The Environmental Protection Agency (EPA), and Bad Boy Inc. are pleased to explain the evaporative emission control system’s warranty 
on your 2017 equipment. New equipment that uses spark ignition engines for off-road use must be meet stringent anti-smog standards. 
The evaporative emission control system on your equipment is designed, built, and equipped so it conforms at the time of sale to the 
ultimate purchaser with the requirements of 40 CFR 1060. The evaporative emission control system is free from defects in materials and 
workmanship that may keep it from meeting said requirements. Bad Boy Inc. must warrant the evaporative emission control system on 
your equipment for two years provided there has been no abuse, neglect or improper maintenance. If an evaporative emission control

first two years Bad Boy Inc. will replace the defective component. Your evaporative emission control system may include parts such as 
fuel tanks, fuel lines, carbon canisters, fuel caps, valves, vapor hoses, clamps, or connectors.
