1.10 Operator Presence Sensing (option)
OPS (Operator Presence Sensing) system is a safeguard system that installs a sensor in the driver
seat to sense if the driver sits on the seat correctly. If the driver does not sit on the seat correctly,
driving force is cut off, meanwhile, all loading and unloading operations will be stopped. It helps to
reduce accident when the driver leaves. When the driver does not sit correctly, the driver cannot
drive the truck or operate the loading and unloading, thereby reduce safety accidents caused by
misoperation.
