Default onan transfer switch

I have a model # OTUDD225-4/120/C transfer switch that will not engage in auto mode when power is lost. The linear actuator shutters , so its receiving a signal, but will not fully throw unless helped manually. Can the actuator be removed and cleaned, lubricated, etc to help or does it need to be replaced?
The actuator is a - Innovey inc. # A02-12-02.
Please help!!

Need your full model and serial number.

Could be several reasons for the problem.They did have a problem with some motors getting out of alignment. You should be able transfer it with one finger on the arms. It should slide that easy. I would kill the power to it. Then try moving it. That is a short duration motor so don't let the power stay on to long. It will burn up.

There could also be a problem with the micro switches or the breaker for the motor.Post an email address someone will send you a service manual.

Yes you can remove and clean it. Don't grease it.

model # -OTUDD225-4/120/c
S/N - I790447332
actuator part # A02-12-02
It takes a lot of force to manually throw the actuator arm , simalar to a large 3 pole main breaker.

Do you have access to pages 42- 46 , checking and replacing of linear actuator? Takes alot of force to switch in the manual mode, power is on when I try this. Would that have an impact? Previous post states it should move with ease, not so with this, almost takes 2 hands.

Don't do that with power on. It can break your wrist. You are fighting the motor and you will lose. Turn the power off to move it. There should be a motor disconnect switch in place. Turn it off. It is possible that the plastic guide for the transfer rod is melted.
