2.2 Safety warnings common for grinding, sanding, wire brushing,
polishing or abrasive cutting-off operations:
▶
This power tool is intended to function as a grinder, sander, wire brush
or cut-off tool. Read all safety warnings, instructions, illustrations
and specifications provided with this power tool. Failure to follow all
instructions listed below may result in electric shock, fire and/or serious
injury.
▶
Operations such as polishing are not recommended to be performed
with this power tool. Operations for which the power tool was not
designed may create a hazard and cause personal injury.

Do not use accessories which are not specifically designed and
recommended by the tool manufacturer. Just because the accessory
can be attached to your power tool, it does not assure safe operation.

be within the capacity rating of your power tool. Incorrectly sized

accessory must fit the locating diameter of the flange. Accessories
that do not match the mounting hardware of the power tool will run out of

accessory such as abrasive wheels for chips and cracks, backing
pad for cracks, tear or excess wear, wire brush for loose or cracked

install an undamaged accessory. After inspecting and installing an
accessory, position yourself and bystanders away from the plane of
the rotating accessory and run the power tool at maximum no-load
speed for one minute. Damaged accessories will normally break apart
during this test time.
