2. PURPOSE OF USE
STARK Road graders are used for grading gravel roads and flat areas and for transferring ice (removal of packed snow).
The device can also be used to shape and align fields.
3. SAFETY PRECAUTIONS
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
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 later 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!

4.1. Identification plate
Identification plate is placed on the side of the equipment. The plate includes contact information, machine type, year of
manufacture, serial number and weight. (See an example of an identification plate in picture 1 below).
The first four numbers in the serial number indicate the month and year of manufacture (month first). The remaining five
numbers constitute the machine tracking number, which is stored in the manufacturer’s database (13971 in the example
below).
Picture 1. Identification plate
Take down the machine type and the serial number of your road grader:
Product and model _______________________________Serial number___________________________________
4.2. Maintenance services
When replacing parts, use original, manufacturer spare parts only. By using original spare parts, you ensure dependable
operation of the road grader and comply with the warranty policy. To facilitate the supply of spare parts, always inform

6. ATTACHING THE ROAD GRADER
When attaching the road grader 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 road grader to a new base machine.
Make sure that the base machine allows installation of the road grader. Minimum requirements of the base machine:
-Minimum weight of 6,000 kg
-without remote controller the hydraulics require 4 pc of 2-action hydraulic valves
-With wireless controller, 1 x 2-way hydraulic valve
-7-pin trailer light plug
-3-pin power socket
-Towing hook
6.1. Attaching the road grader to the base machine
Before using the road grader spreader, MAKE SURE all locking cotters and pins are secured and intact.
When coupling the road grader 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 road grader is connected to the base machine’s towing hook and hydraulic system.
3) Connect the grader to the base machine’s towing hook and move the tractor arms to lower position.
4) Turn off the base machine, engage the parking brake and release pressure from the hydraulic jacks.
5) Connect the hydraulic connectors to the base machine and make sure that the grader does not damage the
cable connectors while in motion.
6) Connect the power socket/plugs.
7) During the first use, exercise extreme caution when using the product and make sure that grader does not
collide with the tractor when in motion. The warranty does not cover damage caused by an improperly installed
device.
8) When the attachment is new, bolts, nuts and connectors can loosen up among first hours of operation.
Retighten them after the first day of operating the attachment.

7. OPERATING THE ROAD GRADER
Before operating the road grader, make sure:
-the road grader is installed correctly
-all locking pins are in place
-hydraulic hoses are connected right and properly
-hoses are intact
-there are no oil leaks
-all functions are working properly
-learn to operate the road grader in a closed area before actually using the device
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 road grader is attached to the towing hook on the base machine. Engage the parking brake. Attach the
road grader to the base machine.
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. Make sure that the
hydraulic hoses and attachments have enough space. If needed change places of the hoses in the base
machine.
6. Stay alert for any abnormal behavior and oil leaks also during driving.
7.2. Grading adjustmets
-Press back-lift cylinder all the way down, then lift it to the transfer position with a synchronized lift. If you do not
press the back-lift cylinder down first, it won’t go all the way up.
-Press the grader down with a synchronized movement. This way both of lift cylinders will move.
-Adjust the main blades so that they will drag evenly with a lift cylinder located on back.
-Adjust the desired slope of the road with a tilt cylinder.
-Adjust the windrow blade to the desired height with wheel’s turnbuckle and lock it.
-Windrow blade is at right height when gravel from the main blades spreads evenly on the windrow blade.
-If needed use the ditch wing available as an accessory. Wing’s descent velocity can be adjusted without steps
with restrictor valve. Open the valve to lower the ditch wing.
-Adjust the driving speed and the drag of the main blades with a synchronized lift to get best results.
Alternatively adjust the height of the tire packer.
-If needed use the tire packer’s rotation to get more width and when dragging on curves (this way the grader can
be kept at own side of the road). Tire packer’s rotation can also be used for tight turns and while reversing.
-When finishing operating the road grader, lift the main blades up with a synchronized lift so that gravel won’t be
transferred to the windrow spreader. Lift the grader to the transferring height after the windrow spreader doesn’t
get more gravel.
-Stay alert for the condition of the blades while operating the grader. If needed, adjust the blades or change
them to new ones.

7.3. Detaching the road grader
-When you disconnect the blade assembly from the tractor, lower the assembly on a flat surface and rest it on
the blades.
-Rest the blades on top of strong support brackets.
-Turn the restrictor valve’s adjustment cap into closed position (picture 3). Lift the ditch wing up with hydraulics,
wing locks upward position hydraulically.
-When transferring road grader for long distances, ditch wing must be secured to upwards stance with e. g. a
cargo strap.
-Turn off the base machine and remove pressure from the hydraulic hoses. This facilitates the re-installation.
-Disconnect the hydraulic quick connectors and sockets and protect them.
-Start the base machine and remove the blade assembly from the tractor hook-up.
