4.
Turn the instrument OFF by pressing the POWER button and cycle through the various
functions to come to the OFF position.
Note: If the instrument appears to be within its self-leveling range and the LED continues to blink,
be sure the instrument contains good batteries. If the instrument fails to operate after
completion of step 3 above, contact customer service.
POWER
Remove the battery cover by sliding it towards the bottom of the instrument. If replacing batteries,
remove the existing batteries. Insert three "AA" cell batteries into the instrument. Check for
correct polarity.
Alkaline batteries offer the longest battery life when used in this instrument.
Note: Extreme temperatures and the use of batteries with different levels of charge can reduce
the operating time of the instrument. Always use batteries with the same power rating and from
the same manufacturer. For the proper disposal of the used batteries, see the section
"Environmental Protection".
MAINTENANCE AND CARE
DO NOT allow laser tool to get wet. The laser tool is not waterproof. Damage to internal circuits
will result
DO NOT leave the laser tool in direct sunlight or exposed to high temperatures. High temperature
may cause internal parts made of plastics to deform.
DO NOT store laser tool in cold environment. Moisture can form on interior parts when warming
up. This may cause laser windows to fog and corrosion to internal circuit boards.
DO NOT use aggressive cleaning agents or solvents to clean laser tool.
REMOVE moisture or dirt from laser windows with a soft, dry cloth.
ACCURACY CHECK
As with any level reference instrument, we strongly recommend checking the instrument's
calibration before initial use; then periodically to ensure proper reference.
Check the laser Instrument following these steps:
Checking the horizontal line front to back (Fig. 4)
1.
Choose two walls approximately 16-ft (5m) apart.
2.
Set up the instrument 1-ft from wall (W1), project the laser cross onto wall. (W1) and mark
the point "A1" where the laser cross hits the wall.
3.
Rotate the instrument 180° and project laser cross onto the opposite wall. (W2) and mark the
point where the laser cross hits the wall "B1".
4.
Reposition the instrument 1-ft from wall (W2), project the laser cross onto wall. (W2) and
mark the point "B2" where the laser cross hits the wall.
