and face and cause blindness or o_er serious
injury.

cient to cut material to be trimmed.
Do not run the engine at a higher speed than
necessary. The cutting line will cut efficiently
when the engine is run at less than ful_throttle.

area. Tapping on surfaces such as concrete
or asphalt can cause excessive wear to the
trimmer head.If the line is worn down to 2
inches (5 cm) or less, more than one tap will
