users.
Before connecting hydraulics to the device, please check:
-there is no one between the attachment and base machine
-the base machine is turned off and the parking brake is on
When connecting the attachment to base machine, please pay attention:
-that the locking pins and cotter pins are fine
-there is no pressure in the hydraulics system
-that the hydraulic hoses are intact
-when connecting the hydraulics avoid skin contact with hydraulic fluid
-do not pull from the hose, only from the hydraulic fitting
While operating, please pay attention:
-safe and appropriate speed
-other traffic, people and animals
-danger zones and visual obstacles
-device should not be used when someone is in the danger zone
-be careful around children
-use flashing light while operating the machine
-do not go under the device
While servicing the device, the base machine’s hydraulics must be switched off, the base machine turned off and the
parking brake put on. The device must be lowered on supports if going under the device is required. Never go under the
device if it is not supported.
Daily maintenance:
-check the overall condition of structures, make repairs if needed
-check the condition of hydraulic hoses and couplings, change if damaged
Maintenance every 50 hours:
-lubricate the lubrication points (locations are given in product specific section)
-check the tightness of the bolts and nuts
Check the tightness of hydraulic connectors, bolts and nuts after first eight hours of use!
If the device is left unused for a long time, it needs to be cleaned well and lubricated before storage.
BEWARE pressurized hydraulic hoses and components!

6. USING THE ROTATING DEVICE
When attaching the device for the first time, make sure it is compatible with the base machine by following the
instructions below. Always check the compatibility when attaching the bucket spreader to a new base machine.
Rotating device is attached to base machine by bolt-on STARK FIT quick hitcher system. Base machine fit is bolted on
to bracket.
Remember to properly mount the hydraulic hoses from Rotating device to base machine!
6.1. Attaching the rotating device to a base machine
The machine is connected to a hydraulic system. Hydraulic circuit diagrams can be found in a later section in this
manual. Before using the bucket sweeper, MAKE SURE all locking cotters are secured and intact.
When coupling the bucket sweeper to the base machine, please pay attention to the instructions on the use of the base
machine.
1. Make sure that the attachment and the base machine are compatible in terms of mechanical solutions,
hydraulics and electricity.
2. Apply parking brake. The bucket sweeper is attached to the coupler on the base machine (e.g. a loader). Attach
the bucket sweeper to the base machine, and make sure the locking cotters are secured.
3. Turn off the base machine and make sure the parking brake is applied.
4. Make sure there is no pressure in the base machine hydraulic system. When connecting, always make sure the
hydraulic connectors are clean and the hoses are intact.
5. Check carefully the movement paths between the coupling mechanism, the base machine and the attachment
for collisions. Check also the space needed for hydraulic hoses and connectors.
6. Rotating device needs one double-action hydraulic valve to operate. In bucket sweeper is equipped with two-
hose hydraulic system and Rotating device/ Bucket Sweeper combination is also needed to be maintained
suitable to two-hose hydraulic system, functions can be operated with optional electrical hydraulic valve. In this
case, one function is operating the bucket sweeper as before and second function is turning Rotating device.
7. During first hours of operating the attachment, bolts, nuts and connectors might loosen up. Retighten them
after the first day of operating the attachment.

7. OPERATING THE BUCKET SPREADER
Check before driving, that:
-the machine is correctly installed
-all locking pins are in place
-hydraulic connectors are correctly installed
-hoses are intact
-there are no oil leaks
-all functions work properly
-learn to use the rotating device on closed area before actual usage
7.1. Using the Rotating device
1. Check that the attachment and the base machine are compatible in terms of mechanical solutions, hydraulics
and electricity.
2. The bucket sweeper is connected to the base machine’s quick hitching (e.g. front loader). Apply the parking
brake. Connect the bucket sweeper to the base machine and make sure the pins are properly locked.
3. Turn off the base machine and make sure the parking brake is applied.
4. Make sure there is no pressure in the base machine hydraulic system. When installing, always check that the
hydraulic fittings are clean, and hoses are intact.
5. When mounting Rotating device to bucket sweeper, lifting arm movement must be restricted by installing
limiting cylinders inside lifting cylinders in aftermarket installations.
6. When ordering combination of bucket sweeper and rotating device from the factory, lifting arm are already
limited.
7. Make sure, that watering system manifold is installed below the main beam, as shown in picture 3.
Picture 3. Watering system manifold correct position

7.2. Adjusting the safety mechanism
Picture 4. Safety mechanism adjusting bolts (6pcs).
Rotating device is equipped with safety mechanism which will protect rotating gear in case of possible collision.
Adjustment bolts (shown in picture 5) are tightened on factory to 20Nm, that should not be changed without reason. Due
usage of the rotating device, the safety bolts may be needed to re-tighten to 20Nm. Bolts can be tightened by opening
locking nuts, tightening bolts and then re-tightening locking nuts. There are 6 bolts and nuts in total.
Tightening the bolts over 20Nm tightening torque will cause expiry of warranty regarding Rotating gear.
Rotating device damaged by overtightening the bolts is not covered by warranty.
