Load Compensation

automatically compensates for changes in motor speed when

the chair drives over loads such as sidewalks, curbs or slopes. Correct Load

Compensation is important for all chairs to reach acceptable performance,

especially when a chair has switched controls, for example a scanner or Sip and Puff.
