Servicing generators, switching out filters making sure they were still good and if they needed to be replaced I would change it out for a new one also making sure they had enough oil in them before turning them on watching the levels on them , checking the batteries and making sure the volts are still active before wiring. GPS to the computer so we could track which generator was down
Inspected drill pipes when they came in reface the pipes making sure they we were ready to be sent down into the ground UT the pipes to check the thickness of the walls
