clean and dry it
with a soft cloth after each use. This will increase the battery life.
3.5.3 Do not store your laser at temperatures below -4°F (-20°C) or above
176°F (80°C) because some electronic components could be
damaged.
3.5.4 To avoid water condensation inside the instrument, do not store it
inside the case if the instrument or the case is wet.
3.5.5 To maintain the laser’s precision, check and calibrate the beam
regularly.
3.5.6 Keep the glass housing around the rotating head dry and clean. Use a
soft cloth and glass cleaner to clean it.
3.5.7 Charge the batteries regularly. However, charge them only when they
are nearly drained or completely out of power. Recharging batteries
that are still usable will shorten their capacity.
