Use the blade wrench to remove the arbor nut holding the blade in place. To loosen the nut, turn the wrench in the same direction as the blade cuts. Retract the saw’s upper blade guard and remove the old blade. Slip the new blade onto the saw’s arbor, making sure the saw teeth face in the direction of rotation.
Can you put a circular saw blade on backwards?
Yes – a circular saw blade can be accidentally mounted on the saw backwards – but it is a mistake you will only make one time because you will find out the instant you try to cut a piece of wood. It will not cut and you will be embarrassed at your mistake.
Why is my circular saw blade slipping?
The blades they’re making these days are thinner than the older blades and some of the older saws have to be shimmed in order to prevent blade slippage. A very thin kerf blade might spin, if the inner and outer nuts connect before clamping the blade.
