Introduction
A position check ensures the ICT/iMC system is correctly calibrated. You compare the bucket edge reading on the ICT monitor against a known survey control point or benchmark. If it matches, the system is ready for accurate grading.
⚠️ Safety Notes
-
🔴 Do not perform this check while swinging or traveling. Always stop the machine first.
-
⚠️ Stay clear of the bucket edge while measuring. Use a survey rod or spotter if needed.
-
✅ If accuracy is off, do not dig until you re-calibrate or adjust.
Step-by-Step Instructions
-
Prepare the machine
-
Park on firm, level ground.
-
Lower the bucket near the benchmark location.
-
Turn the starting switch to ON and allow the ICT monitor to boot.
-
-
Select the active project file
-
From the ICT monitor menu:
-
File → Project File → Change Active
-
-
Make sure the correct site/project file is active.
-
-
Set the correct design surface
-
Go to: File → Active Design Data
-
Confirm the proper surface/alignment is active.
-
-
Move the bucket tip to a benchmark
-
Place the cutting edge or bucket tooth on a known control point (survey stake, benchmark, or measured point).
-
Make sure the bucket is square to the ground, not tilted.
-
-
Read the display
-
On the ICT monitor, the system will show the bucket edge elevation and offset relative to the design surface.
-
Compare this with the known benchmark elevation.
-
-
Evaluate accuracy
-
If the difference is within tolerance (e.g., ±20 mm for rough grading, tighter for finish work), the system is good.
-
If not, proceed to adjustments:
-
Re-check cutting edge wear settings.
-
Ensure GNSS correction source (radio/NTRIP) is connected and stable.
-
Perform bucket cylinder reset if required.
-
If still inaccurate contact your distributor. Komatsu Australia Smart Construction Support Centre.

-
Tips
-
Do a position check at the start of each shift or when moving to a new job site.
-
Repeat checks periodically during the day, especially if accuracy “feels off.”
-
If satellites are low or obstructed (trees, buildings), the system may show GNSS: Low Accuracy — wait for better reception.
Conclusion
Performing a position check on the iMC system gives you confidence that the bucket is digging to the design surface. If readings don’t match your benchmark, fix the error before you start work to avoid costly rework.
