+1 on Chinese sparkplugs. They seem not to transmit the energy to their electrodes, I'm not sure why, but there's no doubt there's some sort of issue with them. Just change them to a NGK. The choke required is also a common complaint - the carb needs to be richened up a tad, a common thing with offshore engines, I think they use slightly different fuels around the world, and equipment comes tuned (if it is at all) for whatever fuel they have available in that country. Avoid ethanol fuels as they are even less energy dense, and come with all the other ethanol issues, most of which really come to bear in cases where there's long term storage, as is common with breakers.Thanks for the review, it's helpful.
OK, about the gear grease: Research shows that the #1 and #1.5 in the manual refers to the NLGI grease consistency rating. Any extreme pressure grease with that consistency rating should be fine.
Nice video. I just bought what looks like the same unit to break up concrete. Have you put any lube in the gearbox yet? If yes, what kind? The manual says #1 or #1.5 grease. Can't find anything with that designation. I like to have maintenance supplies on hand before they're needed.
A marine grade corrosion protection grease like those designed for boat trailer wheel bearings is best, it's keeps everything from rusting, as with tools like this, there is a good chance you'll be working in water eventually, the water gets in even if you have good seals, which most breaking hammers do not. They also are often used for short jobs and don't warm up enough to drive off any condensation that may accumulate. Corrosion is the #2 killer of seldom used equipment and foul gasoline is the #1.
Hello, I wonder if the throttle is set like that on purpose. So you can set it and then grip the handles with both hands and use your thumb. Did it last through the project?
SuperJamster1 maybe they did intentionally leave it off because it is functional like it is, I would just rather have it return to idle when I release my thumb, and yes the jackhammer is still running as good or better than new, it was worth the $200 we paid, thanks for the comment and I hope you enjoyed the video!
@@ThaoUSA it sure is better then buying a generator and extention cords and electric jack hammers wich is way more money wich im kinda looking at a gas powered jack hammer

Can you use this in confined spaces like a mine or tunnel. I am wondering if the exhaust can be extended using a hose pipe to take fumes outside the mine.
It affects the parameters of the engine and cannot be used. However, I recommend a Milwaukee MX Fuel Jackhammer or a pneumatic jackhammer for a mine or a tunnel.
If it’s outside then you could use this but I wouldn’t want to run a 2 stroke motor indoor very long, this machine would make pretty quick work out of concrete though I’m sure of that.
maybe 20 hours so far, I also used it to drive two 8 ft. grounding rods for new electrical service, still runs great, I don’t anticipate it will last thousands of hours, but it has already paid for itself.
@@NoNopeAndNo it's alot cheaper then the jack hammers wich needs generator to plug it into the gas powered ones deffently fixes that plus its bit lighter then the electric ones
