For Safe Operation
You must be qualified for the safe operation of the U.S.SAWS 5” Grinder. You must clearly understand the written instructions supplied by U.S.SAWS, be trained – including actual operation – & know the safety rules & regulations for the job site. It is a safe practice to point out & explain safety signs & procedures to others & to make sure they understand the importance of following these instructions.
Be Safe
Human error results from many factors: carelessness, fatigue, sensory overload, preoccupation, unfamiliarity with the machine or attachments, or drugs or alcohol, to name a few. You can avoid serious injury or death caused by these & other unsafe work practices. Be safe and never assume accidents cannot happen to you. For your safety and the safety of others, act safely and encourage your fellow workers to operate safely as well.

• Read and understand the operator’s manual before using this machine. Failure to follow operating instructions could result in injury or damage to equipment.
• Always wear protective glasses or full face protection.
• Wear Head Protection and breathing protection, and the use of hearing protection is mandatory.
• Wear safety boots when operating this machine.
• Wear appropriate clothing.
• Wear hand protection.
• Wear proper electrostatic grounding equipment at all times.

SAFETY INSTRUCTIONS

KNOW THE RULES AND YOUR EQUIPMENT

• Most job sites have rules governing equipment use & maintenance.
• Before starting at a new work location, check with the supervisor or safety coordinator. Ask about any rules or regulations you need to abide.
• OSHA enforces federal laws within the United States that apply to the safe operation, application, & maintenance of equipment on job sites. It is the employer’s responsibility to comply with these laws.
• Do not operate this machine unless you have read the operations and maintenance manual carefully.

RECEIVE PROPER TRAINING

• Do not operate this machine unless you have received operational and maintenance training from a U.S.SAWS representative or an authorized distributor for U.S.SAWS.

PROTECT YOUR FEET

• Observe all applicable local, state and federal safety regulations.
• Wear OSHA-approved foot protection.

PROTECT YOUR EYES

• Observe all applicable local, state and federal safety regulations.
• Wear OSHA-approved safety glasses.

PROTECT YOUR LUNGS
Breathable silica may be generated by the use of this product. Silica can cause severe and permanent lung damage, cancer, and other serious diseases. Do not breathe the dust. Do not rely on your sight or smell to determine if the dust is in the air. Silica may be in the air without a visible dust cloud. If air monitoring equipment for silica is not provided by your employer at your work site, you MUST wear appropriate respiratory protection when using or servicing the machine. Consult your employer and OSHA regarding the appropriate respiratory protection.

PROTECT YOUR HEARING

• Observe all applicable local, state and federal safety regulations.
• Wear OSHA-approved hearing protection.

DRESS PROPERLY

• Do not wear loose clothing or jewellery that can be caught in moving parts. Wear a protective hair covering to contain long hair.
• Keep hair away from the motor air vent. Rubber gloves and non-skid footwear are recommended when working outdoors.

AVOID A DANGEROUS ENVIRONMENT
Do not expose the machine to rain. Do not use the machine in wet conditions. Water entering a power tool will increase the risk of electric shock. Keep the work area well-lit. When working at an elevated location, pay attention to the articles and persons below. If operating the power tool in damp locations is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. The use of a GFCI reduces the risk of electric shock.

ELECTRICAL SAFETY
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce the risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

ELECTRICAL CORD MANAGEMENT
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep the cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

AVOID ANY AREAS OR ACTIONS THAT EXPOSE YOU TO CARBON MONOXIDE
Exhaust gas from gasoline engines contains dangerous carbon monoxide. Breathing it can cause unconsciousness and even kill you. Always operate gasoline engine machines in a well-ventilated area. Do not operate in areas where exhaust fumes could accumulate without wearing appropriate respiratory protection. Consult your employer and OSHA regarding the use of an appropriate respirator for dangerous carbon monoxide gases.

KEEP THE WORK AREA CLEAN. DO NOT RUN OVER ANYTHING
Loose objects could be thrown from the crack. Make sure the area to be cut is clear from people and any loose objects, nuts, bolts, etc. Never run over any loose objects.

KEEP CHILDREN AND VISITORS AWAY
Do not allow anyone to stand in line with the blade path. Do not let children or visitors contact the machine or extension cord. Keep children and visitors away from the work area.

KEEP FIRM GRIP ON MACHINE
Keep a firm hold on the handle grips and maintain control of the machine until the blade completely stops.

SHUT OFF THE MACHINE
When not in use, before servicing and when changing accessories, shut off the engine. Release the lever switch and move the on/ off switch to the OFF position. Move the fuel valve lever to the OFF position.

STORE IDLE EQUIPMENT
The machine and tools should be stored in a dry and secure location when not in use. Keep equipment out of reach of children.

OBTAIN SAFETY DATA SHEET (SDS) FOR ALL WORKSURFACE MATERIALS
This includes primers, all coatings, adhesives, tile and crack filling materials, etc. Do not attempt to cut, clean out or remove material without SDS information. Consult the SDS sheet for hazard information. Be aware that some materials are as explosive as a speck of dust.

DO NOT OVERREACH
Keep proper footing and balance at all times.

MAINTAIN MACHINE WITH CARE
Keep the machine clean and follow maintenance procedures for better and safer performance. Keep handles dry, clean, and free from oil and grease. Follow instructions for lubricating and changing accessories.

REMOVE ADJUSTING TOOLS
Form a habit of checking to see that tools such as adjusting wrenches are removed from the machine and properly stored before starting the engine.

STAY ALERT
Watch what you are doing. Use common sense. Do not operate the machine when you are fatigued.

DO NOT USE DRUGS, ALCOHOL, MEDICATION
Do not operate the machine while under the influence of drugs, alcohol, or any medication.

KEEP THE RIGHT PARTS IN THE RIGHT POSITIONS
Do not operate the machine with parts missing or improperly mounted.

CHECK DAMAGED PARTS
Verify all machine guards are in good condition and will function properly before using the machine. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect machine operation. A guard, power switch or other part that is damaged should be properly repaired or replaced by an authorized service centre unless indicated elsewhere in this instruction manual. Do not operate the machine if the lever or engine on/off switch does not function properly.

SECURELY MOUNT ACCESSORIES TO THE MACHINE
Extra care must be taken at an elevated location to prevent injury to someone on a lower level in the event the tool or accessory should drop. Do not operate without fall protection for the operator and debris protection for the public.

NEVER TOUCH THE MOVING PARTS
Never touch moving parts such as blades, belts and others.

STOP OPERATION IMMEDIATELY IF ANY ABNORMALITY IS DETECTED
Stop using the machine immediately if any abnormalities are observed during operation. Examples of abnormalities include unusual noise and vibration.

WHEN REPLACING A PART, USE THE SAME TYPE AND QUALITY
When replacing a part with a new one, use only the same type and quality of the new part. Never attempt to repair a machine if you are unfamiliar with the proper procedures and techniques required.

LOAD AND UNLOAD SAFELY
Use proper heavy-lifting procedures. Read & understand manuals before loading & unloading.

SAVE THESE INSTRUCTIONS
Refer to this operations and maintenance manual as well as any additional instructions included from other manufacturers and organizations such as Metabo® and the Masonry and Concrete Saw Manufacturers Institute®. Never permit anyone to operate the machine without proper instructions.

DUST WARNING
Cutting, especially when DRY cutting, generates dust that comes from the material being cut, which frequently contains silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Exposure to excessive amounts of such dust can cause:

• Respiratory diseases (affecting your ability to breathe), including chronic bronchitis, silicosis and pulmonary fibrosis from exposure to silica. These diseases may be fatal;
• Skin irritation and rash; and
• Cancer according to NTP and IARC
• National Toxicology Program, International Agency for Research on Cancer

Take precautionary steps

• Avoid inhalation of and skin contact with dust, mist and fumes;
• Wet cut when feasible, to minimize dust;
• Wear and ensure that all bystanders wear appropriate respiratory protection such as dust masks designed to filter out microscopic particles. (See OSHA 29 CFR Part 1910.1200)

California Prop 65 Warning: Use of this product can cause exposure to materials known to the State of California to cause cancer and/or birth defects or other reproductive harm.
