- Hydraulic hoses with 2 steel plaitings according to
DINEN8532SN,
- Hydraulic pipes, seamless cold-drawn steel pipes
according to DINEN10305.
2.9 Media/consumables,
precautions
WARNING Hot hydraulic oil under high pressure
Hydraulic oil will squirt out under high pressure if there is
a leakage. The jet of oil might penetrate people's skin
and cause permanent damage. Hot hydraulic oil can
cause burns.
uNever use your hands to find leaks.
uAlways keep your face away from a possible leak.
uIf hydraulic oil has penetrated your skin consult a
doctor immediately.
WARNING Hydraulic oil spills
Spilt hydraulic oil can make a floor slippery. If people slip
they can be injured. Hydraulic oil is environmentally
harmful and must not penetrate the ground or enter the
water table or water supplies.
uMake sure not to spill any hydraulic oil.
uImmediately clean the floor if you have spilt hydraulic
oil.
uObserve all safety and environmental protection pro-
visions when handling hydraulic oil.

precautions
DANGER Explosion and fire
Explosions cause serious injury or death. Explosives be-
ing cut by the hydraulic attachment may lead to an ex-
plosion.
uNever operate the hydraulic attachment in the direct
vicinity of explosives.
uMake sure that no explosives are hidden in the con-
crete.
uCheck gas line position plans of the complete con-
struction area.
DANGER Explosion and fire
Operating the hydraulic attachment may create sparks
which ignite highly flammable gases.
This may lead to fire or an explosion.
uNever work in an environment with highly flammable
substances.
uMake sure that there are no hidden sources of gas in
the work area.
uCheck gas line position plans of the complete con-
struction area.
DANGER Explosion and fire
Dust-rich air can form an explosive atmosphere which
may ignite when operating the hydraulic attachment.
This may lead to fire or an explosion.
uNever operate the hydraulic attachment in an explo-
sion-hazard atmosphere.
uAlways provide sufficient ventilation when working in
buildings or in a confined area.
2.11 Electrical shock, precautions
DANGER Electrical shock
Any contact of the hydraulic attachment with electric cir-
cuits or other sources of electricity will lead to an electric
shock, resulting in serious injury or death. The hydraulic
attachment is not electrically insulated.
uNever work in the vicinity of electric circuits or other

work area.
uCheck wiring diagrams.
2.12 Falling stones, precautions
WARNING Fragments flying around
Fragments of material which come loose while operating
the hydraulic attachment may be flung away and can
cause serious injury if people are hit by them. Small ob-
jects falling from a great height can also cause serious
damage.
During hydraulic attachment operation the danger zone
is considerably greater than during the excavation oper-
ation due to fragments of stone and pieces of steel flying
around, and for this reason the danger zone must, de-
pending on the type of material to be worked on, be en-
larged correspondingly, or secured in a suitable manner
through corresponding measures.
uSecure the danger zone.
uStop the hydraulic attachment immediately if anyone
enters the danger zone.
uClose the windscreen and the side windows of the
driver's cab.

Dust may be generated when operating the hydraulic at-
tachment. If dust from rocks or silica dust, produced
when operating the hydraulic attachment on rocks, con-
crete, asphalt or other such materials, is inhaled this
may lead to silicosis (dust lungs, a severe lung disease).
Silicosis is a chronic disease which may lead cancer and
death.
uWear a suitable breathing mask.
2.14 Handling machines,
precautions
WARNING Narcotics, alcohol and drugs
Narcotics, alcohol and medicinal drugs make their users
less alert and affect their ability to concentrate. Negli-
gence and incorrectly assessing a situation can result in
serious injury or death.

uModifications that entail new hazards may require a
new procedure for assessing conformity.
2.16 Environmental pollution,
precautions
NOTICE Environmental pollution due to hydraulic oil
Hydraulic oil is permanently environmentally harmful. Es-
caped hydraulic oil will lead to groundwater and soil con-
tamination. Organisms may die.
uCollect any hydraulic oil which escapes to avoid envi-
ronmental pollution. For minor volumes use an ab-
sorbing medium (in case of an emergency use soil).
In case of major leakages contain the hydraulic oil. It
must not drain off and penetrate the ground or enter
the water table or water supplies.
uCollect contaminated absorbing medium or soil in a
watertight box/container and close it tight.
uContact an authorized waste management company.
uDispose of all contaminated material in accordance
with the applicable environmental regulations.

3.2 Function
The operation of a multi grapple is described in a simpli-
fied version below:
Closing the multi grapple
The carrier driver operates the multi grapple, via a switch
on the floor or via a joystick in the carrier, for the function
»Close«. Line »B« is connected to the hydraulic cylin-
der. The hydraulic cylinder extend the piston rod. The
grapple leaves grip the material.
Opening the multi grapple
The carrier driver operates the multi grapple, via a switch
on the floor or via a joystick in the carrier, for the function
»Open«. Oil is fed to the hydraulic cylinder via line »A«.
The piston rod retracts. The grapple leaves opens.
Hydraulically turning the multi grapple
The carrier driver activates the carrier function »Turn«.
Oil is fed to the hydraulic motor. The hydraulic motor, lo-
cated in the rotation mechanism housing of the multi
grapple, causes the rotation. To achieve endless turning
of the housing, there is a rotary transmission. The oil
flows for the functions »Open« and »Close« are trans-
mitted through the rotary transmission.
3.3 Signs / labels
WARNING Missing warnings
The name plate and the labels on the hydraulic attach-
ment contain important information about the hydraulic
attachment and for personal safety. A missing warning
can lead to overlooking or misinterpretation of possible
risks and cause personal hazards. The signs and labels
must always be clearly legible.

WARNING Hoist tipping over / hydraulic attach-
ment falling
The hydraulic attachment is heavy. The hoist/lifting
equipment and/or hydraulic attachment tipping over or
falling may cause serious injury and material damage.
uOnly transport the hydraulic attachment with lifting
equipment with the right load-bearing capacity for the
weight of the hydraulic attachment.
uOnly lift and secure the hydraulic attachment with lift-
ing gear (ropes, chains, shackles etc.) with the right
load-bearing capacity for the weight to be lifted.
uMake sure that there is nobody near or under the
suspended hydraulic attachment.
nTransport the multi grapple with the grapple leaves
open.
There is less oil in the multi grapple if transported
with open grapple leaves. In the event of a leak, less
oil is lost and the environmental damage is less.
nOpen the multi grapple before transporting it. Pro-
ceed as follows to ensure the grapple leaves stay
open:
nSeal all hose ports and connections on the multi
grapple with the enclosed plug fittings and cap nuts if
the hydraulic hoses are removed.
nIf the hydraulic hoses have been attached to the multi
grapple, plug the hoses.

5 Installation
WARNING Hot hydraulic oil squirting out
The hydraulic system is under high pressure. If hydraulic
connections come loose or are disconnected, hydraulic
oil will squirt out under high pressure. Hydraulic oil
squirting out can lead to serious injury.
uDepressurise the hydraulic system before connecting
or disconnecting the hydraulic circuits of the hy-
draulic attachment (see chapter Depressurising the
hydraulic system).
NOTICE Environmental damage due to hydraulic oil
Hydraulic oil is environmentally harmful and must not
penetrate the ground or enter the water table or water
supplies.
uCollect any hydraulic oil which escapes.
uDispose of it in accordance with the applicable envi-
ronmental regulations.
NOTICE Damage to the hydraulic attachment
Working with a hydraulic attachment mounted to a long
reach boom may cause damage to the hydraulic attach-
ment.
uBefore working with a hydraulic attachment mounted
to a long reach boom consult the Epiroc Customer
Center / Dealer in your area.
5.1 Media/consumables
The following consumables are used when operating the
hydraulic attachment:
5.1.1 Mineral hydraulic oil
All hydraulic oil brands prescribed by the carrier manu-
facturer are also suitable for use when operating the hy-
draulic attachment.
However, the oil should comply with viscosity class
HLP32 or higher.
In summer and in hot climates, oils of viscosity class
HLP68 or higher should be used.
In all other respects the regulations of the carrier manu-
facturer are to be taken into consideration.
Optimum viscosity range =30 - 60cSt
Max. start viscosity =2000cSt
Max. oil temperature =80°C
Special conditions apply to using the hydraulic attach-
ment at low temperatures (see chapter Low ambient
temperature).
nCheck the oil filter!
An oil filter must be integrated in the tank line of the
hydraulic system. The maximum mesh width allowed
for the oil filter is 50microns; it must have a magnetic
separator.
5.1.2 Non-mineral hydraulic oil
NOTICE Mixed hydraulic oil
Never mix mineral and non-mineral hydraulic oils! Even
small traces of mineral oil mixed in with non-mineral oil
can result in damage to both the hydraulic attachment
and the carrier. Non-mineral oil loses its biodegradability.
uOnly use one type of hydraulic oil.
If you are using non-mineral oil it is imperative that the
name of the oil in use be indicated when returning the
hydraulic attachment for repair.
In order to protect the environment or on technical
grounds, hydraulic oils are currently being used which
are not classified as HLP mineral oils.
Before using hydraulic oils of this kind it is imperative to
ask the carrier manufacturer whether operations with
such fluids are possible.
Our hydraulic attachments are basically designed for use
with mineral oils. Consult the Epiroc Customer Center /
Dealer in your area before using other hydraulic oils ap-
proved by the carrier manufacturer. Following initial as-
sembly and after any workshop repairs, our hydraulic at-
tachments are subjected to a test run on a test bed pow-
ered by mineral oil.
5.1.3 Grease
nWhen handling oils and greases observe the safety
instructions that apply to these products.

5.2 Manufacturing the adapter
plate
Construction Tools GmbH also supplies base plates to
manufacture adapter plates alternatively to the adapter
plates supplied.
NOTICE Adapter plate cracking
The adapter plate may crack if it is not designed for the
high load.
uTake not only the weight of the hydraulic attachment
but also the crowd force of the carrier, possible vibra-
tion etc. into account when dimensioning the adapter
plate.
uEnsure that the design conforms to the state of the
art.
uHave the web plates welded to the adapter plate
base plate by a qualified welding specialist.
The base plate is made of the material EN10025-S355
J2G3.
nHave the web plates designed and manufactured or
procure web plates to fit your carrier.
nEnsure that the web plates are welded to the base
plate side marked "TOP".
The adapter plate must not strike in any position during
operation of the hydraulic attachment.
Construction Tools GmbH does not design, manufacture
or sell web plates for adapter plates.
5.3 Installing the adapter plate
NOTICE The adapter plate can come loose
The adapter plate can come loose if the fastening
screws are not designed for local high loads.
uOnly use the Allen screws of strength category 8.8
and the pairs of lock washers included in the delivery
to attach the adapter plate or the base plate.
nPlace the hydraulic attachment within the range of
the carrier.
nApply anti-seize compound to the Allen screw
threads(A) before inserting them.
The contact faces of the screw head and the lock wash-
ers(B) must not be lubricated.
