What happens here

The first step in preparing the Graco 695 airless sprayer is to lubricate the pump's piston and packings. Locate the lubrication port, which is on the front of the sprayer and might be covered by a protective cover. The presenter mentions that this cover is often left off in practice. Once the port is accessible, apply "packing saver" fluid, such as Spray Squirt Packing Lube, directly onto the piston. Continue applying the lubricant until the reservoir fills up and the fluid begins to spill over the top. This ensures that the piston and packings are thoroughly lubricated, which is crucial for preventing premature wear and extending the lifespan of the sprayer. This maintenance is recommended every two to three uses of the sprayer.

Goal: Prevent premature wear of pump piston and packings

now on a home and prior to starting the paint um and using the airless about every two to three times we use it we put some packing lube and packing saver inside the packings and on this model right here to actually get the lubrication it's on the front right here to show a close up to this area and we're going to take our packing sa and I've got the the uh protecting cover on it released right here there's uh screws that actually hold it on and I actually never actually keep it on it hangs right here always and you're going to just want to take your packing saber and you just start you put it up against the piston on the pump right here and you just start letting it run down the piston and you'll eventually see when it fills up over the top and I'm going to keep running my packing saver down in there and it's very important this is what keeps the piston and the packings lubricated so they don't wear out prematurely so I'm going to keep releasing some packing saber in there and once it begins to spill over barely I keep running it in in there it's probably about full now so now I'm done putting in the packing Loop
