DANGER
CAUTION
These safety alert symbols identify important safety messages in this manual. When you see these symbols, be
alert to the possibility of personal injury and carefully read the message that follows.
Do not allow anyone to operate the CRACK SAW without first reading this Operator Manual and becoming
familiar with its operation. The manufacturer of the CRACK SAW has gone to great extremes to provide the
owner(s) and/or operator(s) with the finest equipment available for its intended job function of removing covering
materials from concrete and wood floor surfaces. Yet, the possibility exists that the CRACK SAW can be utilized
in and/or subjected to job applications not perceived and/or anticipated by the manufacturer. Such misuse and/or
misapplication of the CRACK SAW can lead to the possibility of serious damage, injury or even death. It is the
responsibility of the owner(s) and/or operator(s) to determine that the CRACK SAW is being utilized and/or
operated within the scope of its intended job function. It is the responsibility of the owner(s) and/or operator(s) to
establish, monitor and constantly upgrade all safety programs and/or practices utilized in and for the operation of
the CRACK SAW. The purpose of such programs is to provide for owner(s') and/or operator(s') safety. Operators
must be instructed to recognize and avoid unsafe conditions associated with their work (29 CFR 1926.21 (b)(2))
and/or applicable updated revisions. It is the responsibility of the owner(s) and/or operator(s) to determine that no
modifications and/or alterations have been made to the CRACK SAW. Modifications and/or alterations can lead to
the possibility of serious damage, injury or even death. It is the responsibility of the owner(s) and/or operator(s) to

NOTICE TO OPERATORS
CAUTION
The concept of frame mounted type Crack Saws has been successfully utilized for many years as a
practical solution to many types of random crack sawing requirements. The basic concept is proven and
well accepted within the associated marketplaces. Use of a Crack Saw requires strenuous work activity.
This type of work activity can be considered to be greater in magnitude than that experienced with the
use of many other types of both light construction and lawn and garden related equipment. This type of
work activity should only be attempted by operators of adequate physical size and stature, mental
awareness and physical strength and condition. The body parts most noticeably affected during the
planing process are the arms, hands, wrists, shoulders, lower back and legs. The process can also
produce excessive stress/strain directly to the back muscles, spinal vertebrae and many other body
parts. Back related pain can be a side effect of utilizing a Crack Saw. An operator with a chronic back
related problem or a history of back and/or other medically related problems should not attempt to utilize
the Crack Saw. Use of the Crack Saw may only aggravate this and any other medically related problem.
Because of the diverse type of prevailing job applications, job site conditions, operator experience levels
and operator physical characteristics, no warranty, guarantee, representation and/or liability is made by
the manufacturer as to the absolute correctness or sufficiency of any operational procedure, operational
position and/or technique. There is no absolute guarantee that an operator of any given experience level,
physical size and/or physical condition will be immune to the possibility of and/or probable physical side
effects of the normal use of the Crack Saw. Each potential operator must be made aware of and assume
the operational and physical liability described and/or associated with the use of the Crack Saw. Improper
use of the Crack Saw can result in property damage and/or personal injury, including death. Each
potential operator not willing to assume the operational and physical liability described and/or associated
with the use of the Crack Saw, should not operate it. Proper levels of operator experience, skill and
common sense are essential for maximizing the safe and efficient operation of the Crack Saw.
Record the CRACK SAW and electric motor serial numbers in the spaces provided below.

SAFETY PRECAUTIONS
6) Prolonged use of the CRACK SAW (or other,
similar machines) exposes the operator to vibrations
which may produce Whitefinger Disease (Raynaud's
Phenomenon). This phenomenon reduces the
hand's ability to feel and regulate temperature,
produces numbness and burning sensations and
may cause nerve and circulation damage and tissue
necrosis. Antivibration systems do not guarantee
that you will not sustain Whitefinger Disease.
Therefore, continuous and regular users should
closely monitor the condition of their hands and
fingers. After each period of use, exercise to restore
normal blood circulation. If any of the symptoms
appear, seek medical advice immediately.
integrity. Replace each component as necessary.
The arbor shaft rotates at high speed during the
specific process and can be subject to high wear
rates if the installed diamond blade is not properly
maintained and/or replaced at regular service
intervals.
f) Determine that operator controls work freely, all
safety devices are operative and information decals
are readable.
g) Check to see that the Crack Saw and all related

danger of head injuries. Noise, generated by the
operation of the CRACK SAW and the actual
process itself, can damage your hearing. Wear
approved sound barriers (ear plugs or ear mufflers)
to protect your hearing. Continuous and regular
operators should have their hearing checked
regularly.
9) Contact appropriate representatives to determine
if/where electrical cables, gas lines and other
hazardous items are buried under the work surface
BEFORE utilization. The Crack Saw and related
accessories are not insulated. Contact with buried
electrical cables, gas lines and other hazardous
items can result in electrocution and/or an explosion.
10) Know how the controls operate. Know how to

INFORMATION RELATIVE TO THE USE OF
DIAMOND BLADES.
Safety requirements always override performance
considerations. Diamond blade technology has
made such rapid advances during the past few
years that a diamond blade, properly used, on well
designed and well maintained equipment, can
provide the lowest cost per cut of any of the
methods of cutting now in use. But, put that same
blade onto a piece of poorly maintained equipment
and in the hands of a poorly trained operator and the
cost of cutting can virtually put you out of business.
3) Using the funnel, fill the fuel tank with fresh, clean
fuel according to the specifications outlined in the
material supplied by the engine manufacturer. Do
not overfill the tank or spill any fuel. If the fuel tank
incorporates a screen mesh to prevent debris from
falling into the tank, do not remove to increase the fill
rate. Replace the filler cap. Wipe away any excess
spilled fuel.
DANGER
The members of the Saw Manufacturer's Institute
have been a significant contributor to the state of the
diamond blade art. We hope that some of the
knowledge and experience that we have
accumulated in our many years in the business can,
through this booklet, assist you in keeping your cost
down to an absolute minimum.

Of all the problems that confront diamond blade
users, blade wear is the most difficult to accurately
evaluate. Reporting life performance of identical
diamond blade specifications operating under
seemingly identical conditions tend to be
inconsistent.
Operation
THEORY OF OPERATION.
The RCC130H Crack Saw operates on the principle
of transmitting horsepower through
transmission directly to an industry standard, 8 inch
diameter, diamond segment blade of various widths.
a
V-Belt
Masonry blade operators frequently report blade life
in terms of hours, days or weeks. However, these
reports neglect to mention type of material being cut,
the size of the cuts, and the number of cuts per day.
In addition, the amount and the cleanliness of the
water and the amount of pressure the operator
applies to the cut have an effect on blade life.
The crack sawing process is directly controlled by
these conditions:
a) The use of a suitable mechanism (diamond blade)
of proper design and configuration to penetrate the
work surface and remove material while delivering
acceptable service life.
Obviously, trying to compare the life of one diamond
blade with another, simply on the basis of hours, is
analogous to trying to compare a set of tires on one
car with an identical set on another car...it is virtually
impossible. There are just too many variables...the
weight of the car, the types of roads driven on, the
condition of the car...particularly the suspension, the
manner in which the operator handles the car, etc.
Just as many variables apply to diamond blades.
b) Sufficient static weight supporting the diamond
blade to allow it to effectively penetrate the work
surface and remove material.
c) Adequate horsepower capable of rotating the
diamond blade at industry recognized speeds
against the work surface to deliver acceptable
productivity rates.
So, the next time you have reason to compare blade
life, keep these variables in mind. Some of the
problems arising from these variables can be quickly
identified, and possibly corrected"...
Since no two materials are exactly alike, no two
work surface materials can be sawed by the exact
same method. The nature of the sawing process,
along with operator experience, skill and common
sense, would suggest that efficient and productive
crack sawing is a matter of trial and error.

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)

General Information.
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.
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.
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.
3) Inspect all diamond blades for damage before
use.
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.
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.
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.
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
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

the cut and letting it cool by rotating in the air for 15
to 20 seconds after every one minute of cutting.
Nickel, Iron, Tungsten, Molybdenum, Tin, etc., as
outlined in the Material Safety Data Sheet (MSDS).
This product as sold presents no hazard although,
during use, small amounts of these metal
substances may be released into the dust or slurry
generated from the material being cut or ground.
Prolonged exposure to excessive amounts of dust
and slurry may cause respiratory disease, skin
irritation or cancer.
13) Do not force the tool into the material to be cut.
A properly working diamond tool will grind the
material without excessive force being applied. If
excessive force is needed, it indicates there is
damage to the blade to the blade or the wrong blade
is being used.
14) Always inspect the diamond blade and the
equipment any time you stop during the cut. If you
notice any difference in performance as your work
progresses, immediately STOP and inspect the
equipment and the diamond tool.
Common Sense.
Almost all accidents are avoidable if you apply
caution and common sense. Follow all safety
precautions at all times. If you are not sure...simply
don't do it. Ask for advice. Used improperly or
carelessly any tool is dangerous and may cause
severe bodily injury or death. If tools are used with
caution, proper techniques and common sense, they
will do an excellent job for you"...
15) Do not operate any diamond tool without full
knowledge about appropriate cooling of the tool. If a
tool is not cooled properly, the blade core can
become damaged resulting in the segments coming
loose or the blade core (the steel) breaking. This
can result in serious bodily injury or death to the
operator or bystander.
