with RCD (residual-current device). An RCD
decreases the risk of electrical shock.
WARNING: High voltage. There are
unprotected parts in the power unit. Always
disconnect the power plug before you open
the door to the electrical box.
CAUTION: The power supply from
the product or generator must be sufficient
and constant to make sure that the motor
operates without problems. Incorrect voltage
causes the power consumption and the

influence the operation of other products, for
example flicker on the lights.
• The power plug must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce risk of electric
shock.
• Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
• Make sure that the power, fuse and mains voltage
are the same as the voltage shown on the rating
plate of the product.
• Always stop the product before you disconnect the
power plug.
• Make sure that the ON/OFF switch is in OFF position
