Safety guard extension (exclusively for use with nylon string head)

The string cutting blade housed in the plas- tic shield will cut the nylon string to opti-

mum length; a string that is too long reduces the rotation speed of the engine and interferes with cutting efficiency, as well as increasing the risk of injury.

The extension (B) should be installed only for use with the nylon string head, with the aid of the string cutter blade (L), that regulates the length of the string and thus the cutting diameter. For cor- rect assembly see the illustration on the cover and perform the following sequence of steps: Insert the extension (B) on the safety guard (A) at the reference notches (C), and fasten with the screws (D), then apply the string cutter blade (L) and fasten it with the screw (E) (Make sure the screws are tightened all the way (E) and are not loosened by the vibrations. If necessary, tighten them again).

ting blade and replace the flange guard (A) with the sawtooth blade guard (H).
