VAL 300 Operation
wc_tx000802gb.fm EN-16
2.9 Laser Detector
Your laser transmitter is provided with a laser detector to be used with
a grade rod or handheld applications. Detectors are recommended
when it is difficult to see the laser beam, such as outdoors or in bright
light.
If you cannot pick up the beam with the detector, check how you are
lined up with the laser. One of the head protection supports on the
laser may be blocking the beam; move to the left or right to receive the
beam.
The head protection may be removed from the laser by pivoting the
two security locks. This will not affect the performance or the water or
dust resistance of the laser.

Maintenance VAL 300
wc_tx000805gb.fm EN-19
3. Maintenance
3.1 Checking and Adjusting
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 50 degrees F (28 degrees
C) have occurred.
See graphic: wc_gr004580
The laser has two horizontal axes: X and Y, as indicated on the top of
the laser.
Each end of each axis must be checked for calibration. If needed, the
axis can be calibrated, carefully following the instructions. You can
also take the laser to a Wacker Neuson service center for calibration.

VAL 300 Maintenance
wc_tx000805gb.fm EN-20
Check and calibrate in this order:
3.1.1 Check both sides of X axis.
• If X is within spec, proceed to check both sides of Y.
• If X needs calibration, calibrate X
3.1.2 Check both sides of Y axis.
• If Y is within spec, proceed to final X to Y check
• If Y needs calibration, calibrate Y; proceed to X to Y check
3.1.3 Final X to Y check: compare X, X', Y, Y'
3.2 Calibration Overview
3.2.1 Calibration is electronic, and is accomplished by using the laser
keypad. The optional detector/remote control or optional small remote
may also be used.
3.2.2 If the beam is visible, calibrate using the non-rotating point. If it is too
bright to see the beam, calibrate using the detector while the beam is
rotating. When you're in calibration mode, press the rotation key (7) on
the laser to rotate the beam.
3.2.3 The axis LED should blink slowly when in calibration mode. When the
laser is self-leveling or making an adjustment, the LED will blink
rapidly.
3.2.4 IMPORTANT: When pressing an arrow key to move the beam for
calibration, use short, rapid clicks. Do not hold the key down. One click
will move the beam a very small amount (1/32" at 150' or 1mm at
100m). After pressing the key, the LED will blink rapidly as the laser
reacts. Wait until the LED returns to a slow blink to proceed.
