@12:50. The piston is riding on that oil so it doesn't make contact with the aluminum body, just like a car motor piston. Nice to see the breakdown.

[@DudleyToolwright]

I agree and thanks for the comment.

[@jflorex867]

Thanks for the demo Robert, not your the fist KZbinr that brakes down equipment and shows what and how it's made, and how it works. For my use I better look for an upper end like mikitak, bosh or craftsman jack hammers.

[@DudleyToolwright]

You are welcome and it makes sense if you are going to use it often. This too is for the occasional user.

[@frankward709]

What's a little pipes to put the tools in Little bungee cords around it you can wheel it up with put it in the truck and head out 2nd part of my 1st statement

[@henrygin3296]

I made a motor speed controller to get the best hammer power and put a bit of gress/oil in the bit holder and the thing runs very well

[@DudleyToolwright]

That is an interesting tip. Thanks. I'll give that idea a think.

[@bigviper64]

Just bought ours, to break up Limestone Rocks..I’m praying that it works as well as with Concrete!

[@DudleyToolwright]

Best of luck. I am sure people would love to know how well it works out.

[@frankward709]

I wouldn't got one of the metal Harbor freight hand trucks well do the pay gone there and then put all the implements around it Thanks for the video

[@DudleyToolwright]

Excellent idea. If you buy the current Bauer Jackhammer from the Harbor Freight, it comes that way. very useful. Thank you.

[@christophercullen1236]

Robert when you do hardest testing on castings you have to grind a 1/16 " deep pad to get below the chilled surface on the casting which happens during the pouring operation. It can be like glass some times , a better result would have been on the machined part . ( 50 years in Foundry game o my backs sore. ) Christopher from Down Under

[@DudleyToolwright]

Thanks for the tip. I think an ideal chisel for a jack hammer might be surface hardened to resist wear and a soft interior to have good toughness. However, I am by no means an expert on the topic, so take my opinions with a grain or five of salt.

[@AyalaJD2730]

Thank you for the review, i wish someone would compare the 2200w vs the 3500w because just saying one is stronger than the other is not really good enough

[@DudleyToolwright]

That would be a good test and I wondered about the very same thing when they offered me the unit to review.

[@U2BER2012]

Vevor recommends: Petroleum based, ISO VG46 hydraulic oil; which is very hard to find. So I ended buying MV46, which is a synthetic oil and has additives meant for use with high heat applications. From what I've read; MV46 is superior to VG46.

[@DudleyToolwright]

Very good to know. Thanks for sharing what you've discovered.

[@SuperHaptics]

Is it not true that small size internal combustion engines 50-150cc have aluminium cylinder where an aluminium piston runs with steel rings? or all engines are steel lined?

[@DudleyToolwright]

I am far from an engine expert, but I have never heard of an engine where steel rides on aluminum. That would be a recipe for a very short life span.

[@dougrichardson1980]

The manual says not to use too much oil or it could damage the product. The manual does not say how much oil to put in it. Did you figure that out? And is the site glass supposed to be viewed when it is in a vertical position? This looks like a great product, but the user manual is not very informative.

[@DudleyToolwright]

The user manual could have been better. I guessed on the amount of oil, based on the site glass and guessed that it should be vertical to measure.

[@dougrichardson1980]

@@DudleyToolwright the company responded to an email that I sent them. I asked them about the oil and they said that you do not have to put any oil in it when you buy it brand new. You use it for 20 to 30 hours and then add 30 mL of oil. 30 mL of oil converts to approximately 1 ounce. So apparently, you just add 1 ounce every 20 to 30 hours of use.

[@M70ACARRY]

The manual states to add 20-30 grams of oil every 20 to 30 hours of use.

[@kentuckytrapper780]

Good honest review, thanks.

[@DudleyToolwright]

No problem! Thanks for watching.

[@TheKnacklersWorkshop]

Interesting review Robert, thank you.

[@DudleyToolwright]

Thanks for watching!

[@RF-kz2sz]

How many ounces of oil do you add without taking the cover apart?

[@DudleyToolwright]

I would guess around 4-6oz.

[@NotRiansLuke]

Great review, thanks!

[@DudleyToolwright]

Glad it was helpful!

[@alan2112drums]

What kind of grease did you add?

[@DudleyToolwright]

Molybdenum DiSulphide Grease.

[@bdbdwd]

What parts did you apply the grease to ? Just ordered one .

[@DudleyToolwright]

I put grease on every part in the mechanical end of the jackhammer. The motor side has a ton of empty space inside and it seems it would be hard to direct grease to go anywhere specific.

[@bdbdwd]

@@DudleyToolwright Thanks for the reply gonna pick upa tub of moly today .

[@dougwalk8034]

You don't need grease on anything for awhile, just cheap tranny fluid to fill the sight glass !

[@memoirsofmonterey3620]

How many amp circuit?

[@DudleyToolwright]

20A

[@jpsimon206]

I suppose you could custom make the world's least convenient biax scraper?

[@DudleyToolwright]

Excellent idea...heavy cutter.

[@cyril.engineering]

It seems if I post about an orange local hardware store, my comments get scrubbed.. I actually bought one to pour support for bigger machines! Have at you! However. If you buy the XtremePowerUs label from *redacted* you get warranty for months, no questions asked.

[@DudleyToolwright]

That is really unfortunate. I am aware that a channel moderator can delete posts, but you are suggesting "help" from KZbin?

[@cyril.engineering]

@@DudleyToolwright correct! The posts were immediately scrubbed. The only thing to change was removal of said name.

[@mihaiilie8808]

Its a copy after a Hitachi jack hammer but the chinese made it even more powerful. Lately even Bosch got to steal the design for their newest, brushless jack hammers. Its extremely cheap but it worth every penny. A friend has one for about 10 years or so and used it to rral barbarian work and borrowed to all his friends. Only had to replace the brushes. Its a professional tool except it lacks the name brand.

[@DudleyToolwright]

That is really interesting additional information. Thanks for sharing it.

[@jpsimon206]

I have a Harbor freight jackhammer that is electric, I bought it for one small job. The bits all seem to be made out of cheese, but it took standard fittings so I was able to get quality bits for it. This is before the days of Bauer, it's a very strong smelling orange plastic from Chicago electric. It's a horribly designed tool with awful balance but I have to admit, it's going on 10 years and while it has never worked what I might call very well, it's also never let me down. Not something I reach for very often, but a pretty surprising lifespan for Harbor freight. I'm completely new to this company vevor but I've seen a handful of tools from them now that make me assume they are on a par with Harbor freight's higher-end lines

[@jpsimon206]

One caveat that might be relevant, on most of my handheld power tools, I use a piece of pantyhose as a pre filter for the air vents. Obviously I'm biased, but I'm personally convinced this will make any tool last longer than it would otherwise

[@DudleyToolwright]

Great tips and observations as always. I went to Harbor Freight yesterday and their new jackhammers look pretty nice. The outside quality seems to be a step up from this one, but I did notice similar extruded aluminum driver tubes on some of the models.

[@douglasthompson2740]

This country uses 60 Hz not 50Hz. Did they make an appropriate model? I know you can't complain when they are giving you stuff.

[@DudleyToolwright]

Oh, but I can. It works fine on 60hz the motor rpm is likely different. Good observation.

[@dray7579]

Lol, i bet vevor didn't see this coming.

[@DudleyToolwright]

They put no restrictions on my reviews, but I am not sure what they expect. In any case I do my best to be impartial.

[@ovoono4484]

You dont need to press it so hard

[@DudleyToolwright]

Good to know. Thanks.

[@Saileahgaz]

These tools are unreliable. That's their biggest issue. When you contact the company about a problem you're having, they just offer to send you parts so that you can fix their low quality products. Expect to have your request for a refund ignored and for the replacement parts to take weeks to arrive. If you're going to roll the dice and purchase cheap tools, at least buy them from someplace that will offer a warranty of some kind.

[@DudleyToolwright]

You approach seems reasonable and I don't even disagree. What I try to do is find the occasional gem.

[@honeycuttracing]

Cheapo brand, bought a air over hydraulic 20 ton bottle jack for our shop press, was filled with brake fluid not hydraulic fluid and plenty of grit from manufacturing, had to end up taking it apart and clean it!!! Won't be buying this brand of anything again!

[@DudleyToolwright]

Very useful feed back. Thanks for taking the time to share your experiences.

[@dougwalk8034]

I used cheap walmart tranny fluid for mine and it worked great, don't be fooled into spending a ton on hydraulic fluid !!!

[@DudleyToolwright]

That is a great tip. Thanks.

[@M70ACARRY]

Actually, type 46 hydraulic fluid has specific additives. I trust the actual engineers and not some KZbin commentary.
