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.

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.
