7. When operating a charger outdoors, always provide a dry
location and use an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces the risk of
electric shock.
8. An extension cord must have adequate wire size (AWG or
American Wire Gauge) for safety. The smaller the gauge
number of the wire, the greater the capacity of the cable, that
is, 16 gauge has more capacity than 18 gauge. An undersized
cord will cause a drop in line voltage resulting in loss of power
and overheating. When using more than one extension to
make up the total length, be sure each individual extension
contains at least the minimum wire size. The following table
shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier
gauge. The lower the gauge number, the heavier the cord.

9. Do not place any object on top of the charger or place the
charger on a soft surface that might block the ventilation
slots and result in excessive internal heat. Place the charger
in a position away from any heat source. The charger is
ventilated through slots in the top and the bottom of the
housing.
10. Do not operate the charger with a damaged cord or plug -
have them replaced immediately.
11. Do not operate the charger if it has received a sharp blow,
been dropped or otherwise damaged in any way. Take it to an
authorized service center.
12. Do not disassemble the charger; take it to an authorized
service center when service or repair is required. Incorrect
reassembly may result in a risk of electric shock, electrocution
or fire.
13. Disconnect the charger from the outlet before attempting
any cleaning. This will reduce the risk of electric shock.
Removing the battery pack will not reduce this risk.
14. NEVER attempt to connect two (2) chargers together.
15. The charger is designed to operate on standard 120V
household electrical power. Do not attempt to use it on any
other voltage.

Shock hazard. Do not allow any liquid to get inside the
charger. Electric shock may result.
Burn hazard. Do not submerge the battery pack in any
liquid or allow any liquid to enter the battery pack. Never
attempt to open the battery pack for any reason. If the
plastic housing of the battery pack breaks or cracks,
return to a service center for recycling.
Burn hazard. To reduce the risk of injury, charge only
original manufacturer rechargeable battery packs. Other
types of batteries may overheat and burst resulting in
personal injury and property damage.
Under certain conditions, with the charger plugged into
the power supply, the charger can be shorted by foreign
material. Foreign materials of a conductive nature, such
as, but not limited to, grinding dust, metal chips, steel
wool, aluminum foil or any buildup of metallic particles
should be kept away from the charger cavities. Always
unplug the charger from the power supply when there is
no battery pack in the cavity. Unplug the charger before
attempting to clean.
