Hello, I am a beginner in engraving and recently acquired an (un)used Gravermeister with less than 100 hours use on it. It’s probably 35 years old (800-1200 SPM) and was stored in dry California climate so looks almost new (see picture). After talking with GRS, I purchased a new 915 handpiece that came with a new air hose. The handpiece tends to get very hot only after 30 minutes of use. I tuned the handpiece per instructions and running the Gravermeister around 1000 SPM. The oil level is little below the level mark. Is there a way to fix this overheating problem? Thanks in advance for your help and suggestions. I am enjoying learning engraving and the air assist is very helpful in reducing my learning curve.
