RULES FOR SAFE OPERATION

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 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.

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.

OTHER SAFETY WARNINGS

Never store the unit, with fuel in the tank, inside a building where fumes may reach an 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 locked up and dry, or high and dry place to prevent unauthorized use or damage. Keep out of the reach of children.

Never douse or squirt the unit with water or any other liquid. Keep handles dry, clean and free from debris. Clean after each use, see Cleaning and Storage instructions.

Keep these instructions. Refer to them often and use them to instruct other users. If you loan someone this unit, also loan them these instructions.

SAVE THESE INSTRUCTIONS

WARNING: The operation of any power tool can cause foreign objects to be thrown into your eyes. This can lead to severe eye damage. Before commencing power tool operation, always wear safety glasses or goggles that are marked as meeting ANSI Z87.1-1989 standards, and a full face shield when needed.
