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. In case of extreme temperatures or variations in temperature, the accuracy of the tool can be impaired.
•Avoid heavy impact or falling of the tool. After heavy exterior impact on the tool, an accuracy check should always be carried out before continuing to work (see “Leveling Accuracy”).
•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 4 forward so that “I” is indicated on the switch. Immediately after switching on, the tool sends a laser beam out of each 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 4 backward so that “0” is indicated on the switch. When switching off, the leveling unit is locked.
Setting the Automatic Switch-off
By default, the tool automatically shuts off 20 minutes after being switched on. The automatic switch-off can be set from 20
minutes to 8 hours. For this, switch the tool on, then immediately off, and then on again within 4 s. To confirm the change, all laser beams will flash quickly for 2 s after switching on the second time.
•Do not leave the switched on tool unattended and switch the tool off after use. Other persons could be blinded by the laser beam. When switching on the tool the next time, the automatic switch-off is set to 20 minutes again.
Working with Automatic Leveling
Position the tool on a level and firm support, attach it to the holder 8 or to the tripod 18.
After switching on, the automatic leveling function automatically compensates irregularities within the self-leveling range from ±5° (longitudinal axis) and ±3° (lateral axis). The leveling is finished as soon as the laser points do not move any more.
If the automatic leveling function is not possible, e.g. because the surface on which the tool stands deviates by more than 5° (or 3° from the horizontal plane) the laser beams flash rapidly.
In this case, bring the tool to the level position and wait for the self-leveling to take place. As soon as the tool is within the selfleveling range of ±5° or ±3° respectively, all laser beams light up continuously again.
In case of ground vibrations or position changes during operation, the tool is automatically levelled in again. To avoid errors by moving the tool, check the position of the laser beams with regard to the reference points upon re-leveling.
Working Advice
•Always use the center of the laser point for marking. The size of the laser point changes with the distance
Leveling Accuracy
Influences on Accuracy
The ambient temperature has the greatest influence. Especially temperature differences occurring from the ground upward can divert the laser beam.
As thermal fluctuation is largest close to the ground, the tool, if possible, should be mounted on a commercially available tripod and placed in the center of the working area.
Apart from exterior influences, devicespecific influences (such as heavy impact or falling down) can lead to deviations. Therefore, check the accuracy of the tool each time before starting your work.
Should the tool exceed the maximum deviation during one of the tests, see recalibration procedure or have it recalibrated by a Bosch after-sales service center.

Checking the Horizontal Leveling
Accuracy of the Lateral Axis
A free measuring distance of 78 ft on a firm surface in front of a wall is required for
the check.
–Mount the measuring tool onto the multipurpose attachment or a tripod, or place it on a firm and level surface at a distance of 78 ft to the wall. Switch the tool on.
Thus, the difference d between points I and II may not exceed 9/16 in (max.).
Checking the Horizontal Leveling
Accuracy of the Longitudinal Axis
A free measuring distance of approximately 78 ft on a firm surface between two walls A and B is required for the check.
–Mount the tool onto the multi-purpose attachment or a tripod, or place it on a firm and level surface close to wall A. Switch the tool on.

–Rotate the measuring tool by approx. 180° without changing its height. Allow it to level in and mark the center point of the other lateral laser beam on the wall (point II). Take care that point II is as vertical as possible above or below point I.
–The difference d of both marked points I and II on the wall results in the actual height deviation of the tool alongside the lateral axis.
On the measuring distance of 2 x 78 ft = 156 ft, the maximum allowable deviation is:
156 ft x ±0.0036 in/ft = ±9/16 in (.563).
–Turn the tool around by 180°, allow it to level in and mark the center point of the laser beam on the opposite wall
B (point II).
–Without turning the tool, position it close to wall B. Switch the tool on and allow it to level in.

d
–Rotate the tool by 180° without changing the height. Allow it to level in and mark the center point of the laser beam on wall A (point III). Take care that point III is as vertical as possible above or below point I.
–The difference d of both marked points I and III on wall A indicates the actual height deviation of the tool.
On the measuring distance of 2 x 78 ft = 156 ft, the maximum allowable deviation is:
156 ft x ±0.0036 in/ft = ±9/16 in(.563). Thus, the difference d between points I and III should not exceed 9/16 in (max.).
Checking the Vertical Leveling Accuracy
For this check, a free measuring distance of approx. 13 ft between floor and ceiling on a firm surface is required.
–Draw a straight line on the ceiling.
–Mount the tool to the multi-purpose attachment or a tripod. Switch the tool on and rotate it in such a manner that the bottom plumb beam can be seen on
the floor.
–Position the tool in such a manner that the upper plumb beam points against the line on the ceiling. Allow the tool to level in.
Mark the center of the upper laser point on the line on the ceiling (point I). Also, mark the center of the laser point on the floor (point II).
d
–Rotate the tool by 180°. Position it in such a manner that the center of the bottom laser point is directed on the already marked point II and the upper laser point is directed against the line on the ceiling. Allow the tool to level in. Mark the center of the upper laser point on the line on the ceiling (point III).
–The difference d of both marked points I and III on the ceiling results in the actual deviation of the tool to the plumb line.
On the measuring distance of 2 x 13 ft = 26 ft , the maximum allowable deviation is:
26 ft x ±0.0036 in/ft = ±3/16 in.
Thus, the difference d between points I and III should not exceed 3/16 in (max.).
Recalibration Procedure
All tools are calibrated when processed through the Bosch quality control program. This process assures that the customer receives a superior product which conforms to the Product Specifications. Although tools have been calibrated before reaching our customers, it contains many precision machined parts which may be affected if the instrument is subjected to abuse. Therefore, if the device is ever dropped or sustains
-9-
significant impact, the user should check calibration by following these steps:
1.Select a site to be used as a calibration range that will allow the tool to be placed between two smooth vertical surfaces directly opposite each other at a 100' distance. (50' minimum)
2.Remove the two calibration plugs on the rear and side of tool with a flathead screwdriver. Set the plugs where they will not be lost.
3.Set tool on a level surface at one end of the range.
4.Set the tool in calibration mode by pushing the power switch into the CAL (override) position and holding for 5 seconds or more. The laser beams will flash rapidly indicating that the unit is in Calibration mode when the power switch has been held in the ove rride position for 5 seconds or more. The laser beams will continue to flash rapidly until the power switch has been released from the CAL (override) position. When the power switch has been released from the CAL (override) position the laser beams will remain in a fast flash if the unit is level. If the unit is out-of-level, the laser beams will flash slowly until the device has reached a level position. To exit Calibration mode, push the power switch into the CAL (over ride) position and hold for 5 seconds. The laser beams will flash rapidly for the 5 seconds until it exits calibration mode. You can also exit Calibration mode by turning the power switch to the off position, waiting 2 seconds and back on for normal operation. Once out of calibration mode, the laser beams will remain steady if the device is level or the beams will flash slowly if the device is out-of-level. Release the power switch from the CAL(override) position. The unit then operates normally.

5.When in Calibration mode, position the side laser beam (on the calibration port side) on the vertical surface at the
opposite end of the range and mark this point on the surface. Verify that the laser beams are flashing fast confirming that the device is level and in
calibration mode.
6.Rotate tool around 180 degrees, taking care not to change the height of
the device.
7.Position the other side laser beam on the same vertical surface and mark this point on the surface. Verify that the laser beams are flashing fast confirming that the device is level and in
calibration mode.
8.If this second mark is positioned at the same height as the mark made in step 5, proceed to step 14, otherwise, proceed to the next step.
9.The goal of the next few steps is to position both side beams at a height halfway between the marks made in step 5 and in step 7.

10.Insert the provided tool into the side calibration port. Locate the calibration screw and rotate it in a clockwise direction to lower the beam or in the counter clockwise direction to raise the beam. Ensure that the beam is at a height exactly halfway between the
marks made in Steps 5 and 7. Mark this point on the surface.
11.Repeat Steps 6 through 10 to confirm the calibration of the side beams and proceed to the next step.
-10-
12.Rotate the tool around 90 degrees
and position the front laser beam on the vertical surface. Compare the height of this beam with the height of the calibrated side beams. If the height of this beam matches the height of the side beams, calibration is complete and you may exit calibration mode. To exit Calibration mode, push the power switch into the CAL (override) position and hold for
5 seconds. The laser beams will flash rapidly for the 5 seconds until it exits calibration mode. Once out of calibration mode, the laser beams will remain steady if the device is level or the beams will flash slowly if the device is out-of-level. Release the power switch from the CAL(override) position. You can also exit calibration mode by turning the power switch to the off position and back on for normal operation. If the front beam does not match the side beams, proceed to the next step.
13.The goal of the next step is to position the front beam at the same height as the last mark to be made in the previous steps or at the same height as the calibrated side beams. Verify that the laser beam are flashing fast confirming that the device is level and in
calibration mode.

14.Insert provided tool into the back calibration port. Locate the calibration screw and rotate it in a clockwise direction to the raise the beam or in the counter-clockwise direction to lower the beam.
15.Turn the tool and check the height of the front beam again.
16.Repeat steps 13 steps through 15 until the front beam matches the height of the two calibrated side beams and proceed to the next step.
17.Insert and screw the calibration plugs back into the tool Calibration is complete. Once out of calibration mode, the laser beams will remain steady if the device is level or the beams will flash slowly if the device is out-of-level. Release the power switch from the CAL(override) position. You can also exit calibration mode by turning the power switch to the off position, waiting 2 seconds and back on for
normal operation.
Applications
Plumbing a surface
1.Position tool close to the surface to be plumbed.
2.Turn on tool.
3.Measure distance A at a point relatively close to tool and make a note of
the distance.
4.Measure distance B at a point further away from tool and make a note of the distance.
Note: The greater the distance between the two points of measurement, the greater the accuracy.
5.Compare distance A with distance B. If distance A equals distance B, then the surface is plumb. If distance A does not equal distance B, then the surface is not plumb and should be corrected.
