RUBBER FOAM SEAL USAGE AND SAFETY
SE
! The rubber foam seal is made of two
DK
parts: black rubber foam and red silicon
AR
seal. Black rubber foam is mostly used to
RU create initial vacuum. After it compresses,
the red seal holds the longest and
TR
strongest seal. As long as the initial seal
is formed to get suction, the "strong" seal
will also be formed. The rubber foam
seal 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 with 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.

the weight detaching and there will be no
possibility to stop or catch it. This is very
dangerous, especially with heavy loads.
Therefore all safety precautions should be
kept to the maximum.
d) Always store the seal covered with a hard
cover. The seal can be easily damaged by
sharp corners and edges in storage. The
seal should not be stored with any sharp
tools or in contact with any hard objects
(e.g. inside a toolbox).
e) Do not dip the seal in water. The rubber
foam seal is slightly water absorbent.
Unless it is fully dipped in water and
soaking wet, slightly soaking the seal with
water will not damage its performance. If
it is soaked in water, it can be squeezed
by hand like a sponge to dry without
damage. It is advisable to use a dry seal to
avoid water getting sucked into air ducts
and inside the body.
! Do not dip or use the seal in the
presence of oil-based products. Oil and
oil products (machine oil + lubricants) will
permanently damage the seal and cannot
be removed. If the seal has absorbed
any oil, it should be disposed of safely,
the base should be cleaned, and the seal
replaced.
! Do not use or store the seal in the
presence of chemical solvents. Kerosene,
acetone, turpentine, benzene, acids, etc.
and even their fumes in closed spaces
or thin layers on surfaces can melt the
seal and damage its structure and cause
failure.
