Hydraulic pump had overheated????

We have a 2014 3100RL Montana 5th wheel with six-point stabilizing jacks. The other day because we had trouble hooking up, we raised and lowered the front of the 5th wheel a number of times. After a while the stabilizing jacks stop working. The relay leading to the hydraulic pump was operating correctly with 12 V on the correct terminals for the up/down terminal as appropriate. After about 10 minutes everything worked okay.

It appeared the hydraulic pump had overheated. Is this normal? Is there a manual override?
