Battery tools do not have to plugged into an electrical outlet;
therefore, they are always in operating condition. To prevent serious personal injury,
take extra precautions and care when performing maintenance, service, or when
changing the cutting attachment or other attachments.

To prevent serious personal injury, remove the battery pack from the
tool before servicing, cleaning, or removing material from the unit.
All string trimmer service, other than the items listed in these maintenance instructions,
should be performed by competent string trimmer service personnel.
TRIMMER HEAD REPLACEMENT

Replace a cracked, damaged or worn-out cutting head immediately,
even if damage is limited to superficial cracks. Such attachments may shatter at high
speed and cause serious injury.
