Keeping the prep lab equipment running properly is everyone's priority. Expensive equipment cannot always be replaced immediately, so in order to keep our equipment lasting as long as possible, please follow the instructions for cleaning and routine care of equipment.

Behind the garden by the main door is a large storage shed. The door to the shed is not locked, so anyone can access it when they need too. Please use caution, as bees and wasps have been known to use this area to build their nests here.
When running the compressed air on a humid day, a lot of moisture builds up inside the air tank. If left unattended, this moisture will rust a hole though the holding tank causing the compressor to fail. Replacement for compressed air units of this capacity run upwards of $3,000-$7,000 (2016 prices). Needless to say, if this unit fails it will be a bit before NPL can absorb that sort of expense!
To drain the holding tank, just turn the handle to the 'open' position. Leave it open until moisture stops rushing out, then close it all the way . Leaving the drainage pipe open will result in insufficient pressure to run air scribes or abrasion units. If you notice very low pressure, or if you hear the compressor constantly running, please go check the drainage pipe. |

Air scribes, more than any other tool in the prep lab, are prone to getting 'gunked up' beyond all belief. Trapped bits of matrix mix with pneumatic tool oil to create a perfect sludge for eroding bushings, pitting O rings and wreaking havoc on the precise movements of the stylus. To avoid such issues, it become necessary to field strip and clean the scribes from time to time. As NPL does not currently use the scribes heavilyon a regular basis, a maintenance schedule is not required. In lieu of a schedule, here are some guidelines for when to clean the Air Scribe you are using
To field strip the PaleoTools scribe units you'll need: a pair of pliers, some small containers (for keeping all the parts from rolling on the ground), a selection of lint free rags, pneumatic tool oil as well as warm, soapy water. ALWAYS MAKE SURE YOU ARE DISCONNECTED FROM THE AIR HOSE BEFORE PROCEEDING |
