My new 308D SB has spent more time at CAT than with me. They found a fix for tracking power, which it had none, now it pushes like a dozer. It will not swing a bucket full of material up a grade and runs out of hydraulic flow when multi functioning. They replaced the swing motor not any better. Dealer just got 2 new machines in with the same issue. Do I really need to bench it in on a level pad in order to work? Nobody use their machines on a slope? Any body else with 308 issues.
