SETTING UP
Correct set-up of any manual Laser Level is critical to the operation of the Level. These Laser
Levels do not adjust themselves automatically. The accuracy of the job depends entirely upon how
well the unit has been set-up. An error of only 0.02" (0.5mm) at the top of the tripod becomes an
error of 4" at 65 feet (100 mm at 20 meters). In order to achieve the accuracy required some special
precautions should be observed.
1. The head of the Laser Level is fitted with two engineering grade spirit leveling vials which are
extremely accurate and very sensitive. When the Level is being set-up the bubbles move quite
slowly and may even stick inside the vial. This is called stiction. The solution is to lightly tap the
non-rotating part of the Level with the tip of a finger until the bubble ceases to move.
2. When attaching the Laser Level to the tripod, the instrument fastening screw should not be
over-tightened. If the screw is tightened excessively then the trivet base will become distorted
and over a period of time the plastic material of the trivet will relax, particularly if the day is hot,
causing the setting of the Level to change. In extreme cases it is possible to pull the centre
insert out of the trivet.
MAINTENANCE
Always clean the instrument after use. Use a soft, dry cloth to remove any dirt or moisture from the
instrument. Store the unit in its case when not in use. Batteries should be removed before long-
term storage. Do not use benzene, paint thinner, or other solvents to clean the instrument.

ENVIRONMENT PROTECTION

Recycle raw materials instead of disposing as waste.The machine,
accessories and packaging should be sorted for environmental friendly
recycling. Do not throw used batteries into house waste, fire or water but
dispose of in an environmentally friendly manner according to the
applicable legal regulations.
