3.7 ADJUSTMENTS:
Your 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:
3.7.1
Door closing:
The closing of the door is controlled by the two hinge links (Figure
13 – A) and the two stop screws (Figure 13 – B). 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.
3.7.2
Door opening:
After adjusting the hinge links for door closing, the handle link
(Figure 13 – C) can be adjusted to obtain maximum door opening. 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 (Figure 13
– D). This stop is non adjustable, and prevents over opening damage from
occurring to the linkage.
3.7.3
Latches:
Once the open and closed positions have been set, the latches (Figure 13
– E) can be adjusted. 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”.
