Introduction
The iMC system measures the position of the bucket edge using hydraulic cylinder stroke sensors. A bucket cylinder reset is sometimes required to re-synchronize the sensor with the actual cylinder position, especially after system startup, service, or if accuracy seems off.
⚠️ Safety Notes
-
🔴 Always park safely: Lower the bucket to the ground, set the lock lever to LOCK, and stop the engine before beginning.
-
⚠️ Clear the area: Make sure no one is near the work equipment.
-
✅ Perform reset on level ground: This ensures consistent calibration.
Step-by-Step Instructions
-
Prepare the machine
-
Park on firm, level ground.
-
Lower the work equipment fully.
-
Start the engine and let the hydraulic oil warm up to operating temperature if the machine is cold.
-
-
Set the lock lever to FREE
-
Unlock the work equipment control levers so the bucket can be operated.
-
-
Move the bucket cylinder to full stroke
-
Curl the bucket fully until it reaches the mechanical stop.
-
Hold the control lever in the full curl position for about 2 seconds.
-
This tells the system where the end of the bucket cylinder stroke is.
-
-
Release the lever
-
Return the work equipment control lever to the NEUTRAL position.
-
The system stores the cylinder reference point.
-
-
Confirm reset
-
On the ICT monitor, check that the cylinder function caution lamp (if previously lit) clears.
-
Perform a quick position check against a benchmark if possible to confirm accuracy.
-
Tips
-
Do a bucket cylinder reset whenever:
-
The iMC system prompts for it.
-
After hydraulic work or sensor replacement.
-
If the bucket tip display seems offset from actual ground contact.
-
-
You may need to repeat the reset if not held long enough at full stroke.
