The vent also opens toward the front or toward the rear. This can be
used for forcing air into the cab (open toward the front) or for venting air
out of the cab (open toward the rear).
The vent should not be used during rain, while
washing the vehicle or other circumstances where
water may enter the cab while the vent is open. To
prevent leaks, make sure the handle rollers are on the
top center part of the cams.
Earlier production versions of the VN 780 are equipped with four
hinged side windows in the sleeper area. Later production versions
have two hinged side windows in the sleeper area and two upper vent
windows.
Earlier production versions of the VN 670 have only the two upper
windows. Later production versions have two upper vent windows.
