Coleman UT400; Hisun HS400 model changes...

[cliffyk]

I acquired a Coleman UT400  just after Thanksgiving (2020) and find it to be quite different than most others seen on the web--the most visible difference is that the cylinder slants toward the rear placing the "hot spot" under the bed rather than under the seat (a significant improvement to my mind). THe curious prt of this is that neither Coleman nor  Hisun seem to acknowledge  this major design change. In fact the Owner's manual supplied with the vehicle appears tp haqve been written for a completely different unit--showing the ignition and light switches mounted in the dash (they are stalk mounted on the steering column on mine) and indicates that to change the spark plug requires removing the seat (the cylinder head and plug are under the bed on mine):

I wrote to Coleman and they sent me a what is supposed to be the most recent "UT400-5" manual which is still wrong about 90%+ of the vehicle. Neither the Coleman or Hisun websites are of any use as their content provides no photos and very little information about maintenance or the engine/drive train in general.

Is anyone aware of when these changes were made, or of any sites offering info re: this latest mode?  Currently I'm battling shift cable adjustment to find better and more consistent reverse gear selection.

Mine also differs in that the parking brake is a single caliper and disc mounted on the rear differential pinion shaft (this seems to be a "5 brake" configuration I have found reference to.

Overall it seems well designed and manufactured--the chassis welds are as nice as you could ask for and the castings and  machining are top notch.

Any information or suggestions as to where to look would be appreciated...

TIA

Kind of odd... usually manufacturers are better about updating stuff.

maybe someone at Hisun finally got it right with this one machine, lol

The owner's manual provided on Coleman's site does not even accurately reflect the machine shown in their video on the same site. In the video the vehicle clearly has a steering column mounted ignition switch--while their manual depicts a dash-mounted switch. Also the gauge cluster shown in thw video isw like that in the machine I have--the cluster described in the online manual is entirely unlike that in my vehicle--the manual provided online by Coleman  is wrong about most everything

gauges/controls from video heading Coleman's site:

gauges from on-line owner's manual:

Then there's the whole bit in the manual about using the choke to start a cold engine:

It's an EFI engine, no choke--I feel sorry for those owners that spend time looking for a choke...

Another anomaly;  In looking at parts lists for the Coleman and its cousins (the Massimo MSU400 and Bennche BH400) I ran across this reference to the engine oil cooler:

 

Note the "(2012 and older)" annotation re: the oil cooler-- My 2020 Coleman UT400 has the engine oil cooler...

I just picked up a 2020 Coleman UT 400.  Overall, seems like a nicely made machine.  But like CliffyK, the owner's manual is absolutely useless.  my engine is also reverse mounted, i like the instrument cluster, for the most part.  My issue is: in F gear it stalls as I try to accelerate.  I cant make it over 10 mph and 4K rpm.  Like it is running out of gas, or there is a vacuum lock.  I opened the hood and found there is an electronic speed limitor.   Was thinking of disconnecting it to see what would happen but thought I would check with you guys first.   I can get good RPMs in neutral and in R.   At slow speeds in the sticks, F seems to work fine.  Also, I cant the gas gauge to get an accurate reading; I can see gas in the filler tube.  Also, the coolant reservoir was empty.  Next, there are two big black tubes on either side of the crankcase not connected to anything.  Part of emissions control system?  Very odd.

Advice/comments???     Had polaris quads for years, very different

It will not go over 10 mph unless the driver's seat belt is buckled. Or the "safety" interlock defeated in some manner. Removing the limiter module does not work. You can buckle it behind your back but that's a bit uncomfortable. You'd think they would mention this in the manual--wouldn't you?

I 3D printed some tabs that mimic the seat belt male connector.to trick the foolish thing

It is 45 mm x 20 mm x 3 mm, just a clone of the seat belt connector. I have made these for my other vehicle's as well. I had open heart surgery a couple years ago and cannot wear a shoulder belt.

If you send me a SASE I can mail one to you--I  will send you a PM with my address.

The normal level of the coolant t reservoir is quite low in the tank--you have to peek in around the framework to see it. The black tubes are exhaust outlets for the generator and CVT air-cooling.

My gas gauge works fine, I have seen reviews on he Tractor Supply web site reporting it did not.

Unbelievable.   I have never heard of such a thing.  I will try it and keep you posted.  I would be interested in your defeat device.  I hope you have recovered from your surgery and are feeling well.     Mark

Big Brother is always watching out for us!

Here's what it actually looks like, "unplugged"--quite unobtrusive when "plugged in", just the red tab shows :

 

I am doing well, thank you for asking... The good part is I have an official document stating I cannot wear a seat belt.

Hi Cliff, I'm happy to hear you are doing better after your surgery.

I would be interested in obtaining a seat belt eliminator as well.  That is awesome that you make one.  Can you let me know where to send a SASE and the cost please?

Thank you for offering to make these for folks.  It is appreciated.

What is the top speed for the Hisun 400

[Manfred]

Mine goes 50 mph

Take the seat belts & attach them to each other, a criss cross system & they work fine & do NOT bother your back because they are together in the middle of both seats.
