WARNING: Improperly installed trimmer attachments can create a risk of personal injury to the trimmer operator or bystanders. Improperly installed attachments can work loose and be thrown off the trimmer. In some cases, mounting bolts may not securely fit all intended trimmer models, for example: there may be a difference in the size of the bolt’s counterbore versus the counterbore on the trimmer. Do not install any attachment on any trimmer without a solid, secure fit of all parts.
ATTENTION DEALERS: Install heads only on trimmers that are within the size range (cc displacement or horsepower) for which the head is intended. Performance will suffer if the type of head and the size of trimmer are not properly matched. Read and follow all of the Important Safety Information.
