It stopped working suddenly while I was vacuuming/mulching and will not start. I had turned it off to put an new leaf bag and when I tried turning it on nothing happened. I checked the cord and the outlet and both worked fine.

Might have a clog in there somewhere

bagging blades would work better together with any bagging system

First thing I would check are the motor brushes.

Undo the spring loaded cover on the very bottom of the machine, insert the vacuum tube for mulching in there and then attatch the catch bag for the mulched material to the outlet where the tube for the blower was...simple as that.

the shear pin has broke on the drive shaft put a new one in.

* CFM (cubic feet per minute) is the measure of vacuuming power. Ratings fall in the 350 to 600 CFM range. * MPH (miles per hour) measures blowing. Leaf blowers perform at levels from 125 - 210 mph. * Decibels (dB) is the noise rating. * Reduction ratio on mulching blower/vacuums calculates how many units of leaves the mulcher can produce. A 10:1 ratio means that 10 bags of leaves can be reduced to 1 bag of mulch. * Speed settings allow better control when blowing or vacuuming. * Attachments, such as extension tubes for cleaning gutters, are available separately.

* Blowers perform the single, simple function of blowing material. * Blower/vacuum combinations combine the blower function with a vacuum feature. Leaves or debris can be directed into an attached bag, which makes this type of unit great for vacuuming leaves from shrubs. An additional mulching feature is available on some leaf blower/vacuums. Mulched lawn debris can be used in compost piles or bagged for disposal. Most convert easily from blowing to vacuuming mode.

The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.

Your problem is probably a bad male cord end or the there is a problem with the cord winder. It might need a spacer.
