Electric Jack System - Nucamp Cirrus 620 2021 Owner's Manual

• Always use your running lights to increase your visibility to other traffic.
• Never drive under the influence of alcohol, drugs or any kind of medication that will affect your
reflexes, comprehension, and alertness.
• Never drive when you are tired. If you begin to fight sleep, switch drivers or, if you are alone,
find a place to sleep until you are rested enough to go on. It is more important to arrive safe than
on time.
• Never use cruise control on wet, icy roads, winding roads or when traversing
mountainous territory.

ELECTRIC JACK SYSTEM

Important information for proper and safe operation of the camper jacks:
• Electric jacks need 12-volt battery power to operate. If the battery is too low to
operate the jacks, charge the battery before using the jack system. If the camper is on the
truck, starting the truck's engine will supply 12V power to the jacks if the 7-way electrical power
cord is connected.
• If no 12V power is available or battery power is too low to operate the jack system, switch the
power "OFF" to the receiver. This will eliminate the dynamic braking effect of the motor.
Remove the access cap on the top of the powerhead. The crank shaft of the gearbox will be
accessible to turn with a 3/8" ratchet wrench. Rotate the wrench counter-clockwise to raise
the jack and clockwise to lower the jack.
a. Do not activate the motor with the wrench still on the crank shaft.
b. Do not use the electric jacks to raise or lower the camper using only 110V power. The
converter's charger will be damaged if the jacks are operated with 110V power through the 12V
converter without a 12V battery installed in the camper.
• There are two remotes for the jacks. If the remote battery dies, simply plug it into the remote
cable port on the activation switch panel with provided cable. If the black remote does not work,
there is a backup remote on the jack's fuse panel.
• The hand held remote control operates on radio frequency, much like remote units for garage
door openers. The remote is powered by a battery located under the removable cover on the
back of the remote unit. The remote has a range of up to 20 feet from the camper. Occasional
frequency interference from other nearby remote control devices may occur. This should only
result in momentary pauses during the extend or retract operation.
• When operating the jacks with a low 12V battery, the 'all jacks' extend and retract feature may
not work. In that case, use the individual jack buttons to operate the jack.
• When operating the jacks by remote control, visually inspect all four jacks to ensure that they are
responding properly and that you are following proper lifting or lowering camper procedures.
• DO NOT over-extend or over-retract the jacks. The electric jack has an internal slip clutch to help
prevent damage. If a clicking sound is heard, release switch. Continuing to hold the switch will
cause undue wear on the slip clutch and/or cause damage to the motor.
• If the jacks are in operation and no longer respond to the remote, push the control switch and
the light will go out. The jacks should disengage. If they continue to operate, unplug the jack(s)
from their exterior plug and contact your nuCamp dealer for servicing.
• Keep a spare battery available for your remote control for best wireless performance. It is
recommended that you install a new battery in the remote at the beginning of each season (one
per year).
