Debris Blower Rotation Pinions
The two (2) rotation pinions should slightly contact
each other without any resistance.
1. Loosen the set screw of each stop ring on the
rotation handle.
2. Keeping the two (2) pinions slightly in contact
with each other, position the upper stop ring
against the lower support and tighten the screw.
3. Position the lower stop ring close to the lower
support and tighten the set screw. The rotation
handle should rotate freely without excessive
end play.
Debris Blower Rotation Handle
With the rotation pinions properly adjusted, the two
(2) stop rings should be positioned close enough to
the lower support to allow the rotation handle to ro-
tate freely without excessive end play.
