This is a flat rate manual, or service pricing guide (JD-19) and does not give any actual service information.  It gives you a time schedule telling  how long it should
take to complete a job on the listed equipment.  This manual would be helpful to verify the hours you are being charged for labor, or to figure how many hours to charge for a job you are doing.  It covers 320, 330, 420, 430, 435, 440I, 440ID, 520, 530, 620, 630, 720, 730, 720D, 730D, 820, and 830.  Slightly worn and stained from shop use but still in good condition.
