Spilled fuel is a leading cause of hydrocarbon emissions. Some 
states may require the use of automatic fuel shut-off containers to 
reduce fuel spillage.
Storage - Fuel storage laws vary by locality. Contact your local government 
for the laws affecting your area. As a precaution, store fuel in an approved, 
airtight container. Store in a well-ventilated, unoccupied building, away from 
sparks and flames.
• Empty the fuel tank prior to storing the unit. Return unused fuel to an 
approved fuel storage container.
Stored fuel ages. Do not mix more fuel than you expect to use in 30 
days, 90 days when a fuel stabilizer is added.
Stored two-stroke fuel may separate. ALWAYS shake fuel container 
thoroughly before each use.
Used oil and gasoline, and soiled towels are hazardous waste 
materials. Disposal laws vary by locality.
