Safety Warnings Specific For Wire Brushing Operations - Hilti AG 125-A22 Manual De Instrucciones

5.2.5 Additional safety instructions for sanding
operations
a) Do not use excessively oversized sanding disc
paper. Follow manufacturers recommenda-
tions, when selecting sanding paper. Larger
sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause
en
snagging, tearing of the disc or kickback.
5.2.6 Safety warnings specific for wire brushing
operations
a) Be aware that wire bristles are thrown by the
brush even during ordinary operation. Do not
overstress the wires by applying excessive load
to the brush. The wire bristles can easily penetrate
light clothing and/or skin.
b) If the use of a guard is recommended for wire
brushing, do not allow any interference of the
wire wheel or brush with the guard. Wire wheel
or brush may expand in diameter due to work
load and centrifugal forces.
5.3 Additional safety instructions

m) Adjust the pressure applied to the grinding or
cutting disc to suit the material you are working
on, so that the grinding or cutting disc doesn't
stall, possibly causing the tool to kick back.
n) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially
rotating insert tools, may lead to injury.
o) When grinding with straight grinding discs and
cutting with cutting discs in metalworking ap-
plications, use only the guard with cover plate.
This is available as an optional accessory.
p) Children must be instructed not to play with the
power tool.
q) The power tool is not intended for use by chil-
dren, by debilitated persons or those who have
received no instruction or training.
r) Do not use the power tool if it starts with a
jolt.This may be an indication that the electronic
control unit is defective. Have the tool repaired at
an authorized Hilti service center right away.
s) Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust
may cause allergic reactions and/or respiratory
diseases to the operator or bystanders. Certain
kinds of dust are classified as carcinogenic such
as oak and beech dust especially in conjunction
with additives for wood conditioning (chromate,
wood preservative). Material containing asbestos
must only be treated by specialists. Where the
use of a dust extraction device is possible it
shall be used. To achieve a high level of dust
collection, use a suitable vacuum cleaner of the
type recommended by Hilti for wood dust and/or
mineral dust together with this tool. Ensure that
the workplace is well ventilated. The use of a
dust mask of filter class P2 is recommended.
Follow national requirements for the materials
you want to work with.
5.3.2 Power tool use and care
a) Grinding discs must be stored and handled care-
fully in accordance with the manufacturer's in-
structions.
b) Check that the grinding disc is fitted in accord-
ance with the manufacturer's instructions.
c) If use of a spacer ring or other intermediate part
is specified and the part is supplied with the
grinding disc, check to ensure that the part is
fitted.
