Size for size and component value identical on replacement. Fit the correct part.

Considering how potentially dangerous grinding machines and wheels are and how much safety legislation exists about their maintenance, adjustment and use, a great deal of printed matter exists about these things and the wide range and selection of wheel material. You should have no bother finding useful information, fortunately bench grinders are extremely similar to each other...

A wire wheel is bought from the same sort of supplier as you would buy a grinding wheel. The dimensions of the wire wheel should be similar to the grinding wheel it replaces, though the centre hole is usually larger and should be fitted and mounted with the correct size plastic bushes and steel retaining washers. The guard and the tool rest should not be used with a wire wheel for safety and of course there should be a hook nearby to hang a pair of safety goggles... Bear in mind, in a commercial environment, local legislation could exist that means only a suitably qualified and registered person is allowed to maintain/adjust a grinder as in the UK and Europe.

Mmmm... that's a little more complicated. If you have a continuity / resistance meter, we can noodle it out, though. First, are the two white wires the ONLY wires coming from the motor? I suspect they are - that's not in conformance with any accepted color code, but it'll work. For the rest of this, I'll assume that the two white wires are the only ones from the motor. You'll need to meter the switch itself, with no wires connected to it. In the OFF position, you shouldn't find continuity between any of the four switch contacts. In the ON position, you should find continuity between two pairs of contacts. The black wire from the power cord should go to ONE of the two switch contacts in a pair that have continuity with the switch turned ON. One (either) of the white wires from the motor should go to the other switch contact IN THAT PAIR. That leaves you with one more pair that has continuity with the switch turned ON. The white wire from the power cord goes to one of those, and the second white wire from the motor goes to the other one. When you have it all wired up, plug it in & turn it on. If it's not right, it should immediately pop your circuit breaker. If it IS right, it should run fine. If it pops your circuit breaker, open it back up and swap one wire from the power cord and one wire from the motor.

Usually, 4 wires are multi-directional neutral and earth are usually colours the other 2 are both live and would need to go through a switch. you can of course put the other live in a cover and just use one live wired as usual into a plug. Make sure the spare wire is well protected ie in a jb with plenty of tape around it

I didn't find a manual when I searched. A similar model for sale shows a vender site, where you might ask the question of whether a manual could be provided to you.

I have used a double-ended bench grinder for years with only a single wire brush, without problems.

Depends what parts are needed. Spare parts for something that goes wrong so rarely can be difficult especially if the machine is imported. Some parts will be fairly universal and so fairly easy to obtain - nuts, flanges, abrasive wheels, bearings, capacitor (if fitted) and possibly even the switch and tool rests.

Yes I do. Do not over tighten the H and L needles you will ruin the needle seats (clockwise closes the needle jet, counter clockwise opens the needle jet) There is no air mixture needle on a chainsaw carb (2 cycle engine) all are gas mixture needles H - high speed operation, L - low speed operation. [The saw carburetor operates like a 4 barrel carb on a 350 chevy, runs on 2 but kicks in all 4 when you hammer it.] Turn the H needle to 1(one) full turn open (counter clockwise). Turn the L needle to 1 1/4 (one and one quarter) turn open (counter clockwise). NEVER EVER close the H needle to less than 3/4 open or the L needle to less than 1 turn open. If you do you will burn the saw up from lack of oil lubrication. [I have several Jonsereds saws a 52E, 451EV, 49SP, 520SP, 621 race saw, 630, 70E, 70E race saw, 80E and last but not least a 90E. I worked many years for the importer and distributor of Jonsereds as a Territorial Rep. All my saws run like a top. My newest saw is a 1984. I chainsaw carve and cut firewood with all of them year round. In short I like-em, they're the best.] I find that all my saws run the best and strongest with the carb set at around 7/8 turn open on the H needle and just above 1 turn open on the L needle. The idle screw I set last after the saw responds correctly to the carb settings. I quick throttle the saw to make sure the saw picks up RPM and doesn't fade out, put in a log to make sure it maintain tourque under load and not bogg down (tweak the H & L if needed, remembering the 7/8 - 1 1/4 rule I adjust the idle screw to where the saw sound smooth and un-labored at idle. I never let it idle to where the chain moves when it idles. For safety reasons. Hope this helps. EdN
