ASSEMBLY AND MOUNTING
Read these instructions before
starting any assembly or moun-
!
ting work.
Improper mounting work can
cause hazards during use of the
CAUTION!
crane.
Mounting carried out in a manner other than that
specified in this manual can expose the user to
danger and will void the manufacturer's guarantee.
Check the stability of the crane-vehicle assembly by
performing the necessary calculations. See Section
"Determining the stability".
The mounting must be performed by the manufac-
turer or a service center or person authorized by the
manufacturer.
The strength class of the mounting bolts is 8.8. Use
self-locking nuts, e.g., DIN985.
Tightening torque 420 Nm!
Retighten the bolts after the test
run and the first day of use.
!
CAUTION!
INSTALLATION INSPECTION
Decisions 354/83 and 530/83 made by the Finnish
Council of State stipulate that an installation inspection
must be performed for each crane-vehicle assembly
before use. An inspection form can be found in this
manual.
The person performing the inspection must be familiar
with the crane's construction and operation.

MOUNTING THE MULTI- AND DOUBLE-ACTING
VALVES
!
CAUTION!
Install the valve using the included bracket at the de-
sired location, paying attention to the direction of the
hoses and movement during loading and transferring
so that there is no risk of abrasion or clamping.
The label indicating the safe distance from live conduc-
tors must be clearly visible during operation.
!
DANGER!
The levers in the multi-lever valve can be moved to dif-
ferent positions if necessary. Detach the levers from the
valve before moving them.
CONNECTION TO THE HYDRAULIC SYSTEM
Before connecting the crane to the tractor's hydraulic
system, make sure that the oils are compatible.
The crane has been tested using 10W/30 oil that meets
the API SE, CD, and API GL-4 requirements.
We recommend connecting the pressure hose to
the single-acting hydraulic outlet and the return hose
to the tank via the return filter. The filter's intended flow
rate is 80 l/min and the filtering density 25 μm abs.
The crane can also be connected to the double-
acting hydraulics outlet. If this is done, make sure
that the lever of the double-acting valve controlling
the flow is in the right position so that the pressure
is directed to the pressure connection of the crane's
control valve. Check the operation of the double-
acting outlet in the vehicle's operating manual.

The valve must be positioned or
covered so that the levers cannot
be used inadvertently.
Hoses in the operator's cabin
must be protected so that the
user is not endangered by oil jets
in the event of breakage.
