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:

Handle Link
3.
Stop
5.
Latches
2.
Stop Screws
4.
Hinge Links
1.
Door closing:
The closing of the door is
controlled by the two hinge links and the two stop
screws (see Figure 9). The stop screws should be
adjusted so that both will be contacted when the
contacting arm is straight up and down. With the
stop screws adjusted, the length of the hinge links
can be changed to provide complete closing of
the door, and reasonable force on the handle to
latch or unlatch the door. Lengthen the links to
reduce the force. Shorten the links to increase the
force. With the door closed, both links should be
slightly tight to minimize rattling.
2.
Door opening:
After adjusting the hinge
links for door closing, the handle link can be
adjusted to obtain maximum door opening (see
Figure 9). Lengthen the link to open the door
farther. Shorten the link to open the door less.
The maximum door opening is limited by the
contacting arm hitting the stop. This stop is non
adjustable, and prevents over opening damage
from occurring to the linkage.
3.
Latches:
Once the open and closed positions
have been set, the latches can be adjusted (see
Figure 9). With the door closed, the latch link
should be set so that the latch plate completely
engages and contacts the latch rod welded to the
door. The latch plates should not be tight against
the latch rod. They should easily “wiggle”.
