DANGER
IMPROPER USE OF A DIAMOND BLADE WITH 
THE CRACK SAW CAN RESULT IN PROPERTY 
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
