Operation

Initial Operation

•Protect the tool against moisture and direct sun irradiation.

•Do not subject the tool to extreme temperatures or variations in temperature.

As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the

tool to adjust to the ambient temperature before putting it into operation.

•Avoid heavy impact or falling of the tool. Damage to the tool can impair its accuracy.After heavy impact or shock, compare the laser line with a known horizontal or vertical reference line.

•Switch the tool off during transport. When switching off, the leveling unit, which can be damaged in case of intense movement, is locked.

Switching On and Off

To switch on the tool, push the On/Off

switch 3 to the “On” position. Immediately after switching on, the tool sends two laser beams out of the exit opening 1.

•Do not point the laser beam at persons or animals and do not look into the laser beam yourself, not even from a large distance.

To switch off the tool, push the On/Off switch 3 to the “Off” position. When switching off, the levelling unit is locked.

•Do not leave the switched on tool unattended and switch the tool off after use. Other persons could be blinded by the laser beam.

Automatic Leveling

Working with Automatic Leveling (see figures A-B)

Position the tool on a level and firm support, hold it by the contact surfaces 6 against a vertical surface or attach it to a tripod 11.

After switching on, the leveling function automatically compensates irregularities within the self-leveling range of ±4°. The leveling is finished as soon as the laser beams do not move any more. The indicator 2 lights up green.

If the automatic leveling function is not

possible, e. g. because the surface on which the tool stands deviates by more than 4° from the horizontal plane, the indicator 2 lights up red and the laser is automatically switched off. In this case, bring the tool to the level position or hold it by the contact surfaces 6 straightly against a vertical surface, and wait for the selfleveling to take place. As soon as the tool is within the self- leveling range of ±4° again, the indicator 2 lights up green and the laser beams are switched on.

When not within the self-leveling range of ±4°, working with the tool is not possible, because it cannot be assured that the laser beams run at a right angle to each other.

In case of ground vibrations or position changes during operation, the tool is automatically leveled in again. To avoid errors, check the position of the horizontal and vertical laser line with regard to the reference points upon re-leveling.

Working Advice

•Always use the center of the laser line for marking. The width of the laser line changes with the distance.
