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 com-
fortable position with the rear handle about hip height.
Always operate trimmer at full throttle. 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 oil dripping from the muffler.
