Using The Tool - YATO YT-09860 Manual Original

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 nec-
essary or make up for oil shortage in the lubricator. This will en-
sure the correct operation of the tool and extend its service life.
When using additional chucks or support racks, make sure that
the tool is correctly and securely attached.
Stand in a correct position to prevent normal or unexpected
movement of the tool due to torque.
The socket wrenches and other tools used must be suitable
for use with pneumatic tools. The tools to be inserted must be
effi cient, clean and undamaged and their size must be adapted
to the size of the carrier. It is forbidden to modify the wrench
or carrier sockets.
Pay attention to the working environment, the grinder can eas-
ily cut the nearby obstacles.
Do not use grinding wheels and tools intended for lateral grind-
ing for cutting.
Do not use cutting or milling wheels.
Self-locking abrasive wheels should be placed concentrically
on the grinder pad.
After switching off the grinder, wait until the rotating tool has
come to a complete standstill before setting it down.
Before installing any additional equipment, make sure that the
maximum equipment rotation speed is higher than that of the
grinder. Do not use equipment with chuck dimensions other
than that specifi ed in the manual. The tool to be inserted must
be fi rmly and securely attached to the tool chuck. 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 manufacturer 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 chucks for wear or damage.
Do not operate the grinder in a potentially explosive environ-
ment. 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 grinder. Any
irregularities must be rectifi ed before the next start of the grinder.
Make sure that the rotation speed of the grinder 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 protective equipment.
When selecting protective equipment, the type of material to be
treated must be taken into account.
Make sure that sparks and waste generated during operation
are not hazardous.
Wear personal protective equipment such as gloves, aprons
and helmets.
If the tool with the mounted grinding wheel is dropped, the con-
dition of the grinding wheel must be carefully examined before
switching the grinding wheel on again.

USING THE TOOL

Before each use of the tool, make sure that no parts of the
O R I G I N A L

pneumatic system are damaged. If you notice damage, imme-
diately replace the components with new, undamaged ones.
Dry the condensed moisture inside the tool, compressor and
hose before each use of the pneumatic system.
Installation of the working attachment (II)
Warning! Before disconnecting, installing and replacing a
working attachment, make sure that the drive housing is dis-
connected from the pneumatic system.
Pull the attachment locking ring towards the back of the housing
and hold it in this position. Push the selected working attachment
into the housing socket and release the locking ring. It should re-
turn automatically to its home position and block the possibility
of unintentional disassembly of the attachment. Ensure the as-
sembly has been correct. A correctly mounted attachment is in
line with the drive housing and can only be removed by pulling
and holding the locking ring. The connection of the drive housing
to the working attachment may have a slight working clearance
that does not aff ect the correct operation.
The housing socket is hexagonal, meaning that the attach-
ment can be mounted in six diff erent positions, allowing the
fi nal shape of the tool to be adapted to the conditions and er-
gonomics of the work.
Connecting the tool to the pneumatic system
The fi gure shows the recommended manner of connecting the
tool to the pneumatic system. This will ensure the most effi cient
use of the tool and also prolong the tool's service life.
Apply a few drops of SAE 10 viscous oil into the air inlet.
Screw a suitable nozzle to the air inlet thread fi rmly and se-
curely to connect the air supply hose. (III)
Secure a suitable nozzle to the tool driver. Only use acces-
sories which are suitable for use with impact tools when
working with pneumatic tools.
Connect the tool to the pneumatic system using a hose with an
internal diameter of 1/2". Make sure the hose has a durability
of at least 1.38 MPa. (IV)
Start the tool for a few seconds, making sure that there are no
strange sounds or vibrations.
Starting and stopping the tool
Caution! After each replacement of the working attachment, a
test run should be carried out without the tool to be inserted. Car-
ry out a test run for about 30 seconds, checking that the tool does
not show excessive vibration or increased noise. Before starting
the pneumatic tool, make sure that the carrier (tool chuck) does
not come into contact with any object or any body part.
The tool is operated by means of a lever which opens the air
valve and thus ensures the supply of compressed air to the
tool drive. The lever is equipped with a lock that prevents the
lever from being accidentally pressed. Turn the lock, so that it
is parallel to the lever, and then pull the lever towards the tool
housing. This will start the tool. Allow the tool to reach its rated
speed and only then start working.
The device is switched off by releasing the lever. The lever
automatically returns to the rest position and the lock secures
the lever. Please note that the tool to be inserted can still move
for some time after. Do not put the tool away until the tool to be
inserted has come to a complete standstill.
