• DO NOT use an extension cord unless it is absolutely necessary. Use of improper
extension cord could result in risk of fire, electric shock or electrocution.
• 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 table below 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.
