My glm relay stopped working after I put my exam table on a piano dolly to move to another room while the hydralics were worked on.  Any thoughts .  Could oil have spilled o it  and caused it to malfunction?  I can manually push it and hold it and it allows the table foot pedals to operate.  any ideas how to keep it working without doing this.  i need a replacement metal tray for my table  anyone have one to sell?

Please help finding me one. Thanks
