These batteries have big problems that Hitachi doesn't address very well. Unlike NiCad batteries, Lith-Ion ones must be periodically used and recharged to retain their battery functions, i.e. if they have been sitting on the shelf at a store for an extended period of time, chances are they will be dead when bought and will not accept a charge. If they go dead i.e. no little red light on the charger when you plug the battery unit in...it's basically junk.

If you can return them or exercise the warranty do so. If / when you get new ones DO NOT completely discharge them like you would NiCads. Lith-Ion batteries do not have the "battery memory" issues that NiCads have which means you don't lose running time if you don't fully discharge the battery unit prior to recharge. Completely discharging before recharge will ultimately kill them. Use the 1815X till almost dead and then charge it. It is also recommended Lith-Ion batteries not be stored fully charged i.e. charge the 1815X fully, drive a couple bolts or screws, remove the battery unit and then put it away. Do not leave battery unit plugged into the tool when you put the tool away. This will discharge and kill the battery unit.

There are non-Hitachi substitute batteries now on the market. I'm guessing the same precautions apply but I don't own one of the replacements so I don't truly know.

The actual batteries in the Hitachi BSL 1815X are Sanyo UR18650SAX lithium ion batteries. Lithium Ion cells aren't all that easy to get commercially because of handling & safety requirements. Not certain if you can take apart the 1815X and swap out the bad Sanyo cells.

the red light turns on automatically after 120 hrs of running to remind us for cleaning the filters. once you cleaned the filters and inserted back , then just keep ac in stand by mode, open the remote panel and press the button on extreme right bottom of the remote ( see carefully in the remote, there is very light image of the filter is made along with the button). red light will go off. no need to press the reset button.... enjoy

Simple question, is there something inside of the blade and the blade guard blocking its use? Sometimes a piece of wood or plastic lodges itself in between and is hard to see.

It is a disk error! Change the disk you are using, probably you are trying to use an RW disk! Better +/-R.

Your description makes it clear that it needs a head rebuild kit. You can order this from Hitachi, or send it in to local Hitachi center. Good machine, straightforward repair. If you are a little handy, you can do this repair yourself. remember to oil the gun frequently to make your repair last longest. Farmerbear at FixYa

As this item is within the installation menu, you need a remote control.

First make sure that the current Source or Input is set to TV. This is usually the only reason for the error message you see. To select the source, look for a Source or Input button on the original remote. If you have an universal remote with a button with the Source/Input label, you may need to try alternative codes to make the button work. (Power and channel controls will often match across multiple codes for the TV manufacturer.) Alternatively, check if there is a Source/Input button on the TV or a section of the menu system with the function. Once you set this source, try again.

Note: there was a period when manufacturers sold some TVs without tuners. They were labeled HD-ready sets. These can't do a channel scan and do not have an RF antenna jack on the set.

I hope this helps. Please add a comment with the model number of your Hitachi TV for more information on setting the source on your set.

Depends on the model number.

Turn everything off, including the outside unit for an hour. Then switch it back on. If that doesn't reset it, you need a service call.

Under Audio or Audio Settings on the on-screen menu, TV Speakers is set to On. All of the cables physically connected to the TV and the input devices are secure. Switch to a different input device and verify there is sound from the TV speakers (for example, a DVD player or a gaming console).
