GENERAL SAFETY RULES

WARNING! Read all instructions
Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains operated (corded) power tool and battery operated (cordless) power tool.

SAVE THESE INSTRUCTIONS
Work Area Safety

Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.
Power tools create sparks which may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.

Electrical Safety

Power tool plugs must match the outlet. Never modify the plug in any way.
Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of electric shock.

[Battery Charger]
Charging Common Cautions for the Liion/NiCd Battery Pack

NOTE:

When a cold battery (of about 0°C or less) is to be charged in a warm room, leave the battery in the room for at least one hour and charge it when it has warmed up to room temperature. (Failing to do so may result in less than a full charge.)
Cool down the charger when charging more than two battery packs consecutively.
Do not insert your fingers into contact hole, when holding charger or any other occasions.

CAUTION:
To prevent the risk of fire or damage to the battery charger

Do not use power source from an engine generator.
Do not cover vent holes on the charger and the battery pack.
Unplug the charger when not in use.

Liion Battery Pack
NOTE:
Your battery pack is not fully charged at the time of purchase. Be sure to charge the battery before use.

Battery charger (EY0L10)

Plug the charger into the AC outlet.
NOTE:
Sparks may be produced when the plug is inserted into the AC power supply, but this is not a problem in terms of safety.
Slide the battery dock cover back to allow insertion of the Li-ion battery pack.
- Verify that the cover is locked securely in place.
Insert the battery pack firmly into the charger.
During charging, the charging lamp will be lit. When charging is completed, an internal electronic switch will automatically be triggered to prevent overcharging.
- Charging will not start if the battery pack is warm (for example, immediately after heavy-duty operation). The orange standby lamp will be flashing until the battery cools down. Charging will then begin automatically.
  The charge lamp (green) will flash slowly once the battery is approximately 80% charged. 6. When charging is completed, the charging lamp will start flashing quickly in green color.
If the temperature of the battery pack is 0°C or less, charging takes longer to fully charge the battery pack than the standard charging time. Even when the battery is fully charged, it will have approximately 50% of the power of a fully charged battery at normal operating temperature.
If the power lamp does not light immediately after the charger is plugged in, or if after the standard charging time the charging lamp does not flash quickly in green, consult an authorized dealer.
If a fully charged battery pack is inserted into the charger again, the charging lamp lights up. After several minutes, the charging lamp may flash quickly to indicate the charging is completed.
