* NOTE: Operating at the continuous power rating for periods of up to 4 hours is acceptable.  However, operating for extended periods at high temperatures will result in premature component and bearing failure. Limiting the length of the cycle and the component temperatures will guard against premature failure. Where continuous duty is desired for longer time intervals, component temperatures should be maintained less than 100°C; monitoring the outside brake surface temperature is a sufficient reference.


¹
 Model HD-510, HD-515, HD-800 and HD-805 Dynamometers require air cooling provided by user. Regulator and filter package is provided as standard equipment on these units. See catalog for pressure ratings.
²  Blower package is included as standard equipment with Model HD-710, HD-715, HD-810, HD-815 and HD-825 Dynamometers.

The maximum speed will depend on what type of keyway (if any) is used on the shaft. Unless specified, the dynamometer shaft will be made without a keyway.
