Use a round shaft screwdriver place between the blade teeth to prevent it from turning.

The blade does not tighten on the spindle and just spins freely. Even tightened down the center nut does not make a good connection to the blade.

There is a positioning "washer" that needs to be in place. If you don't line up the blade and position the washer it will not tighten. The blade will just spin around. Some even have a washer in front and in back. Be sure you have correct diameter of arbor that matches your blade too.

The plate that I tighten my blade against spins independently from the shaft from the motor where you tighten your locknut into. So even when the blades properly installed it doesn't spin.

the back washer may be just round and the front washer is made to fit on the fats of the shaft
at least one washer has to be fitted so that it has to turn with the shaft
now ensure that the nut to tighten up the blade is not bottoming out and being prevented from locking the blade between the two washers

How do you tighten chain

Thanks for contacting FixYa. I was just reviewing some of the old unsolved problems and wanted to make sure your question gets resolved.

Chain can be correctly tightened by loosening the axle nut so the axle floats. Then tighten the chain tensioning nuts on either side evenly so they tighten the chain. When the chain is properly tensioned you will have 3/8th - 1/2" of slack between the chain and the swing arm. Then re-torque the axle nuts and lubercate the chain. Should be ready to go.

The blade on my B&D sawcat spins even with nut tightened. cold it be the blade is worn, but i put a new blade on and it doesnt spin as freely but still spins

Hole in the blade is greater than spindle on the saw, you did not put bush washer/reducer in, or if that bit is correct, you are puting holding nut wrong way in.

Do not use saw till you rectify the problem, switch off the saw, remove power cord from socket.

1. raise saw table up for maximum cut
2. retract slide-in protector to maximum
3. remove nut from spindle, following by blade (and bush if used)
4. check internalholding washer if it is correctly inserted.
5. orient correctly internal washer (it have notch or notches and will go freely only one way - check if that is the case)
6. insert blade, with reducing bush if required
7. if external washer is used put it in
8. screw in the holding nut, hand tighten and check mobility of the blade, tighten up about 1/8 to 1/4 turn with spanner, this should be sufficient to hold blade in place without any slipage. If slipage is still present, you are doing something wrong, you need then to supply me with exact model and I will describe exact part look and order in which they must go in.
9. connect to electrical outlet
10. short switch on and off
11. check blade for wandering and slipage, if none then make test cut
12. use as usual if 11 is correct

Hope this will solve your problem :-)

How tighten a chain

well first get the bike up on a stand or set it on a milk crate. Loosen up main axle nuts you may need another wrench on the other side to back it up. loosen any small chain adjustment nuts. pull the chain as far back as it can go all the time looking a the chain sag..you want to keep about 5/8 to 1 inch play...lock just the axle nuts down snug...now spin the tire to see that all parts of the chain maintain this amount of sag. if its too tight in one area, you have a "stretched chain", and this will now be the focal point for tightening up the chain...this tighter part must have "some" slack in it...id say give it about 1/2 inch...now tighten up the chain adjustment nuts finger tight and look at your rear sprocket and make sure it lines up perfectly straight on with the counter shaft sprocket up front. Once this is aligned, tighten the smaller nuts snug, then proceed to torque down lightly maybe 10- 20 ftlbs. now spin the tire to check your slack in the chain did it move on you? Then you have to tighten or loosen the chain adjustment nuts a little more in or out till you get it right so it can move into the correct position. Once you got it right torque down on the main axle nuts 50-60ft lbs. Now tighten evenly each chain nut with the same ammount of turns to each....tighten the last nut down hard onto the first so they wont vibrate off. Now you should lube the chain..and your ready to go. after a while of hard riding recheck everything just to make sure shes secure! Can i get a very helpful on this. thanks!

How do i tighten the chain on my 2002 vfr800 vtech, it seems a bit loose and i can hear it dragging

Set the bike on its center stand, then loosen the rear axle by removing cotter pin from hex nut and loosening the nut. There are two adjustment bolts, with lock nuts - one on each side of the rear axle. They are easily work with from the rear of the bike. Loosen the lock nuts and turn the adjustment bolts clockwise. this will draw the rear axle (wheel) backwards - tightening the chain. Take care to turn each side the same amount, so the rear wheel remains straight. Usually the flex in the chain should be about a quarter inch. After adjusting, tighten lock nuts to hold position of rear axle and tighten the axle nut, replace cotter pin.

Please rate this answer. Thank you.
