• Avoid accidental starting. Be in the starting position whenever pulling
the starter rope. The operator and unit must be in a stable position
while starting. Refer to Starting/Stopping Instructions.
• Use the right tool. Only use this tool for its intended purpose.
• Do not overreach. Always keep proper footing and balance.
• Always hold the unit with both hands when operating. Keep a firm grip
on both handles or grips.
• Keep hands, face, and feet at a distance from all moving parts. Do not
touch or try to stop the cutting attachment when it rotates.
• Do not touch the engine, gear housing or muffler. These parts get
extremely hot from operation, even after the unit is turned off.
• Do not operate the engine faster than the speed needed to cut, trim or
edge. Do not run the engine at high speed when not cutting.
• Always stop the engine when cutting is delayed or when walking from
one cutting location to another.
• If you strike or become entangled with a foreign object, stop the engine
immediately and check for damage. Do not operate before repairing
damage. Do not operate the unit with loose or damaged parts.
• Stop the unit, switch the engine to off, and disconnect the spark plug
for maintenance or repair.
• Use only original equipment manufacturer replacement parts and
accessories for this unit. These are available from your authorized
service dealer. Use of any unauthorized parts or accessories could
lead to serious injury to the user, or damage to the unit, and void your
warranty.
• Keep unit clean of vegetation and other materials. They may become
lodged between the cutting attachment and shield.
• 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 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 when the cutting blade is 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
propel the unit and/or operator in any direction, possibly causing a
loss of control. 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 may incur. Use the cutting blade
only for the purpose 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.
RULES FOR SAFE OPERATION
• Lock up and store the cutting blade in an appropriate area to protect
the blade from unauthorized use or damage.
OTHER SAFETY WARNINGS

open flame or spark.
• Allow the engine to cool before storing or transporting. Be sure to
secure the unit while transporting.
• Store the unit in a dry area, locked up or up high to prevent
unauthorized use or damage, out of the reach of children.
