with a clean cloth moistened with a mild 
soap solution. Never use harsh cleaners 
or solvents.

and dirt from the bar groove when

BATTERY PACK
IMPORTANT: THERE ARE NO USER 
SERVICEABLE PARTS INSIDE 
THE BATTERY PACK. DO NOT 
DISASSEMBLE. 
Lithium ion batteries have a finite 
operating life. If the amount of cutting 
time per charge decreases noticeably, the 
battery pack is at the end of its useful life 
and should be replaced. 
• Make sure the battery pack, including 
the contacts, is clean, dry, and has no 
signs of puncture, impact, or other 
damage. Broken batteries can cause 
fires or emit hazardous chemicals. 
• Clean dirty contacts with a soft, dry cloth. 
Dirt or oil can cause a poor electrical 
connection, resulting in loss of power. 
CHARGER
• Unplug the charger from the electrical 
outlet. 
• Clean dirty contacts with a soft, dry 
cloth.
