I. PREPARATION

A. Safety Precautions

Important! The following safety precautions must always be observed.

Hazard Symbols

Motor components can get extremely hot from operation. To prevent

burns, do not touch the engine or related parts while the engine is

running or immediately after it is turned off. Never operate the engine

with any heat shields or guards removed.

Keep all guards in place when operating any piece of equipment

Keep hands, feet, hair, and clothing away from all rotating parts

Never tamper with the governor components of settings to increase

the maximum speed. Severe personal injury and damage to the

engine or equipment can result if operated at speed above maximum.

Always obey the maximum speed rating of blade.

DO NOT LIFT THE SAW BY THE HANDLE BARS

Dust and Silica Warning

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

sheet and/or consult your employer, the material manufacturer/supplier, governmental

agencies such as OSHA and NIOSH and other sources on hazardous materials and

make certain to comply with all product warnings and instructions for the safe and

effective use of the material being cut. 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 recommendations of the manufacturer/supplier,

OSHA/NIOSH, and occupational and trade associations. Water should be used for dust

suppression when wet cutting is feasible. When the hazards from inhalation of dust,

mists and fumes cannot be eliminated through engineering controls such as vacuum

and/or water mist, the operator and any bystanders should always wear a respirator

approved by NIOSH/MSHA for the material being cut.

Use Approved:

Eye Protection Hearing

Protection Head Protection

1. Before mounting any blade on the saw, the blade should be inspected for any

damage which might have occurred during shipment, handling or previous use.

2. The blade collars and arbors should be cleaned and examined for damage

before mounting the blade.

3. The blade must be properly fitted over the arbor with the drive pin on the

outside collar projecting through the drive pin hole on the blade and inside

collar.

4. The blade shaft nut, which is a left-hand thread nut, must be tightened securely

against the outside blade shaft collar.

5. The blade must be operated within the specified maximum operating speed

listed on the blade.

6. The blade guard must be in place with the nose guard down and locked when

the saw is running.

7. The operator should wear safety glasses and any other appropriate safety

equipment.

8. When starting the saw, the operator should stand away and to the side of the

blade.

9. If for any reason the saw should stall in the cut, raise the blade out of the cut.

Check the outside blade shaft collar and nut for tightness. Inspect the blade

for damage before restarting the saw. Use caution when resuming a cut. Be

certain that the blade is in alignment with the previous cut.

10.During cutting operations, do not exert excess side pressure on the handles as

a method of steering. Do not force the blade into the cut by lowering the blade

too fast or by pushing the saw too fast.

You Are Responsible For Your Safety!!!

I. PREPARATION

B. Assembly

The GC25E UP compact Joint Clean Out and Concrete saws are shipped

completely assembled and ready for use except for diamond blade, Handle Bar

position, electrical extension cord (not supplied), and power supply. Inspect the saw

for shipping damage. If any damage is found, contact the shipper immediately and

file a freight claim. Saint-Gobain Abrasives, Inc. is not responsible for any freight-

related damages.

Adjust the Handle Bars Position:

1. Remove the GC25E UP from the box.

2. Remove the Quick Release Pin P/N: 241055 out of its retaining hole

3. Loosen the Black Knob P/N: 241054.

4. Rotate the Handle Bar from the lowered storage position to the desired

position.

5. Align the hole in the Handle Bar with the holes in the frame.

6. Attach the Quick Release Pin P/N: 241055 by pushing it through the hole in

the Frame and then the hole in the Handle Bar. Make sure that the Quick

Release Pin passes all the way through both sides of the Frame.

7. Tighten the Black Knob P/N: 241054.

Read and understand the remaining sections of this Owner's Manual. NOTE: Do not

install the blade until it is time to use the saw. ANSI regulations prohibit the

transportation of any concrete saw with the blade installed.

1) Net Horsepower Rating provided by engine the manufacturer measured in accordance to SAE j1349 @ 3,600 RPM. The engine may vary from this value. Actual

horsepower on the machine will vary due to operating speed of engine, belt tension, environmental conditions, machine maintenance, and other variables.

2) Starting Amps are instantaneous – for best results use with a 30Amp circuit.

The GC25E UP Joint Clean Out and Concrete Saw was designed from the ground up to

be a High Performance Multiple Application saw. The GC25E UP is the best electric

Joint Clean Out saw on the market and is capable of cutting Cured Concrete and

Asphalt.

Used For Cutting Multiple Applications:

Joint Clean Out

Joint Widening

Cured Concrete

Asphalt

Features that make the GC25E UP a High Performance Joint Clean Out and

Concrete Saw:

Blade in center line of saw makes it easier to push and the machine tracks

straighter. The center line blade also helps the GC25E UP to roll straight while

cutting due to the blade being parallel to the blade.

Reinforced all steel frame reduces bending, flexing, and vibrations which can

damaged the concrete. The reinforced all steel frame is also stronger than the

competitive models

Soft Silicone Rubber wheels that are based off of a Norton Patient to absorb

vibrations that can create machine movement. The wheels also feature a

concave profile that helps the machine to roll over small objects with out

upsetting the blade.

10” maximum blade capacity with standard 5/8” arbor. The GC25E UP can be

used with 7” to 10” diameter Norton blades.

Hand Wheel with Depth Adjustment Screw & Depth allows precise depth

adjustments up to 3-1/2” deep when used with a 10” blade.

Fully adjustable dust removal Shroud system with standard vacuum hose

attachment helps to keep dust down.

Up cut helps with the extraction of dust when joint cleaning.

Front and rear pointers for precise alignment.

Handle Bar and Pointer folds up for compact easy transport.

Light in weight.

Dual voltage motor, change voltages from 115v to 230v by flipping a switch.

The GC25E UP is an extremely simple machine to operate.

The GC25E UP is designed for Joint Clean Out, Joint Widening, and cutting

multiple applications: such as Cured Concrete and Asphalt.

Includes a free 8” Joint Clean Out Blade.

D. Pointer Alignment

1. Use a straight edge, and carefully mark a line 12 feet long on a smooth level

surface.

2. Place the saw blade on the marked line, move the saw to the center of the

marked line and then lower the blade until it is about 1/16” above the marked

line.

3. Measure from each end of the saw frame to insure that the frame is parallel to the

marked line. Adjust the saw as needed.

4. With the blade centered on the marked line and the saw frame parallel to the

marked line, lower the front pointer.

5. Adjust the nylon nuts until the pointer is aligned with the marked line.
