•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).

Change Engine Oil:

• Check Engine Oil before each operation. Open the ﬁller cap and look at the dip stick. (Figure 16)

Oil should be clearly visable both on the stick and in the cavity and should look fairly clean. Running the machine

on dirty oil or when the oil is low will result in damage to the equipment.

• Change the Engine Oil after every 50 hours of operation - or sooner as conditions require. Refer to the Engine

Manufacturer’s Owner’s Manual for speciﬁc viscosity recommendations and changing instructions.

Inspect and Clean Oil Air Filter:

Shown with ﬁlter element. Outer foam ﬁlter is removable for cleaning. Refer to the Engine Manufacturer’s Owner’s

Manual for instructions on speciﬁc models. Check air ﬁlter at least once daily. (Figure 17)

Dirt build up on the ﬁlter will cause the engine to wear faster.

Grinding/cutting/drilling of masonry, concrete, metal and other materials can generate dust, mists and fumes containing

chemicals known to cause serious or fatal injury or illness, such as respiratory disease, cancer, birth defects or other

reproductive harm. If you are unfamiliar with the risks associated with the particular process and/or material being

cut or the composition of the tool being used, review the material safety data sheets and/or consult your employer,

the manufacturers/suppliers, governmental agencies such as OSHA and NIOSH and other sources on hazardous

materials. California and some other authorities, for instance, have published lists of substances known to cause

cancer, reproductive toxicity, or other harmful effects.

Control dust, mist and fumes at the source where possible. In this regard use good work practices and follow the recom-

mendations of the manufacturers/suppliers, OSHA/NIOSH, and occupational and trade associations. Water should

beused for dustsuppression when wetgrinding/cutting/drilling is feasible. Whenthe hazards frominhalationof dust,

mists and fumes cannot be eliminated, the operator and any bystanders should always wear a respirator approved

by NIOSH/MSHA for the material being used.

Grinding/cutting/drilling of masonry, concrete and other materials with silica in their composition may give off dust or

mists containing crystalline silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous

other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or

fatalrespiratorydiseases, including silicosis. Inaddition, California and someother authorities have listedrespirable

crystalline silica as a substance known to cause cancer. When grinding/cutting/drilling such materials, always follow

the respiratory precautions mentioned above.
