Stihl TS 800 Instruction Manual - Page 22

English If the operator cannot achieve and maintain a sufficient flow rate using the highest flow setting on the cut-off machine, connect the cut-off machine to a water source with sufficient pressure to deliver at least 20 fluid ounces (0.6 liters) of water per minute. Inhalation of airborne crystalline silica can cause serious or fatal injury or illness, such as kidney disease and respiratory diseases, including silicosis and lung cancer. To reduce the risk of serious or fatal respiratory disease or other illness when a source of water with adequate pressure is unavailable, when the water flow cannot be confirmed or when worksite conditions do not allow use of 20 fluid ounces per minute, the operator and any bystanders should always wear a NIOSH-approved respirator that is rated for the material being cut and appropriate for worksitespecific conditions. The respirator must have an Assigned Protection Factor sufficient to provide the level of respiratory protection needed for the material being cut and appropriate for worksite-specific conditions. Consult your employer for information regarding worksite conditions and the material you are cutting. Your employer is likely to have in place an OSHArequired respiratory protection program and can provide information regarding the type and level of respiratory protection needed for your worksite. Information is also available from OSHA at www.OSHA.gov. Wet Cutting with Diamond Cutting Wheels STIHL diamond cutting wheels are suitable for wet cutting. Wet cut whenever feasible. It increases the service life of diamond wheels, reduces reactive forces and will help control dust. The cutting wheel must be supplied with at least 20 fl. oz. (0.6 liters) of water per minute for proper dust suppression. To reduce the risk of serious or fatal respiratory disease or other illness when this flow rate cannot be achieved, maintained or confirmed, the operator and any bystanders should always wear a NIOSH-approved respirator that is rated for the material being cut and appropriate for worksite-specific conditions. The respirator must have an Assigned Protection Factor sufficient to provide the level of respiratory protection needed for the material being cut and worksite-specific conditions. Even if wet cutting at the recommended flow rate, an operator who is working with the machine for more than two hours in one day, along with any bystanders, should always wear a NIOSH-approved respirator that is rated for the material being cut and appropriate for worksite-specific conditions. Consult your employer for information regarding the material you are cutting and your worksite conditions. Your employer is likely to have in place an OSHA-required respiratory protection program and can provide information regarding the type and level of respiratory protection needed for your worksite. Information is also available from OSHA at www.OSHA.gov. Before wet cutting, make sure water will not damage the floor, building or other property, the material being cut or any surrounding objects. Make sure that "run-off" will not cause any type of environmental damage or come into contact with electrical sources. WARNING STIHL recommends the use of only STIHL-branded cutting wheels on your cut-off machine. Use of non-STIHL cutting wheels may be extremely dangerous. See the chapter "Reducing the Risk of Kickback Injury" in this instruction manual. WARNING To reduce the risk of electrocution to you or bystanders, do not allow water or sludge to contact live electric wires or other electrical power sources. Composite Cutting Wheels for Wet or Dry Cutting Composite Cutting Wheels Designed for Dry Cutting WARNING To reduce the risk of injury from wheel breakage, never use water with a composite wheel that is not specifically designed for wet cutting. 20 TS 700, TS 800
