Page 7: Section 4 - Assembly From Broken Down Form
Section 4 - Assembly From Broken Down Form FULL LENGTH SHIPPING FORM: Your EZ2 will probably be shipped to you in a 13 Ft. length configuration. 13 Ft. SHIPPING FORM: If your EZ2 was shipped to you in the 13 Ft. shipping form, you can reassemble your glider to its full length by following these procedures. -
Page 8: Section 5 - Set-Up And Fold Down Procedures
Section 5 - Set-Up And Fold Down Procedures Your EZ2 unique components were designed to set-up in the simplest, most efficient manner. The instructions given below provide you with the step-by-step procedure for setting up your glider. By closely following these instructions, you can assure yourself a smooth, quick set-up. - Page 9 2. FIG. 2: Roll the glider over so that it is the right way up and stand on the control frame. 3. FIG. 3: Remove the cover and all the ties. Carefully walk each wing out to its approximate flying position. AT THIS STAGE IT IS ESSENTIAL TO ENSURE THAT THE KEEL AND LEADING EDGES ARE ALWAYS IN THE SAME PLANE.
- Page 10 5. FIG. 5: Find the cross tube tensioning wire up inside the keel pocket. Then using the black webbing handle pull the cable back to snap into the spring catch. Now you will need to hook up the back top wire into rear spring fitting also.
- Page 11 7. FIG. 6: At this point attach the front flying wires to the nose plate by slipping the ring around the nose spring catch. 8. Install if necessary the nose batten “tail end first” from the nose of the glider seating the front end of the rib on the keel tube just in front of the nose plate.
- Page 12 PREFLIGHT INSPECTION The nature of the EZ2 is such that most of the pre-flight checkpoints common to other flex wings are hidden to eliminate parasitic drag. A thorough pre-flight procedure is mandatory with all aircraft, however, and the best technique is a circular walk around the glider.
- Page 13 FOLD DOWN PROCEDURE To fold down your EZ2, just reverse the set-up procedure steps as described above. Included here are a few guidelines to follow which will save you time and prevent wear areas on your sail: 1. IMPORTANT: While setting up or relieving the EZ2's cross tubes and airfoil from tension, the rear of the keel must remain on the ground at all times! 2.

Page 14: Section 6 - Flying Techniques
Section 6 - Flying Techniques TAKE OFF The EZ2 has a neutral static balance and is very easy to launch in both calm and windy conditions. When you hold the glider prior to your take off run, you should have the nose slightly elevated and the wings level. AGAIN MAKE SURE THAT YOU ARE HOOKED IN! Run hard and ease the bar out for lift-off. - Page 15 push out harder, the nose of the glider will come up a little bit higher. A gentle pitch down will follow this and the glider will regain flying speed. There is not a lot of altitude lost in the type of maneuver. Never stall your glider completely with the nose pitched-up very high.

Page 18: Section 8 - Tuning And Troubleshooting
If, however, you have any questions, please contact your authorized North Wing dealer. If any adjustments are made on your glider, we recommend that they be noted in your Maintenance Log (Section 12 of this manual). It is then easy to go back and trace occasional problems. - Page 19 TROUBLESHOOTING CHART KEY KEY ACTION Check for proper assembly, twisted thimbles. Crossbar setup cable not fouled on kingpost bolts. All ribs secured, check for proper position of trailing edge lines. Match all ribs to the airfoil maintenance blueprint provided with your EZ2 Move hang strap back (1/2”...
- Page 20 * To modify leading edge tension, slip the tip webbing off the swivel tip plug and slide the sail forward. You will see that the swivel plug is kept from sliding into the leading edge by a clevis pin mounted in one of a series of holes in the aft leading edge.
- Page 21 Changing the main cross spar tension actually changes the nose angle and the anhedral of the glider. Increasing the nose angle WILL NOT necessarily increase the performance. In fact, over-tightening the main cross spar tension can deteriorate the sink rate with no advantage at high speeds. However, slackening the cross spar tension does make the handling lighter.

Page 22: Section 9 - Maintenance Schedule
Section 9 - Maintenance Schedule Your new EZ2 will require very little in the way of maintenance if you care for it properly in your everyday use. Here are some general points to follow in maintaining your new EZ2 which will help ensure the safety of your flying and the performance retention of your glider. - Page 23 SAIL 1. If you must wash the sail, wash it with a light detergent only. Better still, wipe the sail down frequently with a soft, damp cloth and that will keep detergent washing to a minimum. 2. Acetone or alcohol can be used to remove stubborn stains without harming the sail.
- Page 24 HARDWARE AND BOLTS 1. For all practical purposes, North Wing hardware is indestructible in hang gliding (flight) applications. “AN” bolts, however, are not indestructible and bending them even in light crashes is common. Check them periodically to be safe.

Page 28: Section 11 - Glider Disassembly
Section 11 - Glider Disassembly PREPARATION In order to best perform this operation, you must first place your glider “right side up” on two saw horses located 3 feet from both ends, with all ties removed and with the leading edge spread approx. 1 ft apart. You can actually perform the same operation on a clean floor or lawn. - Page 29 A FEW LAST WORDS Your North Wing EZ2 is a sophisticated high performance hang glider, that will give you years of safe and enjoyable soaring, provided that you treat it properly and always maintain a healthy respect for the demands and potential dangers of flying.
