USE AND CONTROLS
The controls and signalling devices available on the platform are illustrated in this section. A perfect
knowledge of these devices is essential for the operator, and it is absolutely necessary for him to be
familiar with the controls and the relevant symbols before starting to use the machine.
STABILISING OF THE VEHICLE
To work in safety, perfect stabilising of the vehicle is essential..
Make sure that the ground is firm, and that there are no underground trenches which might give way.
The few minutes spent making sure that the machine is stable will more than make up for the possibility
of having to reposition the machine just as work has started.
With the hand brake of the vehicle on, the gear lever in neutral position (no gear engaged) , accelerate
the engine until the number of turns indicated of the label in the driver's cab is reached. Press the clutch
pedal down as far as it will go and then engage the power take-off lever. A red light will turn on to signal
that it has been engaged.
While operating the outriggers check visually that no-one can be injured as the jacks are being
lowered to the ground. If it is not possible to see all the outriggers from the control station , fence off
the area to prevent access.
The controls for the outriggers are on the right side of the vehicle (see item 9) consisting of four control
levers, each of which operates a single outrigger. By pushing down the lever the corrisponding
outrigger should be lowered, by pulling up the lever the corrisponding outrigger should be raised .
When the vehicle is lifted off the ground, a green "enabled" indicator lamp -F- turns on allowing all
the boom functions.This lamp is located on the electric box near the outrigger control box.
Use the level indicator to make sure that the vehicle is on a perfect level. If it is not, use the control
levers to lower the appropriate one.
If not otherwise indicated, the max. slope allowed is 1°.
Once this operation has been completed, check that the green "Enabled" lamp is on.
To achieve correct stabilisation, the wheels of the vehicle must have been lifted off the ground.
For machines fitted with box-type oblique outriggers, it is compulsory to extend them until the green
area is reached.
Before starting to raise the cage, it is always advisable to make sure that all the outriggers are resting
on firm ground, with no holes, protruding stones, manhole covers, grantings or bridging structures,
since these are unable to guarantee solidity.
If it is necessary to work on ground which is not very firm, a hard wooden plank must be placed under
the outrigger in question.
For machines equipped with a 5th foot under the operator's cab, check that once stabilising has been
completed, this foot is not loaded with a weight and only just touches the ground. If it is too far from
the ground, after completing stabilising reduce the gap by inserting a hard wooden plank underneath
this foot.
IMPORTANT NOTICE: ONCE THE WHEELS HAVE BEEN LIFTED OFF THE GROUND, THE HAND-
BRAKE OF THE VEHICLE NO LONGER HAS ANY EFFECT. IF THE VEHICLE IS ON A SLOPE,
THEREFORE, IT MUST BE BLOCKED IN PLACE BY MEANS OF WEDGES OR OTHER EQUIVALENT
SYSTEMS.
At this point it is possible to start lifting the cage.
