Make sure you know your equipment before you start using it. Equipment may be operated only
by an individual who is thoroughly familiar with its use.
Before connecting hydraulics to the base machine, make sure that:
-there is no-one between the attachment and the base machine
-the base machine is turned off and the parking brake is on.
When coupling the attachment to the base machine, make sure that:
-all locking cotters are intact and in order
-hydraulic hoses are intact
-there is no skin contact to hydraulic oil when connecting hydraulic hoses
-you do not to pull by the hydraulic hoses, but only by the hydraulic fitting.
During operation, pay attention to:
-safe, appropriate travel speed
-other traffic, people and animals
-danger zones and objects that block your view
-children
-use of turn signal when driving
NEVER use the machine, if there is someone in the danger zone
NEVER go under the attachment
WARNING! Rotating rollers!
During maintenance, the hydraulics of the base machine MUST be turned off. The base machine MUST also be turned
off and the parking brake MUST be applied. The equipment must be properly supported, if maintenance can only be
performed by going under the equipment. Never go under the equipment if it is not properly supported.
Daily maintenance:
-check general condition of structures, make repairs if needed
-check the hydraulic hoses and fittings, and replace damaged parts
After every 50 hours of operation:
-lubricate points specified in the product specific section of this manual
-check all bolts and nuts for tightness
Check all bolts, nuts and hydraulic fittings for tightness after the first day of operation!
If the equipment is not likely to be used for a longer period, clean it thoroughly after use and lubricate as instructed.
WARNING! Pressurized hydraulic hoses and components!

6. ATTACHING THE BUCKET SPREADER
When attaching the bucket spreader 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.
6.1. Attaching the bucket spreader to a base machine
The bucket spreader is attached to the base machine by welded or bolted STARK FIT quick hitches. The machine is
connected to a hydraulic system. Hydraulic circuit diagrams can be found in a later section in this manual. Ask your
retailer for available STARK FIT quick hitches.
Before using the bucket spreader, MAKE SURE all locking cotters and pins are secured and intact.
When coupling the bucket spreader 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. The bucket spreader is attached to the coupler on the base machine (e.g. a loader). Attach the bucket spreader to the
base machine, and make sure the locking cotters and pins are secured. Apply parking brake.
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 attachment’s, the base machine’s and the fitting’s trajectory for collision. Do a test run using the
base machine and the loader in extreme position to check that the bucket won’t collide with base machine. Make sure
that the hydraulic hoses and attachments have enough space. If needed change the location of hoses in the base
machine.
6. 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
Before using the bucket spreader, make sure:
-the bucket spreader is installed correctly
-all locking pins are in place
-hydraulic hoses are connected properly
-hoses are intact
-there are no oil leaks
-all functions are working properly
7.1. Operating instructions
1. Make sure that the attachment and the base machine are compatible in terms of mechanical solutions,
hydraulics and electricity
2. The bucket spreader is attached to the coupler on the base machine (e.g. a loader). Attach the bucket spreader
to the base machine, and make sure the locking cotters and pins 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 the attachment’s, the base machine’s and the fitting’s trajectory for collision. Make sure that the hydraulic
hoses and attachments have enough space.
6. Push the bucket spreader to the sandpile slowly and turn the bucket up with the loader. Work with careful,
steady movements in order to avoid damage to the bucket or the base machine.
7. When using a 3-point filling cylinder, slow down the cylinder movement in order to avoid damage to the bucket
or the base machine.
8. Adjust the flow of sand by a flow control valve, engine’s rotational speed and driving speed so it is appropriate
in the working area.
9. Stay alert for any abnormal behavior and oil leaks also during driving.

7.2. Adjusting the sanding roller rubber
The sanding roller rubber is a wear part. Make sure to check its condition and tightness before the winter season.
Adjusting of the sanding roller rubber:
-loosen the fixing bolts of the protective plates,
-push the rubber out of the opening (e.g. with a screwdriver) firmly against the discharge shaft (Picture 3).
-Tighten the bolts of protective plates to the correct torque. The worn rubber can be turned around.
Picture 3. Adjusting the sanding roller rubber

Sivu 11 / 17
7.3. Adjusting the chain
The spreader roll and the mixing shaft are operated by a hydraulic engine chain. The chain needs to be checked for
tightness every 50 hours of operation to make sure that the bucket spreader works properly. Remove the protective cap
and press the chain e.g. with a screwdriver with a force of 25 kg. If the chain gives in more than 5-10mm, it needs to be
tightened (Picture 4).
Tightening the chain:
-Loosen the tightening nuts
-Adjust the chain with a chain tightener
-Tighten the nuts to the right torque (table 1)
NOTE! The chain can be adjusted without opening engine’s case. However, if you must open the protective lid of the
engine case, seal it off with adhesive paste when closing. This way dust or dirt does not damage the chain.

7.4. Detaching the bucket spreader
1. Lower the bucket spreader to an even ground.
2. Turn off the base machine, put on the parking brake and release pressure from the system
3. Detach the hydraulic hoses and protect the couplings with plugs
4. Open the mechanical lock and loosen the bucket spreader
5. If the bucket spreader is left unused for a long period of time, it needs to be clean and lubricated properly before
storage.
7.5. Transferring the bucket spreader
Lift the bucket spreader high enough and reduce speed if needed, especially on bumby, uneven roads. The bucket
spreader or the base machine can be damaged due to excessive speed.
7.6. Bucket spreader accessories
The following accessories are available for the bucket spreader:
-Filling cylinder with a lock valve
-Hot-dip galvanisation
-Remote controlled flow control valve
-Vibration device

9. HYDRAULICS
The bucket spreader is attached to the base machine with 2-hose hydraulics (chart 1). The system has been tested and
adjusted by the manufacturer. Any alterations or modifications to the hydraulic system are on the sole responsibility of
the client.
Max. pressure: 120 bar
Max. oil flow: 120 l/min.
Max. counter pressure for returning oil 75 bar
The Bucket Spreader has a double pressure relief valve, with a pressure setting of 120 bar. Higher pressure adjustment
is strictly prohibited. Max. allowed oil flow is 120l / min. A larger flow controller is required for higher oil flow from
the base machine. Please contact STARK spare parts sales!
Due to counter pressure in the return line, some oil may leak in the Bucket spreader motor housing (this may damage
the engine sealing). Open and drain the leaking oil out of the housing every 80 hours (Picture 7).
The maximum counter pressure of the returning oil from the Bucket Spreader is 75 bar, depending on speed (chart 2).
