Do not place the cup face against
surfaces that could damage the
sealing edges.
x.
Do not touch the release tab Ⓔ or
the pressure release button Ⓐ while
lifting. Do not use solvents, gasoline
or other harsh chemicals on the
suction pad.
If the OTTOVAC sealing force begins to
noticeably decrease while the battery is
fully charged, check the rubber seal for
wear and tear or damage. Do not attempt
to lift anything with the OTTOVAC until
you have replaced the seal.
!
WARNING: Weight may drop
without warning if the safety
precautions are not met! The
OTTOVAC 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.
