Installing blade

If worn nut and cup for blade are used, there is a danger of blade getting loose.
Replace them with new ones.
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.
Inspect blades before installation.
