Your Apeks set is dead easy to service(DIY) as there is no special tool required. Service kit for both 1st and 2nd stage is your only concern.
Intermediate pressure gauge(IPG) is dirt cheap and every diver should has one to monitor their own regulators.
Your set sounds ok to dive and you should use the IPG to monitor it before or after every trip.
I believe 9.5 bar is the pre set value for your set any slow drift upward is the time to service the regs.
