MAINTENANCE AND REPAIR INSTRUCTIONS

IMPORTANT!

LUBRICATING CAMS

The cams are lubricated with a sufficient amount of high-
temperature grease. To keep the attachment operating
efficiently, apply a high-temperature grease to the cams,
and in between the yokes every 6 hours of use. (Fig. 7)
WARNING: Failure to apply high-temperature
grease every 6 hours of operation can result in
failure of cams and blade, and will void your
warranty.

BLADE REPLACEMENT

NOTE: We recommend that you take the hedge trimmer
attachment to your nearest authorized service
dealer to replace the blade.
NOTE: Disconnect the hedge trimmer attachment from
the powerhead before replacing the blade.
REMOVING BLADE

blade assembly, do not place your hand or
fingers between blades or in any position
where they could get pinched or cut.
