    On some worm drive saws there is a fill line on the side. If you give me the model number i will research and see what I can find for you.

Haven't heard anything so I checked the Milwaukee worm drive saw and they recomment about 1/2 oz. Make sure you use an oil for a worm drive that is not foaming. Hope this helps. Also when checking oir level have the shoe set for max depth and on a flat surface remove the oil plug, when filling tip the saw on its side and fill, turn back over and allow excess oil to run out if overfilled.

If it's a Skil 77 that Craftsman is using it's maked right below the 1/2 inch fill cap on the right hand side of the saw. It's basically just below the bottom of the fill cap.

Im trying to figure out how to adjust the bevel on my new skilsaw 7 1/4 worm drive. I adjust the lever and I'm trying to turn the shoe of the saw and it won't turn. Can somebody please help?

New saw = tight pivot points where the saw meets the shoe. You have one in the front and one in the rear. As long as you are sure that the bevel adjustment lever has loosened its grip on the quadrant. You can spray the pivot points with some wd-40 or even attempt to muscle the shoe to get the pivot points broke lose. Just not so much that you separate the shoe from the saw.
If you still cannot get it I would return it for another one.

What type of oil does the saw require and how much?

Your Skil tool has been properly lubricated and
is ready to use. However it is recommended
that the gears be relubricated only with Skil
lubricants: No. 80111 (8 oz. tube), No. 80112
(pint) or No. 80113 (1/2 gal. can).
Always check the
oil level before
using the saw. To
check and add oil:
Remove plug from
power source and
place the saw's foot on a horizontal surface.
Remove oil plug using the same wrench used
to remove the saw blade. The oil level should
never be below bottom threads in the housing.
When adding oil, fill until oil starts to run out of
oil hole at arrow on housing and replace oil

part #80111 and is available from

How do I replace the spring on the retractable blade guard on a model 77 worm drive skilsaw?

Bearings maybe......I'd also check the armature fan and see if it came loose. Either way it doesn't sound cheap!

Use Skil worm drive oil #80111 ($5-$6.00) at Home depot, or Bosch WD7LUB 2.3 FL. OZ. (I bought for $3.50 at Bosch service center.)
