Stihl TS 500i Instruction Manual - Page 7

Cut-off machine noise may damage your hearing. Always wear sound barriers (ear plugs or ear muffs) to help protect your hearing. Regular users should have their hearing checked regularly. WARNING To reduce the risk of serious or fatal respiratory disease or other illness, the operator and any bystanders should always wear a respirator that is approved by NIOSH for the material being cut and appropriate for worksite-specific conditions anytime wet cutting at the flow rate recommended in this instruction manual is not utilized or cannot be confirmed. The respirator must have an Assigned Protection Factor sufficient to provide the level of respiratory protection needed for the material being cut and worksitespecific 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 relating to the respirator needed for the material you are cutting and your worksite-specific 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 also is available from OSHA at www.OSHA.gov. For additional details and warnings on this subject, see information under "Working Conditions" in this instruction manual. THE POWER TOOL For illustrations and definitions of the parts of the cut-off machine, see the chapter "Main Parts." WARNING Never modify a cut-off machine in any way. Only STIHL branded parts and cutting attachments expressly approved by STIHL for use with the specific STIHL cut-off machine models are recommended. Although certain other parts or attachments may be useable, their use may be extremely dangerous. Abrasive Cutting Wheels WARNING Before mounting the cutting wheel, make sure that the maximum operating wheel speed is above or equal to the spindle speed of your cut-off machine as provided in the specifications of this manual. A wheel that is not rated for the maximum spindle speed of the cut-off English machine may shatter or break and poses a threat of serious or fatal injury to the operator and other nearby persons. WARNING Never use a reducer bushing inserted into the wheel to reduce the diameter of the arbor hole. It may slip out of place, causing out-of-roundness, vibration, wheel breakage or loss of control, resulting in the possibility of severe or fatal injury. WARNING Wheels that are not STIHL branded may be more likely to wobble, shatter, break and/or create other hazards, such as increased reactive forces. Use only wheels with approved RPM ratings. Read and follow any additional safety precautions that accompany the wheel. TS 480i, TS 500i 5
