Yanmar Diesel

48 HP (35 kW)

This equipment has been tested for EMC using the methods outlined in EN14982:98. The tests found that

the equipment did not exceed the radiated emission limits. The saw was tested in a semi-anechoic chamber at

NCEE, Lincoln, Nebraska, a FCC registered laboratory. The test report is on file at Husqvarna Construction Products,

Olathe, Kansas.

This equipment has been tested for HAV in accordance with ISO 5349. The results are shown in the following chart.

FS 4800 D

The Aeq value is the measured continuous vibration at the extended handlebars expressed as acceleration with the

units of m/s

(meters per second squared). The measured values were taken with a fully warmed engine, running at

maximum rated RPM. 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

as defined in Directive 2002/44/EC of 25 June 2002.

The time weighted daily vibration exposure time can be found with the following formula:

Normal operation of this equipment does not require the continuous contact of the hand to the handlebar. Observation

of professional cutters using this saw has shown that the majority of operators actually hold the handle bars less than

25% of the cutting time.

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 fingers, hand or wrists.
