• To reset the bump sensor, press the button (2). The indicator (32) stops blinking and the tool returns to normal operation.

Tool aids (fig. I1 - I3)

Several aids have been supplied that might be helpful while operating the tool.

Laser enhancement glasses (fig. 11)

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.

Never look into the laser beam directly with these glasses.

DE0730 Target card (fig. I2)

The target card locates and marks the laser beam as the beam crosses the card, thus enhancing the visibility of the projected line. The laser beam passes through the red plastic surface and is reflected by the reflective rear side of the card. Supporting easy use during plumb and level adjustment, the card is marked with inch and metric scales, and has magnets at the top to hold it to ceiling track or steel studs.

Wall mount (fig. 13)

The wall mount may also be used as a base to provide extra stability for the tool.

Optional accessories

Consult your dealer for further information on the appropriate accessories.

These are:

• DE0732 Digital laser detector with clamp

Maintenance

Your DEWALT 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

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.

Tilt error checks

The following checks are performed to check the calibration of laser head for level alignment.

• Place the tool in an area midway between two vertical surfaces that are about 30 m away from each other.
• With the tool in a tripod set-up, adjust the head for a level application.
• To perform a quick check, read the front and rear air levels. After one of the air levels has been adjusted they should both be level. If the other air level is not level, the laser head must be calibrated.

To perform a front-to-back tilt error check:

• Position the tool so that it is aimed front-to-back toward the vertical surfaces.
• Switch on the tool with the laser head rotating.
• Mark the centre of the laser beam on each of the surfaces.
• Switch off the tool and rotate it 180^ so that it is aimed front to back the other way around.
• Switch on the tool with the laser head rotating and once again mark the centre of the laser beam on each of the surfaces. Switch off the tool.

• Measure the difference between the marks on both surfaces. The difference between the marks on the one surface must equal the difference between the marks on the other surface.

• If the difference between the marks is 6.35 mm or less, the laser head is properly calibrated.

• If the difference between the marks is more than 6.35 mm, the laser head must be calibrated.

To perform a side-to-side tilt error check:

• Position the tool so that it is aimed side-to-side toward the vertical surfaces.
• Following the same procedure as described above, mark the centre of the laser beam on each of the surfaces with the tool in this position, after which the tool is rotated 180^ to mark the centre of the laser beam once again.
• Measure the difference between the marks on both surfaces. The difference between the marks on the one surface must equal the difference between the marks on the other surface.
• If the difference between the marks is 6.35 mm or less, the laser head is properly calibrated.
• If the difference between the marks is more than 6.35 mm, the laser head must be calibrated.

Cone error check

The following check is performed to check the calibration of laser beam relative to the laser head.

• Place the tool in an area at about 7.5 m from a vertical surface.
• Adjust the head for a level application.
• To perform a quick check, switch on the tool with the laser head rotating. The tool should produce a single line. If the tool produces a double line, the laser head must be calibrated.
• Switch on the tool with the laser head stationary.
• Rotate the head so that the laser dots appear on the vertical surface.
• Mark the vertical position of the centre of each of the laser beams. Switch off the tool.
  • Measure the difference between the marks.
• If the difference between the marks is 2.4 mm or less, the laser head is properly calibrated.
• If the difference between the marks is more than 2.4 mm, the laser head must be calibrated.

Plumb error check

The following check is performed to check the calibration of laser head for plumb alignment.

- Place the tool in an area at about 7.5 m from a vertical surface.

• With the tool in a tripod set-up, adjust the head for a plumb application.
• Hang a plumb bob from the vertical surface.
• Switch the tool on with the laser head rotating.
• Align the laser line with the plumb bob string.
• If the laser line aligns with the plumb bob string, the laser head is properly calibrated.
• If the laser line does not align with the plumb bob string, the laser head must be calibrated.

Cleaning

• Remove the batteries 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.
