1.1 INTRODUCTION
Your RS17 Ring Saw has been engineered to provide sawing performance, long term economics and safety advantages
that no other type can match. However, even a well-designed and well-built saw can malfunction or become hazardous in
the hands of an inexperienced and/or untrained user. Therefore, read this manual and related equipment manuals
thoroughly before operating your saw to provide maximum safety for all operating personnel, and to get the maximum
benefit from your equipment.
1.2 SAFETY DEFINITIONS
A safety message alerts you to potential hazards which could injure you or others or cause property damage. The safety
messages or signal words for product safety signs are DANGER, WARNING, and CAUTION. Each safety message is
preceded by a safety alert symbol and is defined as follows:
DANGER: Indicates an imminently hazardous situation which, if not avoided, will cause death or serious injury. This
safety message is limited to the most extreme situations.
WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It
may also be used to alert against unsafe practices that may result in property-damage-only accidents.
1.3 POWER SOURCE AND SAW SAFETY LABELS
These labels warn you of potential hazards which could cause injury. Read them carefully. If a label comes off or
becomes illegible, contact the dealer for a replacement.
1.4 RS17 RING SAW SAFETY RULES
1. Only trained personnel shall operate the saw or perform repairs. A trained person is one who has read and thoroughly
understands this instruction manual and related equipment manuals and, through training and experience, has shown
knowledge regarding the safe operational procedures.
2. Sawing area must be kept clear of unauthorized personnel at all times. Place barricades or secure the area with signs
and a roped boundary to prevent personnel injury.
3. Never use the saw in an explosive atmosphere and/or near combustible material that could be ignited by a spark.
4. Do not use a saw that shows any signs of damage. Do not use the saw if the blade does not stop rotating when the
power-activating trigger lever is released.
5. The guard provides protection against contact with moving parts, ejected debris, and during wet cutting operations,
thrown water and concrete slurry. Adjust the blade guard for the cut being made. Never run the saw without the
blade guard in place.
6. Never allow anyone to stand in front of, or in line with, the blade forward of the guard.
7. Always use blades that meet applicable safety code specifications. Read and comply with blade manufacturer’s
instructions and safety precautions provided with the blade. Destroy any blade with cracks, chips, gouges, or loose or
missing tips.
8. Always use safety footwear, safety goggles or face shields, and hearing and head protection devices. Safety shoes
MUST provide good footing to prevent slipping or falling down. Gloves protect the hands from chips and should be
worn. During dry cutting operations, provide also adequate ventilation or approved NIOSH or MSHA respirators in
closed areas to avoid breathing dust. During wet cutting operations, use also a snug fitting wet suit.
9. Do not use the saw when you are tired or fatigued.

2
10. Never operate the saw under the influence of drugs, alcohol, or medication.
11. Always carry the saw in its de-energized state.
12. Keep the saw handles dry, clean, and free of oil or fuel.
13. This saw is not insulated. Do not start cutting without first de-energizing electrical wiring near the cutting site or
imbedded in any concrete.
14. Prior to cutting, plan your cuts to prevent pinching of the blade or personnel injury from falling material.
15. Always hold the saw with both hands during operation. Use a firm grip on the handles.
16. Never exceed the flow and pressure rating of the saw which is 12 gpm at 2500 psi.
17. Do not exceed either the blade maximum operating speed of 3240 rpm or the blade manufacturer’s rated speed.
18. Do NOT attempt to adjust the saw during operation.
19. Keep clothing and all parts of the body away from moving parts of this saw when connected to a power source or
being used.
20. Any slurry formed during wet cutting operations is very slick. Remove while still wet to prevent yourself or others
from slipping while cutting. Slurry that has been allowed to dry is very difficult to remove.
21. Always shut off the hydraulic power and cooling water sources before disconnecting the hoses or servicing the saw.

3OPERATION
Follow all the safety procedures in Chapter 1 of this manual and in the manual supplied with your hydraulic power unit.
Failure to do this can cause equipment damage and/or personal injury. Make sure you are wearing all your safety
equipment including approved NIOSH or MSHA respirators during dry cutting or a wet suit during wet cutting.
3.1 COMPONENT PRE-START CHECKS
The following components must be checked before you can use the saw safely. Running the saw with an undetected defect
in either of these components will quickly cause equipment damage.
•Hydraulic system
•Drive Wheel and Blade
3.1.1 Hydraulic System
1. Before making any hydraulic connections, inspect all hoses for leaks and risks of rupture as follows:
a. Inspect each hose for breaks, cracks, worn spots, bulges, chemical attack, kinks or any other damage. Never stop
any detected leak with your hand or fingers. Do not put your face close to suspected leaks. Hold a piece of
cardboard close to suspected leaks and then inspect the cardboard for signs of hydraulic oil.
b. Replace a damaged hose immediately. Never repair the hose.
2. CONNECTING HYDRAULIC HOSES
•Wipe all hose couplers with a clean lint free cloth before making connections. Do not connect pressure to the return port.
•Connect the return (tank) line from the saw return port to the hydraulic power source return port. Then connect
the pressure line from the saw pressure port to the hydraulic power source pressure port.
•Make sure the hydraulic hoses are connected properly and fully seated to ensure that the flow is in the proper direction.
•Pressure relief valve must not exceed 2500 psi @ 12 gpm. The pressure relief valve must be located in the
supply circuit between the power supply and tool to limit excessive hydraulic pressure to the tool.
•Note: If uncoupled hoses are left in the sun, pressure increase inside the hoses might make them difficult to
connect. Whenever possible, connect the free ends of the hoses together when not in use.
WARNING:
COVER THE FITTING END WITH A RAG TO REDUCE THE RISK OF BEING SPRAYED
WITH HYDRAULIC FLUID. ESCAPING FLUID UNDER PRESSURE CAN PENETRATE THE
SKIN AND CAUSE SERIOUS PERSONAL INJURY. IF INJURY OCCURS, GET IMMEDIATE
MEDICAL ATTENTION.
3.1.2 Drive Wheel and Blade
1. Inspect the drive wheel and mounting flange for gouges, hairline cracks, and wear. Replace these immediately if any
of these conditions are present as described in Chapter 4.
2. Be sure the drive wheel & mounting flange are clean and straight so blade will run true in “V” slot.
3. Be sure the drive wheel & mounting flange are tightened securely.
4. Always use the blade recommended by the blade manufacturer for your application.

7
5. Inspect the blade for cracks, chips, gouges, or loose or missing tips. Destroy the blade if any of these conditions are
present.
6. Ensure a blade is installed to blade manufacturer’s specified direction of rotation. Saw rotation is clockwise as
viewed from the guide roller side of the saw.
7. Check that Blade can be turned by hand, before saw is connected to hydraulics.
3.2 STARTING THE SYSTEM
1. This saw is not insulated. Do not start cutting without first checking for live electrical wiring near the cutting site, or
imbedded in the cutting medium. If power lines are unavoidable, consult power company before starting operation.
2. The following precautions must be observed when lifting the saw:
a. Be sure of your footing.
b. Keep hands off trigger to avoid accidental operation.
c. Bend your knees and lift with your legs.
d. Hold saw close to your body when lifting.
3. Ensure the power supply is turned off.
WARNING:
THE GUARD PROVIDES PROTECTION AGAINST CONTACT WITH MOVING PARTS,
EJECTED DEBRIS, AND DURING WET CUTTING OPERATIONS, THROWN WATER AND
CONCRETE SLURRY. NEVER RUN THE SAW WITHOUT THE BLADE GUARD IN PLACE.
4. Always check the gpm and psi rating of both the saw and the power drive before using to prevent equipment damage.
Do not exceed the maximum hydraulic flow rate and pressure of 12 gpm (45 lpm) and 2500 psi (172 bar).
Overspeeding the blade can cause equipment damage and possible personal injury.
5. Check that the pressure and return hoses are connected properly to the saw and power source ports as described in
Section 3.1.1.
6. Before starting your power supply, read and fully understand the operating manual provided.
7. Use caution when handling fuel for a gasoline engine driven hydraulic power source unit. Move the hydraulic power
source at least 10 feet from the fueling point before starting the engine. Make sure the gas caps on the hydraulic
power source and fuel can are properly tightened.
3.3 CUTTING PROCEDURE
1. Connect water supply.
2. Set power source to “ON”.
3. Open water supply.
4. Provide rigid support and “hold down” of piece being cut—both sides of the cut, if practical.
5. Grasp the auxiliary handle with your left hand. Use the appropriate part of the handle for making vertical or
horizontal cuts.

8
6. Grasp the trigger with your right hand.
7. Position the saw in the appropriate place to make the desired cut.
8. Depress (squeeze) the trigger to start the saw. Never exceed either the blade maximum operating speed of 3240 rpm
or the blade manufacturer’s rated speed.
9. Feed the rotating blade into the work surface using a straight, steady, constant pressure. Do NOT “bump,” jam or
force the blade into the work surface, or twist the blade in the cut. This can cause equipment damage.
10. Start by holding the blade towards the material. When gradually a groove is cut, press the blade towards the material and cut
in lines of 2-3 inches until you have cut through the material. This is the quickest way of cutting instead of cutting through in one
attempt.
11. It is important to keep the water supply steady and sufficient as it cools the blade, removes the slurry and guarantees you the
best result with as little wear on the blade and rollers as possible.
Stop
•Remove the blade from the material and let go of the trigger lever
•Set the power source on “OFF”
•Disconnect water supply
Note: For easier cleaning let the blade spin in the air with full water running for 30 seconds. It will help removing slurry
from blade and rollers. RGC recommends cleaning each roller for slurry after usage for longer lifetime and better
adjustment of blade. See separate instruction.
WARNING:
ALWAYS START AND FINISH A SAW CUT WITH THE SAME WIDTH OF BLADE. IF
BLADE TYPE OR WIDTH IS CHANGED, START A NEW SAW CUT. FAILURE TO DO THIS
CAN CAUSE EQUIPMENT DAMAGE AND/OR PERSONAL INJURY.
3.4 SHUTDOWN AND STORAGE
1. To stop the saw, release the trigger.
2. AFTER the blade has stopped rotating, lay the saw on a flat surface.
3. Stop the hydraulic power source following the procedure in the respective instruction manual.
4. Shut off water supply.
CAUTION:
ALWAYS SHUT OFF THE COOLING WATER WHEN THE TOOL IS NOT IN USE. LEAVING
THE WATER RUNNING UNATTENDED CAN CAUSE EQUIPMENT OR PROPERTY
DAMAGE.
5. Clean concrete slurry and debris off saw. Once concrete slurry is dry, it is very hard to remove and may hamper the
operation of moving parts.
6. Disconnect the hoses from the saw.

9
WARNING:
NEVER DISCONNECT ANY HYDRAULICALLY OPERATED PART OF THE SAW OR
REMOVE HYDRAULIC COMPONENTS, LINES, OR FITTINGS WHILE THE POWER
SOURCE IS RUNNING OR WHENEVER THE HYDRAULIC FLUID IS HOT.
LIQUID UNDER HIGH PRESSURE CAN PIERCE THE SKIN, CAUSING SERIOUS INJURY OR
DEATH. HOT LIQUID CAN CAUSE SERIOUS PERSONAL BURNS. IF AN INJURY OCCURS,
GET IMMEDIATE MEDICAL ATTENTION.
7. Secure the saw and hydraulic power source to prevent unauthorized use.
8. Store the saw in a clean, dry area away from exposure to high heat and humidity, water, other liquids, or freezing
temperatures. Avoid temperatures low enough to cause condensation on the blade when moving it from storage to a
higher temperature. Always handle and store blades carefully.
9. Do not stack material on top of the saw that may cause the blade to bend or deform.
3.5 Cold Weather Operation
If the ring saw is to be used during cold weather, preheat the hydraulic fluid at low power source speed. When using the normally
recommended fluids, fluid should be at or above freezing level 32°F/0° C before use. Damage to the hydraulic system or
hydraulic motor seals can result from use with fluids that is too viscous or thick.
Note: Remember to empty the saw of water after cutting in freezing conditions to avoid damage.
- Disconnect water hose.
- Orientate saw in a vertical position with the right Handle Valve (12) at the high point. This will allow water in the Roller
Frame (16) to drain out of the (4) roller areas. Duration 30 seconds.
- Reverse orientation, so that the right handle is at the lowest point in the vertical position. This will allow water to
Drain out of the Handle Valve (12). Duration 10 seconds.
3.6 Water Supply
Only use with water. Make sure water supply is sufficient. Abrasive material and too little water when cutting increases wear on
the drive wheel and the inner edge of the blade and may cause the blade to slip.
Note: The recommended minimum water supply is
2.5 gpm@ 50 psi.

10

4.3 BLADE AND DRIVE WHEEL REMOVAL AND INSTALLATION
Drive Wheel and Blade are purchased together as item (36), and must be replaced at the same time.
4.3.1 Blade and Drive Wheel Removal : For item numbers in ( ) after part descriptions below, refer to Part List on
pg. 16 and enclosed Exploded Assembly Drawings, pgs. 19 - 22.
1. Remove the (4) Roller Covers (39) with a phillip’s head screwdriver by removing (2) screws ph #10 (31) per each
cover.
2. Loosen the blade adjusting (knurled) Knob (41).
3. Loosen and remove the (2) 3/8”HHCS’s (25,20,44) using a 9/16” wrench.

11
4. Disconnect the plastic Water Hose (38) @ the ¼” 90 deg. elbow (40), by pressing the end of a flat head screwdriver
against the end of the black plastic elbow , force parallel with the tube , in the direction of the elbow. While doing this, pull
the plastic tube out of the elbow.
5. Remove the Roller Frame (1) with the blade (36) from the Gearbox Housing(16)
6. Remove the Blade Guide (18A), or (2) spacers(18B),(when optional blade guide is not purchased), by removing (2)
¼” HHCS’s (29,21,3) from Roller Frame.
7. Loosen (4) Rollers: by loosening each ¼” HHCS(6,4,5), then turning ea. Ecc. shaft (7) slot to 3 o-clock/9 o-clock
position from the blade, with a flat head screw driver.
8. Blade will now be free to slide out of Roller Frame slot opening.
9. Ref.: Drive Wheel Removal and Installation Diagram, Figure 4-1, pg. 12:
Remove the Drive Wheel (36) from the Gearbox Housing (16) by loosening the (2) #10 SHCS’s (23), with a 5/32”
(156”) hex. wrench. In order to keep the Drive Wheel from turning while loosening the (2) screws, hold the Drive
Wheel Mounting Flange (15) around the outside edge with a vice grip pliers.
4.3.2 Blade and Drive Wheel Installation (continued from above step).
1. Slide the Mounting Flange (15) onto the New Drive Wheel (36) and slide both onto the drive shaft of the Gearbox
Housing (16).
2. Insert the (2) lock washers (24) and (2) #10 SCHS’s (23) and tighten with a 5/32” (.156”) hex. wrench. In order to
keep the Drive Wheel from turning while tightening the (2) screws, hold the Drive Wheel Mounting Flange (15)
around the outside edge with a vice grip pliers
3. Insert the New Blade (36) into the Roller Frame (16) slot opening, with the blade side grooves positioned within the
(2) Guide Rollers item(2). Located on the far side while facing from the motor side.
4. Adjust the (4) Eccentric Shafts (7), so that the Blade is centered within the blade slot opening of the Roller Frame (1),
making sure the side grooves of the Blade are engaged within the Guide Rollers(2).
5. Tighten the (4) Eccentric Shafts (7), so that the (4) Rollers exert enough force on the blade, such that when the blade
is turned by hand, the rollers rotate. Also, while turning the blade by hand, when you put your thumb on each roller,
you can stop the rotation of that roller. This assures that the contact between the blade and the rollers is neither too
loose or too tight.
6. Tighten the (4) ¼” HHCS’s (6), one on each Roller. This locks the Rollers into position.
7. Position the Roller Frame (1), with the blade in position, onto the Gearbox Housing (16), so that the “V” groove on
the inside diameter of the Blade engages with the Drive Wheel (36) on the Gearbox Housing.
8. Adjust the Knurled Knob Adjusting Screw (41) so that the Blade “V” seats tightly against the Drive Wheel “V”. This
contact provides the frictional force necessary for the Drive Wheel to rotate the blade.
9. Tighten the (2) 3/8” HHCS’s (25, 20, 44) that attach the Roller Frame to the Gearbox Housing. This locks the
position of the Drive Wheel to the Blade.
10. Insert the Blade Guide (18A), or the (2) spacers (18B), into position of the Roller Frame (1) with (2) HHCS’s
(29,21,3).
11. Insert the plastic Hose (38) into the ¼” 90 Elbow (40).
12. Run the RingSaw (without water), and observe the Blade rotation and (4) Roller’s rotation:

12
-The blade should not appear loose, vibrate, or wabble. It should rotate smoothly.
-Each Roller should not appear loose while turning with the blade rotation.
-An indication that the blade is too tight against the Drive Wheel will be premature wear at the contact points
between these parts.
-The indication that the blade is too tight against the rollers is that you cannot stop the rotation of each roller by
hand while turning the blade with the other hand. This condition will also cause premature wearing of the blade
grooves and Guide Rollers (2) Fig.6-3. Pg. 18.
13. Install the (4) Roller Covers (39,31).
