states may require the use of automatic fuel shut-off containers
to reduce fuel spillage.
After use
• DO NOT store a unit with fuel in its tank. Leaks can occur. Return unused fuel to an approved fuel storage
container.
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.
Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30) days, ninety (90) days when a
fuel stabilizer is added.
Stored two-stroke fuel may separate. ALWAYS shake fuel container thoroughly before each use.

minimum and assures a longer service life.
• Use bar and chain oil of high quality for this purpose.
• Do not use used or reclaimed oil to avoid various oiler
problems.
• Use high quality bar and chain oil.
• Use bar and chain oil of the following grades:
• SAE No. 30....in summer
