ATTENTION
The outrigger beams are in their working position when the yellow band existing on every beam
can be entirely seen.
• Lower to the ground the bearing pads of the outriggers jacks, one at a time, acting as follows:
Hydraulic jack (Fig. 16)
Open the shut-off valve (
1
) to allow the lowering to ground of the cylinder’s pad and rod (
2
). The valve is
open when its lever is on position “
A
”. Operate the corresponding lever of the control valve until the pad
reaches the ground. Avoid to lift the truck off the ground unloading the vehicle suspension, this reduces
greatly the stability of the truck. Then, turn again the valve lever to its previous “
C
”closed position.
Mechanical jack (Fig. 17)
Lower the pad (
4
) by pulling the locking pin (
5
) out of its housing. The telescope and the pad will come down
because of gravity. When it is close to ground, engage again the pin in the appropriate hole, securing it with
the relevant safety retainer (
6
). Turn the crank handle (
7
) until the ground is reached, bearing in mind what
was explained above regarding the vehicle suspension.
Swinging hydraulic jack (Fig. 18)
When swinging jack are fitted, before operating the shut-off valve (
1
) make sure that the jack (
2
) is in vertical
position, with its pad (
3
) oriented downward, its pin (
4
) secured with the retainer spring (
5
). If not, take off the
pin, turn the jack downward and then lock in the working position in the aforesaid way. Then open the valve
(
1
) as already explained (hidraulic jack), operate the corresponding lever of the control valve and lower the
pad to the ground as described before. When duly positioned, close the valve (
1
) as described.
ATTENTION
When turning the swinging jack and removing its pin, be careful and hold it up, to prevent it from
falling down because of gravity , resulting in damage or injuries.
• Repeat this sequence of operations for the outrigger jack on the other side of the truck and for every
other jack fitted on the truck. Make sure that the vehicle is level, in order to have a good stability.
Maximum allowed angle is 3°.
IMPORTANT
Proper leveling has to be checked by means of a level instrument fitted on the truck.
