Maintenance
Your D
E
WALT power tool has been designed to
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper tool care and regular cleaning.
Field calibration check (fig. F5, L1 & L2)
The field calibration checks must be performed
securely and accurately to make a correct diagnosis.
Whenever an error is registered, have the tool
calibrated by a qualified repair agent.
Always have the laser head calibrated by
a qualified repair agent.
Level checks (fig. L1 & L2)
The following checks are performed to check the
calibration of laser head for level alignment.
• Place the tool in an area at about 15 m from a
vertical surface.
• With the tool in a tripod set-up, adjust the tool for
a level application.
To perform a level check of the X-axis (fig. L1):
• 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 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 level check of the Y-axis (fig. L2):
• 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 (fig. F5)
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 cleaning agents.
