Jensen A528t

[ajc]

Hi, I've got a jenen A528t and the feed rollers are stuck reverse? Help please. We havent had a jensen before so I presume the 2 switches on the hopper are one is forward and the other is reverse??

have you got manual with it !!!!!!! the stickers on the machine should point you in the right direction

Check the spool valve on the right hand side of the hopper is still connected to the bar which goes to the infeed control bar, this could have snapped leaving it in reverse.

 

Check the circuit board under the hood, sometimes it's as simple as a loose wire, mine has done this.

 

Bald Ed on here is very good with Jensen chippers, may be worth pm'ing him.

 

To add, if it still has those big yellow round buttons on it they can cause a bit of hassle, mine have been disconected due to problems, works fine now with just the bar.

What do the big yellow buttons do are they stop buttons or direction?

Sometimes the pivot pin in the valve drops out leaving the spool stuck at whatever position it was in.

I beleive they are emergency stop/reverse buttons, i dont think the modern Jensens have that feature anymore.

They are re-set buttons mate. When you stop the rollers with the bar you have to press either button to engage the rollers again.

If you are having problems give charles a ring 07967 263503, he is a mobile chipper engineer and would be pleased to help.

All sound advice so far. Same with any problem tho, keep calm and logical, check the cheep fixes first like wiring/connections, check that the nipple is indeed moving the spool before panicing.
