Just bought a shindaiwa 488. Decided to upgrade my Solo 636 which has been the best saw i have had. Apparently the guy lost the spring and spacer on the 488 chain brake. No idea what he was up to. Also won't start. Bought sight unseen, just a pic. Looks clean so decided to take the plunge at AU$200. If i get stuck does anyone have any bits for these? Postage would be ok to Aus. Is there schematics on how these saws are assembled. I am not a saw tech so will struggle to fix.
