Care And Maintenance - Porter Cable RT-7690 Serie Guía Para El Usuario

16. Remove the Allen wrench from the calibration port. Turn on the power, turn
on the level laser beam, then check the height of the laser beam. Repeat
steps 14 and 15 until the beam is at the height of C.
# Caution: The Allen wrench must be removed from the calibration port before
turning on the power.
Calibration is complete.
17. Turn the power switch to the off position. Reattach the calibration port covers,
then resume normal operation.
! Note: Complete calibration of the level laser beam automatically calibrates
the plumb laser beam. Separate calibration of the plumb laser beam is not
required.

Care and Maintenance

The RT-7690 series laser systems are products of superior design and manufac-
ture, and should be treated with care. The following guidelines will help maintain
the products and fulfill warranty obligations:
• Keep the laser system, including parts and accessories, out of the reach of
small children.
• Do not store in dusty or dirty areas. Although the series RT-7690 laser sys-
tems are dust- and dirt-resistant, long-term exposure to these elements may
damage internal moving parts.
• Keep dry. The RT-7690 series laser systems are water-resistant; however,
precipitation, humidity, and liquids which contain minerals that corrode electri-
cal circuits may enter the units.
• Do not store in hot areas above 158°F (70°C). High temperatures can short-
en the life of electronic devices, damage batteries, and warp or melt certain
plastics.
• Do not store in cold areas below 14°F (-10°C). When the laser system
warms to normal operating temperature, moisture can form inside the base
unit and/or RF remote control/laser detector, where it may damage the circuit
boards.
• To avoid damage and personal harm, do not attempt to open the base unit
and/or RF remote control/laser detector. The units should be opened only by
qualified service personnel.
• Do not drop, knock, or shake the base unit and/or RF remote control/laser
detector. Rough handling impacts calibration accuracy.
• Periodically calibrate the base unit to ensure calibration accuracy.
• Do not use harsh chemicals, cleaning solvents, or strong detergents to clean
the base unit and/or RF remote control/laser detector. Wipe with a soft cloth,
slightly dampened in a mild soap-and-water solution.
• Keep the base unit laser aperture windows clean by periodically wiping them
with a lint-free swab moistened with isopropyl (rubbing) alcohol.
