Latch Adjustment:
should close easily with a comfortable "click". If they are too
loose or if they need excessive pressure to close, they can
be adjusted by turning the latch on the pivoting, threaded
shaft.
Adjust only one turn at a time.
amount of threaded shaft visible (by turning clockwise) will
loosen it. Overtightening the latches will not improve
effectiveness of the vacuum seal and will cause the latches
to wear out prematurely.
Hinge Adjustment: The hinges at the rear of the press are
designed so that they can be easily adjusted to ensure a
good vacuum seal. Make sure that both hinges are adjusted
by the same amount to keep the press lid level. The top part
of the hinge is bolted to the top frame and cannot be moved.
Adjustment is carried out on the bottom part of the hinge.
Both bolts pass through elongated holes in the frame. Should
it become apparent that the grey sealing gasket is not in
contact with the underside of the lid across the entire back of
the press, the adjustment procedure is as follows: Close the
press; loosen both bolts "A" half a turn. Turn on the vacuum
pump. Using a wrench, turn bolt "B" on each hinge a little at a
time until a vacuum is pulled. Only a small adjustment will be
required. Re-tighten both bolts "A".
Vacuum Pump: The vacuum pump is built with sealed, permanently lubricated bearings and does
not require lubrication or other periodic maintenance other than cleaning the filter and water trap.
VACUUM TROUBLESHOOTING
The vacuum gauge should indicate approximately 25" of mercury during normal operation. If the
reading is too low, or the press takes a long time to "pull a vacuum", check for one or more of the
following common problems:
1. Foam or other materials trapped in the seal:
It is very easy for the foam overlay blanket to
become misplaced and inadvertently become
trapped in the seal. This will allow air to leak in,
preventing a good vacuum from forming. Foam
used in the press will tend to expand over time.
As this happens, you should lay it on the bench
and trim a strip off each edge. Also check for
paper, canvas or other materials that may be
stuck to the lid and interfering with the seal.
2. Press is not level: If all four corners of the
press are not level, it may be difficult to achieve
a proper vacuum. Use a carpenter's (bubble)
level to verify. If one corner is out of alignment, use shims under the press as necessary to
correct.
