3.3.3 Operating procedures
The machine is equipped with an inclination control system disabling lifting in case of unstable positioning. Working
operations can be
resumed only after placing the machine in a steady position. Should the audible device and the red
light on the platform control panel turn on, the machine is not correctly positioned (see paragraphs relevant to “General
use instructions” ). Bring it to sa
fety rest position before starting operations again. If the tilt alarm is activated with
platform lifted, the only possible platform operation is lowering.
The machine is equipped with a platform overload controller disabling the platform lifting and lower
overloading. In case of platform overloading when lifted, also drive is disabled. Platform operation can be resumed only
after removing the exceeding load. Should the audible alarm and the red light located on the platform control panel turn
on, then the platform is overloaded (see chapter "Red warning light overload"). Remove the exceeding load before
starting operations again.
The machine is equipped with a device to avoid the risk of shearing and crushing in the lifting structure in compli
with EN280:2001: the lowering movement is automatically stopped in a position where the vertical distance between the
scissor ends is over 50 mm. In this condition the movement alarm warns about the danger condition by increasing its
frequency. The op
erator on the platform must release the lowering control and wait until the alarm stops (about 3 sec.),
then he can resume the lowering control (see chapter "Lifting and lowering").
Electric-powered machines feature a device for checking the state of
battery charge (battery protection): when battery
charge is at 20% the operator on the platform is informed of this condition through a flashing red light. In this condition
lifting is disabled, battery should be immediately charged.
Do not lean over the platform rails.
During operations in public areas surround the working area by means of barriers or other suitable signs.
Do not use the thermic drive power (Diesel or Petrol motor) indoors or in insufficiently ventilated areas.
Make sure that no people, a
part from the operator, are in the area where the machine is operating. While moving the
platform or operating the outriggers, the operator should pay particular attention to avoid any contact with the personnel
on the ground.
Specially provided microswit
ches located on the (optional) levelling outriggers control their position. When the cylinders
are lowered, drive is disabled. In order to carry out the drive, lift the pads completely.
To avoid any improper use, machines with (optional) levelling outrigge
rs are equipped with a suitable microswitch that
checks the position of the platform. When the platform is at a height above 3 meters from the ground the levelling
outriggers cannot be operated.
Lift the platform only if the machine is resting on solid and horizontal surfaces.
Drive the machine with lifted platform only if the ground is solid and horizontal.
A sensor controls the swinging of the oscillating axle. With platform raised if the wheels of the oscillating axle are not on
the same ideal plane as t
hose of the fixed axle (with some tolerance) drive is prevented and a red light will turn on to
warn of this condition. In order to be able to drive the machine it is necessary to lower the platform.
Always place working tools in a steady position to prevent them from falling and hurting the operators on the ground.
After each work session, always take the keys out of the control panels and keep them in a safe place to prevent
unauthorized people from using the machine.
When choosing the positioning point of the chassis, to prevent unexpected possible contacts with obstacles, always observe the
figures carefully as these make it possible to identify the range of action of the platform ( chap. 2).
