Adjustments
Note:
The Ultra Vac QDS was adjusted at the factory to operate properly. However, there are three basic
adjustments that can be made, should your unit require them:
1. Fill sensors: Located inside the hopper, they
sound an alarm when the hopper is full. They can
be adjusted for varying grass conditions that fill
the hopper differently (see Figure 11).

Moving the LH sensor up works better in wetter
conditions.
Moving the LH sensor down works better in
dryer conditions.
2. Latches: The latches (Figure 12) can be adjusted.
With the door closed, the latch plate should be
set so that the latch cams completely engage and
contact the latch plates bolted to the door.

2. Whizlock nuts
3. Latch handle link: The latch handle needs to be
able to snap over-center to keep the latch cams
tight against the door latch plates and the door
pulled shut. The length of the latch linkage is
controlled by the two whizlock nuts on either side
of the latch link (Figure 12). The whizlock nuts
should be adjusted so that reasonable force on
the handle is required to over-center and latch
the door. Do Not adjust so that the over-center
spring collapses completely when the door is fully
latched.
