BEFORE STARTING ENGINE
_WARNING: Be sure to read
the fuel information in the safety rules
before you begin. If you do not
understand the safety rules, do not
attempt to fuel your unit. Call
1-800-235-5878.
FUELING ENGINE
_WARNING: Remove fuel cap
slowly when refueling.
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good
quality synthetic 2-cycle air-cooled
engine oil. We recommend
Craftsman <=>brand synthetic oil. Mix
gasoline and oil at a ratio of 40:1. A
40:1 ratio is obtained by mixing 3.2
ounces of oil with 1 gallon of unleaded
gasoline. Included with this trimmer is
a 3.2 ounce container of oil. Pour the
entire contents of this container into 1
gallon of gasoline to achieve the
proper fuel mixture. DO NOT USE
automotive oil or marine oil. These oils
will cause engine damage. When
mixing fuel, follow instructions printed
on container.
Once oil is added to gasoline, shake
container momentarily to assure that
the fuel is thoroughly mixed. Always
read and follow the safety rules
relating to fuel before fueling your unit.
