Cleaning A Graco Contractor II Gun. Repair an Airless Spray Gun.

What happens here

Next, unscrew the handle section of the gun. There's a filter inside this section that needs to be pulled out and placed into the lacquer thinner. On the packing section, there are three O-rings that need to be carefully removed. Use the small flathead screwdriver to gently pry off these O-rings without stretching or damaging them. If the O-rings are damaged, they may need to be replaced. Place all removed O-rings into the lacquer thinner for soaking.

Goal: Remove the handle, filter, and all O-rings from the gun body.
