Crown FC-4000:
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
The concept of Daylight Saving Time (DST) was first implemented in Port Arthur, Ontario, Canada in 1908. The first proposal for DST, however, came in 1895 from New Zealand entomologist George Hudson who valued extra daylight so that he could hunt bugs after work during the summer months. He suggested a two-hour daylight-saving shift.
