What owners like and complain about

Echo CS-361P

  • Same 35.8cc pro engine as the CS-355T in a rear-handle layout that is safe to run from the ground
  • Owners consistently describe it as smooth and quick-revving with usable low-end torque
  • 8.4 lb powerhead keeps it genuinely compact for a rear-handle saw
  • Spring-assist start, tool-less air filter access and side-access tensioner
  • 5-year consumer warranty on an Echo pro-line saw
  • Documented weak point: the rubber cushion between the lower left handle and the case tears out and needs replacing
  • $389.99-$439.99 is expensive for 35.8cc — the CS-3510 cuts nearly as well for $90 less
  • 3/8 low-profile chain limits cutting speed against .325 saws of similar displacement
  • Capped at a 16-inch bar, so it will not take over firewood duty
  • Dealer-weighted distribution means no retail review aggregate to sanity-check

Echo CS-4510

  • Spring-assist starter noticeably reduces pull effort for a 45cc saw
  • Momentary stop switch springs back to ON, removing a classic no-start red herring
  • Tool-less air filter access and an automatic adjustable oiler for field maintenance
  • .325" chain on a 16- or 18-inch bar is a faster-cutting setup than the 3/8 low-profile homeowner saws
  • 5-year consumer warranty with Home Depot and Echo dealer support
  • Hard to justify against Echo's own CS-4920 — same 11.1 lb, 50.1cc instead of 45, 20-inch bar capable, for about $20 more
  • Seeps bar oil when stored with a full oil tank
  • Owners report stubborn cold starts, and several say it runs poorly on lower-octane pump gas
  • Thrown chains during break-in and a chain brake that is awkward to disengage when fitting a new chain
  • Capped at an 18-inch bar, so it is not a felling saw
