Power Jack Fuse
Should an electrical failure occur, remove the power
head by loosening the two Allen setscrews The jack
post may now be operated manually by inserting the
emergency handle into the coupling on top of the post
Refer to the Maintenance section for replacement and

Operating Instructions
1
To open - slide forward and pull up to open latch
before inserting ball
2
Place coupler on ball of same diameter as coupler
and of same or greater capacity
3
When ball is completely nested in socket, push
top of latch handle rearward until handle snaps
into closed position Extend jack to ground and lift
tow vehicle/trailer combination 2 to 4 in to ensure
coupler is securely attached to tow ball Retract
jack before towing
4
Insert padlock through hole in handle for theft-
prevention purposes
Always open latch handle before inserting ball into
coupler.

WARNING
Liquid Petroleum Gas (LPG)
Fill Valve
The LPG tanks are equipped with fill valve connections
RV Type I Acme The large, green, nylon swivel nut is
a right-hand thread and is designed for hand operation
only
The valve features an internal spring-loaded module
that will not allow gas to flow from the cylinder until a
positive seal has been made at the connection The
valve outlet has 1-5/16 in Acme threads on the outlet
exterior, and female POL fitting; left-handed threads
on its interior This feature allows for connection of the
new, wrench less, right-handed, Acme RV connection
while still accommodating the standard left-handed
POL fittings used for filling propane cylinders.
The mating, green swivel nut and brass nipple also
incorporate new features: the green nylon nut swivels
on a black bushing that is heat-sensitive Between 240
and 300°F, the bushing will yield (melt) allowing the
spring-loaded module in the valve to push the brass
nipple back (approximately 1/4 in ), closing the module
and stopping the flow of gas from the cylinder. Inside
the brass nipple is a flow-limiting device designed
to sense excessive gas flow. If an excessive flow is
sensed, the flow-limiting device shuts the flow down
to a maximum of 10 SCFH (Standard Cubic Feet per
Hour) or less This is also referred to as the bypass
flow.
Bypass flow is extremely important in the proper
operation of this connection. The flow-limiting device
may activate if the cylinder valve is opened quickly
When all appliances are off, the bypass flow allows
the pressure downstream from the flow-limiting device
to equalize. When pressure is equalized, the flow-
limiting device will supply normal flow to the system.
Equalization occurs in approximately 5 seconds and,
in most cases, goes completely unnoticed If, however,
an appliance is left on or there is a leak or open flow
in the system, the bypass pressure will not be able to
equalize and allow the flow-limiting device to re-open.
