PRE-OPERATION INSPECTION
Perform the following steps before every use of the machine:
Check fuel mixture level
·
Check bar lubrication
·
Check chain sharpness
·
NOTE: Chain sharpening is a complicated task that
requires special tools. We recommend that you refer
chain sharpening to a professional chain sharpener.
Check chain tension
·
Inspect and clean the guide bar
·
Check for damaged parts
·
Check for loose caps
·
Check for loose fasteners
·
Check for loose parts
·
Check for fuel and oil leaks
·
NOTE: It is normal for a small amount of oil to appear
under the saw after the engine stops. Do not confuse this
with a leaking oil tank.
FUELING THE ENGINE
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 attempt to fuel your unit. Seek help from
someone that does understand the information
or call the consumer assistance help line.
WARNING! Remove the fuel cap slowly when
fueling.
This equipment is designed 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
full synthetic 2-cycle air-cooled engine oil designed to be
mixed at a ratio of 50:1.
A 50:1 ratio is obtained by mixing 2.6 fluid ounces of full
synthetic oil with 1 gallon of unleaded gasoline. DO NOT USE
automotive oil or marine oil. These oils will cause engine
damage.
When mixing fuel, follow the instructions printed on the
container. Once the oil is added to the gasoline, shake the
container momentarily to assure that the fuel is thoroughly
mixed.

STARTING AND STOPPING
7
15. Hold up the bar tip and tighten the bar nuts with the
combination tool.
When fitting a new chain, the chain tension has to be checked
frequently until the chain is run-in. Check the chain tension
regularly. A correctly tensioned chain ensures good cutting
performance and long life.
Fill the fuel tank completely with properly mixed fuel.
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.
During storage of your fuel mixture,
the oil will separate from the
gasoline.
Shake the fuel can weekly to insure
proper blending of the gasoline and
oil.
CAUTION: Never use unmixed gasoline in your unit. This
will cause permanent engine damage and void the limited
warranty.
CAUTION: 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 problems and void the limited
warranty.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubrication. Lubrication
is provided by the automatic oiler system when the oil tank is
kept filled. Lack of oil will quickly ruin the bar and chain. Too
little oil will cause overheating shown by smoke coming from
the chain and/or discoloration of the bar. In freezing weather
oil will thicken, making it necessary to thin bar and chain oil
with a small amount (5 to 10%) of #1 diesel fuel or kerosene.
Bar and chain oil must be free flowing for the oil system to
pump enough oil for adequate lubrication.
If bar and chain oil is not available, use a good grade SAE 30
oil.
Fill the oil tank completely with oil.
CAUTION: Never use waste oil for bar and chain
lubrication.
CAUTION: Always stop the engine before removing the
oil cap.
