Hello, I have an old sears 14" electric chainsaw

The manufacturer no longer makes this part, and there's no substitute part.
If you choose to purchase a new product, that is up to you. The original switch appears to be made by EATON and it appears to be also used in some routers. Best of luck.

I'm looking at an owners manual for Michaela's chainsaw. We owned it back in the 60s. It's in really good condition, the manual not the saw. It was the worst saw we ever owned.

First loosten that 1/2 bolt on the bar--the lookat the bar when it goes into the housing you will see the adjustment screw.Tighten the chain by turning the screw when you get it to where you want it then tighten the 1/2 inch bolt

if such problem happened when you didn't touch the throttle, then open the filter cover and take out the filter you may see the carburettor and then pull the choke, you may find the issue

Look for a manual overload reset botton on the motor.

www.erplacementparts.com they have almost eveything. breakdown diagrams too.

The manual is available from Manage My Life (the Sears support site). Direct link is: http://www.managemylife.com/mmh/owner_manuals/16717/CRAFTSMAN-Saw-Table-L0805384?brand_name_search=113-298151 . If the direct link doesn't work, start here, http://www.managemylife.com/mmh/owner_manuals , and enter your table saw model number.

I hope this helps.

There are 3 versions of the 7" grinder model 4074. Sears Parts Direct has the manual for sale http://www.searspartsdirect.com/partsdirect/part-number/BLACK-DECKER-Parts/Grinder-Parts/741333-00/0009/900/Model-4074/1228/0721050?keySuffixId=NA&productTypeId=x&searchModelNumber=4074&subCompDesc=Unit%20parts&brandDesc=BLACK&DECKER&modelDesc=7 .

Black and Decker has pdf versions of the manuals for many of their products are here: http://www.blackanddecker.com/manuals.aspx . However, check the model number on the grinder. 4074 doesn't come up as a valid model. The usual model numbers start with alphabetic characters to indicate the type of tool. The site lists where to look for model numbers.

I hope this helps.

The best way I have found is to remove the sparkplug and rotate crank until the cylinder is down about an inch. Jam quiet a bit of shop cloth down in the plug hole then rotate the shaft until the cloth stops upward movement of the cylinder. Now you should be able to get the nut off. You can also remove the nut with a air impact hammer as the impact action will loosen the nut.
