1. Insert the charger plug into the jack located at the back of
the laser.
2. Plug the charger into an electrical outlet (110 volts or 220 volts).
3. Charge it for 15 hours.

3.3 Later recharges

The GAT220 can be charged when working, if electricity is
available on the jobsite. Simply plug in the charger and keep
on working. You can also remove the battery, replace it with the
alkaline battery pack and charge the rechargeable batteries.
For optimum life of the battery, it is recommended to charge the
battery after fully discharged. To assure battery life, do not
charge over 20 hours. The battery and the charger can be
damaged if damp. Always store and charge your instrument in
a dry and covered place.

4. Checking and adjusting your GAT220

THIS CHAPTER IS VERY IMPORTANT.
Here are a few simple instructions to check your
GAT220 for calibration. The laser is a precision instru-
ment 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 espe-
cially 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.
The laser has 2 horizontal axes: X and Y, as indicated on the top of
the laser.
X'
Y'
8
Y
X
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 service center for calibration.
Check and calibrate in this order:
Check both sides of X axis.
• If X is within spec, proceed to check both sides of Y.
• If X needs calibration, calibrate X
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
Final X to Y check: compare X, X', Y, Y'

4.1 Calibration overview

Calibration is electronic, using the laser keypad. The optional
detector/remote control or optional small remote may also be used.
If the beam is visible, calibrate using the non-rotating point. If it's
too bright to see the beam, you'll use the detector and will need to
have the beam rotating. When you're in calibration mode, press
the rotation key (7) on the laser to rotate the beam.
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.
IMPORTANT:
When pressing an arrow key to move the beam for cali-
bration, 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.

4.2 Horizontal checking and calibration

4.2.1 Checking X axis
1. Place the laser on a flat surface or tripod 100 ft. (30 m) away from
a wall. Position so that X' (noted on top of laser) is facing the wall.
