The float is not adjustable. I've used the superior switch (link below) for similar type of pumps. I just secure the original pump float in a permanent on position with a tie wrap. I do this when the OEM pump switches begin to fail, which they are notorious (the infamous rigid lifetime warranty fiasco).

as you say this unit has not been used for years
possible cause for not working : when battery are not used for long time it almost impossible to recharge them .
if you plug is fitted with fuse check for corrosion at the fitting point also check that fuse it ok.
most probably is that the impeller of the pump is jammed where corrosion has taken place and or if left unclean when last used (years back ) the slug may well stops it from spinning

Isolate the pump from the electricity supply...!!!!

Could be a fault with the windings or the electrical connection. As you're getting a shock, that's the first place to look. If water is getting into the electrical side then the seals have failed and you might need to replace it...

The float is sticking when you are not observing its action. I have had the same experience.

Pump not working or float stuck. Most don't have an alarm hooked up, go by the light. And call someone to check the pump.

Replace the battery first. It is cheaper than a whole pump. The battery is constantly being charged and will go bad after time even though it does not get used.

Make sure the impeller is as clean and clear as possible, anything clogging it and restricting its rotation will cause it to blow a fuse. If tis not turning easily and feely most likely the bearing is starting ti seize up.

You install two wires at the two terminals on the float switch to a switch so that when the switch is toggled the wires will act like the float switch has closed and make the pump operate.

If there is a door that opens to set or make adjustments on the unit, check to see if there is a screw in that area to possibly gain access to the battery compartment. Or check their website for a manual.
