Dietz-Power wheelchairs

[Burgerman]

I found a way to fix those stupid modern "swing aways" things. The ones that look like the one below.
They are way too loose. If you pull it sideways too hard as you are aiming for a gap it at speed moves inwards. Very scary as you attempt to regain control. I took it apart, its full of springs, toothed belt, pulleys and no obvious way to tighten it up or modify.
In addition its got detents that click loosely into place STRAIGHT AHEAD and 45 and 90 degrees.

The straight ahead one is too far to the right and lible to get the controller wiped out by a door frame, and its uncomfortable. The 45 degree inbord is way too inboard. I need a 20 degree to the left position...

Anyway if you order 3 or 4 rubber washers, 30mm OD, 12mm ID from eBay and place them between the swing away thing, and the underside of the arm, and pull the thing up tightly to crush the washers and then tighten the allen screw it firms things up. The swing away no longer wobbles, and it stays wherever you put it securely unless you REALLY want to move it. This wont bother you though.

Dietz swing away is firm already and has no wobble in normal use.

[Burgerman]

Well the sunrise and the permobil ones are not! Its more the fact that they are too easy to move position left/right rather than wobble that annoys me. I almost ran into a parked car while aiming for a gap between lamp post and car when I hit a bump and my hand pressure moved it inboard unexpectedly.

I never saw a Dietz one. It looks similar? It wont bother steve anyway as he uses feet... God knows how!

Dont ever take one apart. Putting it back together made me swear a lot.

[steves1977uk]

Yes BM, I went for RWD and have paid a deposit to rover. So should be getting it soon!

Steve

Well you've not paid it to me exactly.

I know that!

Yeah I wouldn't entertain opening a sunrise one unless I had a spare to replace it with

DIETZ are easy to open and put back together, as long as the springs don't fly!!!

Duke1,

are you still looking for a dealer to see our chairs at?

[ex-Gooserider]

I'd love to see one, any dealers in the US???

Not just yet I'm afraid. Most parts of Europe but not got to North America.

Nice 1 Steve Sound a good chair

[steves1977uk]

Pics and review will be posted after a few tweaks. At the moment it's a struggle to get on/off the toilet, even in the lowest position. So it looks like I may have to forgo the seat lift or just keep it for outdoor use only.

The seat sits about two inches higher than my old chair which is the right height for most things. Apart from that I'm well pleased with the Dietz Sango chair.

Many thanks to Rover for spending time trying to set it up as close as possible and letting me reprogram it to my settings that suit me.

Seat height can be dropped if necessary.

[steves1977uk]

Good to know rover. I'll also need a longer seat as I keep feeling as though I'm gonna slip off the edge. The front strap also needs to be longer.

Thanks for your help.

no problem, just small tweaks then.

[Burgerman]

On most chairs the seat lift modules are pretty similar. And about 2 inches thick. So on most chair it means that with group 24 batts, the seat does sit 2 inches (or at least 1 inch higher). And on some cairs that can be lowered but at the cost of battery size being group 34 as they are the same but an inch shorter in height. And lower capacity. And seat depth, dump, and width is usually just a relatively quick spannering job!

I am presuming the Dietz chair is similar?

Yes pretty much.

Steve's is set on the highest of 4 positions to help footplates clear the 10inch castors. Will be able to drop the static height down no problem and tweak footplate position if it results in clashing. No need to remove lift module.

Just nuts and bolts to tweak. Always going to be required when going from a 20yo plus chair to something new.

[Burgerman]

Maybe those 8 inch x 3 inch wide "smooth" tyres I used on that q700r will give him a couple of inches extra.

Certainly, up to Steve on that one mind.

[Burgerman]

These?

[rover220]

These?

My bad, I thought you meant the smooth castors then noticed you'd put 3.00-8.

You raised the footplates up, so lowering the seat shouldn't be an issue? My current daily chair I've had since 1989, the bottom half of the frame have been replace but the top half is still the original chrome frame which hasn't flaked or rusted which is quite something!

Yes I can use the height we save on that to drop the static seat height.

[Burgerman]

The smooth caster tyres are 8x 3.00 - 4 and thats what I meant. Those are 2 inches smaller diameter giving the ability to move the footplate back.

Thats 8 diameter, 3 wide, fits a 4 inch caster rim (or: 8x 3.00 - 4) https://www.terraintyres.co.uk/turf-law ... mooth.html
The 3.00 x 8 are the rear tyres. Although mine are 120/70-8.

My bad, I thought you meant the smooth castors then noticed you'd put 3.00-8.

Kenda 8x3.00 - 4 caster tyres. 2 inches more footrest clearance.

[steves1977uk]

Those tyres look ok BM, but I'm guessing I'd need the backend lowered too?

There's a spacer in the rear that would need removing. Let's try dropping seat height first

[Burgerman]

Its fine even without dropping the rear with a removed spacer. Its not a huge difference. The tyre may be 2 inches smaller but the front sits 1 inch lower. You can usually adjust the suspension to have a little less preload (height) at the rear if it really needs it. Those tyres - esp the carlisle branded ones are very tough. Probably a good candidate for not getting a puncture. But will give a harsher ride that the 10 inch ones you have.

Take a look at the pic of the q700r above. That has bigger rear tyres AND smaller front ones. Its not had any suspension changes or spacers moved or anything. Yes it leans forwards a fraction (maybe 2 degrees?) like a dragster! Its not critical at all. Works just fine.

Ok, let's try that first then rover. Told my Mum to ignore the green light on the charger and leave it on for 24hrs.

BM, would it be better to use my Shirley PSU in 3-stage charge mode to charge it better? I'd have to get someone to make me a XLR cable since my Brother is having an eye op soon.

Steve

[Burgerman]

Yes if the fan noise doesent bother you.

For GEL
Set it to 3 stage.
Set to 12A.
Set to 28.2v
Set it to 27.0V FLOAT. Set the point that it goes to float to 0.3A. If it does that OK, reduce to 0.2A.

For AGM
Set to 3 stage.
Set to 12A.
Set to 28.8v
Set it to float at 27.2v
Set the point that it goes to float to 0.3A. If it does that OK, reduce to 0.2A. If it manages to do 0.2, try 0.1A. If its still not on float inside 8 hours at CV then revert back to 0.2 or 0.3A. You are aiming for 8 hours CV ideally. Or 10 on GEL.

Be aware that if the XLR is plugged it you have direct battery connection to the 4mm connectors! If they touch you will blow up the wiring on the chair or on the pod. So use C terminals and screw them to the shirley charger. Or use anderson connectors on the chair and on the charger if possible. Even if only on the chair end it means you wont damage the chair if it gets shorted out. It also means you can up the charge amps from 12A to 25 or 30A. And so top up fast during the day.

But you just know you want to add 200Ah of LiFePO4 really...

Steve , would you please get me a user/service manual of this chair ?

It need to go lithium .
