Hitachi f381a remove cover

Unscrew the rocker cover and remove the top casing, most cars now have gasket seal rather than a gasket so check this. Put new gasket in place and then replace top casing, replacing the bolts back in the order they should be in, then put rocker cover back on...

There are two small black phillips screws near where the cable is, take those out. The opposite side from the screws is the cover, it pries off. You can work a flat tip screwdriver in there and see if you can pop it off without damage. Start on the sides.

If you're having trouble with that you can remove the rubber piece going around the outside first. I started where the floppy opening is, you can pry it out with a small flat tip screwdriver then just pull it out. Do the same for both sides of floppy opening.

Then you'll have to take the phillips screw by the motor to remove the drive from the case. There is another small phillips screw holding the cover, remove that and you can work the cover off. Now you can clean the heads.

To put it back together screw the drive cover back on, then screw it back into the case. Put the rubber piece in, then push the top cover back down till it snaps in. Then put the black screws back.

Over time debris enters the gun and scratches the metal and plastic surfaces where orings seal against. These scratches will allow air to leak past. Remove the head and pull out the head valve. Examine the metal surface with magnify glass where the headvalve oring makes contact. Remove scratches with 400 grit paper. The surface must be smooth and the oring must seal snugly. Apply silicone paste lube on all surfaces and orings (available at Lowes in the plumbing department and swimming pool supply). Also check for scratches around the body of the gun were the cylinder plate is installed around the cylinder. The gun will not work properly will small air leaks. Remove nails and listen for leaks thru the nose of the gun. Repair as needed. Good luck with your gun.

Hello,

The problem is a hardware problem, which is due to a failure in a component it the unit.
You will have to dismantle the playstation, clean it and couple it back together. To dismantle the playstation, follow the steps below:
1.

Pull the warranty sticker off of the bottom of the PS3. This will void your warranty, so make sure that the problem you are addressing is not covered by your warranty. Note that taking your PS3 to be repaired by someone other than Sony will still void your warranty. You are not losing anything by taking apart your PS3 yourself. Under the sticker will be a small piece of rubber that hides a single screw. Remove the rubber piece and unscrew the screw.

2 Slide the faceplate off of the PlayStation 3. After the faceplate is removed, you can now separate the two halves of the plastic covering. Remove and set aside the top piece of the plastic case to expose the internal components of the PS3. On the underside of the top plastic covering, there will be a memory card slot at the bottom-right corner.

3 Locate and remove the Bluetooth circuit board. Remove the four screws to lift the Bluetooth board free. This is located at the bottom-left corner of the main body of the PS3 if you have the system flat on its side instead of standing up straight. This will look like a green rectangle with a tan metal covering.

4 Locate the small circuit board that controls the power and eject functions of the PlayStation 3. Remove the four Phillips-head screws in order to separate this piece from the body of the system. This is located at the bottom-right corner of the PS3, directly in front of the disc box.

5 Locate and remove the Blu-Ray/PS3 player. This is the large tan metal box that is located in the top right corner of the PS3. Unscrew the player and flip it upside down to expose the circuit board that controls it. If you want to remove the circuit board, there are five small screws that hold it in place.

6 Remove the power supply from the inside of the gaming system. This is located at the top-left corner inside the PS3. To remove this component, there will be two telephone-like plugs that have to be unplugged, one at the top and one at the bottom of the power supply. Additionally, there will be 13 screws that hold the power supply in place. The back and front plastic coverings of the PS3's shell will now easily slide free.

7 Remove the final internal component, which is the PS3's motherboard. In order to do this, remove the metal covering the rests on top of the motherboard. There will be 11 screws that border the metal covering as well as four screws in the very center, two from each of the rectangular center pieces. Once the screws are removed, the metal covering will lift off and the motherboard will be able to be removed.

Have it cleaned and properly reverse the process to reassemble it back together.

Note: If you are still under the warranty period of purchase, you can take it back to the dealer that supplied it to you for their technical support.

Take care and good luck

Hello,

Take care

To service the ink tanks:
Ensure that the printer is on, and then open the Top Cover.
The Print Head Holder moves to the center.
Note
If the Top Cover is left open for more than 10 minutes, the Print Head Holder moves to the right. Close and reopen the Top Cover to return the holder to the center.
2 Open the Paper Output Tray.
Put your fingers in the notches in either side of the Paper Output Tray and pull down to open it, and then pull down the Inner Cover forward to open it.
3 Remove the ink tank whose lamp is flashing fast.
(1) Push the tab and remove the ink tank.
Do not touch the print head lock lever; remove only the ink tank.

Important
Handle ink tanks carefully to avoid staining clothing or the surrounding area.
Discard empty ink tanks according to the local laws and regulations regarding disposal of consumables.
Note
Be sure to replace ink tanks one by one when replacing more than one ink tank.
4 Prepare a replacement tank.

* Do not touch the electrical contacts on the ink tank. Doing so can cause the printer to malfunction or become unable to print.
(1) Unpack the new ink tank and completely pull off the orange tape. Then, remove the film.
(2) Remove the orange protective cap from the bottom of the ink tank and discard it.
Important
Be sure to remove the clear film from the ink tank in the exact order shown in step 4-(1), as failure to follow this step may cause the ink to leak and stain your clothes and hands.
Do not squeeze the side of ink tanks as this may cause the ink to leak out and stain your clothes and hands.
Do not re-attach the protective cap once you have removed it.
Do not touch the open ink port once the protective cap is removed, as this may prevent the ink from being ejected properly.
Ink on the removed protective cap may stain your clothes and hands.
Ensure that all the orange tape has been peeled off along the perforation. If there remains a part of the orange tape, ink may not be output correctly.
5 Install the ink tank.

(1) Insert the ink tank into the Print Head.
(2) Press on the mark on the ink tank until the ink tank snaps firmly into place.
(3) Ensure that the ink tank lamp lights red.
Important
Ensure that all the ink tanks are installed in the order directed by the label. The printer cannot be used unless all the ink tanks are installed.
6 Close the Inner Cover.

Note
Ensure that the Inner Cover is closed. Printing will not occur if the Inner Cover is open.
7 Close the Top Cover.
The Print Head Holder moves to the right. The ink tank installation process is now complete.
Note
The ALARM lamp still flashes orange after the Top Cover is closed if an ink tank is not installed properly. Open the Top Cover and make sure that all the ink tanks are installed in the correct order directed on the label.
To maintain optimal print quality, use an ink tank within six months of first use.
Once an ink tank has been used, do not remove it from the printer and leave it out in the open. This will cause the ink tank to dry out and the printer may not operate properly when it is reinstalled.
Color ink consumption may occur even when black-and-white or gray scale printing is specified.
Color ink is consumed in the head cleaning and deep cleaning, which are necessary to maintain the printer.
When you start printing after replacing the ink tank, Print Head Cleaning is performed automatically. Do not perform any other operations until the Print Head Cleaning finishes. The POWER lamp flashes green during cleaning.

If you have gone through the process of cleaning and deep cleaning, as described by canon, and you still get no ink flow after printing 2-3 pages, the print head needs to be replaced.

Need more info such as is it a 2 head or 1 head. Have you removed the screen and diffuser to see if its clogged, do you hear the pump when you run the head. If yes to all then on top of the group, if you remove the front cover, and the sheet metal plate you will see a nut a 17 or 19mm open end wrench will help you remove it(MAKE SURE WATER IS TURNED OFF AND THAT THE MACHINE IS COOLED BEFORE OPENING). The micro filter and the jet will be covered with minerals clean filter and use a paper clip or long pin to clean the small hole in the middle of the jet.

I know my response is a while after you asked, but to clean the inside of the tv case is pretty simple.

Remove the bottom speaker cover...on this model you just pull it off. There is no clips or screws.

Once the speaker cover is off you will see the bottom of the screen, there is 4-5 screws on the bottom on each side....I think 4 in the gray plastic and 1 in a black metal strap. With all of those screws out pull out SLIGHTLY on the screen and push up. The top is held in with a down force clamp and you are just popping it out of that....It will pop back in once you are done.

Now clean the back side of the screen, the mirror and CAREFULLY dust off the lenses. I myself did not want to use any cleaners (to avoid streaking) so I used a new microfiber dusting cloth. My picture became brighter and the "crack" that I thought I had was just a dust web....

Hope this helps and good luck
