My panasonic 28.8v sds has started to have a burning smell and smokes

the bad smell you refer to is a smell of the electric motor burned out have the motor replaced the machine should be ok

Blue smoke (how many miles on engine, 50k or 500K???????
to some this means, burning oil, others steam
it that blue smoke lingers a long time that is oil burning
and smells just like oil burning.
and means 2 things,
1: engine burns oil.
2: if car had autotmatic trans the vacuum modulator love fail
and suck ATF fluid to the intake plenum and burn it, and bingo burning oil like mad.
3: PCV valve packed solid,and forces engine to leak oil or burn oil. or both. this is a 50k miles service point, skipping this?
4: gas in the oil making it thin and not sneaks past valve stems.
does oil change cure this.>?

now engines.
worn out engines smoke. (burn oil)
as do bad valve guides and seals.
and bad piston rings.
100 years same story, and miles matter. History on engine too.
matters.

no year, ?

try a new spark plug e and then if wires to spark plug , replace that too. and cap and rotor if it has that....?????



then when spark is good, check compression with any $20 gauge.

no year, i give up.

1976 accord? surely ive no clue.



smoke has 3 colors, (my rules not ASE)

1 black fuel (flooding etc) can seem gray but is black .

2: white and lingers., oil burning , bad. news.

3: white and fades fast, is STEAM, like moms tea pot, look next time..

smell white smoke, smells sweet, its toxic antifreeze.

smells like oil dripped on an hot exhaust? that is the smell of oil burning



smoke where, under front of car, or at the end of the tail pipe. ?????????????



how you like my smoke rules, even mom can figure it out.

Be grateful it didn't burn the house down.
Replace it.
Cost of parts will outweigh cost of replacement.

You don't mention what that smell is reminiscent of?

You don't mention the colour of the "smoke" and you didn't say whether the engine is petrol or diesel?

You don't mention whether the road behaviour/performance is normal?

White smoke is almost always steam or in the case of a diesel it could be an unburned fuel mist, grey/black is excess fuel and blue or grey/blue is burning oil.

Some steam is fairly normal until the engine and exhaust system is hot but excessive amounts could be one symptom of head gasket trouble. If the engine is drinking coolant and sending it through the exhaust as steam it will sometimes smell spicy.

Burning oil smells a bit like burned eggs in the frying pan.

If the car hasn't ultra-low sulphur oil and fuel the catalytic converter will convert sulphur traces into hydrogen sulphide - the bad egg gas...

Get the filter housing out of the machine and wash it out. Blow out the blowers housing. Change the control thermostat.It mounts right next to the fuse on the back:

It is not unusual for an older truck to be burning a little oil. It is burning very little so you will not smell burnt oil or see blue smoke in the exhaust. But the oil burn does add up and you may notice a drop on the oil dipstick after a few weeks. On a 9 year old truck under normal working conditions will burn a little oil. If you are having to add 1 liter between oil changes, that is ok, just shows normal engine ware. 2 Liters is acceptable between oil changes if the truck does a lot of heavy pulling or work. 3 or more liters indecates a problem, but at that rate, you should be able to smell oil and see blue smoke.

In most cases, this is a problem with the inverter or a bad transfotmer.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer. You can find one here:

Replace the belt. It is probably stretched and is slipping. This will produce the smell your describing. These belts should be changed at least once a year.
