DANGER
The blade retaining nut equipped with this unit is a nylon lock nut that provides addi-
tional resistance to loosening. Always use a new nylon lock nut when replacing the
blade or when the nylon or the nut becomes worn or damaged. Only use genuine
ECHO nylon lock nuts as replacement parts when servicing this unit.
CAUTION
Fasten output shaft using locking tool securely in order to avoid the possibility of
output shaft rotating when mounting cutting blade which will prevent the cutting
blade fastening nut from being tightened sufficiently.
Wear gloves to reduce the risk of injury caused by unintentional contact with the
blade.
NOTE
Check to be sure the locking tool is fully engaged to prevent the output shaft from turning.
