wear and tear or damage. Do not attempt
to lift anything with the tool until you
have replaced the seal.
f) Use caution when lifting large thin
flexible sheets, like drywall, cardboard,
plastic, plywood, thin sheet metal
etc.
Thin sheets bend and flex and can
unexpectedly change curvature above
their limit and detach.
g) Do not attach the tool to surfaces
with visible puddles of water. Internal
components are not waterproof. If water
is sucked into the air ducts it can cause
permanent damage to the tool. The
GRABO® Pro-Lifter 20 is not waterproof
and therefore extreme caution should
be taken when using in the rain or wet
conditions.
h) Do not drop the tool from heights above
1.5 meter above the ground (chest level).
If dropped by accident, inspect the seal
side lips for damage.
i) Do not place heavy objects on top of the
tool.
j) Do not place the digital display in direct
sunlight or near strong heat sources for
prolonged periods.
Extreme heat may
damage the display and it may become
unreadable. A damaged display does not
necessarily impact the functionality of the
tool.
k) To avoid overheating, do not cover the
tool.
l) Ensure the switch is in the off-position
before transporting the tool and when
in storage.
Be mindful that the tool is not
switched on accidently.
! WARNING! Weight may drop without
warning if the safety precautions are not
met! The GRABO® Pro-Lifter 20 creates a
strong vacuum. In case the seal is broken
or the allowed weight is exceeded or
any other factor that causes the negative
pressure to release spontaneously, this
kind of failure will happen suddenly and
absolutely without any sensory indication
or warning. You will not notice 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.
RUBBER FOAM SEAL USAGE AND SAFETY
! The rubber foam seal is made of two
parts: black rubber foam and red silicon
seal. Black rubber foam is mostly used to
create initial vacuum. After it compresses,
the red seal holds the longest and
strongest seal. As long as the initial seal is
created to get suction, the “strong” seal
will also be created. 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 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
