I picked up a gently used Olympyk 942 saw for use around my property; primarily limbing and samller work. The saw runs great and is mechanically solid. The only issue I have is with the auto oiler. The volume of oil is this thing is pumping is excessive. Run the RPM's up and the lube drips from the front the saw. I have no operators manual to assisit in a DIY takedown. Although I could take it in for repair. Is this over lube issue common with auto oilers? Thanks in advance. JLP
