I’ve had my Excalibur for a couple years now. I had to replace the upper and lower arms once already. I bought one that was the display/trial saw. How often should I take it apart and lube the upper and lower bearings, sleeves etc. it’s really just like the Dewalt as far as doing this? What kind of lube were people using? I’ve watched the video’s on the dewalt before also. I’m having no problems I’m just curious what others have done with it. Thanks.
