« Part 10: Cabinet idea's for my RAS! Part 11 of 1950's DeWalt MMB 23 RAS series Part 12: Building a RAS table? »

I am wondering do my DeWalt RAS roller bearings need adjusting? Because my RAS wont’s to roll on it’s own to the front of the saw, I am not using it till I figure how to fix that.

Radial arm saws are not supposed to roll on their own to the front due to three reasons
1. If you are lining up a cut and it accidentally rolls forward it could kick the board up into you and pull your hand into the blade.
2. It would be very annoying and unsafe if the carriage crept during operation and if you weren’t careful you could wind up accidentally contacting the blade.
3. A drifting saw could accidentally catch and destroy the blade (believe me I seen this happen in high school shop class) and throw pieces of carbide and other metal at yo or around your shop.

OSHA and most radial arm saw Mfrs say that once the carriage is released by the operator the saw carriage must return to the rear on it’s own either through a auto return or the saw being shimmed up in the front to cause the drift backward.

P.S. I have the OSHA standards for general industry book where I backed up the info I just give you
BTW 921 pages and very boring

if i’m not mistaken
the bearings have a off center bolt
and turning them will tighten/loosen the bearings

you can also tilt the saw back some

put a door type spring to pull it back

have a weight on a roller at the back
that comes up when you pull the saw forwards
and takes it back
when released
