Wheel Speed
Prim Use
The speed rating printed on these reinforced wheels could range from 4000
to 4400 r/min. This is the minimum acceptable wheel speed rating for this
unit. Wheels rated less than 4400 r/min must not be used on this cutter.
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 4400 r/min
if the wheel speed is rated at 4400 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 2.3 to 1.
The unit has a governor system designed to govern the engine high speed,
at no load, to within 500 r/min of 9500 r/min, at which the wheel speed
should range between 3930 and 4370 r/min. – safety inside the 4400 r/min
limit. If the engine exceeds this speed limit, take it to your nearest HITACHI
servicing dealer for service.
