A.1 HOW THE EXPRESS APPLIES OIL
The Express uses wicking foams to transport the oil from the oil tank onto a roller. The
roller then “holds” the oil for pick up by the buffer brush. The buffer brush then brushes the
oil onto the lane surface. Because the roller only holds the oil and the buffer brush only
applies what it picks up from the roller, the majority of the oiling pattern is determined by
the amount and placement of oil put on the roller by the wicking foams.
The wicking foams use capillary action
1
to move the oil. Capillary action virtually “sucks up”
the oil from the bottom of the foam to the top of the foam, moving the oil through the
channels created by the holes in the foam. The density - the number of holes per square
inch - determines how much oil is moved in a given amount of time and space. Less dense
foams hold less oil but the oil moves quickly because the channels created by the holes are
large and relatively straight. Denser foams hold more oil but the oil moves slowly because
the channels created by the holes are small and winding.
A.2 TESTING YOUR CURRENT DISTANCES
After you have unpacked the Express and familiarized yourself with it, run the machine on
your lanes to see how well the Express machine conditions your lanes with your current
distances. For the oiling and buffing distances, enter the oiling and buffing distances you
currently use, fill the tanks, then clean and condition each lane
twice
. After cleaning and
conditioning the leans, perform the checks listed on the next pages for each lane to
determine if you need to change any of the settings. Remember: Your goal is to find the
best pattern for all your lanes.

Capillary action is caused by adhesion, cohesion, and surface tension. Adhesion is the attraction of molecules of different
materials - in this case, foam and oil. Cohesion is the attraction of molecules of the same material - in this case, oil. Surface tension
is the “skin” that keeps the molecule from breaking apart. In the foams, the oil is attracted to a foam molecule at the bottom edge of
the foam. Because the surface tension of the oil keeps the molecule together, the molecule has no place to go but up. And as it
goes up, it finds the edge of another foam molecule to which it becomes attracted. Because of cohesion, as that first oil molecule
crawls from one foam molecule to the next, another oil molecule comes with it. And a third comes with the second, and so on. As
each addition oil molecule joins the chain, the higher and higher the first oil molecule gets supported as it crawls up until it no longer
has new foam molecules to get attracted to - in this case, the top edge of the foam.
