DeWalt DW073 Mode D'emploi page 37

With tool in tripod set-up (fig. E3):
• Adjust the tripod to set the tool to the required
height.
Plumb alignment (fig. E4)
• With the tool switched on and the laser head
rotating, align the laser line with the position mark.
• If adjustment is required, proceed as follows:
• Loosen the locking knob (16) and adjust the rack
pinion wheel (13) to set the tool to the correct
position. Tighten the locking knob (16) (fig. E4).
• Turn the level adjustment knob (30) until the head
aligns with the position mark.
Instructions for use
Always observe the safety instructions
and applicable regulations.
• Always mark the center of the laser line or dot.
• To increase working distance and accuracy,
set up the tool in the middle of your working area.
• Make sure the tool has been set up securely.
• Extreme temperature changes cause movement
of internal parts that may affect the accuracy of
the tool. Regularly check the accuracy while
using the tool under these circumstances.
• Regularly check whether the tool has registered a
bump. When it has registered a bump,
re-adjustment to balance or set-up may be required.
• If the tool has been dropped or has tipped over,
have the calibration system checked by a
qualified repair agent.
Switching on and off (fig. A)
• To switch the tool on, turn the switch (1) in the
clockwise direction.
• To switch the tool off, turn the switch (1) in the
anti-clockwise direction until it clicks in place.
Setting the rotation speed (fig. F)
The variable speed switch (1) can be used for advance
setting of the rotation speed, which helps determining
the quality of the line. The rotary head remains
stationary in the first quarter of the setting range.
• Turn the switch (1) as desired. Turning the switch
in the clockwise direction increases the rotation
speed. Turning the switch in the anti-clockwise
direction decreases the rotation speed.
27
• For a stationary dot, set the switch in the first
quarter of the setting range.
• For a bright line, set the switch to a slow rotation
speed.
• For a solid line, set the switch to a fast rotation
speed.
Manually rotating the laser head (fig. G)
In the stationary position, the laser head can be
rotated manually.
• Depress the rotation button (7) and while keeping
the button depressed turn it to rotate the laser
head (8) into the required position.
Do not attempt to depress the rotation
button while the laser head is rotating at
a preset rotation speed.
Bump sensor (fig. H)
The bump sensor responds to any bump that may
affect the tool's balance or set-up. Once it registers
a bump, the indicator light (28) goes blinking.
• To reset the bump sensor, press the button (2).
The indicator (28) stops blinking.
Activating the bump sensor interruption
With the bump sensor interruption activated, once a
bump is registered the rotating laser head stops
rotating while the laser beam starts flashing.
• To activate the bump sensor interruption, press
the button (3). The indicator (29) lights up.
• To reset the bump sensor, press the button (2).
The indicator (28) stops blinking and the tool
returns to normal operation.
Tool aids (fig. I1 & I2)
Several aids have been supplied that might be
helpful while operating the tool.
Laser enhancement glasses (fig. I1)
The red lens glasses improve the visibility of the laser
beam under bright light conditions or over long
distances. Providing best results indoors, the lens
filters out ambient light and intensifies the projected
dot or line. The glasses do not keep the laser beam
from entering the eyes.
