1.General
1-1.In order to guarantee safety and best cutting
performance the operator must read and understand
and follow the instruction manual before operating.
1-2.All users must strictly follow the safety
instructions existing in the laws, decrees and
technical standards of their country and in machine/
blade instructions.
1-3.No one should attempt to operate any power
equipment unless they are familiar with its operation
and they have authorization to do so.
1-4.Students must have a full orientation and
must be supervised while operating any of the
machine tools.
1-5.Do not work with power machinery unless another
person is in the near vicinity.
2.Transport and storage
2.1. Diamond blades are easily damaged, must be
handled and transported with care.
2.2. Do remove the diamond blades from the machine
during transit to prevent accidental damage.
2.3 Diamond blades must be stored in dry conditions
in special racks or containers.
3.Correct selection of the
diamond blades
3.1. Follow any restriction of use and any specific
instruction which may be indicated on the diamond
blades or in the manual or in the manufacturer's
catalogue.
3.2.Ensure that the diamond blades are suitable
for the application and have the correct dimensions.
3.3. Check that the maximum RPM of the machine
spindle on which you will mount the diamond blades,
never exceeds the maximum RPM printed on the label
or on the product. The speed should be reduced
by 20-30% from the Max. RPM while cutting different
materials
3.4.Don't use your blade on metals or other unsuitable
materials.
4. Inspection and testing
before use
4.1.Check the machinery thoroughly before using
it, prior to starting it up.
4.2.Carefully inspect the blades, never use worn
or damaged blades
5.Mounting
5.1.Only mount the diamond blades on machines
designed for the operation.
5.2.The arrow indicating the direction of rotation
must be identical on the blades and on the machine.
5.3.Only mount the diamond blades with proper
flanges supplied with the handheld machine and
ensure they are clean and check both plates are
the same diameter. Flanges should never be modified.
The bore hole of the blade must fit the machine
spindle without play. Check blade nuts for tightness.
5.4. Don't force blade on blade shaft or mount
blade on undersized spindle.
6.Test-run
6.1.Before starting the test run check that the
machine is equipped with suitable guarding which
must be in the right position and locked. The
test-run of the diamond blades must be carried
out under no-load conditions for about 30 seconds
after each mounting.
7. Instructions for use
7.1.Before cutting:
7.1.1.Don't allow onlookers in the work area while
the saw is in operation.
7.1.2.Keep your fingers clear of all cutting tools
or moving devices.
7.1.3.Never use your bare hands to remove chips,
shavings, or other material from your work.Use
a brush or push stick.
7.1.5.Work pieces shall be firmly secured or clamped
before starting work.
7.1.6.Operators should stand away from and to
the side of the blade when in use.
7.1.7.Do ensure that the blade is in balance and
running true. A blade which is out of balance
means increased wear and even possible destruction
of the saw.
7.1.8.Do ensure that the machine bearings and
spindle are not worn otherwise blade life will
be reduced.
7.1.9.Do only use machines which have an approved
safety guard
7.1.10.Do inspect blades frequently to detect
cracks or undercutting of the steel core and segments
which could lead to segment loss.
7.1.11.Do tighten drive belts to ensure full available
power.
7.1.12.Do use drive pin if fitted to the machine.
7.1.13.Don't use paper washers to pack out the
clamp plates.
7.1.14.Don't operate machine with damaged or open
blade guard.
7.2. When cutting
7.2.1.Make a steady cut. Don't apply pressure
and force to your diamond blade through the cut,the
weight of the machine will sufficient . Increased
pressure means increased wear and overheat. Operate
engine at proper speed. Avoid hard contact and
knocks. Do use the blade with a gentle reciprocating
motion - especially when cutting hard materials,
and cut in the direction of the arrow. Never bend
the blade out of the line during cutting. Do avoid
tilting the blade when cutting in the material.
The cutting blade must not be used for curve or
circle cutting or grinding. Do ensure that the
blade cuts parallel to the wheel axis. The blades
must not be allowed to jam in the cut.
7.2.2.Ensure that the diamond blades do not get
too hot. If the blades get overheat, remove them
from the cut and allow to cool. Try to use water
as a coolant if it is available to prevent blade
over-heated, even it is marked dry cutting.
7.2.3.Don't adjust machine when it is running.
Never alter the rpm or governor setting. When
adjusting or installing or changing blade, disconnect
spark plug
7.2.4.If the blades become blunt,cut brick or
sandstone or abrasive wheel to re-sharpen.
7.2.5.For wet cutting,do ensure use correct amount
of water and adequate water supply to both sides
of the blade.
7.2.6.Do ensure that the machine is not dropped
on the blade.
7.2.7.Be careful to avoid burns from the overheated
segments or hot engine parts.
8. Grinding
8.1.1When using cup grinding wheels for rough
grinding, the grinding wheels should be positioned
towards the work piece surface maintaining an
angle of 5-10 degrees. In the case of finish grinding
the tool face should be held parallel to the work
piece.
8.2.Before commencing grinding, allow the grinding
wheel to run at operating speed for at least one
minute.
8.3.When commencing a grinding operation, bring
the object into contact with the grinding wheel
slowly and smoothly avoiding impact or bumping
motions.
8.4.Move back and forth across the face of the
object being ground as this prevents ruts or grooves
from forming.
8.5.Dress the wheel on the face only. Dressing
the sides may cause it to become too thin for
safe use. Do not press too hard on the wheel.
8.6.Vibrating wheels should not be used. They
must be dressed or replaced or the bearings of
the shaft replaced if they are worn.
9. Safety measures
9.1.Remove ties, rings, watches and other jewelry.
Long hair should be tied back and loose sleeves
should not be worn. Do not wear gloves when operating
a buffing, grinding or polishing wheel.
9.2.Make sure the wheel guards are in place and
properly adjusted and tightened.
9.3.Do not raise protective shield from around
blade when operating saw.
9.4.The operator must use personal protection
equipment such as safety glasses under a face
shield, leather gloves, masks ,protective goggles,
head cover and safety shoes.
9.5.Do not touch the work piece until you are
sure that it is cool.
9.6.Never leave machine unattended with the engine
running. Shut off engine when not in use, do not
leave until the wheel has come to a complete stop.
9.7.Stop the machine immediately if some odd noise
or vibration develops. Investigate the source
of the problem and do not operate the equipment
until the trouble has been corrected.
10. Pictograms
These pictograms may appear on posters, in brochures,
on packaging, on machines or on diamond blades
or their labels. Please require for it from the
seller if you do not find.
