1 SAFETY
1.1 INTRODUCTION
Your Reimann & Georger Corporation TS14 Trenchsaw 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 that 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 that could cause injury. Read them carefully. If a label comes off or becomes
illegible, contact Reimann & Georger Corporation for a free replacement.
1.4 TS14 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.

2
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.
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 maximum flow and pressure rating of the saw, which is 8 gpm at 2500 psi.

3 OPERATION
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.
1. Hydraulic system
2. Flanges 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. Clean fittings before making connections to prevent contamination of hydraulic system. First 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.
3. Pressure relief valve must not exceed 2500 psi @ 8 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.
3.1.2 Flanges and Blade
1. Inspect the flange and arbor flange for gouges, hairline cracks, and wear. Replace these flanges immediately if any
of these conditions are present as described in Chapter 4.
2. Be sure flanges are clean and straight so blade will run true on sides.
3. Always use the blade recommended by the blade manufacturer for your application. Use approved dry cutting type
blades in dry cutting operations and approved wet cutting type blades in wet cutting operations.
4. Inspect the blade for cracks, chips, gouges, or loose or missing tips. Destroy the blade if any of these conditions are
present.
5. Insure a blade is installed to blade manufacturer’s specified direction of rotation. Saw rotation is clockwise as
viewed from the blade side of the saw.
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.
3. Insure the power supply is turned off. Adjust the blade guard to provide the best operator protection from the angle
of the cut to be made. To adjust the blade guard, loosen the two knobs and rotate the guard to the desired position.
Then retighten the knobs securely.
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 hydraulic flow and pressure rating of the hydraulic power unit before using to prevent equipment
damage. Do not exceed the maximum hydraulic flow rate and pressure of 8 gpm (30 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 hydraulic power source 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. 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. Provide rigid support and “hold down” of piece being cut—both sides of the cut, if practical.
2. Grasp the auxiliary handle with your left hand. Use the appropriate part of the handle for making vertical or
horizontal cuts.
3. Grasp the trigger with your right hand.
4. Position the saw in the appropriate place to make the desired cut.
5. Disengage the trigger lockout. Then depress (squeeze) the trigger to start the saw. Never exceed either the blade
maximum operating speed of 4100 rpm or the blade manufacturer’s rated speed.
6. 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.
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.
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.
