Is it feasible to cram a chainsaw full of highly advanced engine technology such as X-Torq® and AutoTune™, increase output by 10-15 % – and still lose weight? The answer is yes. Our new 500 series of chainsaws proves exactly this.
When we started our concept study, the aim was to create the optimum saw, with maximum power and minimum weight. We broke the chainsaw down into the very smallest detail, and scrutinised the 200 constituent parts. Each sub-system was analysed in minute detail, including the screw lengths in order to keep the overall weight down.
We managed to slim down the entire rotating system including the crankshaft and flywheel by 1-2 hectograms. We developed a new starting spring that weighs 30 grams less than a traditional spring – but with the same force. And we achieved the same weight gain by designing a new, thinner clutch drum. Moreover, by tilting the cylinder backwards the saw body was made lower and sleeker.
The end result...
Take the 560 XP® model – even though it is packed with new technology that is quite weighty – is around two hectograms lighter than its predecessor the 357 XP®. In fact, we improved the power-to-weight ratio with 15 %. We like to say that we created a 60-cc saw that is as powerful as a 70-cc and as handy as a 50-cc.
