Using a Blade C3410
WARNING!
Before working with a blade- equipped unit, always inspect and clean the area of objects that could interfere with or damage the blade.
Never use a blade near sidewalks, fence posts, buildings or other objects that could cause injury or damage.
Never use a blade for purposes other than those for which it was designed.
Whenever you strike a hard object with a blade, always stop the brushcutter and carefully inspect the blade for damage. NEVER OPERATE THE BRUSHCUTTER WITH A DAMAGED BLADE!
A
Always make sure the cutting at- tachment shield is properly installed before operating this unit.
Blade Thrust
‘Blade thrust’ is a sudden sideways or backward motion of the brushcutter. Such motion may occur when the blade jams or catches on an object such as a sapling tree or tree stump. BE CONSTANTLY ALERT FOR BLADE THRUST AND GUARD AGAINST ITS EFFECTS!
Brushcutter Handlebar
A brushcutter handlebar or barrier bar helps prevent the operator from moving forward, or the unit moving rearward, thus preventing inadvertent bodily contact with the blade. ALWAYS KEEP THE HANDLEBAR OR BARRIER BAR SECURELY IN PLACE ON THE UNIT!
Brushcutter Shoulder Strap
A shoulder strap provides additional protection against blade thrust. In addition, a shoulder strap gives significant support and comfort to help ensure safe and efficient operation.
When operating a C3410 with a blade, make sure both the handle and shoulder strap are adjusted to the size of the opera- tor using the unit.
Engine Operating Speeds
Operate the unit at full throttle while cut- ting. Best fuel efficiency is obtained by releasing the throttle when swinging back after a cut.
To prevent possible engine damage, do not allow the brushcutter to run at high speeds without a load.
Avoid operating the engine at low speeds. Doing so can lead to rapid clutch wear. In addition,
