[Battery Pack] For Appropriate Use of Bat­ tery Pack Li-ion Battery Pack (EY9L40) • For optimum battery life, store the Li-ion battery pack following use without charging it. • The ambient temperature range is between 0°C (32°F) and 40°C (104°F). If the battery pack is used when the battery temperature is below 0°C (32°F), the tool may fail to function properly. • When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause sparks, burns or a fire. • When operating the battery pack, make sure the work place is well ventilated. • When the battery pack is removed from the main body of the tool, replace the battery pack cover immediately in order to prevent dust or dirt from contaminating the battery terminals and causing a short circuit. Excessive (complete) discharging of lithium ion batteries shortens their service life dramatically. The driver includes a battery protection feature designed to prevent excessive discharging of the battery pack. • The battery protection feature activates immediately before the battery loses its charge, causing the battery low warning lamp to flash. • If you notice the battery low warning lamp flashing, charge the battery pack immediately. Battery Pack Life The rechargeable batteries have a limited life. If the operation time becomes extremely short after recharging, replace the battery pack with a new one. -  -
