Anyone got a spare arbor spanner for a Kity 419?

[Richard D]

A good suggestion - but although the TS-200 looks a lot more like the insides of my 419 than that shown in the current 419 manual, the method to change the blade (and the spanner required) is still different.

Is the arbor bolt a clockwise or counterclockwise thread? I might be able to get the blade off by holding it with a welding glove (instead of using the special wrench) and using a standard 13mm spanner on the nut, but it doesn't want to shift whichever way I turn it, and I don't want to get too heavy with it until I know which way it should go. At the very least I think it's going to require thumping with a hammer, because turning it by hand or even light taps aren't achieving anything.

So, the nut on the bottom picture - to loosen it, do I turn it CCW (which would work for most standard bolts) or CW (if it's a left-handed thread)?

I think I'm driving NMA mad, by the way. It seems that nobody ever thought that these spanners could get lost, so don't seem to stock spares; plus the fact that the spec changed at some point means that Kity's new parent company have no idea how to help either.

I'm fast coming to the conclusion that I've wasted over 300 notes on this. Next time I'll buy brand new, and bugger the cost.

At last!

I'm still going to need the special wrench for future blade changes, but at least I've manged to get the current blade off.

It turns out that it's a standard CW thread. Blimey, I spent the morning taking the saw apart, hitting various bits with hammers, used lashings of WD40, but in the end it was a big impact driver that got the nut off.

it doesnt sound like the previous owners of yours gave it the same tlc that mine had from ed.

while you've got the blade off , now would be a good time to measure the jaws needed on an arbour spanner - then you can make one up from sheet steel, or even from ply.

I think I'm going to make do with a welding glove for blade changes, and hope that "would not" gets a few cut! The blade that's on there now (a hardwood crosscut blade) is likely to be the one that sees the most use for the time being.

Thats exactly the same fitting as my Bestcombi 2000 but rustier which uses a lot of the same saw parts so the 46mm AF spanner will do the job.

If you have still got it stripped down check the bolt that holds the plastic multigroove pully to the motor they have a habit of comming loose and the key that stops it rotating eats away at teh keyway in the shaft. Also if the belt tension is too loose it will take longer than the safe 10 seconds for teh blade to come to a halt.

I never did manage to find a 46mm AF spanner. Dad bodged something together out of a bit of scrap metal that served for most of the last ten years*, but it’s given up the ghost now so I’ll have to make something halfway decent out of some mild steel. Project for next week, I think.

* my hobbies go through phases. Ten year ago it was woodwork for a year or two, then the bike for a bit, then a year rehabbing after a bad bike accident, then the bike for a few more years. But as I'm working from home (I usually commute by bike), the cycling club's effectively been shut down by the various COVID restrictions, my bike is currently in bits and the weather's rubbish, I’ve got the woodwork machines out again.
Having a blast with it all too. This weekend's project is a new mobile base for the Kity419 - I bought it bolted to some sort of homemade stand consisting mostly of scrap iron, but it's heavy, not very mobile and has a very narrow "footprint".
