Ensure that no damage is caused to gas or water
pipes, electrical cables and weight-bearing walls
(statics).
When using the power tool outdoors, an FI safety
switch with a maximum tripping current of 30 mA
must be connected on the incoming line side.
Angle grinder in continuous operation: To avoid
the possibility of unintentional start-up: always turn
off the switch when the plug is removed from the
socket or if an interruption to the power supply has
occurred.
If operating the power tool in damp locations is
unavoidable, a Ground Fault Circuit Interrupter
must be used to supply the power to your tool.
Electrician´s rubber gloves and footwear will
further enhance your personal safety.
When using grinding wheel attachments, the
guard must always be attached to the tool and
positioned for maximum safety, so the least
amount of wheel is exposed from the side the tool
is being operated.
Grinding wheels or any other accessory must have
a maximum safe operation speed greater than the
"no load RPM" marked on the tool´s nameplate.
Always use auxiliary handle for maximum
control over torque reaction or kick-back.
Operation of the grinder without the side handle
could cause loss of control of the grinder, resulting
in possible serious personal injury.
Before using a grinder or installing a new
wheel, inspect the grinding wheel for chips and
cracks. Remove bad wheels immediately. Run
the tool at no load for one minute, holding the
tool in the direction away from people. Wheels
with flaws will normaly break apart during this time.
Carefully handle both the tool and individual
grinding wheels to avoid chipping or cracking.
Install a new wheel if tool is dropped while
grinding. Do not use a wheel that may be
damaged. Fragments from a wheel that bursts
during operation will fly away at great velocity
possibly striking you or bystanders.
Warning! Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
– Lead from lead-based paints,
– Crystalline silica from bricks and cement and
other masonry products, and
– Arsenic and cromium from chemically treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as dust masks that are specially
designed to filter out microscopic particles.
