Electric safety recommendations
• The tool plug should always be inserted to an appro-
priate socket. This reduces the risk of electric shock.
Do not use plug adapters with grounding contacts.
• Avoid touching grounded items, such as metal pipes,
heaters, cookers and refrigerators. If the worker's body
comes into contact with a grounded item, the danger of
electric shock increases.
• Protect the power tool against rain and moisture.
Penetration of water into the tool increases the danger
of electric shock.
• Do not use the power supply cable for purposes
other than designed. Under no circumstances should
one use the cable to carry the tool or pull it; also, it is
forbidden to switch off the tool by pulling the power
supply cable. Protect the cable against heating,
contact with kerosene-based bodies, with sharp
edges or mobile parts of the tool. A power cable that
is damaged or spliced increases the danger of electric
shock.
• When working in open air, use extension cords
designed for this type of work, which will reduce the
danger of electric shock.
Personal protection recommendations
• Be cautious when working with power tools, and
carefully plan your actions. Do not use the tool when
fatigued, or under the influence of drugs, alcohol or
medicines. Careless handling may result in serious
injuries.
• Use personal protection equipment. Always wear
protective goggles. When necessary, use respirators,
non-slipping boots, hard hats and earplugs. The use
of personal protection equipment is one of the factors
that reduce the risk of injuries.
• Avoid incidental activation of power tools. Before
inserting the plug, make sure that the power switch is in
OFF position. When carrying the tool, take your fingers
off the main switch, which will reduce the possibility of
incidental activation.
• Before switching on the tool, remove any wrenches
and other objects from its rotating parts. A wrench left
in the rotating unit may result in serious injuries.
• Do not apply excessive force, take a stable position
and always try to keep balance - this will facilitate
control over the tool.
• Do not wear loose clothes or freely-hanging jewel -
lery. Hair, parts of garment and gloves should be pro -
tected against contact with moving parts of the power
tool.
• If the tool is equipped with a dust collection device,
make sure that the device has been activated and
used properly. Use of such devices helps reduce the
concentration of dust at the workstation.
Use and handling of power tools
• The persons with lowered psychophysical or mental
aptitudes as well as children can not operate the power
tool, if they are not supervised or instructed about use
of the power tool by a person responsible for their
safety.
• Do not overload the tool. Power tools are to be used
only in operations, to which they have been designed,
which will ensure safety and help achieve better
results.
• Do not use power tools with a damaged power
switch. A tool that cannot be switched on and off in a
controlled manner is potentially dangerous and must
be repaired immediately.
• Before adjustment operations, replacement of
attachments, and during storage, remove the power
tool plug from the mains socket. This eliminates the
risk of the tool being unintentionally activated.
• The tool should be stored out of children's reach.
Do not allow the use of power tools by persons who
have not read this manual and are inexperienced. In
the hands of an inexpert person, the tool may be dan -
gerous both for the operator and his environment.
• Take proper care of the tool condition. Monitor the
axial run-out and stability of movable parts' joints, and
pay proper attention at any faults that may result in the
tool damage. Bad condition of power tools is a frequent
cause of accidents.
• Cutting tools should be kept clean and must be well-
sharpened. Cutting tools with sharp cutting edges,
which are properly fixed reduce the risk of seizure and
facilitate the control over power tools.
• When using power tools and its accessories, follow
the instructions listed in this manual. During work with a
specific type of power tools, follow recommendations,
taking into account operational conditions and the type
of job performed.
Service of power tools
Your power tool should be serviced only by qualified
specialists, with the use of recommended spare parts.
This will guarantee labour safety, when your tool is
being applied.
Safety guidelines during
power tool operation
Before commencing operation
• It is obligatory to switch on a power tool to the socket
that is properly grounded by grounding contact.
• Use grinding discs safe rotation ratio of which is
bigger than rotation ratio of spindle of power tool.
Follow manufacturers' recommendations regarding
use of tools and accessories.
• Do not use grinding discs that have cracks, cleav -
ages, distortions, as well as grinding discs causing in-
creased vibration of power tool.
• Protect grinding discs from shock, prevent them
from greasing.
• Do not use grinding discs dimensions of which
(outer diameter and bore diameter) differ from the
recommended ones.
• Never work with protection devices dismounted.
Damaged protection devices must be replaced
immediately.
During operation
• Apply the workpiece to the grinding disc only when
the disc reaches its maximum rotation speed.
• Do not use the side surface of grinding disc for
grinding.
• Do not stop the motor of power tool when it is en-
ergized.
• Beware of recoil (sudden push back) of the workpiece
while operating the power tool. Recoil can be caused
