Use and Care Manual
2
Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes in contact
with your skin, wash immediately with soap and water. If liquid gets into your eyes, flush them with
clean water for at least 10 minutes, then seek immediate medical attention. Following this rule will reduce
the risk of serious personal injury.
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.
Always remove battery pack from your tool when you are assembling parts, making adjustments,
cleaning, or when not in use. Removing battery pack will prevent accidental starting that could cause serious
personal injury.
Always remove battery pack before storing the device.
When battery becomes fully charged, unplug the charger from the power supply and remove the battery
pack from the charger.
Always wear eye protection with side shields marked to comply with ANSI Z87.1. Failure to do so could
result in objects being thrown into your eyes and other possible serious injuries.
Keep battery pack dry, clean, and free from oil and grease. Always use a clean cloth when cleaning. Never
use brake fluids, gasoline, petroleum-based products, or any solvents to clean battery pack.
Do not use a battery pack that is damaged or modified. Damaged or modified batteries may exhibit un-
predictable behavior resulting in fire, explosion or risk of injury.
Do not modify or attempt to repair a battery pack that has been damaged.
Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature
above 265°F may cause explosion.
Have servicing performed by a qualified repair person using only identical replacement parts. This will
ensure that the safety of the product is maintained.
Save these instructions. Refer to them frequently and use them to instruct others who may use this tool. If
you loan someone this tool, loan them these instructions also.
OPERATION
LITHIUM-ION BATTERY PACKS
Lithium-ion batteries deliver fade free power for their entire run time. Lithium-ion tools will not gradually lose
power due to decreasing battery charge. Instead, power from the battery pack will drop from full to zero once
the full charge has been drained from the battery. Once this happens, recharging of the battery is required. It is
not necessary to drain the battery pack completely before recharging.
BATTERY PROTECTION FEATURES
Lithium-ion battery packs are designed with features that protect the lithium-ion cells and maximize battery life.
If the tool stops during use, release the trigger to reset and resume operation. If the tool still does not work, the
battery may be too hot or may need to be recharged. Allow it to cool or place it on a charger.
COLD WEATHER OPERATION
The lithium-ion battery pack can be used in temperatures down to – 4°F. Put the battery pack on a tool and use
the tool in a light duty application. After about a minute, the pack will warm up and begin operating normally.

CHARGING THE BATTERY PACK
Battery packs are shipped in a low charge condition to prevent possible problems. Therefore, you should charge
prior to first use. If the charger does not charge the battery pack under normal circumstances, return both the
battery pack and charger to your nearest Authorized Service Center for electrical check.
Charge the battery pack only with the recommended charger.
Refer to charger operator’s manual for charging instructions.
CHARGING A HOT BATTERY PACK
When using a tool continuously, the battery pack may become hot. A hot battery pack may be placed directly
onto the charger port but charging will not begin until the battery temperature cools to within acceptable tem-
perature range. When a hot battery pack is placed on the charger, the charger may indicate the pack is not ready
to charge. Please refer to charger operator’s manual. When the battery pack cools, the charger will automatically
begin charging.
