Check for alignment of moving parts, binding of moving parts, breakage of parts, damaged mountings, and any other condition that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless indicated elsewhere in this manual.
• Remove or disconnect battery before servicing, cleaning or removing material from the gardening appliance.
• Do not modify or attempt to repair the appliance or the battery pack (as applicable) except as indicated in the instructions for use and care.
