Can't take off front off porter cable tiger 747 (rubber boot

use a pair of tweezer to pull it out or a magnit

blow it out and spin the motor by hand you may have saw dust blocking the brushes. If that's not it check the brushes to see if they have life left in them. If not that check the cord for an open with a volt ohme meter.
Hope that helps!

Not much chance I can see of getting the **** thing out of my saw either.

Mebbie I gotta try something else,

use sewing machine oil, or 3 in 1 oil, you could use WD40 as well. but not motor oil

Its hot pressed onto the shaft its made not to come apart because if it did in use it would not be good. I use sawalls all of the time and fine if the blade snaps low you can get them out with a strong magnet if you hold it up side down and turn the collar shake it around mabey spray some WD40 in side first it may take a little doing but it beats takeing that change collar a part.

Hi rq,

Look at the base of the blade, there is either a half twist quick disconnect or an allen screw.

Safety first: Unplug the saw.

If its the allen screw it will be located to one side of the blade. Just loosen it , pull the blade out.

The half twist ring doesa what its name implies. Twist it as far as you can (holding the saw with the bladed to the ground allows it to drop out) to free the blade.

At the base of the blade where it attaches in the saw you will see a round in shape with ridges fixture. Turn it so the slot is in line with the blade. Then you will be able to remove the blade. If the fixture does not turn, move the blade up and down while you turn the fixture.

There is a ball lock in it and you have to twist the ball lock but if the ball lock is frozen generally WD40 will help unfreeze it and work it until the ball is free and should work just fine.

This is a jigsaw miscatagorized as a chainsaw. Do you have a blade big enough to drop 24" tree? We don't answer jig saw questions in the chainsaw section.
