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 accu-
racy 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 lev-
eling 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 plas-
tic 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 cen-
tre 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 ben-
zene, paint thinner, or other solvents to clean the instrument.

ENVIRONMENT PROTECTION

Recycle raw materials instead of disposing as waste.The machine, acces-
sories and packaging should be sorted for environmentalfriendlyrecycling.
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.
