Safety Warnings common for Grinding
This power tool is to be used as a grinder. Observe all safety
warnings, instructions, illustrations and data supplied with
the power tool.
Non-observance of the following instruc-
tions can lead to electric shock, fire and/or serious injury.
This power tool is not suitable for sanding with sanding
sheets, working with wire brushes, polishing and cut-off
grinding.
Applications, for which the power tool is not
intended for, can lead to hazardous situations and 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.
The rated speed of the accessory must be at least equal to the
maximum speed marked on the power tool.
Accessories run-
ning faster than their rated speed can break and fly apart.
The outside diameter and the thickness of your accessory
must be within the capacity rating of your power tool.
Incorrectly sized accessories cannot be adequately
guarded or controlled.
Threaded mounting of accessories must match the grinder
spindle thread. For accessories mounted by flanges, the
arbour hole of the 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 balance,
vibrate excessively and may cause loss of control.
Do not use a damaged accessory. Before each use inspect
the accessory such as abrasive wheels for chips and
cracks, backing pad for cracks, tear or excess wear, wire
brush for loose or cracked wires. If power tool or accessory
is dropped, inspect for damage or 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 nor-
mally break apart during this test time.
Wear personal protective equipment. Depending on appli-
cation, use face shield, safety goggles or safety glasses. As
appropriate, wear dust mask, hearing protectors, gloves
and workshop apron capable of stopping small abrasive or
workpiece fragments.
The eye protection must be capable
of stopping flying debris generated by various operations.
The dust mask or respirator must be capable of filtrating
particles generated by your operation. Prolonged expo-
sure to high intensity noise may cause hearing loss.
