To adjust the VX
1. Align the correct slot (A or B) on the outer VX
blower tube with the tab (C) on the inner tube. (Fig.
34)
Note: You cannot see the tab when the tubes are
assembled. You must feel the position of the tab as
you move the outer tube.
Note: Engage the tab in position "A" for a large
blower opening. A large blower opening moves wide
areas of dry leaves and other unwanted material.
Engage the tab in position "B" for a small blower
opening. A small blower opening makes air flow
faster to clean cracks and edging and to move heavy
material such as wet leaves.
2. Turn the outer tube as shown to disengage the tab
from the slot. (Fig. 35)
3. Move the outer tube along the inner tube to change
the position. (Fig. 36)
4. Turn the outer tube as shown until the tab is fully
engaged at the end of the correct slot location. (Fig.
