EMC
(ElectroMagnetic Compatibility)
The Honda engine on this equipment has been tested for EMC using the methods outlined in EN 14982:98. The tests
found that the engine did not exceed the radiated emission limits. This test report is on le at Husqvarna Construction
Products, Olathe, Kansas, USA. Because the engine is the source for a vast majority of Electromagnetic activity of
this machine, Husqvarna Construction Products declares the entire machine to be Electromagnetically Compatible.
Technical Data - Sound Level, EMC, and HAV
HAV
(Hand-Arm Vibration)
This tool does not exceed the exposure action value of 2.5 m/s
2
.
This equipment has been tested for HAV in accordance with ISO 5349. The results are shown in the following chart.
Model Maximum Vibration (Aeq) in m/s

Maximum Exposure Time

FS520
0.89 +100%
FS524
1.46 +100%
The Aeq value is the measured continuous vibration at the extended handlebars expressed as acceleration with the
units of m/s
2
(meters per second squared). The measured values were taken with a fully warmed engine, running
at maximum rated RPM and a 600-mm blade. The measurement point was the grip of the extended handlebars.
Instrumentation was a Larson Davis model HVM100 Human Vibration Meter and the SEN021 Triaxial Accelerometer.
The accelerometer was secured to a hand adapter, which allows it to sense the same magnitude of vibration as the
operator’s hand.
The Maximum Exposure Time is a calculated value referenced to an 8-hour workday and the “daily exposure action
value” of 2.5 m/s
2
as dened in Directive 2002/44/EC of 25 June 2002.
The time weighted daily vibration exposure time can be found with the following formula:
Maximum Exposure Time = (2.5/Aeq)
2
X 8 hours
Over exposure to vibrations can result in blood vessel or nerve injury to persons suffering with blood circulation problems.
Seek medical attention if you experience physical symptoms that can be related to over exposure to vibrations. Examples
of symptoms are numbness, lack of feeling, tingling, tickling, pain or a reduction of normal strength, or changes in skin
color. These symptoms normally appear in the ngers, hand or wrists.
