Metabo MFE 30 Original Instructions Manual page 16

ENGLISH
Ensure that the diamond cutting blades are
installed in accordance with the manufacturer's
instructions.
Prior to use, ensure that the diamond cutting
blades are properly fitted and secured. Run the
machine in idling for 60 seconds in a safe position
and bring to a standstill immediately if there are
significant vibrations or if other deficiencies are
determined. If such a situation occurs, check the
machine to determine the cause.
Never switch on the machine without the
protective cover installed.
The material being processed must be firmly
secured.
Ensure that sparks produced during work do not
constitute a risk to the user or other personnel and
are not able to ignite inflammable substances.
Endangered areas must be protected with flame-
resistant covers. Make sure that fire-risk areas are
always provided with suitable fire extinguishers.
When working in dusty conditions, ensure that
ventilation openings are not blocked. If it becomes
necessary to remove dust, first disconnect the
power tool from the mains supply (use non-
metallic objects) and avoid damaging internal
components.
The diamond cutting blades continue running after
the machine has been switched off.
5 Initial operation
Before plugging in check to see that the
rated mains voltage and power
frequency, as stated on the rating label,
match with your power supply.
