Komatsu Zenoah BCZ4500CL

This is Komatsu Zenoah's Strato Charged engine. It's lean on fuel and clean on emissions. There's power to spare and it's there when you need it. In that respect this is a top performer and a very professional machine. It's one that you should also give you plenty of miles to the gallon.

However, you may want to use another harness with this saw. The one supplied lets the machine down. “The balance is fine, but there is vibration coming through the harness and up the back of my head. It’s enough to make your teeth chatter,” says our tester. “There’s not sufficient padding on the harness — there’s nothing to absorb shock — and the harness is pulling into my ribs.”
The BCZ4500CL is fitted with Super E-start. This easy-start mechanism is designed so that less pulling force is needed to fire-up the engine. And yes, less pulling force is needed to extend the pull chord but — typical of a test day — the ignition is taking a break. Check the fuel. Check the “on” switch. Check the choke. All fine. Eventually, and without explanation, the engine is revving.
There are many good design features on this model — heavy-duty gearcase, easy-to-adjust handles, easy-to-use controls. At 9kg it is the heaviest in the test, but it is well constructed. For the price it’s a good machine — but you will probably want to buy another harness.
