• To reduce fire hazard, replace a faulty muffler and
spark arrestor. Keep the engine and muffler free from
grass, leaves, excessive grease or carbon build up.
While Operating with the Cutting Blade
• Read and understand all safety warnings before
operating this unit.
• Always use the shoulder harness when using the
brush blade accessory.
• Keep the J-handle between the operator and cutting
attachment or blade at all times.
• NEVER cut with the cutting blade located over 30
inches (76 cm) or more above the ground level.
• Blade thrust may occur when the spinning blade
contacts an object that it does not immediately cut.
Blade thrust can be violent enough to cause the unit
and/or operator to be propelled in any direction , and
possibly lose control of the unit. Blade thrust can
occur without warning if the blade snags, stalls or
binds. This is more likely to occur in areas where it is
difficult to see the material being cut.
• For operation with the brush blade, do not cut
anything thicker than 1/2 inch or a violent kickback
could occur.
• Do not attempt to touch or stop the blade when it is
rotating.
• A coasting blade can cause injury while it continues to
spin after the engine is stopped or the throttle trigger
is released. Maintain proper control until the blade has
completely stopped rotating.
• Do not run the unit at high speed when not cutting.
• If you strike or become entangled with a foreign
object, stop the engine immediately and check for
damage. Have any damage repaired before attempting
further operations. Do not operate unit with a bent,
cracked or dull blade. Discard blades that are bent,
warped, cracked or broken.
• Do not sharpen the cutting blade. Sharpening the blade
can cause the blade tip to break off while in use. This can
result in severe personal injury. Replace the blade.
• Do not use the cutting blade for edging or as an
edger, severe personal injury to yourself or others can
occur. Use the cutting blade only for the purpose as
described in this manual.
• Stop the engine IMMEDIATELY if you feel excessive
vibration. Vibration is a sign of trouble. Inspect thoroughly
for loose nuts, bolts or damage before continuing. Repair
or replace affected parts as necessary.
After Use
• Clean cutting blades with a household cleaner to
remove any gum buildup. Oil the blade with machine
oil to prevent rust.
• Lock up and store the cutting blade in an appropriate area
to protect the blade from unauthorized use or damage.
