THROTTLE LOCK--OUT
The
THROTTLE LOCK--OUT
must be
pressed before you can squeeze the
throttle trigger. This feature prevents you
from accidentally squeezing the trigger.
CHOKE/FAST IDLE LEVER
The choke and fast idle are set by pull-
ing the
CHOKE/FAST IDLE LEVER
out to
the full extent for cold starting or after
refueling. The choke provides additional
fuel to the engine during cold starting.
PRIMER BULB
The
PRIMER BULB
circulates fuel to the
carburetor to provide quicker starting.
CHAIN BRAKE
The
CHAIN BRAKE
is a device designed
to stop the chain if kickback occurs. The
chain brake activates automatically in
the event of kickback. The chain brake
activates manually if the front hand
guard is pushed forward. The chain
brake is disengaged by pulling the front
hand guard back toward the front handle
as far as possible.
CHAIN TENSION
It is normal for a new chain to stretch
during the first 15 minutes of operation.
You should check your chain tension
each time before you start the chain
saw. See
CHAIN TENSION
under the
MAINTENANCE
section.
WARNING:
If the saw is oper-
ated with a loose chain, the chain
could jump off the guide bar and result
in serious injury to the operator and/or
damage the chain making it unusable.
BEFORE STARTING ENGINE
WARNING:
Muffler is very hot
during and after use. Do not touch the
muffler or allow combustible material
such as dry grass or fuel to do so.
WARNING:
Be sure to read the
fuel handling information in the safety
rules section of this manual before you
begin. If you do not understand the
fuel handling information do not at-
tempt to fuel your unit. Seek help from
someone that does understand the in-
formation or call the customer assis-
tance help line at 1-800-235-5878.
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 overheat-
ing shown by smoke coming from the
chain and/or discoloration 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 Craftsman brand.
The oil output is automatically metered
during operation. Your saw will use
approximately one tank of bar oil for
every tank of fuel mix. Always fill the
bar oil tank when you fill the fuel tank.
FUELING ENGINE
WARNING:
Remove fuel cap
slowly when refueling.
IMPORTANT:
This equipment is de-
signed to operate on unleaded gasoline
with a minimum 87 octane (R+M/2
method), with ethanol blended up to
10% maximum by volume (E-10).
Before operation, gasoline must be
mixed with a good quality synthetic
2-cycle air-cooled engine oil designed to
be mixed at a ratio of 50:1. Craftsman
brand synthetic oil is recommended.
Mix gasoline and oil at a ratio of 50:1.
A 50:1 ratio is obtained by mixing
2.6 fluid ounces of oil with 1 gallon of
unleaded gasoline.
DO NOT USE
auto-
motive oil or marine oil. These oils will
cause engine damage. When mixing
fuel, follow instructions printed on con-
tainer. 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. Purchase
fuel in quantities that can be used within
30 days to assure fuel freshness.
CAUTION:
Never use straight gasoline
in your unit. This will cause permanent
engine damage and void the limited
warranty.
Do not use alternate fuels
such as ethanol blends above 10% by
volume (E-15, E-85) or any methanol
blended fuel. Use of these fuels can
cause major engine performance and
durability problems.
