Safety Guidelines
Eye and ear protection must be worn at all times while the GMS-14A is in use. During normal opera-
tion, sound pressure levels exceed 92dBA. 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. (Figure 4, Item W)
• When loading or unloading the saw, use caution. Make sure rolling table is locked so that the blade will not be
damaged. (Figure 3, Item O) 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 GMS-14A 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 interlocking pavers, retaining wall block and brick. 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.
(See page 9)
• 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 immediately.
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. (Figures 2-4)
• 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 operation.
• 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 8)
• Check engine oil. Make sure that it is at the proper level and that it is clean.
Note: Some engines have an Oil Alert 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 operation,
allow engine to cool down first.
•Inspect the air filter to be sure it is clean.
• If wet cutting, fill the water tray with water. The water pump 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 wet cutting, with an external source of water, such as a water barrel, open the drain plug in the water tray and make
sure the water has somewhere to go that is clear of the working area. One option is to hook up a second hose. (Figure
6)
• If dry cutting, attach a vacuum to the end of the optional dust lood. (Figure 7)
Note: While the GMS-14A was designed to be used with a standard shop vac, EDCO recommends using a heavy duty
vacuum such as the VAC-150. The VAC-150 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.

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.
Note: To ensure that 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 the engine according
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.
Keep hair, clothing, fingers and all body parts away from the 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 entire machine.
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.

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. Be sure the blade is appropriate for the job and matches the arbor speed and mounting
configuration on this saw. (See page 9)
The GMS-14A was designed to be used with diamond saw blades
Step One:
Remove spark plug lead from spark plug.
Pull the rolling table all the way to the front of the machine.
Adjust and lock the blade/blade guard assembly into a comfortable working position as
shown in (Figure 9).
Step Two:
Remove bolt and blade cap using a SAE
3/4” wrench (Figures 10 & 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.
Step Three:
Look for “direction of rotation” markings on the blade.
(Usually an arrow stamped on the blade.) Place new blade on
the arbor shaft verifying that once installed the markings on the
blade follow the proper direction of rotation. (Figure 13)
Reinstall blade cap and tighten bolt using a SAE 3/4” wrench.
If moved in step #1, reposition blade/blade guard assembly and
tighten. Reconnect spark plug lead.
Maintenance
Disconnect spark plug lead before performing
any maintenance on this machine.

Belt Adjustment and Replacement:
• Periodically check to be sure the belts are undamaged and that they are at the proper tension. Slipping belts will
overheat causing the cutting speed to be limited, shortening the life of the belts. Over-tensioned belts will shorten the
life of the belts & 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 14)
To tension belts, back off blade head assembly
bearing bolts(4) and slide the blade head assembly
forward or back until belts are at proper tension.
(Figure 15) NOTE: Be sure to align blade after belt
adjustment or belt replacement
To remove belts, back off bearing mounting bolts (4),
slide blade head assembly forward or backward
until belts slide off the sheaves.Place a complete
set of new belts on the machine. Realign blade
head assembly then tighten bolts.Reinstall belt cover.

Change Engine Oil:
• Check Engine Oil before each operation. Open the filler cap and look at the dip stick. (Figure 17) 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 Honda Cyclone Dual Filter style element.
Outer foam filter (Figure 19) 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 20)
Dirt build up on the filter will cause the engine to wear out faster.
