Dolmar RS7900 Unlimited
« on: April 11, 2017, 02:01:18 pm »
I need to pull this from a thread here and save it in its own thread.

Dolmar RS 7900 had the unlimited coil overseas.

   

    "Collector's item: Special limited edition of DOLMAR's PS-7900 RS professional chainsaw.
    Lovers of technical rarities will have to hurry if they want to be one of the 300 proud owners worldwide of the DOLMAR PS-7900 RS professional chainsaw.

    The renowned Hamburg-based power equipment manufacturer is about to bring out a limited edition of its best-selling professional chainsaw model. Only 300 will be built, distinguished from the standard model by its unique design and performance tuning for optimum power delivery.

    The limited edition model is instantly recognizable by the special black trim applied to the area below the air filter cover. The top handle and exhaust are likewise finished entirely in black. The power output of the DOLMAR PS-7900 RS professional chainsaw has been boosted by an additional 0.1 kw to 4.7 kw – giving it an industry-beating power-to-weight ratio of just 1.34 kg/kw. Its advanced cylinder/piston configuration delivers maximum levels of torque and power.

    Thanks to its advanced cylinder/piston configuration the power output of the limited-edition PS-7900 RS
    (Racing Sport) has been boosted by 0.1 kw over the standard model to 4.7 kw
    (6.4 hp). Torque delivery – crucial for efficiency of cutting – is improved across the entire speed range compared with the standard model. And since these performance gains have been achieved without adding to the weight of the machine, the Dolmar PS-7900 RS boasts an industry-beating power-to-weight ratio of just 1.34 kg/kw – or 0.98 kg per hp.

    A direct comparison between the power and torque curves for the PS-7900 RS, as measured in the test laboratory, and those of rival products in the same weight category demonstrates how far advanced Dolmar’s motor technology really is compared with the technology of competitors. Both the PS-7900 RS and the PS-7900 produce on average up to 16% more power and torque across the entire speed range than rival products. In automotive terms, the combination of superior power delivery and low weight makes the Dolmar PS-7900 RS a thoroughbred sports car among chainsaws.

    Production is limited to just 300 units worldwide. Each saw is individually numbered from 1/300 to 300/300 and is supplied with its own certificate of authenticity. And exclusivity is guaranteed. The special elements that make the DOLMAR PS-7900 RS unique are not available for retrofitting, so there is no way for tuning enthusiasts to “clone” the PS-7900 RS.

    What’s more, the very first limited-edition model to come off the production line – Number 1/300 – will not be available to any buyer at any price. It will be awarded instead to the winner of the 2003 national German Forestry Workers' Championships."

Is there a part number?  Has anyone tried to get 1 from overseas sellers?  Some of these have to be salvage by now.

As far as part numbers for the black coil , all that I've found is this from the 7900 ipl :
Page 4 ,item # 183 ,p/n 010 038 141 .  It's apparently for the coil AND the flywheel as an assembly . Begs the question what the difference is in the flywheel .

I have been believing mine to be unlimited, but a IPL in my hand shows its number as #114, wonder if this IPL is an older edition?
