d)Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers during breaks between working.
e)Always lead the supply cord and extension cord away from the power tool to the rear while working. This helps to avoid tripping over the cord while working.
f)Children must be instructed not to play with the appliance.
g)The appliance is not intended for use by chil- dren, by debilitated persons or those who have received no instruction or training.
h)WARNING: Some dust created by grinding, sand- ing, cutting and drilling contains chemicals known to cause cancer, birth defects, infertil- ity or other reproductive harm; or serious and permanent respiratory or other injury. Some ex- amples of these chemicals are: lead from lead- based paints, crystalline silica from bricks, con- crete and other masonry products and natural stone, arsenic and chromium from chemically- treated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce exposure to these chemi- cals, the operator and bystanders should work in a
5.2.3Power tool use and care
a)Check that the insert tools used are compatible with the chuck system and that they are secured in the chuck correctly.
b)In case of an interruption in the electric supply: Switch the power tool off and unplug the supply cord. This will prevent accidental restarting when the electric power returns.
c)Always work from a secure, safe stance.
5.2.4Electrical safety
a)Before beginning work, check the working area (e.g. using a metal detector) to ensure that no concealed electric cables or gas and water pipes are present. External metal parts of the power tool may become live, for example, when an electric cable is damaged accidentally. This presents a serious risk of electric shock.
b)Check the power tool’s supply cord at regular intervals and have it replaced by a qualified spe- cialist if found to be damaged. If the power tool’s supply cord is damaged it must be replaced with a
c)Dirty or dusty power tools which have been used frequently for work on conductive materi- als should be checked at regular intervals at a Hilti Service Center. Under unfavorable circum- stances, dampness or dust adhering to the surface of the power tool, especially dust from conductive materials, may present a risk of electric shock.
d)When working outdoors with an electric tool check to ensure that the tool is connected to the electric supply by way of a ground fault circuit interrupter (GFCI) with a rating of max. 30 mA (tripping current). Use of a ground fault circuit interrupter reduces the risk of electric shock.
e)Use of a ground fault circuit interrupter (GFCI) with a maximum tripping current of 30 mA is recommended.
5.2.5Work area
a)Ensure that the workplace is well lit.
