2 Proper use of the OKTOPUS®
2.1 Functional principle and safety concept of the OKTOPUS® system
Devices of the OKTOPUS® system are “load lifting attachments” operating according to
the principle “vacuum lifter”. They are mounted to a hoist or operate as a stand-alone unit
and are used for handling and positioning large-sized construction elements.
The basic functional principles of the OKTOPUS
®
system are:
⇒ controlled suction and release of large-sized construction elements having sufficient in-
herent stability using one or more suction pad of the OKTOPUS
®
,
⇒ transport and positioning of the sucked elements by manipulating the OKTOPUS
®
,
⇒ vernier positioning of the elements attached to the OKTOPUS
®
by controlling the OK-
TOPUS® axes (if available).
For various fields of application we offer different designs and types of the OKTOPUS
®
.
These differ depending on the used hoist, the loads to be lifted, the required positioning
movements and the used controls.
For further information please contact us or visit our website at
www.wirth-gmbh.com.
Specific safety requirements, which have been taken into account during construction, execution, technical documentation and in drawing up the operating instructions, result from the
function of the OKTOPUS
®
being a load lifting attachment.
Therefore, strict adherence to the instructions and information for proper and safe use given
in the operating manual is a prerequisite for the manufacturer’s warranty during the stipulated
warranty period.
Combining the OKTOPUS
®
with a hoist is the responsibility of the OKTOPUS® user. The user
himself is responsible for proper implementation of the relevant guidelines and instructions.
The instructions given in this operating manual by the OKTOPUS® manufacturer are considered to be additional support.
Prior to initial startup of the machine the suitability of the combination OKTOPUS
®
/forklift or
crane in operating conditions has to be checked by skilled personnel.
Furthermore, the OKTOPUS
®
has to undergo regular inspections by an expert (see point
4.1). An expert is a person that due to his technical training and experience has sufficient
knowledge in the area of load lifting attachments and is familiar with relevant occupational
and safety instructions, regulations and generally recognized codes of practice which enables him to assess operational safety of load lifting attachments.
The initial inspection of the combination hoist/OKTOPUS
®
as well as the successful perfor-
mance of the annual inspection of the OKTOPUS
®
by an expert has to be documented.
The OKTOPUS® manufacturer offers expert inspections as a service and documents the inspections on the OKTOPUS® by placing the inspection tag on the inspection card according
to Annex 4 with the indication of the next test date.

OKTOPUS® GLASS-Jack GL-N 400/300 by at least 50 kg in all possible working posi-
tions.
(2) Never operate a damaged, not fully functional or incomplete OKTOPUS
®
!
(3) Prior to initial startup have an expert check and document the combination crane/
OKTOPUS®!
(4) Only operate the crane with an operating license!
(5) Only operate OKTOPUS
®
and crane if you are familiar with the control and display
elements as well as the operating manuals. You have to know how the functions affect the entire construction!
(6) Prior to using OKTOPUS
®
and crane check the function of the control and display
elements as well as the warning devices!
(7) Ensure that the crane operator is able to overview the assembly and installation site!
(8) Agree on hand signals with the technician or installer for the necessary crane move-
ments!
(9) It is absolutely necessary to observe the maximum Working Load Limit of the OK-
TOPUS
®
GLASS-Jack GL-N 400/300 stipulated in section 2.3 Symbols and mark-
ings! These specifications only apply to a working height corresponding 400 m above
sea level!
(10) If the suction pads are covered by protecting cowls, these have to be removed be-
fore startup!
(11) Only work at wind speeds less than 30 km/h, otherwise you risk uncontrollable swing-
ing of the load!
(12) Check the suction rubbers daily for damages; if necessary replace the suction rub-
bers by new ones.
(13) Clean the suction areas of the glass panes. Do not place the suction pads on pro-
tective foil, releasing agents or similar, but remove it at least at the contact areas of
the suction pads.
(14) Never stand or walk under the suspended load!
(15) Make sure that nobody climbs the OKTOPUS
®
GLASS-Jack GL-N 400/300 or the
suspended load and tries to ride along.
(16) Stop working instantly if the acoustic alarm sounds and/or the red warning light
is illuminated! In this case the system is severely damaged and there is the risk that
the sucked load might drop. Carefully lower the OKTOPUS® together with the sucked
load with the help of the used hoist until the load is securely placed. The cause of the
alarm has to be found and removed. In case of unrecoverable errors all operations with
the OKTOPUS
®
have to be discontinued immediately. The OKTOPUS® has to be se-
cured against further use.
(17) In case of incidents and maintenance work turn off the OKTOPUS
®
.
(18) After use, protect the suction pads of the OKTOPUS
®
against damage by using protec-
tion cowls!
(19) Take into consideration that low temperatures and high humidity may cause freez-
ing of the vacuum system!
(20) Do not suck wet elements, because
a. Working Load Limit is decreased considerably and
b. the vacuum system or the control system of the OKTOPUS
®
could be damaged!

2.4 Structure and use of the OKTOPUS®
The OKTOPUS® GLASS-Jack GL-N 400/300 is a vacuum-based load lifting attachment for
large-sized glass and façade elements with sufficient inherent stability and a (at least) partially smooth and airtight surface.
It is designed for installation of construction elements for cladding and roofing on construction sites.
The functional main assemblies are (see fig. 1):
− the crane eye (1) to couple the OKTOPUS
®
to the crane,
− the alarm buzzer (17) and the red warning light (16), that indicates a hazardous situation,
− the vacuum gauges (5), that indicate the existing negative pressure and define the work-
ing range,
− the suction frame (9) with the attached suction pads (8),
− the charge indicator (12), that always indicates the battery’s current charge level,
− the switch “Suction/Release“ (15) to turn the OKTOPUS
®
on/off and to ensure the suc-
tion/release function.

2.5 Operating conditions and restrictions
The suction areas of the glass and façade elements to be assembled with the OKTOPUS®
GLASS-Jack GL-N 400/300:
•
have to be air-impermeable,
• have to have an even, dry, oil-free and clean surface and
• must not be covered with a protective film!
The OKTOPUS
®
is delivered with suction pads for even glass and façade elements.
Generally, no statements can be made regarding the length and the width of the elements to
be installed with the OKTOPUS
®
, as this depends – upon observing the safe work load criteria – almost exclusively on the inherent rigidity and the correlating deformation behavior of
the construction elements.
Avoid suction of oil, water, vapors or aggressive gases. Ambient temperature has to be at
least 0°C and must not exceed 40°C (applies to 1013 mbar and sea level). At low temperatures the capacity of the used batteries is reduced. The airborne sound emitted by the OK-

TOPUS® GLASS-Jack GL-N 400/300 amounts to < 70 dB (A), vibrations are < 2,5 m/s2,
which means that special protective measures are not required.
Operating restrictions result from the limited Working Load Limit of the OKTOPUS
®
GLASSJack GL-N 400/300 (see section 2.3 Symbols and markings) as well as the performance data, the operating conditions of the used crane and the conditions of the construction site. Furthermore, you have to regard the fact that the manipulated elements have to have sufficient
inherent stability and are suitable to be installed with a vacuum lifting device (if necessary
consult with the manufacturer of the elements).
Due to the broad variety of elements with many different surface coatings offered on the
market we cannot assume liability in case of possible material incompatibilities between suction rubber and surface coating.
The maximum Working Load Limit stipulated on the OKTOPUS
®
only applies to the use of
the original suction pads and a working height of maximum 400 m above sea level. Employing the OKTOPUS
®
in heights above 400 m leads to a decreased Working Load Limit of the
OKTOPUS
®
on the one hand, on the other hand the OKTOPUS® control system needs to be
adjusted. If you want to employ the OKTOPUS® in heights above 400 m, please contact the
Wirth Service Team beforehand.
When operating the OKTOPUS
®
at heights above 400 m the Working Load
Limit is reduced! The Working Load Limits stipulated on the OKTOPUS®
and in this operating manual do not apply in this case!
Never perform any unauthorized adjustments at the control system of the
OKTOPUS
®
; this may lead to severe malfunction of the device! Danger to
limb and life! Consult with the OKTOPUS® manufacturer if it is necessary to
adjust the control system of the OKTOPUS®, e.g. to perform a height adjustment.
2.6 Transport and storage
The OKTOPUS® may only be moved with a suitable hoist/means of transport with appropriate Working Load Limit.
For transport purposes take the OKTOPUS
®
out of operation by sliding the
switch “Suction/Release” to position “Release”!
Protect the rubber lip of the suction pads with protective cowls from dirt
and damage!
In order to avoid damage due to deep discharge the batteries during stor-
age, the OKTOPUS® has to be charged at least every two weeks.

3 Instructions for using the OKTOPUS®
3.1 Electrical power supply
Power supply is effected by a 24 V / 4,5 Ah battery system (2 pcs 12 V batteries).
The battery’s charge level is monitored through a charge indicator according to figure 4.
Light-emitting diodes (LED) in the signal colors green, yellow and red indicate the current
charge level after the OKTOPUS
®
has been turned on.
The following charge levels can be read from the charge indicator:
⇒ If at least one green LED is illuminated the battery is charged. You can operate the
OKTOPUS
®
.
⇒ If the third LED from the left is illuminated (yellow LED), you should charge the battery.
⇒ If the second LED from the left (yellow LED) is flashing, or the second LED from the left
(yellow LED) and the red LED are flashing alternately, the battery needs to be charged
instantly in order to avoid deep discharge and by that possible damage.
The charge indicator is arranged on the device according to figure 1.
Fig. 4: Charge indicator
Do not use the OKTOPUS
®
, if the yellow LED is flashing, or the yellow and
the red LED are flashing alternately. Possibly sucked loads shall be lowered. The OKTOPUS
®
has to be charged instantly in order to avoid deep
discharge and by that possible damage to the battery.
The user has to ensure that the battery is properly charged when operating
the OKTOPUS®.
The charge indicator only indicates the current voltage level of the battery.
It does not give any reliable information regarding the battery’s capacity.
The charge indicator responds rather slowly. In order to assess the voltage
level realistically after the charging process (see point 4.4) you have to run
the vacuum pump of the device for approximately 2 minutes, and then use
the indicated charge level of the battery as a basis for assessing how to
employ the device.
If this green
LED is illuminated
the battery is fully charged.

3.2 Vacuum supply
Vacuum supply is effected by an electrical operated vacuum pump that is powered by the
battery. Starting at the vacuum pump the OKTOPUS® GLASS-Jack GL-N 400/300 is designed as a dual circuit system. That means that all the following vacuum components such
as non-return valve, vacuum reservoir, pressure controller, vacuum gauge and suction pad
exist twice (two vacuum circuits).
The two vacuum circuits of the OKTOPUS
®
GLASS-Jack GL-N 400/300 are marked by different colors, one color per vacuum circuit (blue and red). You have to ensure that suction
pads with vacuum hoses of the same color are always arranged diagonally to each other at
the suction frame.
The OKTOPUS
®
GLASS-Jack GL-N 400/300 mounted to the crane is ready for use, when a
sufficient vacuum level is reached in both vacuum tanks. The current vacuum level is constantly indicated on the vacuum gauges (figure 5).
The green scale range is the
permissible working range from -0,65 bar to -0,9 bar.
Fig. 5: Vacuum gauge
During operation the vacuum is monitored by two pressure controllers. If the vacuum is in the
working range in both vacuum circuits, the OKTOPUS
®
is ready for use.
If the vacuum decreases impermissibly in one or both vacuum circuits or the pressure rises
above -0,65 bar (red scale range) a warning is triggered automatically:
⇒ the alarm buzzer sounds.
⇒ red warning light illuminates.
Always arrange suction pads with vacuum hoses of the same color diago-
nally to each other at the suction frame! Non-compliance with these instructions could, in case of a breakdown of a vacuum circuit, lead to the
load suddenly dropping due to uneven load distribution.
If the alarm is activated, stop working instantly and evacuate the hazard
zone, as the sucked element could disengage suddenly. Never stand or
walk under the OKTOPUS
®
or the suctioned element!
The alarm remains active until the vacuum pressure is restored within its
permitted limits.
Red range
The OKTOPUS®
must not be operated in
this range.
Green range
The OKTOPUS®
may only be operated in
this range.

3.3 Operating switch
The OKTOPUS® GLASS-Jack GL-N 400/300 is operated on the device according to fig. 6.
Fig. 6: Operating switch
3.4 Startup
In order to startup the OKTOPUS® proceed as follows:
• Place the suction pads of the OKTOPUS
®
on the element to be suctioned!
• Slightly lift the switch “Suction/Release” and slide it towards “Suction”!
• Check the battery’s charge level on the charge indicator:
⇒ operational readiness is indicated by an illuminated green LED,
⇒ If the second LED from the left (yellow LED) is flashing, or the second LED from the
left (yellow LED) and the red LED are flashing alternately, the battery needs to be
charged!
• Check the vacuum level on the vacuum gauges:
⇒ if the pressure indicated on the vacuum gauges is in the green range the device is
ready for use!
⇒ if the pressure is in the red range in one or more vacuum gauges the alarm buzzer
sounds, the red warning light illuminates and vacuum has to be built up.
• Slightly lift the switch “Suction/Release“ and slide it towards “Release“.
3.5 Handling of glass and façade elements
Prior to attaching construction elements the OKTOPUS®:
⇒ has to be coupled to the crane as a load lifting device. The coupling crane/OKTOPUS
®
has to be performed with the crane at standstill and the OKTOPUS
®
taken out of opera-
tion.
⇒ has to be configured depending on the load to be manipulated (if necessary, mount ex-
tension arms).
⇒ has to be started up according to section 3.4.

3.5.1 Handling of lying glass and façade elements
⇒ Disengage unlocking “Tilt“ (see fig. 7) and move the crane with the attached OKTOPUS
®
GLASS-Jack GL-N 400/300 to the elements. Position the suction pads parallel to the
suction area of the load by the tilting the suction frame, by driving and lifting movements
of the crane as well as manual guidance.
In order to avoid unintended rotating of the load, you have to ensure that
the release lever “Rotate” (see fig. 8) is engaged. The release lever “Tilt”
has to be disengaged and the crane arm in a vertical position!
Never attempt to lift a horizontally lying load,
if the tilting function of the crane arm is locked!
⇒ Position the suction pads of the OKTOPUS
®
above the center of mass of the load (±5
cm) and place it on the suction area. If the surface of the construction element is coated
with protective film, it has to be removed at least in the area of the suction pads before
placing the OKTOPUS
®
.
Make sure that the load is properly attached to the OKTOPUS
®
! Loads that
are not balanced can suddenly turn over or rotate!
⇒ Now the construction element is suctioned. Slightly lift the switch “Suction/Release” (see
fig. 6) and then slide it towards “Suction“ until it latches (see also section 3.4 “Startup”).
⇒ You can lift the load only if the red warning light and the alarm buzzer have turned off,
the vacuum gauges indicate that the working range has been reached (see figure 5) and
you have ensured that nobody is in the danger area.
⇒ Do not lift the load higher than necessary!
⇒ Fix the element at the installation site in that way, that it does not pose a threat after be-
ing released from the OKTOPUS
®
!
⇒ Then the construction element is released by slightly lifting the switch “Suction/Release”
and sliding it towards “Release”. Lifting the switch is an additional safety measure
against unintentional operating errors.
If your OKTOPUS
®
is equipped with the optional blow-off function, subsequently press
the button “Blow-off“ (see fig. 1, pos. 15). Keep the button pressed until all suction pads
have completely disengaged from the load. In this case the suction pads are supplied
with compressed air which ensures that the suction pads are released quicker from the
load.
As a result of the own weight of the OKTOPUS® there is still vacuum re-
maining after venting the suction pads through the vacuum system. Lifting
the OKTOPUS
®
jerkily increases this effect. For this reason, always remove
the device slowly and evenly from the installed elements!

In order to avoid unintended rotating or tilting of the load, you have to en-
sure that the release levers are engaged (see fig. 8)!
⇒ Position the suction pads of the OKTOPUS
®
above center of mass of the load (±5 cm)
and place it on the suction area. If the surface of the construction element is coated with
protective film, it has to be removed at least in the area of the suction pads before placing the OKTOPUS

fig. 6) and slide it towards “Suction“ until it latches (see also section 3.4 “Startup“).
⇒ You can lift the load only if the red warning light and the alarm buzzer have turned off,
the vacuum gauges indicate that the working range has been reached (see figure 5) and
you have ensured that nobody is in the danger area.
⇒ Do not lift the load higher than necessary!
⇒ Fix the element at the installation site in that way, that it does not pose a threat after be-
ing released from the OKTOPUS
®
!
⇒ Then the construction element is released by slightly lifting the switch “Suction/Release“
and sliding it towards “Release“. Lifting the switch is an additional measure against unintentional operating errors.
If your OKTOPUS
®
is equipped with the optional blow-off function, subsequently press
the button “Blow-off” (see fig. 1, pos. 15). Keep the button pressed until all suction pads
have completely disengaged from the load. In this case the suction pads are supplied
with compressed air which ensures that the suction pads are released quicker from the
load.
As a result of the own weight of the OKTOPUS® there is still vacuum re-
maining after venting the suction pads through the vacuum system. Lifting
the OKTOPUS
®
jerkily increases this effect. For this reason, always remove
the device slowly and evenly from the installed elements!

3.5.4 Tilting a vertically hanging load
⇒ Suction the element as described in 3.5.2!
Never release the unlocking “Tilt” (see fig. 8) when loaded! This would re-
sult in the load tipping down uncontrollably!
In order to tilt the load from a vertical into a horizontal position at least 3
persons are required. Two persons secure and guide the load; the third
person operates the unlocking!
⇒ Before tilting the load, please note that a tilted load requires more horizontal room. Make
sure that the load cannot hit anything when being tilted!

4 Service and Maintenance
4.1 General remarks
Since the OKTOPUS® system is a load lifting attachment both the manufacturer and the operator carry a high responsibility to guarantee the relevant safety standard throughout the entire operating time. Thus, service and maintenance are of great importance.
For maintaining a high level of operational safety the OKTOPUS
®
GLASS-Jack GL-N
400/300 has to be inspected by the service workshop of Wirth GmbH or by an especially
qualified person
⇒ at least every 12 months or in shorter intervals, if required by national standards or
regulations or
⇒ after special incidents.
Additional operative and scheduled maintenance and service work may only be performed by
a skilled expert. Maintenance and service work may only be performed when the device is
taken out of operation.
Before performing any repair and maintenance work switch off the OK-
TOPUS
®
; slightly lift the switch “Suction/Release” and slide it towards “Re-
lease”.
Defective parts may only be replaced with original spare parts. They will be provided on request after consulting with the service team of the OKTOPUS
®
manufacturer. Using not orig-
inal spare parts leads to exemption from liability by the manufacturer.
In order to perform maintenance and service work an appropriate tool kit has to be used.
Maintenance has always to be followed by a functional check.
If damages cannot be repaired by the operator’s staff the Wirth GmbH service workshop
needs to be informed.
4.2 Mechanical system
The mechanical system is sturdy and provided with a surface protection. Maintenance works
on your side comprise
⇒ daily visual inspection of the mechanical components of the OKTOPUS
®
GLASS-
Jack GL-N 400/300 for damages before startup.
The OKTOPUS
®
GLASS-Jack GL-N 400/300 is a load lifting attachment. Therefore, repairs
on the mechanical function parts shall exclusively be carried out by the OKTOPUS® manufacturer.
Do not perform any repairs at mechanical functioning parts!

4.3 Vacuum system
Vacuum components, subjected to wear and being relevant to safety have to undergo inspections on a regular basis. You have to
⇒ daily check the components in terms of their correct position and mechanical damag-
es, especially
• the suction pads (if necessary, replace suction pads),
• the hoses,
• the vacuum gauges.
Replace the suction pads and the hoses immediately if these have mechan-
ical damages (cracks, cuts, etc.)! These damages could lead to a reduced
Working Load Limit of the OKTOPUS
®
.
The vacuum pump works oil free. The solid design allows maintenance-free operation.
The infiltration of dust into the vacuum pump is prevented by dust filters. For this reason
maintenance of the vacuum system focuses on this component and mainly consists of
:
⇒ replacing the dust filter if it is polluted. The dust filters are located under the bonnets of
the OKTOPUS
®
(see fig. 1, pos. 2 and 6).
Fig. 12: Dust filter
4.3.1 Cleaning the suction pads
Always clean the suction pads prior to every operation of the OKTOPUS
®
, if the suction areas are soiled (dirt, dust, oil, etc.). Dirt could cause leakages and leave marks on the manipulated elements.
For cleaning the suction pads we recommend to use water, if necessary add some detergent. Do not use chemical solvents, petrol, diesel oil or similar in any case.
Never use solvents, petrol or aggressive chemicals for cleaning the suction
pads! Otherwise this may result in damaging the suction pads, which could
endanger the operator as well as others.
Ensure that fluids cannot enter the vacuum system during the cleaning process by positioning the suction pads or by covering the suction opening. Give the suction pads a sufficient
amount of time to completely dry before operating the OKTOPUS
®
.

5 Handling incidents
Incidents are indicated by the red warning light and the sound of the alarm buzzer. A fading
sound of the alarm buzzer signals total breakdown of electrical power supply.
Fig. 14: Warning equipment
When the alarm buzzer sounds and/or the red warning light flashes immediately leave the
danger area, since the sucked element might suddenly drop. Locate and eradicate the cause
for the alarm. If you cannot remedy the fault, stop operating the OKTOPUS
®
immediately. Af-
ter releasing a possibly sucked element the OKTOPUS
®
has to be secured against further
use.
In case of faults that cannot be remedied, working with the OKTOPUS
®
shall be stopped immediately. The OKTOPUS® has to be secured against
further use.
