4-6 Awning Operation

~ 4-6-4 ~ Rev. “C”
Partial Extension or “Caravan” Position
Follow Step 1 on previous page.
Insert the pull rod in the loop of the center control strap and unroll the awning to
the desired extension.
To prevent billowing, release and raise the rafter arm ( Fig. 10 ) and hook the
claw of the arm into the slot of the rafter lock ( Fig. 14 ). This will require the
awning to be extended approximately four and one half feet.
Raise the awning to the desired height by following Step 5.

4-6.2.2 Closing
Release the snap stud of the main arm and lower the awning to its bottom most position.
Release the ratchet stud of the rafter arm and lift the claw out of the rafter hook.
Place the claw casting on the protruding height adjustment stud. To lock the assembly in a travel position, push the other
tube downward until the ratchet stud snaps closed. Repeat Steps 1-3 for the other end of the awning.
Face the awning and hold the end of the control strap fi rmly in one hand. Push the roller briskly upward with a rolling
motion until you feel the spring take over. Control the speed of closure by holding the control strap until all but 6 inches
of the fabric has rolled up. Release the strap and let the awning roll freely the rest of the way. This extra force will help
tighten the fabric around the roller to insure the tightest, neatest appearance.
Lock the awning in place by fl ipping the Z-lock lever into the “closed” position using the pull rod.
If Awning Rolls Up Uneven
Observe if the roll-up is even and in line with the clamps (if any). If not, then unroll the awning and give the roller a slight push
towards the direction it should go. If you wish to have the awning roll up more in either direction, then spiral the pull strap in
that direction.
How to Adjust Spring Tension
There is only one spring, located at the rear end of the awning. The winding procedure uses the main arm bar as a lever,
since the spring is connected to the bar through the roller shaft and head casting.

Open the Z-Lock lever(s) carefully and allow the awning to open.
Support awning roller with ladder or with help of assistant.
Disconnect rear main arm from main hinge. Pull outward on snap
stud and slide tube portion off from bar (to shorten arm for winding.)
Stand at the rear of awning facing front of vehicle and grasp main
arm bar. Adjust the spring by winding clockwise to increase tension
or counter-clockwise to decrease tension so that the open awning
will not start to roll up until given a rolling start by hand of about 12
inches. This will eliminate the need to lock the awning open.

NOTE: The strap must be spiraled around the roller. This prevents a loose roll and bunching of the fabric.
WARNING!!
The spring is under tension. Do not disconnect the bar from the head casting. The
weight of the bar is enough to counterbalance the spring tension. Use of any other winding device
could be dangerous if not controlled, resulting in personal injury or property damage.
