This machine is a 2006 Raymond Electric Pallet Jack, model 830-F60L S/N 830-06-66475. The Arm does not move to the left or right? The motor is working and the drive wheel moves forward and backward. But when I pull the arm down it does not move to the left or right, maybe 1/4" max so my machine will go forward but goes straight and I can not turn it. I have ask this question before but to solution has not been found yet. I bought this unit as is, so I don't know what this problem could be. It really makes me thing that it is an electrical problem but I just don't know. The arm casing at the bottom looks sealed like nothing could get in it, but maybe something is hanging it up? Before I open this up, could it be electrical problem like a default or what else can it be? The Curtis controller on this machine shows 7 blinking lights and 2 red blinking lights and continues that way.

Thank you both, I think you are right about the bearings starting to seize up. I didn't read your post until now and about an hour ago I decided to man handle it and pull it to the right and it worked so I pulled it to the left hard and it worked. I started driving the unit around the shop move the handle every direction and it really turn fine now. I think the bearing had rust in them and I may have broke it up. Thanks for your import. Now I have to figure out why it does lift up or down.
You stated that it will travel, but will not turn. Can you elevate the drive wheel and attempt to turn the handle? In doing this, if there is strain on the steering bearing, it will be relieved. Also, look around the bearing that mounts the drive unit to the frame of the truck. Do you see a grease fitting, like a zirk or needle fitting? If not, then the problem will be the bearing that I have been talking about. When that bearing was put on this serial number range of trucks, the "powers that be" believed that there would be no need to grease the bearing, since it was sealed. After many trucks ran in a cold storage environment, the bearings started seizing, consequentially resulting in a service bulletin to be published recommending the bearing to be replaced with one that DOES have a grease fitting. As for the code, are the red lights flashing first? and how many flashes from the yellow lights? This code flashing on the traction amplifier has no effect on the steering problem you are encountering. Sorry for the history lesson and for being so long with this reply. I don't have a lot of time to get on this forum much, so I tend to go overboard. Hope this helps!
To be sure, this is manual steering correct? No power assist?
When jacked up, can you turn the steering now? With handle up or down?
It's a very simple manual steering drive unit. If you cant turn it, the radial rings are seized. That's all folks!
They are sealed units from the factory and have no grease fittings. Water can enter them over time and will seize them solid.
