•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.
•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.
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.
•Do not operate the charger with a damaged cord or plug.
•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.
•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.
•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.
•NEVER attempt to connect 2 chargers together.
•The charger is designed to operate on standard 120V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the vehicular charger.
WARNING: Shock hazard. Do not allow any liquid to get inside the charger. Electric shock may
result.
WARNING: 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.
CAUTION: Burn hazard. To reduce the risk of injury, charge only YEEFERM rechargeable
battery packs. Other types of batteries may overheat and burst resulting in personal injury and
property damage.
NOTICE: 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.
