    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.

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

What kind of oil do i put in my skill saw 77

This saw requires Skil's heavy-duty, worm-drive oil, part number 80111. If you can find a local vendor that has some great otherwise, type 'skil 8011' in your search engine and shop around for an 8oz tube, they can run from $5 to $10 plus shipping.

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.)

For the Skil 77 worm drive circular saws what type of oil is required?

Use 90 weight gear/differential oil but if you use it outside in the cold weather it's too thick, use 40 weight oil then and switch to the 90 weight in the summer.

Need to know the type of oil that the skilsaw 7 1/4'' mag 77 use

skil recommends using their lube 80111 for an 8 oz tube or 80112 for a pint. however any good quality worm drive lube will work. Don't use a gear lube because the worm drive has additives for anti foaming and gear wear added. Let me know if you need more help
