Operate this unit only
in a well-ventilated
outdoor area. Carbon

Never operate the saw
without the bar and
chain properly
installed.
WARNING:
WARNING: Be sure to read the Oil and Fuel Information
Section of this manual before you begin. If you do not
understand the oil and fuel information, do not attempt
to fuel your unit. For more information contact your
local Sears service center at 1-800-4-MY-
HOME®.
GUIDE BAR AND CHAIN OIL
The bar and chain require lubrication. The chain oiler
provides continuous lubrication to the chain and guide
bar. Be sure to fill the bar oil tank when you fill the fuel
tank. (Capacity = 6.8 fl. oz.). Lack of oil will quickly
ruin the bar and chain. Too little oil will cause over-
heating with smoke coming from the chain and discol-
oration of the bar. For maximum guide bar and chain
life, we recommend you use Craftsman chain saw bar
oil. If Craftsman bar oil is not available, you may use a
good grade SAE 30 oil until you are able to obtain the
Craftsman brand. The oil output is automatically
metered during operation. Your saw will use approxi-
mately one tank of bar oil for every tank of fuel mix.
Always fill the bar oil tank when you fill the fuel tank.
FUELING THE ENGINE
WARNING: Remove fuel cap slowly when refueling.
This engine is certified to operate on unleaded gaso-
line. 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. 40:1 ratio is
obtained by mixing 3.2 ounces of oil with 1 gallon of
unleaded gasoline. Included with this saw is a 3.2
ounce container of oil. Pour the entire contents of this
container into one gallon of gasoline to achieve the
proper fuel mixture. DO NOT use automotive oil or
boat oil. These oils will cause engine damage. When
mixing fuel, follow the instructions printed on the oil
container. Once oil is added to the gasoline, shake
container momentarily to assure that the fuel is thor-
oughly mixed. Always read and follow the safety rules
relating to fuel before fueling your unit.
BEFORE STARTING ENGINE
IMPORTANT:
Experience indicates that alcohol blended with fuels
(called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and forma-
tion of acids during storage. Acidic gas can damage
the fuel system of an engine when in storage. To avoid
engine problems, the fuel system should be emptied
before storage for 30 days or longer. Drain the gas
tank, start the engine and let it run until fuel lines and
carburetor are empty. Use fresh fuel next season.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage can occur. See STOR-
AGE instructions for additional information.
CHAIN BRAKE
Be sure the chain brake is disengaged by pulling the
front hand guard back toward the front handle as far
as possible. The chain brake must be disengaged
before cutting with the saw.
WARNING: The chain brake must not move when the
engine runs at idle speed. If the chain brake moves at
idle speed, refer to CARBURETOR ADJUSTMENT in
this manual. Avoid contact with the muffler. A hot muf-
fler can cause serious burns.
IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the full
extent of the rope as this can cause the rope to break.
Do not let starter rope snap back. Hold the handle and
let the rope rewind slowly. For cold weather starting,
start the unit at FULL CHOKE; allow the engine to
warm up before squeezing the throttle trigger.
DO NOT attempt to cut material with the choke/fast idle
lever in the FULL CHOKE position.
