of such accessories with this laser
could be hazardous. To reduce the risk
of injury, only D
EWALT-recommended
accessories should be used with this
product.
These are:
• DE0772 DEWALT Digital laser detector
• DE0734 DEWALT Grade rod
• DE0735 DEWALT Tripod
• DE0736 DEWALT Tripod
• DE0737 DEWALT Grade rod
• DE0738 DEWALT Gradient bracket
Consult your dealer for further information on the
appropriate accessories.
MAINTENANCE
Your DEWALT laser unit has been designed to
operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation
depends upon proper laser care and regular
cleaning.
• To maintain the accuracy of your work, check
the calibration of the laser often. Refer to Field
Calibration Check.
• Calibration checks and other maintenance
repairs can be performed by DEWALT service
centres.
• When the laser is not in use, store it in the kit
box provided.
• Do not store your laser in the kit box if the laser
is wet. Dry exterior parts with a soft, dry cloth
and allow the laser to air dry.
• Do not store your laser at temperatures below
-18˚C (0˚F) or above 41˚C (105˚F).
Field Calibration Check (fi g. 9, 10)
WARNING: Always have the laser head
calibrated by a qualified repair agent.
Field calibration checks should be done frequently.
NOTE: As part of the D
EWALT guarantee,
the owner is entitled to one FREE calibration
service within the first year. Simply complete
the enclosed voucher and return along with the
laser and proof of purchase to an authorised
D
EWALT agent. A certificate will be awarded at
no additional charge.
Field calibration checks do not calibrate the laser.
These checks indicate whether or not the laser is
providing a correct level and plumb line and do not
correct errors in the leveling or plumbing capability
of the laser.
These checks cannot take the place of professional
calibration performed by a D
EWALT service centre.
LEVEL CALIBRATION CHECK (X-AXIS)
1. Set up a tripod between two walls that are at
least 15 m (50 ft.) apart. The exact location of
the tripod is not critical.
2. Mount the laser unit on the tripod so that the
X-axis points directly toward one of the walls.
3. Turn the laser unit on and allow it to self-level.
4. Mark and measure points A and B on the walls
as shown in Figure 9.
5. Turn the entire laser unit 180º so the X-axis
points directly toward the opposite wall.
6. Allow the laser unit to self-level, and mark and
measure points AA and BB on the walls as
shown in Figure 10.
7. Calculate the total error using the equation:
Total Error = (AA – A) – (BB – B)
8. Compare total error to the allowable limits
shown in the following table.
Distance between walls Allowable Error
L = 15 m (50
')
6 mm (0.25")
L = 25 m (80
')
10 mm (0.4")
L = 50 m (160
')
20 mm (0.8")
LEVEL CALIBRATION CHECK (Y-AXIS)
Repeat the procedure above, but with the laser unit
positioned so the Y-axis is pointed directly toward
the walls.
PLUMB ERROR CHECK (FIG. 11)
1. Using a standard plumb bob as a reference,
mark the top and bottom of a wall. (Be sure to
mark the wall and not the floor and ceiling.)
2. Position the rotary laser securely on the floor
approximately 1 m (3') from the wall.
3. Turn the laser on and level it using the arrow
buttons to center the bubble. Put the unit in low
speed rotation for maximum visibility, making
sure the beam passes through the mark on the
bottom of the wall. Recheck the bubble position
to confirm it is still centred.
