I've seen a number of requests for the location of all the grease points on these machines, and there is no definitive list in the manual. This covers the UT400, but other Coleman/Hisun models should be similar.
Tools:
First to grease your machine you need a grease gun and some NLGI#2 grease. You will find it helpful to buy a needle attachment as pictured here, due to poor clearance on some of the U-joints. The rest of the zerks use the standard attachment.
Technique:
Wipe any dirt/grease off the zerk before greasing to prevent pushing gunk inside and causing excess wear.
Push the grease gun on the zerk at a straight angle and give it a few pumps. You will hear an oozing noise or sea grease coming out from the outside of the greased area when you've put enough grease in, a few pumps should be plenty.
If it's just oozing around the zerk you either don't have a good seat with the gun, or the zerk may be rusted and the check ball frozen. Try seating it again and regrease.
Wipe up any excess grease when youre done to prevent making a mess.
Greasepoints:
Rear A-Arms are greasable with the wheels on from the rear, I took the picture with the wheel off for easier visibility
That's it. All other Hisuns should be substantially similar.

Hello to anyone who reads this. I am Jon and I own J&M Outdoor Power, a very small, small engine repair shop. I was approached by Coleman about 6 months ago to become one of their Warranty Centers.
I recently received 3 different UT400's and a UT500 all with similar issues. These units range from 2 months to 2 years old. Customers state that the unit(s) was/were running fine, then heard a pop and a loss of power, two would no longer start. The two that would run would not achieve normal operating speed (around 20mph I would say) without redlining the RPMs. I quickly found that the Valve lash on each unit had become too large on some(both intake and exhaust) and too tight on one(just intake).
After setting the gaps to .005(I found multiple different people suggesting bigger and smaller gaps, but no definitive Coleman Spec number yet) every unit starts, runs, and achieves top speed without issue.
I don't know how many others have come across these issues, and I wanted to get something out on the web for others in the same predicament.
Please let me know if you have had similar issues.
Edit: I realize that this will not be a fix all solution for this issue, as the oil level and condition should be verified before moving to the valves. Many times improper oil conditions will cause valve lash to change. These units all have good oil and proper oil changes.
