• Position the tool so that the X-axis is parallel with the
vertical surface.
• Switch on the tool and rotate the head until the laser dot
appears on the vertical surface.
• Mark the centre of the laser beam. Switch off the tool.
• Switch off the tool and rotate it 180° so that the X-axis is
parallel with the vertical surface the other way around.
• Switch on the tool, rotate the head and once again mark
the centre of the laser dot on the surface. Switch off the
tool.
• Measure the difference between the markings.
• If the difference between the markings is 3.2 mm or
less, the laser head is properly calibrated.
• If the difference between the markings is more than 3.2
mm, the laser head must be calibrated.
To perform a check of the Y-axis:
• Position the tool so that the Y-axis is parallel with the
vertical surface.
• Following the same procedure as described above,
mark the centre of the laser dot on the surface with the
tool in this position, after which the tool is rotated 180° to
mark the centre of the laser dot once again.
• Measure the difference between the markings.
• If the difference between the markings is 3.2 mm or
less, the laser head is properly calibrated.
• If the difference between the markings is more than 3.2
mm, the laser head must be calibrated.
Plumb check
The following check is performed to check the calibration
of laser head for plumb alignment.
• Place the tool in an area at about 1 m from a vertical
surface.
• With the tool in a floor set-up, adjust the tool for a plumb
application.
• Mark the top and bottom of the vertical surface using a
plumb bob.
• Switch on the tool and align the laser beam with the
lower marking.
• Using the remote control, move the head until the laser
beam is at the upper marking.
• If the laser beam aligns with the top marking, the laser
head is properly calibrated.
• If the laser beam does not align with the top marking,
the laser head must be calibrated.
Cleaning
• Unplug the charger before cleaning the housing with a
soft cloth.
• Remove the battery pack before cleaning your power
tool.
• Keep the ventilation slots clear and regularly clean the
housing with a soft cloth.
• When necessary, clean the lens using a soft cloth or a
cotton bud soaked in alcohol. Do not use any other clean-
ing agents.
Environment
Rechargeable battery pack
This long life battery pack must be recharged when it fails
to produce sufficient power on jobs which were easily
done before. At the end of its technical life, discard it with
due care for our environment:
• Run the battery pack down completely, then remove it
from the tool.
• NiCd and NiMH cells are recyclable. Take them to your
dealer or a local recycling station. The collected battery
packs will be recycled or disposed of properly.
Unwanted tools
Take your tool to an authorised DEWALT repair
agent where it will be disposed of in an
environmentally safe way.
