NOTE: Servicing of a product with double insulation
requires extreme care and knowledge of the system and
should be performed only by a qualifi ed service technician.
For service, we suggest you return the product to your
nearest authorized service center for repair. Always use
original factory replacement parts when servicing.
ELECTRICAL CONNECTION
The product has a precision-built electric motor. It should
be connected to a power supply that is 230 volts, AC only
(normal household current), 50 Hz. Do not operate the
product on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If
the product does not operate when plugged into an outlet,
double-check the power supply.
EXTENSION CORDS
When using a power tool at a considerable distance from
a power source, be sure to use an extension cord that has
the capacity to handle the current the product will draw. An
undersized cord will cause a drop in line voltage, resulting
in overheating and loss of power.
When working outdoors with a product, use an extension
cord that is designed for outside use.
Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains
chemicals known to cause cancer, birth defects or other
harm. Some examples of these chemicals are:
lead from lead-based paints
crystalline silica from bricks and cement and
other masonry products, and
arsenic and chromium from chemically-treated
lumber
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals, work in a well ventilated
area, and work with approved safety equipment, such
as dust masks that are specially designed to fi lter out
microscopic particles.
