A new MS40LI or one that has been in storage for a time may not pump unless the priming bulb is depressed several times.  This brings liquid to the pump and the pump will then pump.
The priming bulb can be found between the back pad and the back of the tank on the left hand side.  Priming instructions are on the top of page 8 in the manual. Read the owner’s manual for additional information.
Caution! Do Not run the pump without water as pump failure can result.
