Congratulations on your fine purchase, using Echo powerblend, with 93 octane (no gasahol allowed) mixed 50:1 will yield maximum power and logevity. The powerblend oil has the highest rating possible for 2 stroke oils, using the japanese (JASO) requirments, which are more stringent than the american standard ISO requirements.
Standard starting practice is to purge 5 times, flip to cold start, pull once or until it burbles, then flip choke off, and pull. should fire. Now allow it to idle for 30 seconds, and it should go to full throttle immediatly. This allows the piston, and cylinder to come up to temp slowly at the same rate.
But isnt it nice not smelling like a small engine shop, back not sure from wielding a heavy powerhead, arms not sore for hours afterwards from the massive vibrations, ears not ringing from the loud muffler..and lastly...knowing that when you park it for the week, you wont come out to an empty tank and a puddle of oil residue.
Only real items that need replacing in the first few years are the rubber tank grommet where the 3 lines go in...that's about it. Check the air filter every so often, and if you get a hankering to do the annual service on your own...here is what you need.
Fuel filter
Echo-Lube
5/32" Allen wrench
5/16" socket
1/2" socket
Ratchet
CJ8 Champion plug
----Replace the plug.
Use the 1/2" socket to remove the plug on the side of the trimmer head, and use the echo lube to shoot in a couple squirts, ans recap.
Use the 5/16" wrench to loosen the 2 bolts that hold the power head to the shaft. Use the allen to loosen the groudn wire from just in front of the air filter, loosen the throttle cable by hand, and pop it out, this requires no tools. Now unhook the wire at the quick disconnect. Now slide off the power head. Reach in and pull out the flexible cable, and put a little echo lube on it as you slide it back in, now turn it a little so it seats into the trimmer head gear box. SLide the power head back on, twisting it so the clutch drum engages the square flex cable. Tighten the 2 nuts, putthe groudn wire back on, and hook up the 1 wire. Then slide the throttle cable back into the hole on the carb, and pop it into the hold on the throttle lever.
Check the air filter, probably not that dirty.
That's it, a total service, and it takes about 5 minutes to do in real life, honestly.
The gear box will remain quiet, no chatter from the flex cable, fresh plug, new fuel filter...keeps it ready to go, and it only needs a few minutes attention 1 time a year, hard to beat that! Echo has made it a snap to service these things, really.
I cant take 1 Ryobi apart to get to the flex cable in the time it takes to fully service an SRM echo.
The serviceable gearbox is great, and the echo-lube it top notch, and one tube will last you a lifetime. As much as we service and repair these things...we get a season from a tube.
