1.3 Description of the POLARO®L/XL
The POLARO® L/XL is a spreader for spreading winter salt, gravel and
sand. It consists of a solid frame, a spreading material tank, the electrical
components and mechanical assemblies such as a screw conveyor and
spreading device.
The electrical components comprise the drive motors for the screw
conveyor and spreading disk, the vibrator, the terminal box, sensors,
the data and battery cables and the control panel.
The screw conveyor transports the material from the tank to the
spreading device with its spreading disk. The vibrator loosens the
spreadingmaterialinthetankifnecessarytomakesurethatitcanow
through the system.
The control panel allows the speed of the screw and the spreading disk
to be adjusted from the driver's cab.
The POLARO®L/XL must be mounted on the load space of approved
carrier vehicles with an adequate axle load.

1.8 Emergency Stop switch
Warning!
Danger of death from non-functional safety equipment!
Your safety is only assured if all safety equipment is intact.
Therefore:
•Check before starting work that the safety equipment is
functional and correctly installed.
•Never disable the safety equipment.
•Ensure that the Emergency Stop switch is accessible at
all times.
The Emergency Stop switch (1) is on the control near the spreader.
If the Emergency Stop switch (1) is pressed, an emergency stop will be
triggered in which all movement by the spreader will be stopped and all
controls disabled. The vehicle will not be affected by this.
The buzzer indicates to the driver/operator that the Emergency Stop
switch has been pressed. In addition, "Spreader connection" will be
shown on the control panel display.

Warning!
Danger of death by uncontrolled reactivation!
Uncontrolled reactivation may cause serious injuries or death.
Therefore:
•Before switching on again ensure that the cause of the

Danger of death of very serious injuries caused by falling
loads
Lift the spreader only with adequately sized handling equipment
and lifting gear
Do not stand under suspended loads.
When you place the spreader on the load space of the carrier
vehicle, ensure that it is stable
Caution!
