I notice a “NEW” saw listed at Makita Canada: Model No: EA5600FREE 55.6 cc Environment-Friendly 2-Stroke Chainsaw with Easy Start and Winter Operation Mode https://www.makita.ca/index2.php?event=tool&id=3203&catid=7 Displacement 55.6 cc (3.4 cu.in.) Chain Pitch / Gauge 3/8" / .058" Max. Engine Speed 13,800 RPM Power Rating 3.0 kW / 3.9 H.P. Vibration Level 5.5 m/s2 Noise Level 104.4 dB(A) Fuel Tank Capacity 570 ml Oil Tank Capacity 320 ml Fuel / Oil Mixture 50:1 Net Weight Dry w/o Bar/Chain 12.8 lbs (5.8kg) I'm a little puzzled why this “NEW” 55.6cc saw has the same HP (3.9) as the Dolmar 50CC PS-5105H? PS-5105 H Displacement 50 cc (3.1 cu. in) Power rating 2.8 kW (3.9 HP) Net weight 5.6 kg (12.3 lbs) http://www.dolmarpowerproducts.com/productcatalog/chain_saws_gasoline/ps-5105_h/index.html Is the Dolmar website obsolete? I like the idea of a strong 55cc version but couldn't they squeeze a bit more horse power out of it to offset the added weight?
