I've found mine must be creating vacuum in tank.When it starts to die loosen fuel cap for a second then tighten again.And it works fine till it makes another vacuum.Not sure how to remedy this as yet.

I have just purchased a UMK 435U Honda Brushcutter, what a great machine.
What sort of oil goes in the gearbox & how do I know how old the model is.
Where do you get the user manual from.
Thanks.

I have a replacement line head unit but it’s much bigger than the old one.
How do you remove the line head, there is no Allen key like the older units.

1 answer

From memory (been a while), there's a hole you stick a screwdriver or Allen key in to hold the shaft while you unscrew the head. It's usually buried and hidden in grass so you may need to clean things a bit to find it. :-)

I have 2 Honda UMK435T trimmers. I have had to replace the clutch shoe TD40 in both units and they are less than 8 months old. Why do they wear out so quickly?

Trimming head speed too slow, causing clutch slippage

how to grease the hub of Honda 435 T brush cutter?

Hi. To my knowledge the bearing and spindle head unit are factory greased and sealed.
My 35 has been used on my small acreage every weekend and for many years.
The head unit still spins smoothly and has no shaft play.
I would think I will wear the motor out first.
I am sure your Honda dealer could effect repairs when and if needed.
For me I will just park it up and buy another Honda.
They are so reliable.

While re assembling the nylon cutting head, I have placed the holder upside down and therefore when I insert the alan key into the cutting head, there is no slot for it to lock into.
How can I remove the cutting head and place the holder the correct way around?

Place the holder in a vice and undo the cutting head, or use a pipe wrench on the holder to hold it firm. Remember it is a left hand thread.

Try putting compressed air through the fuel tank filter.

Sounds like the vent valve on the fuel filler cap is blocked.
Try starting it with the cap loose. If it runs smoothly you would need to air dust the cap or wash it in some petrol.
Cheers.

Hello
Managed to get hold of one of these awesome machine after submitting a winning bid at an auction. The choke has been a little sticky, but currently have cleaned a lot of the parts. I will be reassembling the machine parts over the next couple of days after parts have had a chance to dry out. Does anyone know how many gaskets are on this model as I ma considering replacing them.

Regards

John

Hi I was brush cutting this morning and for the first time ever my machine cut out. I went to restart it and the chord won't pull out to start? I'm gathering it must be caught up in the gearing somehow. Any ideas for a home fix? Cheers, Greg

I believe your motor might be cooked beyond repair. Most likely a lack of oil, or dirty oil. More expensive to fix a seized motor than to buy a new one. Sorry.

Why the engine has not enough power to supply when cutting grass, and the engine stop?

4 answers

G'day Fraser, there could be any number of reasons for the engine losing power and stopping, but I always check the easiest (and cheapest) solutions first. In this case they would be the air cleaner and the fuel strainer, both of which you can service yourself (instructions are in the manual).

By the way, my wife complained of something similar one day, it turned out she had just left the choke on. I still give her a hard time about that.

I have had the same problem with my Honda brush cutter. Did all the maintenance jobs in the manual but although improved it never fixed it. It is always worse when cutting long or thick grass. It always seemed like it wasn't getting enough air but changing the air filter did not fix it. Loosening off the petrol cap fixed the problem but the cap then fell off with vibration. Yesterday I drilled a hole in the centre of the petrol cap and it has never worked better. I can rev it up as much as I like and it never cuts out. However not really knowing much about engines I wanted to ask if the air was being limited for a reason. What I have done now means that I can cut flat out but will it damage my engine?

JohnS

Hi Annie. Had the same issue. That fuel cap is supposed to be vented but the tiny hole blocks up. The engine can't keep sucking fuel (especially when working hard) if there is a vacuum developing in the tank. So yes, you're on the right track. No issue with drilling a hole unless it is so big that junk gets in the fuel.

Im looking in the manual and cant find nylon line size, can someone tell me the size instead of just a colour please?

The thickness of the line doesn't matter. The length of the line is limited to how much you can loosely roll on - I get about 2.8 metres on each time.

You can use up to 3mm. I use it all the the time. It lasts longer than the thin line. I assume that because you have that model you would be cutting more than grass at times, so use the 2.7/2.8 mm or 3mm and you should be fine

I had a quick look through the product manual that came with my trimmer(UMK435) and couldn't find any specification for the thickness of line. That said when I purchased my trimmer I asked about the line thickness and ended up getting a spool of Honda brand line 0.27cm (2.7mm) in thickness This is really good stuff it has a squarish profile with edges on each lobe and cuts really well. I would normally use diamond line orange 0.27(2.7mm) on my sthill and was planning to use it on the Honda but I will probably stick with the Honda stuff there would seem to be very little difference between the 2 in my opinion.The Honda line is white in colour and the diameter is marked on the packaging as 0.27 (2.7mm) line. I can t actually tell you if I got more line on the spool that I would have if using the diamond line I didn't measure it (or have tried it yet on the Honda)The profile shape will actually assist in determining the actual amount of line you can spool but I don't think there would be much difference between these brands when it comes to it. It would only be centimetres if it was different The Honda line is dearer compared to diamond line but the pricing would be under $5.00 per spool in difference. Where you buy it from will also determine price etc. The original line supplied with the Honda( on the cutting head) when I got it was round and thicker and very soft (also white). It was ok but it didn't last too long I remember having the same experience with the original line that came on the sthill when I bought it back in 1995. I use my trimmer in a variety situations e.g. trimming concrete edges, retaining walls, heavy grass, some undergrowth, around poles etc. This diameter of line is a good all-round, from experience though If I were going to do a lot of clearing I would go up to 3mm line Hope this helps.
