Introduction
These operation instructions for the Avant compact screening system are de- signed to help the user
become familiar with the technical details, operating proce-dure, safety precautions and
maintenance to ensure the Avant compact screeningsystem is used safely, correctly and for it`s
intended purpose.
Operating instructions are intended for operators and maintenance personnel.
Operating instructions should be available at the location of the Avant compact screening
system at all times.
This document is based on current information at the time of printing.
Each person working on/with the Avant compact screening system
must;
- Have read and understood these operating instructions before starting work on
the Avant compact screening system.
- Must observe and apply the instructions and safety warnings to the work site.
The Avant compact screening system may only be operated under the condi- tions described
in this manual. Under no circumstances may the specified limit values be exceeded. Your
safety and the safety of others is dependant on your how you operate your Avant compact
screening system.
Intended Purpose
The Avant compact screening system is to be used for the screening, aerating, separating
and mixing of soils, aggregates and compost.
The Avant compact screening system is to be used exclusively for the purpose intended, e.g.
Not to be used as a primary digging bucket. The operator of the Avant compact screening
system is responsible for damage resulting from the Avant compact screening system not
being used for the purpose intended. This also includes following the manufacturer’s
instructions for the operation and maintenance of the Avant compact screening system.

Product Description
Scope
The Avant compact screening system is a bucket type attachment fitted either to a hydraulic
excavator or a wheeled loader replacing the standard digging bucket.
The bucket shell is a steel structure with welded joints, integrated driveline cavities, triple
skin floor and wear resistant cutting edge. The shell has been tested up to 1.5x maximum
permissible load.
The horizontal shafts fitted with Polyurethane flexi-stars that rotate in the same upwards
direction. The rotors are supported at each end by a sealed bearing unit and is driven by a
hydraulic motor via a carbon chain belt and drive pulley system.
The hydraulic motor, driveline and bearings are all housed within the main structure of the
bucket with access via a bolted panel. The hydraulic power is produced by the excavator or
wheeled loader’s hydraulic pump and control system via its auxiliary/option circuit, and is
transferred through by flexible hoses to the Avant compact screening system`s hydraulic
motors.
The Non-Hazardous material to be screened is loaded into the Avant compact screening
system in the same manner as a standard excavator or wheeled loader bucket. Once the
bucket has been loaded with material to be screened and positioned, the excavator or
wheeled loaders auxiliary hydraulic circuit is activated causing the star rotors to turn in an
upwards direction.
The efficient screening process is created by the star rotors agitating the material, causing
the fines to flow through the rotating stars leaving the oversize material in the bucket.
Once the screening process is completed the oversize material is tipped out and the
process is repeated.
