HANDLE KOMATSU TRACTION CONTROL SYSTEM
(KTCS)
WARNING
• KTCS is enabled when “KTCS Setting” is set to "ON".
• When the system cannot be properly controlled due to a trouble in the system, the machine monitor
displays an action level and the system may stop operation depending on the failure condition.
• The machine may not travel safely on an extremely slippery road or on a steep slope even if the
KTCS operates.
• If a wheel is stuck in the ground and the machine cannot escape while the KTCS operates, pull out
the machine with a bulldozer, etc.
KTCS is a system to prevent the drive wheels from slipping caused by excessive torque and improves starting
and traveling ability on the soft or slippery ground.
OPERATION OF KTCS
The KTCS is ready to start the control when “KTCS Setting” is
“ON”.
When the KTCS detects the rear wheel slipping, the KTCS
starts the control and the KTCS pilot lamp lights up.
