I have a RedMax BCZ2600S trimmer - bought it in November, but started using it in March. I know that it is under warranty, but my dealer is a good 45 minutes away and wanted to see if there is anything that I could do to fix it before going in. I used to have no problem starting it up. Now it will "turn over" briefly (about 1-2 seconds) and then die. I am doing nothing differently to it. At a job the other day it fell off the trailer (about a 3 1/2 foot drop), but I see nothing loose or jarred upon inspection. Does anyone have any ideas on what it might be? Let me know. Thanks.
