The speed rating printed on these reinforced wheels could range from 6000
to 6300 r/min. This is the minimum acceptable wheel speed rating for this
unit. Wheels rated less than 6000 r/min must not be used on this saw.
The wheel rotates at the same speed as the spindle (arbor) on which it is
mounted. The wheel must never be allowed to rotate faster than 6000 r/min
if the wheel speed is rated at 6000 r/min. (See "Engine Speed and Wheel
Speed", below.)
Since the reduction ratio of the engine drive pulley to the large driven pulley
is about 2 to 1, the wheel speed will be half whatever the engine drive pulley
speed is.
The unit has a governor system designed to govern the engine high speed,
at no load, to within 500 r/min of 10000 r/min, at which the wheel speed
should range between 4750 and 5250 r/min. – safety inside the 6000 r/min
limit. If the engine exceeds this speed limit, take it to your nearest ECHO
servicing dealer for service.
