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!

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
-With wireless controller, 1 x 2-way hydraulic valve
-7-pin trailer light plug
-3-pin power socket
-Towing hook
-Hydraulic output max. 50 L /min and 210 bar
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 tractor’s towing hook and hydraulic system.
3) Turn off the base machine, engage the parking brake and release pressure from the hydraulic jacks.
4) Connect the grader to the base machine’s towing hook and move the tractor arms to lower position.
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
Grader is equipped with a remote controller, which allows to control all actions with one 2-way section valve. Controller,
it’s fastener and power socket are added to the base machine.
Operating the controller:
-Attach electricity from the base machine with a 3-pin power socket.
-Turn the controller on with a green START-button (must be done every time the power supply stops).
-Operate controllers’ buttons simultaneously with the base machine’s directional valve.
-When transferring the grader turn off the controller with a red STOP-button.
-The warning light of the controller lights up 100 hours before the batteries are empty.
-If there is an error in controller, recode it.
Functions of the controller (picture 3):
-Main blades of the grader lift/descent with buttons 1 and 2. When transferring the road grader keep main
blades all the way up.
-Main blades’tilt can be adjusted with buttons 13/14 and 11/12. Use slope pointer to check the slope of the
grader.
-Windrow blade lifts/descents with arrow buttons of controller box. When transferring the road grader keep
windrow spreader all the way up.
-Windrow blade’s tilt can be adjusted with buttons 5/6 and 7/8. Windrow’s height depends on the depth of the
grading. If there is sand coming out of windrow blade, it is too close to the road. Windrow spreader is adjusted
correctly when rocks come out of windrow blade and transferred material spreads evenly on the road.
-Width of the windrow blade can be adjusted with buttons 9 and 10.
-If grader is equipped with side blade, it can be adjusted with buttons 3 and 4. When transferring the road
grader keep side blades all the way up.

7.3. Adjusting the blades
Edge of the blade should be 15–45 mm lower than the blade frame. Blades need to be adjusted at the latest when the
blade edge is less than 10 mm lower than the blade frame (picture 4). Do not adjust the blades more than 50 mm lower
than the blade frame.
Picture 4. Minimum distance of the blade to the frame
Blades can be adjusted three times. Each time there will be about 45 mm wear edge on the blade. First when the blade
is new, it is in the position of picture 5. When the blade edge wears out it is lowered and attached from the upper holes
of the blade (picture 6). Next time the blade is turned and again attached from the lower holes (picture 7). When the
blade edge wears out again it is lowered by attaching it from the upper holes (picture 8). When the blade edge wears out
in this position, it needs to be replaced.

the blades.
-Rest the blades on top of strong support brackets.
-When transferring road grader for long distances, windrow spreader 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 tractor and remove the blade assembly from the tractor hook-up.
7.5. Accessories
The following accessories are available for the road grader:
-Flat-, pin- and hardened metal blade set
