I just purchased a LEHR ST025DS 25cc Propane Powered 4-Stroke Detachable Straight-Shaft Trimmer. This model can take various attachments, including a pole-trimmer saw.
Now, I know that aside from lighter weight, one of the reasons that chainsaws use two stroke engines, is because they can be run at all angles w/o worries of starving the engine for lubrication. What about 4 cycle engines in hand-held equipment such as this? I'm I going to ruin the engine in this trimmer if I put a pole-saw on it (which requires it to run upside down)?
Thanks,
Jay
