ment parts charges incurred in providing the warranty service except where
purchaser abuse or other qualifying exceptions exist. The purchaser must

tion of instructions furnished by STANDARD HORIZON, nor does this war-
ranty extend to Products on which the serial number has been removed,

ERED UNDER THE TERMS OF THIS LIMITED WARRANTY.
