Safety lock parts
1. Safety lock
Warning: the safety lock mechanism of the attachment is an important part
of the machine safety system. Safety lock must be enabled before the driver
leaving the cab. If the left control box is not in the locked position, the
handle may move, causing the working device or platform to move, which
may result in an accident.
Lift the left control box to the locked position,
the general control of the pilot system does
not supply oil, and the machine working
device and platform rotation can not work
(except for left and right travel control, dozer
blade), which plays a role in safety
protection.
Lower the control box and press it to the
bottom to the free position, the pilot system is
connected to the oil pressure source, and the
machine can work normally.
