English operator to drive under overhanging obstacles and fit the mower into trailers. Lower the roll bar only when absolutely necessary. Never use the seat belt when the roll bar is down. Raise the roll bar as soon as overhead clearance permits. Never remove the roll bar. WARNING In order to avoid serious injury or death from roll over, follow the warnings listed below. ■■ Always fasten the seat belt when the roll bar is in the raised position. ■■ Never use the seat belt when the roll bar is down. ■■ Keep the roll bar raised and locked unless absolutely necessary to pass under an obstacle. There is no roll over protection when the roll bar is down. ■■ Overhanging obstacles can be dangerous. Before passing under tree branches and other obstacles, always ensure sufficient clearance. If absolutely necessary, lower the roll bar to pass under the object. Return the roll bar to the raised and locked position immediately after clearing the obstacle. ■■ Never modify, alter or remove the roll bar. ■■ The roll bar has a maximum weight limit. Never exceed the weight rating marked on the roll bar. ■■ Read and follow STIHL's instructions about inspecting and maintaining the ROPS. Inspecting the Roll Bar WARNING Failure to properly inspect and maintain the roll bar can result in serious injury or death. Inspect the roll bar to ensure that it has not been damaged or weakened or otherwise compromised during use. Inspect for evidence of misuse, wear, modification, or damage. Contact your authorized STIHL servicing dealer if you have any questions about the condition of the roll bar. ■■ Never attempt to repair a roll bar. Because microfactures in the roll bar can reduce the effectiveness of a roll bar, it must be inspected and replaced by the manufacturer following a collision, roll over, or other overhead impact. Never attempt to weld on the roll bar, straighten its segments, or otherwise repair the components of the roll bar. Likewise, never drill holes into the roll bar or weld anything to it -- this will reduce its structural integrity. 12 Operator Safety ■■ Before using the mower for the first time: 1. Make sure the mower's gross weight, including attachments, payload, and operator, is below the maximum weight stated on the roll bar label. 2. Check for missing, damaged, or loose hardware. Make sure all of the components are in place and securely attached. 3. Check for proper installation of the components of the roll bar. If you have questions, consult your authorized STIHL servicing dealer. ■■ EVERY 100 HOURS - Inspect the roll bar and mounting hardware for: 1. Deformation or twisting of the roll bar. 2. Missing or damaged hardware -- including hardware that cannot be re-tightened. 3. Cracks in the metal tubing or welds. 4. Corrosion on the roll bar or the ROPS hardware. 5. Unauthorized welds, holes, or hardware. 6. In addition, confirm that the roll bar label and ROPS warning information is still in place and readable. Inspecting the Seat Belt WARNING The seat belt is another component of the roll over protection system. Inspect the seat belt regularly to ensure that it can perform its intended safety function. ■■ Before each use, check for wear or damage caused by normal degradation, misuse, modification, or abuse. 1. Check for fraying, cuts, or other wear in the fabric of the seat belt. 2. Check the seat belt for dirt and debris. Remove dirt. Confirm proper mechanical operation by testing extension and retraction of the belt and the mechanism securing the buckle and latch. If the polymer or metal parts are damaged or cracked, or if latching and releasing the buckle are difficult, or if the seat belt has any other mechanical problems, have the seat belt replaced by your authorized STIHL servicing dealer.
