Description of Change:

------ WARNING! ------

Personal injury can result from flame cutting or welding on painted areas.

The effect of gasses from burned paint is a hazard to the person doing the cutting or welding.

Do not flame cut or weld on painted areas.


------ WARNING! ------

Personal injury or death can result from fumes, gases and ultraviolet rays from the weld arc.

Welding can cause fumes, burn skin and produce ultraviolet rays.

Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing area. Wear eye, ear and body protection before working.

Protect yourself and others; read and understand this warning. Fumes and gases can be dangerous to your health. Ultraviolet rays from the weld arc can injure eyes and burn skin. Electric shock can cause death.

Read and understand the manufacturer's instructions and your employer's safety practices. Do not touch live electrical parts.

The D6G Series II XL Track-Type Tractors that are equipped with a 9C-4449 Seat Gp have the 9V-7446 Armrest As that could not be adjusted. This may make the operator feel uncomfortable when operating the hydraulic implement handle and transmission handle.

Adaptable To: The operator environment was designed for the D6G Series II and D7G Series II to cover the 95 percentage in standards. At the same time, the existing armrest could also not be adjusted. Some operators might feel uncomfortable when operating the steering clutches and blade implement levers. Install the adjustable armrest by using the parts that are found in the table below.
