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.

Remove chuck assy and see if it will release, it might need a bit of help with a vice. If not then it will have to be taken apart and pressed out.

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.

I have seen many versions of this hammer with many different mfg names. I believe that this is a China copy of a hitachi hammer. No parts are available for this tool. The tool looks substantial from the outside, however internal parts are weak and break/burn out very easily (unlike the Hitachi/Japan version which is a workhorse, years of use before failure). If your hammer is china version, do not invest any more money because other parts will start to fail (most fail within short time from motor burn or broken parts ).

Demo hammers do not oil/grease the bit. The grease in the tool is to lubricate and cool the parts in there doing the hammering. The bit should have grease on the end going into the hammer to make it work in the tool better and make it easier to take out when you are done. You have to put the grease on the bit yourself.

Large hammers have an air driven piston (an air cushion betweem pistons) and an intermediate anvil that actually hammers on bit. If the cylinder and air cushion piston are dry there will not be enough suction/pressure between the driver piston and driven. Remove lower part of hammer and lube with electric hammer grease. Make sure that orings fit snuggly and the anvil is not jammed. Do not store hammer with the bit pointing up because the driven piston will slide down cylinder and hug driver piston. If the hammer was stored pointing up, turn hammer around and place in stand with nose down in a warm location so that the driver piston will drop into place. Good holidays

did you have the trigger in the locked position, some tools have a safety that you need to release the trigger after plugging back in to reset the switch. try that first.

Sounds like the bit bent slightly and as a result jammed into the chuck. Open chuck as much as possible and have someone pull the bit out while your tapping it with a small hammer. The vibration from the tapping might loosen the bit from the chuck.
