Suspension light indicating on dashboard

If the suspension light is indicating on the dashboard of a Grove GMK 3050-1, it may suggest that the oil level in one or more suspension struts is too low. The maintenance manual states that the oil level on the inspection glass of the suspension struts should be checked monthly. If the level is too low, oil must be topped up using the press and hose provided in the tool box. Regular maintenance is required to ensure proper suspension function.
