Attentions
- The laser device is sealed and calibrated at the plant to the accuracies specified.
- It’s recommended to carry out an accuracy check before its first use and periodic checks during future use especially for precise layouts.
- When not in use please power OFF the device and place the pendulum lock in its locked position.
- In Manual Mode, self- leveling is OFF. The accuracy of the beam isnot ensured to be level.
- Remove batteries if the device will not be used for several months.
- Do not store the laser device in direct sunlight or expose it to high temperatures. The housing and some internal parts are made of plastics and may become deformed at high temperatures.
- Exterior plastic parts may be cleaned with a damp cloth. Although these parts are solvent resistant, never use solvents. Use a soft, dry cloth to remove moisture from the device before storage.
- Store the device in its package when not in use. If storing for extended time, remove batteries before storage to prevent possible damage.

Indicate a potentially hazardous situation or an unintended use which, if not avoided, will result in death or serious injury and/or in appreciable environment or property damages.
Important instructions which must be adhered to in practice as they enable the product to be used in a technically correct and efficient manner.
Possible danger when use the device:
- The laser beam will harm eyes when aim to eyes directly.
- The device may produce a spark and light to dust or gas.
- When clean battery electrolyte, human fingers may be affected.
- The device may cause a hazardous radiation explosion.
- Laser exposure radiation damage.
Caution:
- Do not look straight into the laser beam.
- Do not use the device in inflammable and explosive environment.
- Remove the batteries to avoid the electrolyte leakage when not use the device.
- Do not try other functions that the device does not have itself.
- Do not attempt to alter the functions of the device in any way.
Maintenance:
Wipe off dirt with wet and soft cloth. If wet cloth does not work, use cloth with alcohol to clean the dirt. Be careful with the optical components ( such as optical lens ) : wipe with clean soft cloth or cotton swab with distilled water(as cleaning glasses or camera lens). Do not use harmful cleaning material.
