Changing (Remove Power) Head Assembly
Resources Required
• 1-3 people (depending on task)
• Cordless or Electric Drill or Screw Gun
• Appropriate Drive Bits
• Zip Ties
Failure to secure the outer arms may result in serious personal injury or property damage. Pressure from
the gas strut can cause the outer arm to kick open, which could cause serious injury or unit damage.
1. Extend the awning about 12" away from the unit.
2. Secure both support arm assemblies by running a zip tie around the outer arm and around the pin on the top
of the mount arm where the mount arm and inner arm connect (Fig. 4).
3. Remove the wax screw from the end cap that attaches to the shaft on the drive head assembly.
4. Support the roll tube to prevent the fabric from pulling out of the awning rail on the side of the unit.
5. Remove the drive head assembly retaining bolt from the outer arm.
6. Disconnect the wires. Remember the orientation of the colored wires.
7. Remove the old drive head assembly from the unit and set aside.
8. Connect the new drive head assembly shaft to the roll tube end cap.
9. Replace the wax screw in the roll tube end cap, securely attaching it to the drive head assembly shaft.
10. Connect the wiring according to the previous color orientation and slide it into the outer arm. Be
careful not to pinch the wiring between the drive head assembly and the outer arm.
11. Secure the drive head assembly in the outer arm with the drive head assembly retaining bolt.
When cutting the zip tie, hold the outer arm so it does not kick open. Pressure from the gas strut can
cause the outer arm to kick open, which could cause serious injury or unit damage.
9. Remove the support arm assembly from the unit. It should be completely free now and can be
removed from the working area.
10. Mount the new support arm assembly to the wall using fasteners similar to those removed from the
old support arm assembly. One fastener will hold the assembly in place at this time.
11. Very carefully cut the zip ties while holding the support arm assembly. The gas strut will force the
support arm assembly to extend. Be cautious and continue to maintain control of the support arm
assembly while slowly allowing it to extend.
Make sure the roll tube is adequately supported before removing the support arm assembly. Failure to
do so may result in serious personal injury or property damage.
12. Install the remaining fasteners. There are six total fasteners: 2 at the top, 2 in the middle and 2 at the
bottom of the support arm assembly (Fig. 2, Fig. 3 and Fig. 5).
13. Push the support arm assembly back toward the unit to align the head assembly with the support arm
assembly. Install the head assembly back into the support arm assembly and secure with the head
assembly retaining bolt.
14. Pull the wires from the unit through the support arm assembly. These wires may be located at the
bottom or the top of the support arm assembly. Use a cordless battery and extend the awning fully.
15. Reconnect all wiring as previously connected.
NOTE: Check the switch. If the awning is running reverse of what the switch indicates, reverse the wires.
16. Seal all areas at this time.
