Maintenance And Care; Accuracy Check - CST/BERGER LASERMARK 58-ILMXT Manuel D'instructions

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 tool, we strongly recommend checking the calibration before initial
use; then periodically to ensure proper reference.
Check the Laser tool 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 laser tool 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 laser tool 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 laser tool 1-ft from wall (W2), project the laser cross onto wall (W2) and mark
the point "B2" where the laser cross hits the wall.
5. Rotate the laser tool 180° and project laser cross onto the opposite wall (W1) and mark the
point where the laser cross hits the wall "A2".
6. Measure the distance between "A1" and "A2" and between "B1" and "B2" . If the distances
are the same, the Laser tool is in calibration. If the difference between the two sets of points
is greater than 1/2 the specified accuracy the laser tool is out of calibration.
Checking the horizontal line side to side (Fig. 5)
1. Set the laser tool up approximately 8ft (2.5m) from a wall that is at least 16ft (5m) long.
2. Project the laser cross 1ft(0.3m) from one corner. Mark point (A) along the horizontal laser
line 8ft (2.5m) from the intersection of the laser cross.
3. Rotate the laser tool so that the laser cross is projected at the wall 15ft (4.6m) away from
the first laser cross point.
4. The deviation of the horizontal laser line from the point (A) marked previously should not be
greater than 1/2 the specified accuracy.
