My 5 year old Echo CS 4400 had a chain brake malfunction with stressed spring metal
The new one arrived in the mail 6 days later than suggested in the order. The two holes for attaching the brake to the saw were drilled 3/32 too far apart and had to file plastic and metal to get it on. When I got into the woods to work, the orange plastic paddle had been redesigned and was too close to the handle by an inch or two. Now my gloved hand (winter in Maine) caused the brake paddle to constantly engage the brake and stop the saw. I tried to loosen the nut to change the paddle location but the nut is on a bolt with a round Philips head and the bolt turns with the nut. I hack sawed a kerf in the Philips to get a real screw-driver on it and eventually got it apart to find the paddle position can't be altered. Assign a bunch of desk-jockey engineers to a project and so long as it looks pretty it's done, don't matter it won't work at all. I can't send it back with my Alterations but it won't work proper anyway so time for a new $300 saw. A bargain considering an ambulance ride is nearly $ 1500. $2000 if they give an Aspirin for the pain. For $57 I'll lick my wounds and be fine. I'll write it off as a bad-date.
