Lift/tilt not working

I have a 2011 Crown Fc4000, forklift sat low battery not being used for about two months, finally got her charged up, running fine, but lift hydraulics aren't working properly.

First observed very slow lifting with a sputtering sound, tried to cycle it up and down in case it was air in the system, noticed faint smoke so stopped use. Tried to troubleshoot today, sometimes it will sputter/lift, sometimes it will just click and not lift at all.

Any advice appreciated. Thanks in advanced

Check hydraulic fluid could be cavitating from low fluid.

Do you have a meter attached to the battery, so that you can view battery voltage while energizing the Lift Motor ?

What voltage do you see ?

Check the brushes in the lift motor. Make sure they are not worn or stuck in the brush holder.

Fact of the week
At the opening ceremony of the Sydney Harbour Bridge in 1932, marching bands were instructed to walk out of step as they crossed the bridge. This unusual directive was given as a precaution due to concerns about the bridge's structural integrity during its early use.
