ECHO have released a new issue of their hand-arm vibration report, based on comprehensive tests of the full range of ECHO power tools. The report clearly shows the vibration levels measured on each tool with a low frequency weighting filter applied (as specified in the British Standards) which quantifies the relative importance of different frequencies and corresponds to the way vibration is imparted into the hands and causes damage.
The tests were conducted by the Industrial Noise and Vibration Centre Ltd. under laboratory conditions, and were made in three orthogonal directions using an accelerometer attached directly to the handle of the products, as close as possible to the operator's hand.
The measured vibration for each tool in all three directions is presented in the report. The frequency weighted RMS vibration ah,w is representative of continuous ("finger on trigger") tool operation.
The daily usage limit presented in the report for single tool operation is based on not exceeding a vector sum action level of 2.5m/s² - 5m/s² in an 8 hour day, with no other exposure to high vibration.
Results of the tests have highlighted a number of ECHO products which have particularly low vibration levels. These include the new HCR-161ES Hedgecutter with a vibration figure of just 2.6m/s² and the new SRM-265ESU brushcutter with a vibration figure of just 1.9m/s².
The HCR-161ES hedgecutter features a new emission-compliant 21.2CC two-stroke engine which is fully spring-mounted, designed to create lowest possible vibration levels. The HCR-161ES is equipped with a double-sided 62cm bar, weighs just 5.5kg, and is fitted with a fully revolving back handle, to provide the user with incredible flexibility.
The new SRM-265ES brushcutter is fitted with a 25.4cc engine, featuring ECHO i-Start, an innovation in instant starting which makes the first time starting of 2-stroke engines a certainty, while removing 90% of the effort required.
The overall length of 1790mm allows safe and comfortable operation, the design of the new SRM-265ES ensuring perfect balance for maximum cutting area with minimum effort.
