Makita says its new DUC353Z Twin 18v brushless motor chainsaw matches the logging performance of similar sized petrol-powered saws.
The saw’s motor has a rated output of 1,100 watts, similar to a 32cc petrol machine, and comes fitted with an identical 35cm-long bar and a chain speed of 20 metres per second. Trials have shown that two fully charged 5.0Ah batteries will deliver over 60 cuts through five-inch diameter timber, at least seven linear metres of cutting per charge.
This back-handle saw weighs 5.2kg ready to operate with an ergonomic soft-grip handle; variable speed trigger and constant speed control; automatic electric chain brake on trigger release, with kickback brake protection and lock-off lever.
The 200ml chain oil tank has adjustable flow through the pump with metal gears to the automatic chain lube system and has a capacity display window. The tool-less chain tensioning and adjustment system is included, while the strong metal spike bumper allows easier cutting. The chain catcher can be removed for machine servicing.
In addition to the drive brake safety systems the main power system is automatically turned off if the operator does not grip the lock-off lever 10 seconds after the machine is switched on. The same happens if the operator does not squeeze the trigger switch within one minute after switch-on, even if the lock-off lever is gripped.
