1. Scope
The GYRU-STAR Screening bucket is a bucket type attachment fitted either to
a hydraulic excavator or a wheeled loader replacing the standard digging
bucket.
The GYRU-STAR Screening bucket shell is a steel structure with welded joints,
integrated driveline cavities, double skin floor, and with a wear resistant cutting
edge. The shell has been tested to 1.5x maximum permissible load.
The horizontal shafts fitted with Polypropylene flexi-stars rotating in the same
upwards direction. The rotors are supported at each end by a seal bearing unit
and is driven by a hydraulic motor via a carbon chain belt and dive pulleys
system.
The hydraulic motor, driveline and bearings are housed within the main
structure of the bucket with access via a bolted access panel. The hydraulic
power is produced by the hydraulic excavator or wheeled loader hydraulic pump
and control system via its auxiliary/option circuit and transferred through by
flexible hoses to the GYRU-STAR Screening bucket hydraulic motor(s).
The Non Hazardous material to be screened is loaded in to the, GYRU-STAR
Screening bucket in the same manner as the standard excavator or wheeled
loader bucket; once the bucket has been loaded with marital to be screened and
positioned the excavator or wheeled loaders auxiliary hydraulic circuit is
activated causing the star rotors to turn in upwards direction.
The GYRU-STAR Screening bucket efficient screening process is created by
rotating 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.

3. Safety Instructions
WARNING
Special attention must always be paid to the safe use and maintenance of the
GYRU-STAR Screening bucket.
The GYRU-STAR Screening bucket should only be used by a trained and
competent operator and must have read and understood the operator’s manual
before operating the GYRU-STAR Screening bucket.
Before operating the operator must ensure the GYRU-STAR Screening bucket
is suitable for the carrier and ensuring when fully loaded it does not exceed the
carriers’ safe working capacity
Before operating the GYRU-STAR screening bucket the operator must ensure it
is fitted correctly to the excavator or wheel loader, ensuring all locking devices,
mounting pins and hydraulic connections are made correctly.
Before operating GYRU-STAR Screening bucket the operator must carry out a
visual inspection of the general condition of the bucket and the hydraulic hoses,
Ensuring all guards are fitted and are in good order. Any defects are to be
reported and rectified.
Always detach and store the GYRU-STAR Screening bucket on a firm level
surface.
Do not carry out any inspections, maintenance, adjustments, or cleaning until
the excavator or wheeled loader is stopped and the auxiliary hydraulics are
isolated.
Do not leave the excavator or wheeled loader while the rotor are turning.
Do not go under GYRU-STAR Screening bucket in any circumstances.
Allow hydraulic oil to cool down and any pressures to decay. Always wear
correct PPE before disconnection hydraulic hoses.
Always ensure a safe working area of 10 meters in case of flying material.
Before operating the GYRU-STAR Screening bucket ensure all guards are
fitted securely and all safety decals are in good order.

Do not use to lift GYRU-STAR Screening bucket or carry persons in the
bucket.
Only use the for its GYRU-STAR Screening bucket intended purpose of
screening, separating and mixing of soils, aggregates and aeration compost.
The operator must wear appropriate PPE (hard hat and safety glasses) when
used with a carrier without a full operators cabin.
