Nano: Manual Shade Box - Adjusting the Spring Tension

---

---

The spring tension must be set, in order to adjust the speed of the shade. The amount of pre-tensions required for each shade varies and can be found on the attached shade list.

---

Step 1: Adjusting the Tension

• Pull the shade down a small amount (~1/2”) and release.
• The shade will run to the upper limit.

---

Step 2: Adjusting the Tension

• Unlock and lever the front cassette up, removing it from the back cassette.

---

Step 3: Adjusting the Tension

• Install the pretension tool into the 2 slots on the head of the motor (Right side for standard roll, Left side for reverse roll).
• Gently slide the head up and then pull away from the end cap to release.

• If the shade moves too slow, add one pre-tension turn at a time until the desired speed is achieved.

• If the shade moves too fast, reduce one pre-tension turn at a time until the desired speed is achieved.

---

Step 4: Adjusting the Tension

• Re-install the roll into the bracket and test the tension
• If more tension is needed, repeat Step 3

---

If the motor lost all tension, use this chart based on the size of your shade to add the minimum amount of tension.

• 1 click is approximately 1/4 turn, each number on the chart equals 1 click (1/4 turn)
