5 IMPORTANT SAFETY INSTRUCTIONS - When the engine is started, the engine speed with the starting throttle lock engaged will be fast enough for the clutch to engage and move the cutting attachment. - Once the engine has started, immediately blip the throttle trigger, which should cause the choke lever to move to the run position and allow the engine to slow down to idle. 5.7.3 Holding and Controlling the Trimmer / Brushcutter WARNING ￭ To maintain a firm grip and properly control your trimmer / brushcutter: - Keep the handles clean and dry at all times. Keep them free of moisture, pitch, oil, grease and resin. ￭ Operating the trimmer / brushcutter with one hand may lead to loss of control and is extremely dangerous. To reduce the risk of serious or fatal injury to the operator or bystanders from loss of control: - Never attempt to operate the trimmer / brushcutter with one hand. ￭ 0000090519-002 English ￭ To reduce the risk of serious or fatal injuries to the operator or bystanders from loss of control: - Place your right hand on the control handle and your left hand on the loop handle (see illustration). Lefthanders must follow these instructions too. - Wrap your fingers tightly around the handles, keeping the handles cradled between your thumb and forefinger (see illustration). - Position the power tool so that all parts of your body are clear of the cutting attachment whenever the engine is running. - The operator must use a harness as instructed in this manual, @ 23.1 ￭ When the unit is mounted with a metal cutting attachment, the operator must take special precautions to reduce the risk of severe injury from loss of control and contact with the cutting blade: - The operator must mount the proper deflector as instructed in this manual, @ 8.4. - The operator must use a harness, @ 9.1. ￭ Working with the cutting attachment above ground level or perpendicular to the ground increases the risk of severe injury from thrown objects. It also exposes more of the cutting attachment and makes the unit more difficult to control, increasing the risk of injury. To reduce the risk of serious or fatal injury from loss of control or thrown objects: - Keep the cutting attachment at ground level, parallel to the ground. ￭ To reduce the risk of serious or fatal injuries to the operator or bystanders from contact with the cutting attachment: - Keep hands, feet and other body parts away from the cutting attachment. - Never touch a moving cutting attachment with your hand or any other part of your body. - Do not touch the cutting attachment while the engine is running. 0458-853-8601-B 15
