• 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.
• This Class B digital apparatus complies with Canadian ICES-003.
• This device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions:
1) This device may not cause harmful interference, and
2) This device must accept any interference received, including
interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which
can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of
the following measures:
– Reorient or relocate the receiving antenna.
