Cleaning and maintenance
‰
Before carrying out any work on the metal saw,
switch off the main motor switch.
‰ For safe working, always keep the machine
clean and ensure that the ventilation slots are un-
blocked.
Under extreme conditions, conductive
dust might enter the machine housing
when metal is cut. This might interfere
with the insulation of the saw. When cut-
ting metal under extreme conditions,
regularly blow out the ventilation slots.
The metal saw has been produced according to best
practice and extensively tested at the factory. In the un-
likely event of a failure, have it examined and repaired
by a Würthmaster-Service Workshop. In Germany, call
0800-WMASTER (0800-9 62 78 37) to contact the
Würthmaster Service. In Austria, call 0800-20 30 13.
In all your queries and spare part orders, always quote
the product number (see type plate) of your machine.
The current spare parts list of the machine can be
viewed online at http://www.wuerth.com/partsman-
ager. Alternatively, contact your local Würth agency
for a hardcopy.
Spare parts
Only use original spare parts. The use of parts from
suppliers other than WÜRTH might cause damage to
the equipment.
