Owners manual Black and Decker Radial Arm Saw Model 7770 Type B. Posted by ericmark764 on Jun 23, 2011. Want Answer 0. Clicking this will make more experts see the question and we will remind you when it gets answered. The model number is 7780 and it was made by Black and Decker. The manual is here.
I went to pickup a 10' Dewalt 770 Deluxe Powershop radial arm saw that I won in an online auction. The saw is in rather good condition for an old tool. It took us half a hour to finally learn how to move the yoke. (The seller is selling it for a very old owner, who is said to have owned it since it was new.) It turned out that one needs more than to loosen the lever, but the lever has to push on a bell to disengage a certain pin that fixes the yoke. But we still have not been able to loosen and turn the bevel of the saw, to have the arbor pointing against the table. It moves a little and is not frozen. There is something, may be a pin, that fixes the saw's bevel angle.
The terse printed description on the saw (the arm) says 'pull, and turn the saw.' The 'pull' is mysterious. What does it mean by 'pull' and then turn the saw? Does any one here own such a saw, Dewalt 770 Deluxe Powershop RAS 10', and can shed some light on how the bevel is moved? There does not seem to be anything broken. No sign of breakage.

Looks like a reasonable tool. We got the bevel angle. One pulls a pin (about 3/8' diameter) right were the bevel dial is. We had to use a pair of pliers. The Yoke is rotated as said, with the lever pulled to push on the 'bell'. A small disappointment is that it is only 11 amp at 120v. I suppose a 11 amp induction motor direct drive is still respectable power.
Next I want to know how to attach a drill chuck to the back spindle of the saw, for horizontal drilling and boring. I think I need a fine threaded 3/8' rod, a couple of inches long to attach a chuck. If you know what the thread type of the back spindle is for the attachment of a chuck, please let me know. It is a DeWalt 770 10' powershop RAS. Thank you all again.
