REPAIRS
2. Make sure vacuum pump is not plugged in.
3. Remove the oil drain cap and drain the contaminated oil into
a suitable container. Tilt the vacuum pump toward the oil drain
port.
4. Once all the oil has been drained, re-secure the oil drain cap
back onto the oil drain port.
5. Remove the exhaust/oil fi ll cap and add oil until it is seen in the
middle of the oil sight glass. Re-secure exhaust/oil fi ll cap.
LID REALIGNMENT
NOTE: The vacuum is sealed under the lid by means of rubber
gasket under the lid frame. This rubber gasket may compress
over time. If the vacuum does not occur, the rubber gasket may
be compressed. These problems can be alleviated by lowering
the hinges.
CAUTION: It is important to do this operation with the lid up, failing
to do so could cause injury due to the sudden release of pres-
sure on the gas spring!
1. Fully open the lid.
2. Using a pencil, tape, or other suitable indicator, place a mark on
the frame of the unit corresponding with a mark on the lower leaf
of the hinges.
3. Using a 9/16” wrench, loosen the four bolts fastening the lower
leaf of the hinges.
4. Let each hinge drop approximately 1/16” using the
indicator placed on the hinge in step 2.
5. Tighten all four bolts securely and test unit. If this does not work
repeat this process and drop the hinges another
1/16”
Warning: Lowering the hinges too much can place excess pressure
on the glass and frame of the unit and should be avoided. If
the lid is diffi cult to close or does not stay closed under it’s own
weight, the hinges should be raised.
NOTE: If the blanket fails to pull a vacuum, check the Troubleshoot-
ing Chart for possible causes. If you determine that your blanket
has begun to leak, it needs to be replaced. New blanket material
can be ordered from HIX Corporation.
