To ensure safe operation

Operator Responsibility

• Stop the engine with the engine switch to the OFF position in the 

following cases:

– Before any operation around the cutting attachment.

– Before checking, cleaning or working on the grass/weed trimmer.

– After striking a foreign object. Inspect the grass/weed trimmer for 

damage and make repairs before restarting and operating the grass/

weed trimmer again.

– If grass/weed trimmer starts to vibrate abnormally. Check 

immediately the cause of the vibration and perform the necessary 

repair.

– Whenever you leave the grass/weed trimmer unattended.

– Before refueling.

– When any person or pet is approaching.

– Shut off the engine immediately when the grass/weed trimmer 

shows abnormal vibration suddenly. Sudden vibration can suggest 

the damaged rotating parts or loose fasteners. Examine the cause 

of the problem, and do not start the engine before repair is made.

– When wires catch on the wheeling cutting attachment and flap 

around. Remove the wires after the cutting attachment has 

stopped turning.

– Before placing the grass/weed trimmer on the ground, make sure 

the cutting attachment stops turning as well.

Note that the cutting attachment is turning by inertia right after 

returning the throttle trigger and while the engine is idling.

• The grass/weed trimmer is faulty when the engine is idling by 

returning the throttle but the cutting attachment keeps turning, and 

idle speed adjustment must be made. Consult your authorized Honda 

dealer.

• Keep all nuts, bolts and screws tight to be sure the grass/weed 

trimmer is in safe working condition. Regular maintenance is an 

essential aid to user’s safety and retaining a high level of 

performance.
