Service Inspection Report

Graphic, Volvo Service Inspection Report

When a service is carried out, we recommend that the service points which have been inspected and faults which have been remedied are noted on the service inspection report so that the service for each bus can be followed-up.

Service inspection reports are available for the following:

-Delivery and Warranty Service 1 and 2.
-Operation-reliability checks, lube service and checks every 6 months/checks every 12 months.

The following symbols are used in the Service Maintenance Programme:

Note 1: The service points for the operation-reliability check must also be covered at the 6 and 12 months' checks. Italic numbers refer to numbered items on the inspection report.

Tightness checks

Graphic, under bus

Any dirt on the chassis, engine and power transmission should be removed before servicing the bus. However, leakage is easier to discover before washing and cleaning. Note that there is a difference between leakage and sweating from an oil sealing ring. If there is leakage, very often the oil collects in a drop form.

Important: The top side of a horizontal engine should be kept clean. This is particularly important in the warm season.
