hi cindilou50
check the oil filter from the oil tank,the oil line ,the worm gear and the oiler under the clutch.Clean the ways where the oil goes with compresed air.(after you fill out the oil tank)Also check the oil hose.

Did the chain come off while at speed? The chain catcher causes burrs to form on the drive links when occurs. Without the catcher the spinning sharp chain contacts your leg. Were you wearing chaps? We don't need no stinking PPE!!!
Use a flat file on the drive link flats to remove the burrs.
Chain Adjustment

1. Make sure the chain brake is off (gloves will protest your fingers).
2. If necessary, loosen the bar nuts that are clamping the clutch cover in place (or whatever holds the clutch cover and bar on). They don't need these really loose - finger tight will do.
3. Ease the tension adjustment until the chain is obviously loose.
4. Using one hand, hold the nose of the bar up.
5. While holding the nose up, adjust the tensioner so that the center of the chain just touches the underside of the bar, add a touch more.
6. Continue holding the nose of the bar up & tighten up the bar nuts / bolts / quick-release system. HTH

Any weekday between 1300 and 1600, stop by McNasties, buy 2 premium coffees (one black). Continue on to your friendly neighborhood Husky dealer (leave the saw in the car) and present him with the coffee. Discuss the problem you are having and ask for his help. It appears to be possible to replace the tool-less setup with the tried and true version. I estimate $20-30. Probably less than repair cost for your current arrangement.
Is not new and improved wonderful? We found a way to simplify manufacture, use fewer parts, and negatively impact how well our product performs... You pay more!

Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week.
I hope this was helpful.

This machine has a geared side adjust tensinor, i woud say the gear system may have striped, remove the clutch and drum, remove the allen screw securing the silver bar protector plate, the adjuster will now just lift away complete, check its function, replace if required, check the oiler is working, hold the saw over some cardboard, rev the engine and check to see if there is a good oil spray onto the card.

Put a lock washer on it to stop it from backing off.
