Fuel Safety
WARNING! Take care when handling fuel. Bear in mind the risk of fi re, explosion and inhaling fumes.
• Only store fuel in containers approved for the purpose.
• Only refuel machine with engine OFF. Never remove fuel cap and fill the fuel tank while the engine is running.
• Always refuel in a well ventilated area.
• Never fi ll a fuel tank indoors.
• Allow engine to cool before refueling.
Never fuel machine in vicinity of sparks or flames. Do not use machine in flammable area.
Do not smoke while fueling or using the machine.
• Move machine 10 feet (3 meters) from refueling point before starting engine.
• Never start the machine:
1) If fuel has been spilled on the machine. Wipe off spillage and allow remaining fuel to evaporate.
2) If you have spilled fuel on yourself or your clothes. Use soap and water to wash any part of your body that has come in contact with fuel.
3) If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.
• Store and transport machine and fuel so that there is no risk of any leakage or fumes coming into contact with sparks or flames, for example, electrical machinery or electric motors, electrical relays / switches, or boilers.
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 amount of such dust can cause:
• Respiratory diseases (affecting your ability to breath), 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.
WARNING
POISON EXHAUST GAS
THIS SAW IS SHIPPED FROM THE FACTORY WITHOUT A CATALYTIC CONVERTER.
THE ENGINE PRODUCES CARBON MONOXIDE EXHAUST EMISSIONS AND IS NOT SAFE FOR USE IN ENCLOSED AREAS. USE OF A CATALYTIC CONVERTER REDUCES THE CARBON MONOXIDE EXHAUST EMISSIONS, BUT STILL IS NOT SAFE FOR USE IN ENCLOSED AREAS.
USE ONLY IN WELL-VENTILATED AREAS. WORK SITE AIR QUALITY MUST COMPLY WITH
OSHA 29 CFR 1910.1000 PER TABLE Z-1, LIMITS FOR AIR CONTAMINANTS.
MONITOR WORKSPACE AIR QUALITY TO INSURE COMPLIANCE. FAILURE TO COMPLY WILL RESULT IN DANGER TO LIFE AND CAUSE PERMANENT INJURY OR DEATH
General Information
Carbon monoxide (CO) has the distinction of being one of the few commonly encountered industrial gasses that is both highly toxic (poison) and odorless. When inhaled, CO acts as a chemical asphyxiant by preferentially combining with hemoglobin in the blood stream. As a result, the hemoglobin is not able to transport its normal amount of oxygen, which results in under-oxygenation of tissues. Symptoms of low-level CO exposure include headaches, dizziness, confusion, and nausea. However, loss of consciousness, permanent injury and death may result from continued or more intense exposure. Because of the health hazards associated with CO inhalation, the Occupational Safety and Health Administration (OSHA) have imposed personal exposure limits. The OSHA exposure limits, which are specified in the 29 CFR 1910.1000 (1998 Revision), allow for a 200 PPM Ceiling Limit and a TWA of 35 PPM per 8-hour shift/40-hr workweek. It is strongly recommended that the OSHA 29 CFR 1910.1000 (Code of Federal Regulations) be consulted for more information on exposure limits for various hazardous materials. If CO Poisoning is suspected immediately remove the victim to fresh air and obtain emergency medical attention.
Proper Ventilation:
THIS SAW IS SHIPPED FROM THE FACTORY WITHOUT A CATALYTIC CONVERTER. It is important to be aware that saws with catalytic converters reduce CO and hydrocarbon (HC) emissions. The exhaust still contains CO. If the
workspace is too confined or under-ventilated, CO may accumulate until it eventually exceeds OSHA limits. When this happens, action must be taken to remove workers from areas of high concentration. Operators and work area
supervisors should take precautions to insure adequate ventilation of the workspace at all times. Carbon monoxide detection monitors should be used to determine that adequate ventilation exists.
WARNING
HEARING HAZARD
DURING NORMAL USE OF THIS MACHINE, OPERATOR MAY BE EXPOSED TO A NOISE
LEVEL EQUAL TO 85 dB (A) OR GREATER. TEMPORARY AND/OR PERMANENT DAMAGE TO HEARING
MAY RESULT. HEARING PROTECTION REQUIRED.
