hazard Symbols and meanings

11. It is advisable to wear protective headgear to 

prevent the possibility of being struck by small flying 
particles, or being struck by low hanging branches, 
twigs, or other objects which may be unnoticed by 
the operator.

1. Do not operate the trimmer without proper guard or 

other safety protective devices in place.

13. Use this equipment for its intended purpose only.
14. See manufacturer’s instructions for proper operation 

and installation of accessories. Only use accessories 
approved by the manufacturer.

15. Operate only in daylight or good artificial light.
16. Do not operate product when fatigued or under 

the influence of alcohol, drugs or other medication 
which can cause drowsiness or affect your ability to 
operate this machine safely. 

17. Never operate trimmer in wet grass. Always be sure 

of your footing; keep a firm hold on the handle and 
walk; never run.

18. Before each use, inspect the throttle control lever 

and cable. Make sure that the cable is free and that 
the lever is not damaged. Also check the cable 
linkage running to the carburetor for kinks, loose 
fittings, and obstructions. Verify that the control bail 
is working properly.

19. Stop the rotating trimmer head when crossing gravel 

drives, walks, or roads. Wait for the cutting lines to 
stop rotating. 

0. Watch for traffic when operating near, or when  

crossing roads.

1. Stop the engine (motor) whenever you leave the 

equipment, before cleaning, repairing or inspecting 
the unit, be sure the trimmer head and all moving 
parts have stopped. Let the engine cool, disconnect 
the spark plug wire and move it away from the spark 
plug.

. If the equipment should start to vibrate abnormally, 

stop the engine (motor), disconnect the spark plug 
wire and prevent it from touching the spark plug. 
Check immediately for cause. Vibration is generally a 
warning of trouble.

3. After striking a foreign object, stop the engine (mo-

tor). Remove the wire from the spark plug. Inspect 
the trimmer for damage. If damaged, repair before 
starting and operating the trimmer.

4. Never leave the trimmer unattended when the 

engine is running. Remove the wire from the spark 
plug.

5. Regularly inspect the trimmer. Make sure parts are 

not bent, damaged or loose. 

6. Allow muffler and engine areas to cool before 

touching. Never pick up or carry the trimmer while 
the engine is running. 

7. Prolonged exposure to noise and vibration from 

gasoline engine powered equipment should be 
avoided. Take intermittent breaks and/or wear ear 
protection from engine noise as well as heavy work 
gloves to reduce vibration in the hands.
