This product is equipped with a catalytic converter in the exhaust system to significantly reduce
exhaust emissions. The catalytic converter converts carbon
monoxide and hydrocarbons into harmless carbon dioxide and
water.
The catalytic converter requires special care.
• Use only unleaded gasoline. Never use leaded gasoline.
Leaded gasoline significantly reduces the capability of the
catalytic converter.
• Do not use 2-cycle oil that contains Phosporus (P), Lead
(Pb), or Sulfur (S). These elements will reduce the life and
performance of the catalytic converter.
