Hello. The C12FCH laser unit is housed in the base of the saw housing and has a part No. 323-647. Just a quick check though, are you sure it's the laser module itself and not the laser switch? And have you checked that the lens is free of obstruction? Here's a link to the parts list (blown up, not in fine print like in the manual):

Hope this helps, don't forget to rate us for assistance.

Thank You.

    The Laser Module, part no. 323-647 is listed as no longer available

  • Richard Crate Mar 21, 2011

    I am attempting to track down replacement parts information for you and will post back to here when I recieve it. I have also questioned them about this part being discontinued, yet they are still listing the saw as active. Hopefully the information/answer will be in before the week is over.

    I'll do what I can.

  • Richard Crate Mar 22, 2011

    I have tracked the information you need. The replacement part is actually the "module" and has a different part number - 324-711. Ordering directly from Hitachi is going to involve company registration, so I would suggest (and so did they) a retailer/service co. near you. The locator link is:

    Shipped out by Hitachi, the unit will be aprox $70.18 shipping ($15-$20). The shipping can be saved from a retailer b/c they get a discount price and better shipping rates.

    Thanks for being patient with this response, and I hope I've been of assistance. Please feel free to rate this answer.

I have a 99 Pontiac Sunfire, 2.2L and my turn signals quit working. I replaced the combination switch and the flasher/hazard relay, and still no joy. The problem was intermittent, and now it's just dead....

It will turn on when I hit the button and the turn signals do work. All of this has led to my ABS lights to come on as well. ??????????? Your best bet , take it to a qualified repair shop or learn to do better explanation's ! Or lean to do automotive electrical testing .

Under system click on lighting ,then under subsystem click on turn signals . Click the search button then the blue links .Check power an ground circuits ! This is how we diagnose electrical faults , not just replacing parts .

Turn Lamps
Voltage is applied through the TURN fuse and the turn/hazard flasher when the ignition switch is in the following positions:
The voltage travels to the contact in the hazard switch. The hazard switch is located in the turn/hazard-headlamp switch assembly. This contact is normally closed.
When the left turn signal is turned on, voltage is applied to the following components.
• The left turn indicator
• The left front park/turn lamp circuit 14
• The left rear turn lamp circuit 18
The turn lamps turn on immediately. The current flow heats up the timing element. The timing element is located in the turn/hazard flasher. The timing element repeatedly opens and closes the circuit. This action causes the turn lamps to begin flashing.
The voltage that is applied to the left front park/turn lamp is also applied to the left front marker lamp. If the headlamp switch is in the OFF position, the left front marker lamp will find a path to ground through one of the following lamps. The following lamps provide low resistance paths to ground:
• The right front marker lamp
• The right turn indicator
• The right front park/turn lamps
• The left front park/turn lamps
The left front marker lamp flashes with the turn lamps. The voltage drop across the marker lamp is much higher than the voltage drop across the other lamps. The lamps that are used for the ground path will not flash.
When the headlamp switch is in either the PARK or HEAD positions, voltage is applied through the following components:
• The EXT LP fuse
• The marker lamps
• The park lamps
When the left turn signal is turned on, the left marker lamp will have voltage at both connections. The left marker lamp does not light. When the turn/hazard flasher stops the voltage to the turn lamps, the marker lamp is grounded through the turn lamp. The marker lamp does not go on. The left front marker lamp flashes in the following manner:
• The left front marker lamp flashes on when the turn filament of the left front park/turn lamp goes off.
• The left front marker lamp flashes off when the turn filament of the left front park/turn lamp goes on.
Voltage is applied to the right lamps in the same manner, when the right turn signal is turned on.
Hazard Lamps
Voltage is applied at all times through the following components to the normally open contact of the hazard switch in the turn/hazard-headlamp switch assembly:
• The STOP HAZ fuse
• The turn/hazard flasher
When the hazard switch is turned on, voltage is applied to the following components:
• The front turn lamps
• The rear turn lamps
The following lamps flash on and off:
• All of the turn lamps
• Both of the turn indicators
The front marker lamps flash with the hazard lamps on, just as the front marker lamps flash when the turn lamps are on. If the headlamp switch is in the OFF position, the front marker lamps flash on when the hazard lamps are on. The front marker lights will flash on when the hazard lamps are on if the headlamp switch is in one of the following positions:
When the hazard lamps are on, the following conditions apply:
• The turn circuit is always open.
• The turn/hazard flasher controls the lamp.
Park/Marker Lamps
Voltage is applied through the EXT LP fuse, to the headlamp switch at all times. Voltage is applied to the park lamps and the marker lamps when the headlamp switch is in the following positions:
The front marker lamps are grounded through the turn filament of the respective front park/turn lamp. The front marker lamps light as a result.
Stop Lamps
Voltage is applied through the STOP HAZ fuse to the brake switch at all times. When the brake pedal is depressed, the brake switch closes. This action applies voltage through the turn/hazard-headlamp switch assembly to the following lamps:
• The high mounted stop lamp assembly
• The left tail/stop-turn lamps
• The right tail/stop-turn lamps

Lexmark C510 995 Service Engine Error: I can turn All four toner cartridge gears, but they all seem to turn quite hard by hand. Is that my problem?

shut off power to printer. Pull your photoconducter unit out and check the position of the black marker located on the edge of the tranferbelt. I know one time I was fortunate enough to fix this error by rotating the photoconducter belt so that the marker was in a different position. Becareful not to touch the photoconducter belt (green shiny part) if at all posible. Reinstall the unit and power up.

2. If the above trick doesn't fix it after turning the printer off for a few minutes and you still get the same error when printing... You will have to replace the photoconducter unit. I wasn't as fortunate the second time I attempted the above trick and ended up having to order a new one. But hey its worth a try!!

ignition switch may be bad not cutting electricity to car when shut off. the way the ignition switch works, is that when car is shut off, there should be no electricity going through it. if in doubt or ya need help, go to any auto parts store and buy a haynes manual, they are based on a complete teardown of car for about 20.00, make sure you buy one for your make and model and year vehicle.also check main ignition fuse in fuse box.

C510 printer displays "994 Service Engine Error". How do you address this?

From a previous post: Posted by waynechurch on Apr 24, 2009 Is this error on a C510?, because the manual lists 994 as OPC belt marker sensor error.

Normally with an engine service error i reflash the engine firmware first, if that doesn't cure the fault i would then replace the engine board. If you need the firmware, visit the Lexmark site get the contact phone number for your region and ring them. They're normally quite helpful and of coarse can tell you how to reflash it.

I’m happy to assist further over the phone at

My gun wont stop shooting but the co2 tank is full what is wrong?

First make sure your marker has been fully cleaned out (No paint in the marker).

Always follow the flow of air when a problem like this arises.

Make sure their is nothing blocking the ASA (Where your tank screws into the gun)

If you have a regulator make sure you are not running any lower than 800 PSI, if you have a gas through grip then disregard this step.

First check your hammer o-ring, if it is broken you need to replace it and oil it, if not just oil it. This is the most common reason you would have this problem.

If you did not solve your problem yet than check your sear which holds back the hammer. If it is rounded then the bolt will skip instead of re-cocking the gun. Make sure it is still sharp, if this is your problem you can buy a new sear or file the one you have.

good luck!

These are poorly made and the laser burns out very quickly. They do not sell replacement parts, so it is a toss unit.
