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

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 attach
ment’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.

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 with
out 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 packe
r’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 blade
s 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.
