Reverse button for debris removal
WARNING:
• Switch off the tool and remove the battery cartridge
before you remove entangled weeds or debris
which the reverse rotation function can not

short period of time and then automatically stops.
• Once the tool is stopped, the rotation returns to regular
direction when you start the tool again.
• If you tap the reverse button while the tool's head is still
rotating, the tool comes to stop and to be ready for
reverse rotation.
