This fellow rebuilt his Benjamin pump with a kit from Sun Optics and used Motor Oil to lubricate it PER THEIR INSTRUCTIONS.... On his first use after the rebuild, topping up his Marauder from 2400 psi when he got to 2800 the hose blew up, embedding shrapnel in his feet and burning and bruising them.... It also cracked the housing of the pump.... Yes, he was pumping barefoot.... IMO, pretty obviously a diesel type explosion.... but when he contacted Sun Optics they stuck by their recommendation to lube the pump with Motor Oil and told him there must have been "a spark".... Do we need to say it again?.... HPA is Dangerous.... HPA and Oil DON'T Mix.... Bob _________________ Dominion Marksman Silver Shield - 5890 x 6000 in 1976, and downhill ever since!

Poor guy.... Sun Optics may want good legal representation right about now... _________________   Posted: Mon Jun 13, 2011 9:53 pm sniper Silver Status Member Joined: 28 Nov 2008 Posts: 3752 Location: Star, Idaho I'd sue. _________________ I believe in gun control, If there's a gun around I want to be controlling it.......   Posted: Mon Jun 13, 2011 10:30 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6908 Location: "Out There" Myself and another gentleman had some "dealings" with the pump importer- "Sun Optics" awhile back- they gave out bad advice and obviously had no idea what they were talking about, lied about shipping spare parts, made commitments they had no intention of keeping... and here's the best part- this "Man of his word and great advice" (there seems to only be a couple people there who get near the phone- the technical genius and the owner), anyways, he was apparently an ex-employee of Compasseco (prior to PyramydAir buying them)- who knows what sort of advice he gave people on airguns! While I don't know how anyone can verify that they did, in fact, say to use engine oil in a multi-stage pump- if they did I think someone should call up their lawyer...   Posted: Mon Jun 13, 2011 11:00 pm rsterne Moderator Joined: 15 Jan 2008 Posts: 2998 Location: Coalmont, BC From the Sun Optics website.... http://www.sunopticsusa.com/handpump.html They mention using Motor Oil for a lube in several places....

I once had a phone confrontation with the resident "airgunsmith" of Compasseco. No offense to those in the south. It was clear to me I was dealing with an ignornant hillbilly only pushing product out the door. Yeah, springer bores need cleaning every 50 rounds with a patch soaked in rubbing alcohol. _________________ I believe in gun control, If there's a gun around I want to be controlling it.......   Posted: Mon Jun 13, 2011 11:26 pm AirGunEric Site Admin Joined: 20 Jan 2007 Posts: 6908 Location: "Out There" I am posting the content of that webpage for anyone thinking of taking them off to court sometime: http://www.airgunhome.com/images/SunOptics/SunOptics_handpump.html Last edited by AirGunEric on Mon Jun 13, 2011 11:31 pm; edited 1 time in total _________________ ` I'd say "I care."

No injuries this time, but it blew the main pump tube right off the base.... no pics yet.... Bob _________________ Dominion Marksman Silver Shield - 5890 x 6000 in 1976, and downhill ever since!

They now use the term "O-ring lube" without specifying what to use.... Bob _________________ Dominion Marksman Silver Shield - 5890 x 6000 in 1976, and downhill ever since!

Maybe the second guy threatened a lawsuit or something. _________________ ` I'd say "I care." But I'd be lying.
