Do not rest or place your arm, hand, or any body part against the engine housing during trimmer operation. Only hold the trimmer as shown in Figure 10 with all body parts clear of engine housing. Extended contact with the engine housing can result in burns or other injuries. WARNING: Always position the unit on the operator's right side. The use of the unit on the operator's left side will expose the user to hot surfaces and can result in possible burn injury. WARNING: To avoid burns from hot surfaces, never operate unit with the bottom of the engine above waist level. Hold the trimmer with your right hand on the rear handle and your left hand on the front handle. Keep a firm grip with both hands while in operation. Trimmer should be held at a comfortable position with the rear handle about hip height. Always operate trimmer in RUN position. Cut tall grass from the top down. This will prevent grass from wrapping around the shaft housing and string head which could cause damage from overheating. If grass becomes wrapped around the string head, STOP THE ENGINE, disconnect the spark plug wire, and remove the grass. Prolonged cutting at partial throttle will result in lubricant dripping from the muffler. WARNING: Always hold the string trimmer away from the body keeping clearance between the body and the product. Any contact with the housing or string trimmer cutting head can result in burns and/or other serious personal injury. 9 - English
