ome operators are known for their slam-bam mode of shifting at the work site.
Problem is, this type of shifting causes lots of unnecessary wear and tear on the

..
Use the road grader’s hydraulic
unloading valve when you start the
vehicle’s engine. When you’re sitting
in the driver’s seat, it’s located on the

your foot off the valve too fast. That forces
too much pressure from the pump into the
system’s main hydraulic lines. The result
is blown seals with lots of leaks.
