I wonder how long it takes to break in when it's doing 10000 rpm? I'm guessing a few minutes at the most?
2 Stroke trimmer engine break in
- Thread starter SilentType
- Start date
I've noticed that the new trimmers I've bought felt ua bit under powered for the first tank or two of gas.
The 2-stroke procedure for motorcycles I've read is very straight forward and much easier than 4-stroke engines.
They basically need 2-3 heat cycles (basically to sit the piston rings) before they can be operated normally:
1st heat cycle - moderate use for about 5 min., then shut down and let the engine cool down.
2nd heat cycle - moderate use for about 10 min., then shut down and let the engine cool down.
3rd heat cycle - moderate use for about 10-15 min., then shut down and let the engine cool down.
Then the engine is broken in and ready to be used at full throttle. Some people also use slightly more oil during those cycles and the first few tanks of gas too.
However, if the owner's manual doesn't mention anything about breaking in, those engine might be already broken in from the factory.
I also was never affected by poison oak and ivy until one year during summer (hot and humid - so I was wet from sweating) is was line trimming a heavy section that was full of it for a couple hours. Safety glasses should have been face shield. Must have got some leave debris on my face and ended up with my first poison oak rash. I did not use good practice of showering and changing clothes immediately after cutting since vacant property I was working was a couple hour drive from house. I had short sleeve shirt and only had rash on my face. I have not had any issues since but using better protection. Some suggest that our immunity to poison oak/ivy can change over time.Now that I've run it some it's probably time for a little WOTlol. I plan on putting on the brush blade kit this fall/winter and handling the overgrowth along the driveway.
I've never been allergic to poison oak until this spring, ended up getting it all over my arms and hands twice. Maybe clearing the brush in winter is the answer.
Winter or possible spraying in season is possibly better than using a line trimer/blade; although I do think if you cover up well (long sleeve shirt/pants, face shield, and hat and shower immediately after working in the ivy oak and laundering your clothes most will not have problems.
