I have a Skilsaw wormdrive Mag 77 circular and the case on it says Oil is low what oil is best to use?

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

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.)

Hi MJ,

Either is fine.

The concern is not mixing them.

It should be one or the other, not both.

Best regards,

Mike

I recommend you call 800-346-4103 and press 1 on the main menu.

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

Yes I do Know where, here you go !

You have large plastic screw on the saw, remove it and fill the oil to bottom of threads and that should be it.

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.

I have a Skilsaw model 77 type 16. I have the original owners manual and would be willing to fax you a copy.
The manual only lists a part number for the gear oil, it is No. 249. This is for a 5-3/8 oz tube of gear oil. I checked with my local hardware store which services this saw and they called a factory rep. They told the hardware store with shipping and handling it would cost about $17 for the oil! However they also said that a 90 weight gear oil is close enough to solve the problem.
Hope this helps.
