Hi - new user here with a troublesome L12. Mechanically trained but I have no knowledge of materials handling equipment.

Purchased used a few months ago for my small business use. All been fine but a few weeks ago the drive would not activate every time. Turning it off and on would reactivate it and it would then carry on fine for a number of uses. Now it is completely stationery but holding down the bump stop on the tiller end does cause it to drive forward. Lift up and down is fine too.

Any suggestions for fault finding would be appreciated. Thank you.
