Stihl TS 500i Instruction Manual - Page 21

Contact your local fire agency or forest service for the laws or regulations relating to fire protection requirements. Even if the spark arrester is in place, it may not be advisable to use gasolinepowered equipment, including cut-off machines, in hot, dry conditions or around dry vegetation or brush. Contact your local fire authorities or the U.S. Forest Service if you have any question about whether conditions are suitable for the use of a cut-off machine. For any maintenance please refer to the maintenance chart and to the warranty statement near the end of this manual. Do not store a cut-off machine with a wheel mounted on the machine. Store the cut-off machine in a high or locked place, out of reach and inaccessible to children. Empty the fuel tank before storing your cut-off machine for longer than a few days. Store fuel only in correctly labeled and approved containers. Avoid direct skin contact and do not inhale the gas vapors. Dispose of fuel in accordance with all applicable laws and regulations. Sample Applications Water Connection - A water attachment kit is mounted on the machine for use with all types of water supply. - A pressurized 2.6 gallon (10 liter) water tank also is available from STIHL for wet cutting. - A water tank for mounting on the Cutquik cart is also available for wet cutting. For proper dust suppression, always ensure that you have sufficient water pressure to produce the recommended flow rate of 20 fluid ounces per minute (0.6 liters/minute), regardless of the water source. The pressure and flow rate available from the water source will affect the actual amount of water available for dust suppression when wet cutting with your cut-off machine. For example, when using a pressurized or gravity-fed water tank, water pressure will decrease as the water level in the tank decreases. STIHL recommends using the highest water flow setting on your cut-off machine whenever possible. Maintain pressure by re-filling gravity-fed tanks and re-pressurizing pressurized tanks periodically. STIHL recommends always wet cutting at the highest flow rate when conditions permit. The highest flow setting is obtained by pressing the (+) control English button on the water control panel 9 times in succession or by depressing it for at least 5 seconds. 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.
