YATO YT-09717 Manual De Instrucciones página 13

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 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 protective 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.
Preparing the tool for operation
Screw a suitable nozzle to the air inlet thread fi rmly and
securely to connect the air supply hose (II).
Install the additional handle (III) to the housing using screws.
Before installing the blade, make sure that the permissible
rotation speed of the blade is equal to or higher than that of
the grinder.
Holding the spindle with one wrench, remove the blade fi xing
screw fi rmly and securely using the other wrench.
Mount the blade with the dimensions specifi ed in the technical
data table on the spindle.
Place the ring under the screw and screw it in. Holding the
spindle with one wrench, tighten the blade fi xing screw (IV)
fi rmly and securely using the other wrench.
Manually rotate the blade (several revolutions) to ensure that
the blade rotates smoothly and without jams.
The tool is ready to be connected to a pneumatic system.
Connecting the tool to the pneumatic system
The fi gure shows the recommended way to connect 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.
If the tool is equipped with a rotation reversing switch, set the
correct direction of rotation.

Wherever possible, adjust the pressure (torque).
Connect the tool to the pneumatic system using a hose with an
internal diameter of 10 mm / 3/8". Make sure the hose has a
durability of at least 1.38 MPa. (V)
Make sure that the inserted tool is not in contact with any
object, then run the tool for a few seconds to make sure that
no suspicious sounds or vibrations are coming from the tool.
Starting and stopping the tool
Caution! Before starting the pneumatic tool, make sure that
the mounted inserted tool 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. If 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.
Working with the cutter
Do not use the cutting blade for side grinding. Allow the blade
to run at full speed before starting to cut. Apply only the rotating
blade to the material. When cutting, apply only the same
pressure to the tool as is required for cutting the workpiece
Excessive pressure can damage the cutting blade, which
increases the risk of injury.
Securely clamp the workpiece to prevent accidental movement
during machining. The clamping should also ensure that the
gap created during the cutting process maintains the same
width or opens. When cutting large workpieces, a clamp or
support must be used on both sides of the cutting line. The
workpiece to be cut shall be supported near the cutting line and
the edge. This ensures that parts of the workpiece to be cut do
not collapse in such a way as to cause a jamming of the blade
when cutting.
During operation, sparks can form and fragments of the
workpiece can tear off . Make sure that sparks and loose parts
do not endanger the workplace.
MAINTENANCE
Never use petrol, solvent, or any other fl ammable liquid to clean
the tool. Vapours may ignite, causing the explosion of the tool
and serious injury.
The solvents used to clean the tool holder and the body may
soften the seals. Thoroughly dry the tool before starting work.
If you notice any malfunction of the tool, immediately disconnect
the tool from the pneumatic system.
All components of the pneumatic system shall be protected
against contamination. Contaminants entering the pneumatic
system can damage the tool and other components of the
pneumatic system.
Maintenance of the tool before each use
Disconnect the tool from the pneumatic system.
Before each use, introduce a small amount of preservative (e.g.
WD-40) through the air inlet.
Connect the tool to the pneumatic system and run it for approx.
30 seconds. This will allow you to spread the preservative
through the inside of the tool and clean it.
