20 Most Recent Hitachi Nip Service Kitoverhaul Kit For Dh38ya Questions & Answers


This hammer may not need parts replaced. If it has not been serviced in a while you may only need to take apart lower half of hammer and wash out old grease and replace with either hitachi, bosch, dewalt, or skil grease. You can even use some skil worm saw lubricant sold at Lowes. Just clean and lube more often. This hammer works with air cushions action. The motor moves the piston and air trapped between the piston and striker moves the striker against the second hammer. This system does not work well if the grease if too thick or dirty or if the hammer is stored with bit facing up in the air. If parts look well lubed then may be issue with bit or second hammer may be stuck. Do not use bits with missing pieces or that have been ground where the second hammer strikes. Parts that need to be replaced will be obvious. But generally clean and lube will do the trick. Good luck

There is a sight glass on the side for you to see the oil level. Make sure they are always checked. You can buy the oil at any service center. Hilti makes oil too and can probably be purchased at Home Depots. Also the Home Depots that have tool rental programs would most likely sell the Hitachi oil too.

For most climates a good oil to use is air compressor oil (mineral). Sold at Lowes and many other stores. It has great lubrication properties and can take good amount of heat. In very cold climates where oil could thicken, store hammer indoors to keep warm until ready to use. Good luck

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.

In most brands of this breakers there is no oil used , (only if there is an oil sight glass on it) some rotary hammers or breakers with high rpm have oil lubrication ( in most case its a sinc free hydraulic oil) (or special Turmopol oil (by Hilti) but this kind of hammers have no high rpm for oil and i think its having a normal grease lubrication and its enough for replace the grease after the carbon brushes are short and the tool stopped working then its time for service o-rings and seals and grease for the next service by the ALdi service.??
