CALIBRATION CHECK
It’s possible for you to check the calibration of the laser. It’s recommended to check the
calibration of the laser before performing any levelling task. Calibration by yourself is only
approximate and the accuracy of the calibration will depend on the care with which you
proceed.
•
Place the instrument on a flat, level surface or a tripod 30m away from a wall or staff with a
detector.
•
Align the first axis so that it’s square to the wall or staff. Allow the laser to self level
completely.
•
Mark the position of the beam on wall or note the position of the beam from staff (P1).
•
Rotate the instrument 180° and allow the instrument to self level again.
•
Mark or note the position of the beam (P2).
•
Rotate the instrument 90° and align the second axis so that it’s square to the wall and
allow the laser to self level completely.
•
Mark the position of the beam on wall or note the position of the beam from staff (P3).
•
Rotate the instrument 180° and allow the instrument to self level again.
•
Mark or note the position of the beam (P4).
•
The instrument is within its accuracy specification if the 4 parts are within ±1 mm from the
centre.
MAINTENANCE AND SERVICE
•
The instrument is a precision measuring device and should always be handled with care.
•
Do not attempt to open the device. To ensure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment should be performed by authorized service centres.
Contact your dealer for more details.
•
Do not drop, knock or shake the laser level as this will affect precision.
•
Remove batteries when the instrument is not in use.
•
Keep the instrument clean at all times. Use a soft lint-free cloth for the body and lens tissue
for glass windows. Do not use abrasive cleaners or solvents.
•
Do not store the instrument in the hot areas, hot temperatures can short the life of
electronic device, damage battery, and warp or melt certain plastics.
•
Do not store the laser level in the cold areas. When the unit warms up to its normal
operating temperature, moisture can form inside where it may damage circuit board.
•
Avoid shock, vibrations, extreme heat and humidity.
•
Do not immerse the instrument in water.
•
Always turn the instrument OFF when storing, transporting or moving around the job site.
•
Calibration is recommended at least once a year or as needed.
•
When transporting the instrument, always make sure that it’s carried in its original tool
case. Never carry the product loose in a road vehicle.
