Why does the engine spin fast but doesn't start?


Hi Kenny:
Old mechanic's philosophy; If you have fuel, and you have spark, it should run. Some more info would help. Did it run before? What happened immediately before it stopped running?
What is it? Give us some hints and we'll help you get mobile. Cheerfuls.

Sander doesn't spin


YOUR BALLBEARING where the disk is on mounted is the right bearing that have the problem for shure it is full of dust or completely dry it will not turn anymore SIMPLY TO CONTROL IF YOU MOVE YOUR DISK NOW ON YOUR MACHINE YOUR ARMATURE TURNS DIRECTLY WITH THE DISK thats not good the armature must stand still , replace the ballbearing or remove it and open it with a very little sharp screwdriver on the both sides solvent it out try to turn the bearing carefully until its turns without problems dry it or blow it out with a compressor and if its dry lubricate with ballbearing grease close it again and mount it again

My Model # 362 Belt sander keeps breaking belts after just a few minutes of continued use. Why?


This is usually indicative of someone pushing down on the sander too hard while sanding. The motor in this sander is strong enough to pull the belt around even with too much pressure on the sander. This causes excessive heat to build in the sanding belt and sander shoe which causes the belt to break down prematurly. It's also very hard on the sander's bearings and motor. Use an appropriate sandpaper grit that will do the job without excessive pressure on the worksurface. This will make your sanding belts and sander work longer and cooler.

Sander seems to struggle, doesn't run as fast as it used to. Air supply hasn't changed. Also, where can you buy parts if necessary?


I am not sure of a parts source, but you should consider putting some air tool oil and try to lubricate the air motor. It might be the problem ...a few drops in the air connection

Spin cycle doesn't spin but the motor runs


Hello there.

You most likely have a problem with the motor coupling. (please look that up).
You have a direct-drive system, meaning it does not use a belt but rather what's called a "motor coupling".

I probably replace 5 a week because these little guys break because of 2 reasons
that i've found.

1) The break mechanism is too dry and causing the basket to stop at a holt,
which puts a lot of strain on the coupler.
2) They break because of over-loading.
Good luck to you. The repair is kind of hard to do on your own for the first time,
so I would call an authorized technician. It will run you anywhere between $90 to $120
at most, including parts.

Best of luck!

Motor & pulley


It would take 6" pully w/ a 2.25" which would not fit on that machine, no room for the 6". Replace with the same RPM motor is the proper way, unless you simply want a slower speed sander, duh! You cannot change the motor rpm without a defenant power issue, if you change the rpm your sander will power out, sorry?
