ORIGINAL INSTRUCTIONS
used to prevent damage to the connections between the hoses and be-
tween the hose and the tool. Do not exceed the maximum air pressure
specifi ed for the tool. Never carry the tool holding it by the hose.
Caution! Tool kickback towards the operator
The kickback of the tool towards the operator is caused by a sudden reac-
tion to a locked or clamped grinding wheel or other accessory. Locking or
clamping causes a rotating accessory to stop suddenly, which results in the
pneumatic tool rotating in the opposite direction to the accessory rotation.
For example, if the grinding wheel is locked or clamped by the workpiece,
the edge of the grinding wheel which reaches the clamping point can sink in
the surface of the material, causing the grinding wheel to escape or be eject-
ed. The grinding wheel can also escape towards or away from the operator,
depending on the direction of the grinding wheel movement at the clamping
point. The grinding wheels may also break in such conditions. The tool kick-
back towards the operator is a result of misuse and/or failure to follow the
guidelines in the User Manual. This occurrence can be avoided by following
the instructions below. Use a fi rm grip on the tool and the correct position
of the body and hands to withstand the forces generated by the kickback.
Always use an additional handle, if supplied with the tool, to ensure maxi-
mum control during the kickback or any unexpected rotation during the tool
start. The operator will be able to control the tool rotation or the kickback if
appropriate precautions are taken. Keep your hands away from rotating tool
parts. The rotating parts can come into contact with your hands, when kicked
back. Do not stand in the area where the tool may kick back. The kickback will
direct the tool in the opposite direction to the direction of the grinding wheel
rotation, at the clamping point. Pay special attention when working near cor-
ners, sharp edges, etc. Prevent the grinding wheel from jumping and being
jammed. When working corners or edges, there is an increased risk of the
grinding wheel jam, leading to a loss of control over the tool or its kickback.
Do not use cutting chain blades or circular saws. The blades cause frequent
kickbacks and the loss of control of the tool.
Warnings related to grinding and cutting with grinding wheels
Use only tool-specifi c grinding wheels and guards that are designed for the
type of the grinding wheel in question.
The grinding wheels for which the tool is not designed cannot be properly
guarded and are not safe.
The guard must be securely attached to the tool and positioned for max-
imum safety so that the smallest possible area of the wheel is exposed
towards the operator. This guard helps to protect the operator from broken
wheel fragments and prevents accidental contact with the grinding wheel.
The grinding wheel must be used as intended. For example, do not sand
with a cutting grinding wheel. Cutting grinding wheels are designed for use
under heavy pressure and the lateral forces applied to them may cause
them to fall apart.
Always use undamaged fi xing fl anges that are the correct size for the grind-
ing wheel. The correct fi xing fl anges reduce the risk of damage to the grind-
ing wheel. The fi xing fl anges for cutting grinding wheels can be diff erent
from the fi xing fl anges for grinding wheels.
Do not use worn grinding wheels from larger tools. A larger diameter grind-
ing wheel is not suited for
higher rotation speed of smaller tools and may break.
OPERATING CONDITIONS
Make sure that the compressed air source generates the correct working
pressure and provides the required airfl ow. If the supply air pressure is too
high, a pressure reducer with a safety valve must be used. The pneumatic
tool must be fed through the fi lter and lubricator system. This will ensure that
the air is both clean and moistened with oil. Check the condition of the fi lter
and lubricator before each use and clean the fi lter if necessary or make up for
oil shortage in the lubricator. This will ensure the correct operation of the tool
and extend its service life.
Always use the tool with the additional handle fi tted. The additional handle
allows safer and more effi cient work.
When using additional holders or support racks, make sure that the tool is
correctly and securely attached.
Fix the workpiece in such a way that the gap created during cutting main-
tains the same width or opens.
Stand in a correct position to prevent normal or unexpected movement of
the tool due to torque. If the cutting wheel gets stuck in the workpiece,
switch it off in order to release the blade. Make sure that the blade is not
damaged before switching the tool on again.
Pay attention to the working environment, the cutter can easily cut the near-
by obstacles.
Do not use the grinding wheels and the cutting tools for lateral grinding.
After switching off the cutter, wait until the rotating tool has come to a com-
plete standstill before setting it down.
Before installing any additional equipment, make sure that the maximum
equipment rotation speed is higher than that of the cutter. Do not use equip-
ment with a handle diameter other than that specifi ed in the manual. The
accessory equipment must be fi rmly and securely attached to the tool hold-
er. Do not use sleeves or reduction rings to adjust the spindle diameter of
the tool and the grinding wheel.
Store and use the grinding component according to the equipment manu-
facturer instructions. Do not use damaged equipment. Equipment with any
defects must be immediately replaced with new, functional one. Check the
condition of the spindle and tool holders for wear or damage.
Do not operate the cutter in a potentially explosive environment. Sparks
generated during operation may cause fi re.
After mounting the wheel, switch the tool on for approx. 30 seconds in a
safe position. Stop the machine immediately if you notice high vibrations
or other defects in the functioning of the cutter. Any irregularities must be
rectifi ed before the next start of the tool.
Make sure that the rotation speed of the tool is not greater than the speed
indicated on the nameplate.
Some materials may produce poisonous or combustible dusts and vapours
during machining. Work in well-ventilated areas and use personal protec-
tive equipment.
Make sure that sparks and waste generated during operation are not hazardous.
Wear personal protective equipment such as gloves, aprons and helmets.
Hearing protection must also be used.
If the tool with the mounted grinding wheel is dropped, the condition of the
grinding wheel must be carefully examined before switching the grinding
wheel on again.
TOOL USE
Before each use of the tool, make sure that no parts of the pneumatic system
are damaged. If you notice damage, immediately replace the components with
new, undamaged ones.
Dry condensed moisture inside the tool, compressor and hose before each
use of the pneumatic system.
