•Check all electrical cables - be sure connections are tight and
cable is continuous and in good condition. Be sure cable is
correctly rated for both the operating current and voltage of
this equipment.
•Improperconnection oftheequipment-grounding conductorcan
result in a risk of electric shock. Check with qualified electri-
cian or service person if there is any doubt as to whether the
outlet is properly grounded. Adhere to all local codes and
ordinances.
• NOTE: In the event of a malfunction or breakdown, grounding
provides a path of least resistance for the electric current to
dissipate. The motor is equipped with a grounded plug and
must be connected to an outlet that is properly installed and
properly grounded. DO NOT modify the plug provided on the
motor. If the plug does not fit the outlet have a qualified electri-
cian install the proper receptacle.
•Switch motor OFF before disconnecting power.
•Engine exhaust from this product contains
chemicals known to the State of California to
cause cancer, birth defects or other reproduc-
tive harm.
•Gasoline is extremely flammable and poisonous.
It should only be dispensed in well ventilated areas,
and with a cool engine.
•Small gasoline engines produce high concentra-
tions of carbon monoxide (CO) example: a 5 HP 4 cycle
engine operation in an enclosed 100,000 cu. ft. area with
only one change of air per hour is capable of providing
deadly concentrations of CO in less than fifteen minutes.
Five changes of air in the same area will produce noxious
fumes in less than 30 minutes. Gasoline or propane pow-
ered equipment should not be used in enclosed or partially
enclosed areas. Symptoms of CO poisoning include, head-
ache, nausea, weakness, dizziness, visual problems and
loss of consciousness. If symptoms occur - get into fresh
air and seek medical attention immediately.

Safety Guidelines
Eye and ear protection must be worn at all times while the HSS-14 is in use. During normal opera-
tion, sound pressure levels exceed 85dBA. Use only ANSI approved safety glasses to help prevent
eye injury. Everyday eyeglasses have only impact resistant lenses; they are NOT safety glasses.
Operator must wear appropriate clothing and footwear. Do not wear loose clothing or jewelry that
can get tangled in moving parts. Footwear should provide sure footing and protection from debris
that may be dropped. Take steps to be sure hair will not be caught in moving parts. If necessary, tie it
back.
Disconnect the spark plug wire lead before performing any service on the machine.
• When loading or unloading the saw, use caution. Make sure rolling table is locked using the table lock so that the
blade will not be damaged. (Figure 4, Item K) Do not move the saw while the engine is running.
• This unit is shipped new from the factory without oil or gasoline, it will need to be added before it is used.
Check the Engine Manufacturer’s Owner’s Manual for instructions on break-in, servicing and use of engine.
This HSS-14 gasoline powered saw is designed to be used in areas where electrical power is not
available. Do not operate gasoline-powered equipment without adequate ventilation. The exhaust
fumes contain carbon monoxide, an invisible, odorless gas that can kill.
This machine is designed to cut brick, pavers, stone and tile. The work piece must be placed on the
rolling table surface and the table used to move the work piece to the blade. Cut only in a straight
line. Do not force or twist the work piece into the blade. Personal injury or damage to the equipment
or blade can result.
• Never exceed the maximum operating speed of the blade. Match the blade speed rating with the arbor shaft
speed.
• Never leave the saw running unattended.
•Never operate this saw under the influence of drugs, alcohol or when taking medications that impair the senses or
reactions, or when excessively tired or under stress.
• Make sure all safety decals can be clearly read and understood. Replace damaged or missing decals immedately.
Safety warnings and guidelines do not by themselves eliminate danger.
They are not given as substitutes for proper accident prevention procedures and good judgement.
Read and understand this Operator’s Instruction Manual,
and the Engine Manufacturer’s Owner’s Manual
before operating this equipment.
Death of serious injury can result if this machine is used improperly.

Before Starting Engine:
•Read and understand the instructions supplied by the engine manufacturer.
• Familiarize yourself with all engine and saw controls.
• Visually inspect the entire machine for damage or wear. Look for signs of oil or fuel leaks. Remove excess dirt or
debris. Check that all nuts, bolts and screws are tightened. Check for proper alignment of moving parts, possible
binding of moving parts, breakage of parts, loose mounting brackets, and any other condition that might affect op-
eration.
• Inspect diamond blade and arbor shaft. Check blades for cracks, loose segments, worn or out-of-round arbor holes.
Do not use warped, twisted, out-of-balance blades or any blade of questionable condition. (Figure 9)
• Check engine oil. Make sure that it is at the proper level and that it is clean.
Note: Some engines have an OilAlert System that will automatically stop the engine before the oil level falls below
the safe limit. To avoid an unexpected shut down, check the oil level regularly during operation.
• Check the fuel level. Do not over fill fuel tank and never refuel a hot engine. If refueling is necessary during opera-
tion, allow engine to cool down first.
•Inspect the air filter to be sure it is clean.
• If wet cutting, attach water source to the machine’s supply hose circled in (Figure 5). If you have a place for the
water to run, remove the drain plug in the water tray (Figure 6).
• If wet cutting with the optional water pump which recycles the water from the tray, plug the drain hole and be sure
the water is circulating from the tray to the water pump.
• If dry cutting, attach the vacuum to the end of the dust channel circled in (Figure 7).
Note: While the HSS-14 was designed to be used with a standard shop vac, EDCO recommends using a heavy
duty industrial vacuum such as the VAC-100. The VAC-100 has the advantage of a Self-Purging System to help
keep concrete dust from building up on the filter and a larger filter area to maintain performance during use. Thus,
reducing time wasted on frequently cleaning a standard shop vac and filter media.
Refer to the
Rx for Diamond Blades
for more detailed information
on diamond blades.

Starting the Engine:
• Be sure blade is clear of item to be cut.
• Determine that the recoil starter assembly turns freely, starter rope pulls easily, and the rope retracts properly.
• Follow the instructions supplied in the engine manufacturer’s Owner’s Manual for starting engine.
• Open the throttle and allow engine to reach operating temperature. Do not use the throttle as a means to match the
specified blade speed to the arbor shaft speed. Note: To ensure the necessary power is transferred to the blade, all
cutting must be done at full throttle. The governor is factory set for correct speed - altering this setting will damage
the machine. Maintain engine to factory specifications.
Cutting:
• Place the work piece on rolling table against the backstop and use the rolling table to move the work piece to the
blade. Do not strain the engine while cutting or jam work piece into the blade. Do not twist the work piece while
cutting.
• Do not reach underneath or around work piece while the blade is rotating.
• Keep stable footing at all times while cutting.
Keephair,clothing,fingers andallbodypartsaway fromthe blade
and any other moving parts.
• For wet cutting, maintain an adequate supply of water to cool the blade.
Note: If using the optional water pump, clean water must be run through
the cycle daily to avoid build up in the pump.
• When you have finished cutting, return throttle to idle. Stop the engine by
returning the engine mounted stop switch to the OFF position. Do not
leave the saw running unattended.
•Clean dust and debris from whole machine - including inside the dust channel.
IMPORTANT REMINDER: This machine is designed to use diamond blades to cut pavers, stone, tile,
masonry products and brick. Do not use it to cut anything else.

Step Three:
Look for “direction of rotation” markings on the new blade.
(Usually an arrow stamped on the blade.)
Place new blade on the arbor shaft verifying that the markings on the blade follow the
proper direction of rotation. Blade should be positioned in the center of the dust chan-
nel. (Figure 12)
Reinstall and tighten bolt using a SAE 3/4” wrench.
Reposition blade guard and tighten wing nuts.
Reconnect spark plug lead.
Figure 11
Changing the Blade:
• Inspect the new blade thoroughly before installing. Check for cracks, loose segments, worn or out-of-round arbor
holes. Refer to the Rx for Diamond Blades pamphlet provided with your blade for more detailed information on
inspecting blades. Besure the blade is appropriate for the job and matches the arbor shaft speed & mounting
configuration on this saw. (See page 11)
The HSS-14 was designed to be used with diamond saw blades only. It is a “fixed head machine”, therefore it is
important to use blades that will not wear down. Fiber blades will wear down and the cut will not go all the way
through the work piece. In addition, for the vacuum system to operate properly when dry cutting, the blade must
reach into the dust channel.
Step One:
Move the rolling table out of the way to the back or front
of the machine.
Loosen the two wing nuts on the back side of the blade
guard and rotate blade guard back and tighten to hold in
guard in place. (Figure 10)
Step Two:
Loosen and remove arbor cap bolt.
(Figure 11)
Carefully remove old blade.
Inspect arbor shaft, backing plate and
blade guard while blade is off.
Clean if dirty or replace if damaged or
worn.
Maintenance
Disconnect spark plug lead before performing
any maintenance on this machine.
Consult the Engine Manufacturer’s Owner’s Manual for more detailed engine maintenance instructions.

Belt Adjustment and Replacement:
• Periodically check to be sure the belts are undamaged and that they are at the proper tension. Slipping belts will
overheatcausing the cuttingspeed tobe limited andwill shortenthe life ofthe belts. Over-tensionedbelts will shorten
the life of the belts and bearings.
• On new equipment and after installing new belts, be certain to re-tension the belts after the first 4 hours of use.
New belts are stiff and require a break in period. Belts that become loose could slip and/or overheat.
• Damaged, stretched or excessively worn belts should be replaced with a new complete set of belts.
IMPORTANT: Belts must be replaced as a set, even if only one belt is showing wear.
• Remove belt guard (3 bolts) and inspect belts. A straight edge is a good tool to use to be certain sheaves are
even and properly aligned. (Figure 13)
• To tension/loosen belts or to remove worn belts, loosen engine mounting bolts (4) and slide the engine forward
or back until belts are at proper tension or loose enough to remove. (Figure 14)
• To remove belts, loosen engine mounting bolts (4) and jacking screw (circled) to allow the engine to slide
forward until belts slide off of the sheaves. (Figure 14)
• Place a complete set of new belts on the machine. Reposition engine then tighten bolts. Reinstall belt cover.
Clean and Lubricate Wheels on Rolling Table:
During daily visual inspection, check to be sure the wheels on the rolling
table move smoothly and that there is no debris in the wheel tracks.
(Figure 15)
Lubricate the wheels as necessary. Replace damaged or worn wheels
circled in (Figure 15).
