What oil should I use if Hitachi oil isn't avalible?

On both the V6 and V8 engines the Oil Sensor is located on top of the engine at the rear. You will need to remove the top of the intake manifold to get to it.

OIL ?? I think Hitachi has always a yellow grease lubrication
hitachi grease demolition hammer Google zoeken never seen heart of oil in Hitachi demolitions. but there could be models in your Country thats new for me .
Otherwise BOSCH HILTI and the one and only brand DUSS demolition hammers and also a few brands of Chinese hammers need oil lubrication . an expensive sinc-free hydraulic oil the same as used in some pressure washers life lasting oil but for HItachi look at the link for the grease 2 tubes a enough . good luck and dont forget the piston pin to replace with a new not only the gaskets and o-rings and also the oil and dirt seals on the front where the striking pin is that must be absolutely not air leaking because all your work burns in a few months again out . you can start all-over again.

Needs very little oil, just few drops of sewing machine oil or nail gun oil sold at lowes or home depot. Purchase smallest size bottle of Paslode or bostitch nail gun oil (most likely they will not have hitachi oil). Do not by air tool oil as this oil is for air powered impact etc. Good luck

If your magic focus is not working your convgence has failed. Read this Tips page here on fixya for more details.

after you have cleared all the obvious stuff aka; bar hole, oil outlet, etc, look inside the oil tank to find the oil pipe and screen, if they are intact and not clogged the "O" rings on the adjuster are bad. If not clean the little screen and replace the oil pickup tube, yes they are still avalible. It's a bit tricky but can be done through the oil fill cap hole.

Hitachi hammers use 30wt non detergent oil. But you can use lighter oil in cold climate. If too much oil accumulates in hammer, it may just come out bit retainer or build-up inside gun. Oil enters the hammer by wick process, of wick is missing oil will enter too quickly. If your brand label is glued on, you may have a hitachi copy from china (most hitachi labels are rivited on). China hammers may use different oil.

Use 34 degree, paper collated, clipped head nails. They were always the most common strip nails years ago as Senco, Paslode, and a number of other nailers used them.

Hi Welcome to Fixya!
Your hdd is making that sound mainly because it could already be damaged inside. That is also the reason why it is not being detected by the computer.
Same thing happened to me with my 120gb Seagate Barracuda.
Consider in replacing the hard drive on your computer.

Hope this could help!
Have a great day!

The oil cooler, a gasket and o ring is avalible to repair. I would use dealer parts.

Hitachi sells a pneumatic oil for use in its air power tools. Your local Hitachi dealer, or any pneumatic dealer will sell the oil. The brand is not as important as using a few drops directly into the air fitting when starting a day of work. If used heavily, oil it again mid way through the working day.
