5.1 Check Line Cord
This maintenance task can be part of the driver’s daily responsibilities.
• Before every use, check the line cord for any damage to the outer jacket.
o Minor chafing or abrasion is acceptable.
o If the jacket is cut or cracked, or if the inner wires are visible, the line cord is unsafe. It
must be replaced and immediately removed from service.
• Check the plug at each end of the line cord and the shore power inlet for signs of arcing. Look
for charred or sooty areas around the electrical contacts. If the male plug prongs have become
burned, pitted, eroded, or otherwise damaged, remove from use. Have an electrician check the
affected connectors; it is likely that both male and female components will need replacement.

• When unplugging the cord, take note if the plug body feels unusually warm. This may indicate
that a connection is becoming loose. If you notice unusual heat, remove the cord from use and
have it checked by an electrician.
WARNING: Though very rare, it is possible for a failed plug to become hot enough to cause burns.
If any electrical device is emitting smoke, has a burning odor, or has plastic parts which are melted or
distorted, do not touch it. Turn off the switch or circuit breaker if safe to do so. Call 911 in case of fire.
