RETRACTING THE BOOM
Retracting the boom manually.
- CAUTION -
These procedures must be carried out by two quali-
ed and expert operators with the authorisation of the
Safety Manager.
1. Extract the movement lever and insert in its housing on
the distributor (g.85 Pos. “A” – “B” – “C”).
2. Act on the lever of the distributor of the manoeuvre to
carry out (g.85), bearing in mind that:
- LEVER A UPWARDS - raises the boom.
- LEVER A DOWNWARDS - lowers the boom.
- LEVER B UPWARDS - rotates the turret towards the right.
- LEVER B DOWNWARDS - rotates the turret towards the left.
- LEVER C UPWARDS - retracts the boom.
- LEVER C DOWNWARDS - extends the boom.
- LEVER D - Pivot and turn (DO NOT USE)
- LEVER E- Additional movements (DO NOT USE)
3. The second operator on the ground must take out the
rod from the toolbox and insert it in the emergency hand
pump housing (g.86 Pos. “1”).
4. To carry out movements, enable the emergency pump.
The second operator must push the rod to its limit stop
rst from one side and then from the other to provide the
system with pressure; this operation has to be carried
out until the movement has been completed.
5. Carry out points “1” and “3” for every single manoeuvre.
6. When the boom has been completely retracted, restore
the original conditions; close the distributor system door
and return the rod to the toolbox.
- CAUTION -
Before pumping, act on the distributor lever to carry out
the desired manoeuvre. Pumping without shifting the lever
discharges the oil from the distributor and thus more effort is
required to carry out the manoeuvres.
- CAUTION -
When the machine is in the emergency pump condition, the anti
roll-over systems are disabled. You must consult the loaddia-
gram (in the handbook in the cab and in “Use and Maintenance”)
before carrying out any manoeuvre with the distributor levers.
In this way it is possible to know the exact position the basket
is in and the work area within which it is possible to operate
thanks to the inclinometer and the letters on the boom.
When retracting the basket, do not carry out any movements
that could jeopardise machine stability; danger of rolling-over.
- CAUTION -
Only use levers “A”, “B” and “C” (fig.85) for recovery ope-
rations. The levers for pivot-turn and additional movements
“D” and “E” (g.85) must not be used because they can put
people and things at risk.
