Default Forklift mast not going up properly

When I go up with the forklift mast the first stage goes up about half way and then the second starts lifting.

This just started. What could cause this?

First guess is lack of lubrication. Lube the moving parts, put some weight on it and try again.

I'm assuming this occurs with no load any kind of load should make a multi-stage cylinder behave correctly. Culprits bent cylinder rams, seals fucked up, forklift tower screwed up. Pay attention for noises signs of binding Etc.

Yes, but...
I have the same size machine, and I faithfully greased the shit out of it. And one day I noticed how well that grease collected grit from my grinding wheels and metal shards from the angle grinder. I found out by wiping some grease from the mast off my hand and inbedding shards of metal shavings in my hand.

So I pressure washed it all off as best I could and used a bit of Fluid Film, coupled with twice yearly pressure washing.

I just said it looked a little dry. As in NO lubrication. I'm not a fan of excessive grease either...

The spray white lithium is a good lube and dries so crap will not stick.
