My hitachi 2nd fix nailer isn't charging, I put the batteries on charge and after about 2mins the light turns off and they stop charging. How can I fix this. Cheers

Test the volts and amps of the battery after charging, then try to shoot nails then test again after the blinking orange light. Battery is failing, they only have a certain number of recharge cycles and are also governed by age degradation.

Take it back, fool with and you loose the warranty.

Please have your battery tested Matthew at the following link. Batteries Plus Bulbs and Battery Store Find Battery for laptop auto cell...

First thing is , when did You clean it last?

generally when charging the light will be red until a full charge is indicated and the light will turn green. if while trying to charge the light remains green I would try reinserting the battery or charging unit. If still the same you might have a problem with either.

check your battery with a volt meter, also your charger may be bad

Start with the basics:
First check that the butane (or whatever gas is used) canister is full. If empty, put in a new one.

Second check to make sure your battery is fully charged to be able to fire the spark to work the nail gun. If not get the battery charged and/or replaced as needed.

Third make sure all of the safeties are working properly and that you have them engaged to the piece of wood you are nailing when you try the trigger.

If beyond that it does not work it could be a bad trigger, a bad safety switch, or even a bad connection from the battery to the device.

Does it seems like the new battery takes a charge? If not, then as good as Hitachi's are...it sounds like a defective battery to me. Should be able to warranty for you no prob.

If you have a buddy, check it in his charger. Or possibly try a charger in the store if they have a demo.

Does the fan run and the light blink ont he nailer? I have one that I just bought. I put in the wrong type of nails and got one stuck. I had to take the front apart to clear it and now the damm thing wont fire. The green light blinks and the gas cartridge is basically full, even the fan does run after I release the push lever, but no fire???

I wonder if yours is the same as mine did fire for a couple nails first just fine then got jammed...

I will try to charge the battery more.... MAybe like yours it needs a strong charge for the spark...
