volts alternating current) into 12 volts direct
current.
Do not assume that a shore power supply is
correctly wired. Shore power may have incorrect
polarity or not have the safety ground. Before
connecting your trailer, test shore power by using a
polarity and ground tester, which can be purchased
at electronic stores.
If you have shore power, your trailer may be fitted
with Ground-Fault Interrupting outlets (GFI). If
you have GFI protection, you must periodically test
the outlets by pressing the “TEST” button that is
located on the GFI-equipped outlet.
^ WARNING
Shore power poses a risk of death due to
electrocution.
Always use a grounded connection.
Never connect to an ungrounded source of
shore power.
Never remove the “third prong” from the
shore power plug.
^ WARNING
Risk of fire.
Connect only to source of correct voltage.
Do not overload electrical circuits.
Do not use an extension cord to connect to
shore power.
Replace fuses with like rating.

EAR
Your Featherlite coach trailer has an electric
powered landing gear (also known as a “jack”) for
raising and lowering the tongue and coupler.
The landing gear is operated up or down using a
control pendant plugged into a socket located near
the landing gear.
The motion of the landing gear is accomplished
either with a hydraulic system or a mechanical
system.
7.4.1 Electric-Powered Hydraulic Jack
An electric-powered hydraulic jack uses an electric
motor to operate a pump, and the pressure from the
pump is used to extend or retract a hydraulic
cylinder. There is no way to manually extend or
retract the jack leg(s) of an electric-powered
hydraulic landing gear.
7.4.2 Electric-Powered Mechanical Jack
An electric-powered mechanical jack uses an
electric motor operating through a gear transmission
to turn a jack screw.
If the electric motor does not operate, such as when
the battery is fully discharged, an electric-powered
mechanical landing gear can be operated manually
with a crank. See Figure 7-1.

POWERED LIFT
Your Featherlite coach trailer has an electric-
powered lift for raising cargo to permit additional
loading. The lift is operated using a control pendant
plugged into a socket near the lift.
The motion of the lift is accomplished with a
hydraulic pump that operates either a set of jack
screws, or a cable assembly.
7.5.1 Electric-Powered Jack-Screw Lift
An electric-powered jack screw lift uses an electric
motor to operate a pump, and the pressure from the
pump operates hydraulic motors that turn
mechanical jack screws. The jack-screw type of lift
is self-blocking.
