DAMAGE AND/OR PERSONAL INJURY.
DANGER
PROPER OPERATIONAL USE OF A DIAMOND
BLADE THAT DOES NOT MEET INDUSTRY
SPECIFICATIONS AND/OR SAFETY
STANDARDS WITH THE CRACK SAW CAN
RESULT IN PROPERTY DAMAGE AND/OR
PERSONAL INJURY.
General Information.
1) " Only mature, properly instructed adults should
be permitted to operate machinery and tools.
2) Only utilize the blade to cut the material it is
designed and intended to cut. Blades intended for
masonry material (stone, concrete bricks, blocks) or
blades for steel or ductile iron must only be used in
those materials. If you need to cut a material other
than the ones listed above, you must use a blade
that has been designed for that specific material.
Use of a blade in the wrong material may involve a
considerable safety risk. It may also reduce the life
of the blade or damage the blade.
3) Inspect all diamond blades for damage before
use.
4) Never use a new or used diamond blade that
shows damage such as cracks, missing segments,
damage to the arbor hole or by the flange washers,
or other appearances not consistent with the
appearance of a new blade. These are indications of
previous improper use. If you have any doubt about
the safety of a blade, contact the Customer Service
Department of the blade manufacturer for
assistance. If you do not know the name of the blade
manufacturer, contact the Customer Service
Department of General Equipment Company for
assistance. There is no charge for this service.
5) Always check that the two mounting flanges are
of the same diameter and that they are clean and
flat. The flanges should not have any cracks or show
any abnormal wear. Make sure that the arbor bolt or
nut is the correct one for the equipment without
damage to the threads. Improper or damaged flange
washers and/or damaged fasteners can damage the
blade or cause the blade to come loose from its
mount. A blade that comes loose can cause serious
bodily injury or death to the operator or bystander. If
there are any questions regarding the suitability of a
specific mounting flange, contact the Customer
Service Department for assistance BEFORE utilizing
the diamond blade. There is no charge for this
service.
6) Always make sure that the arbor hole in the blade
matches the one on the equipment. Do not force the
blade onto the spindle. Do not use an arbor shaft
(spindle) and blade combination of different sizes.
Proper fit is achieved when the blade slides onto the
arbor without having more than 0.1 mm (0.005 inch)
radial play.
7) Always tighten the bolt or nut for the flange
washers in accordance with the equipment
manufacturer's specifications.
8) Always make sure that the equipment used is in
good operating condition in accordance with the
manufacturer's specifications. Do not operate the
equipment unless the guards are in good condition,
in the proper place and secure. If the equipment
appears to be missing any fasteners or has any
parts that appear loose or worn, do not operate the
equipment until the appropriate repairs are
performed. Always make sure the blade you intend
to use with the equipment meets all the equipment
manufacturer's specifications.
9) Do not operate the equipment with other than the
recommended blade sizes. This can result in severe
blade damage. Contact the machine manufacturer
for advice.
10) Make sure that the spindle speed on the
machine does not exceed the maximum RPM
indicated on the diamond blade. This can result in
blade breakage. Check the blade shaft with a
tachometer to verify that the equipment's maximum
RPM does not exceed the manufacturer's
specifications.
11) Blades designed for wet cutting must be cooled
by an adequate, continuous water flow to each side
of the blade. Lack of enough coolant will cause
excessive heat, poor blade performance and
possible segment loss.
12) Blades designed for dry cutting may be used
without water coolant. However, dry cutting blades
can overheat which will result in loss of blade
tension and may ruin the blade. The risk is greatest
during long continuous cutting. Most overheating
problems can be avoided by lifting the blade out of
