Installation
1. Clean the mounting surface and, if needed,
the face of the vacuum cup (see cleaning).
2. Position the cup on the mounting surface so
the plunger is accessible and visible to the
operator.
3. Pump the plunger until the cup attaches
completely. When the red line on the plunger
is hidden, the cup is ready for use.
4. Check the plunger frequently to make sure
the cup remains securely attached. If the red
line appears, pump the plunger until the red
line is hidden again.
Release
1. Grasp and hold the joystick and cup assem-
bly.
2. Pull one of the release tabs until the cup
disengages completely.
Remove the cup when not in use. If the cup
remains attached to a hot surface (e.g,. in direct
sunlight) for an extended period, the rubber pad
could bond to the mounting surface, resulting
in damage to the surface or to the pad when it is
removed.
Maintenance Service
Regularly make sure the vacuum cup's air filter is
in place. If not, discontinue use until the filter is
replaced.
Since aging and water reduce the capacity of the
rubber pad, it should be replaced at least once every
2 years or whenever damage is discovered.
If the cup does not function normally, the cup face
may be dirty or damaged, or the pump may require
service. First clean the cup face as directed.
Cleaning
1. Remove the air filter from the cup face.
2. Use a clean sponge or lint-free cloth to apply
soapy water or another mild cleanser to cup
face.
To prevent liquid from contaminating the pump,
hold the cup face-down or cover the suction hole
in the filter recess while using any liquid.
3. Wipe all residue from the cup face.
4. Allow the cup to dry and reinstall the air filter.
NOTE: You can order replacement filters from

means.
