FOAM SEAL USAGE AND SAFETY
! The foam seal, made of black rubber foam uses patented
technology and is one of the main components of the tool. It
should be handled with caution as it directly impacts the
overall performance and safety.
a) The seal can withstand an estimated 900 compression
cycles, depending on force and duration of compression,
without any damage.
b) Avoid rubbing the seal over rough surfaces. Seal material is
very prone to parallel wear (moving parallel to rough surface
in ironing motion). Lift perpendicularly on very rough
surfaces. Rubbing the seal over a smooth surface such as
granite in the presence of thick abrasives (thick sand) will
damage the seal and may cause unexpected detachment.
c) Surfaces with very sharp edges should not be lifted in
parallel hold. Edges sharper than 45 degrees may damage the
seal and lead to sudden vacuum loss and sudden detachment.
The motor should always be on.
d) Always store the seal covered with a hard cover. The seal
can be easily damaged by sharp corners and edges when in
storage. The seal should not be stored with sharp tools or in
contact with any hard objects (e.g. inside a toolbox).
e) Do not dip the seal in water. The foam seal is slightly water
absorbent. Unless it is fully dipped in water and soaking wet,
