Hi
I got as a christmas present a very fine Petromax HK500 powerlamp and it is now working fine when I finally realized the quite complicated startup procedure and that it must be preheated very long before ignition!
But, I still have some problem with the pressure pump. The pump has an leather sleeve which I have oiled with a tiny sewing machine oil. But when I am pumping pressure in the ignition phase the pump very often fails and hits empty.
Could you please tell me if I can get a better functioning pump if I replace the leather sleeve with the O-ring attachement? Is this possible and where I can order such a sparepart? My Petromax was bought from Kaasuvalo in Helsinki but they dont have separate spareparts, only the set of Sealing Devices, but this set does not include O-ring attachement for the pump.
