By analyzing the product's response to such tests, engineers can make prediction about the service life and maintenance intervals of a product.
If permanently moored in fresh water the maintenance interval can be extended to 25 years.
One of the technologies that enables this long maintenance interval is the distributorless ignition.
They changed the maintenance interval, and developed and sold a special tool for 'proper' valve-lash adjustment.
This leads to more frequent maintenance intervals for the pistons, piston rings, and cylinder walls.
The shade not only reduces emissions, but reduces shrinking and cracking so that maintenance intervals can be lengthened.
By contrast, laser printers do not have printheads to clog or replace frequently, and usually can produce many more pages between maintenance intervals.
October 2008 and the maintenance intervals were drastically reduced which lead to major service disruptions.
There are regulations for checking equipment and regular maintenance intervals will be set.
The intensity, in particular, is being neglected on cost grounds, and maintenance intervals are being lengthened.
