BATTERY PACK
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
1. Press the battery unlock button --
see (1) in the diagram at right.
2. Supporting the battery, press battery
release (2) to remove it.
A) Battery Replacement
1. Raise the battery cover release
to remove the battery cover.
2. Insert 4 D batteries. The insertion
direction of the batteries is indicated
on the battery pack.
3. Attach the battery cover, inserting
the guide lips into the guide slots.
B) Recharging (optional NiCd pack)
1. Remove charging connector cap on the
battery pack and plug in the charger.
2. Plug charger into electrical outlet. A
red light on the charger indicates it’s
charging.
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, it’s
recommended to charge the battery
after fully discharged. To assure battery
life, do not charge over 20 hours.
C) Installing the Battery Pack
1. Fit the guide posts of the battery into
the guide slots of laser.
2. Attach the battery to the laser by
pressing the top of the battery against
the laser until a click is heard.
CALIBRATION
Calibration should be checked regularly. For convenience you should establish a
range for routine and quick checks. Your AGL dealer can assist you in setting up one.
Allow at least 15 minutes of warm-up time before checking or adjusting calibration.
Steps 1-7 deal with checking calibration. If adjustment is needed, Steps 8-12 explain
the procedure. Follow the instructions carefully.
Checking Calibration
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.
2. Position laser so one axis is aligned toward pole at end of range.
3. Turn laser on and allow to level.
4. Using a detector, mark elevation of beam at pole (this is mark A).
5. Rotate laser 180˚ so the axis is again aligned with pole but in opposite direction.
Use detector again to mark elevation of beam on pole (mark B).
6. If marks “A” and “B” are within 1/8” (2.5 mm), calibration is correct.
7. Repeat the above procedure for the other axis. If marks are more than 1/8”
(2.5 mm) apart, proceed to Step 8 for calibration adjustment.
Calibration Adjustment
8. Make new “A” and “B” marks (repeat Steps 2-7). Make a third mark halfway
between the new “A” and “B”. Call this mark “C”. This is the correct beam center.
9. The calibration port for each axis is located on the top front of the laser (see
photo in Laser Overview). Choose the port matching the axis you are calibrating.
Open only one cover at a time to avoid adjusting the wrong axis.
10. Using a small screwdriver, carefully turn the exposed calibration port until beam is
centered at mark “C”. Make adjustments in
small, careful increments. After each
adjustment, check beam movement at
the pole.
11. Double check the axis. Rotate the laser 180˚
and again check the beam. Beam should
now strike within 1/16” (1.5 mm)of mark
“C”. If not, repeat Steps 8-10, adjusting as
needed until axis is calibrated.
12. Repeat Steps 2-11 for the other axis.
Calibration is complete when mark
“C” is the same for both axes in both
directions.
