Oil Recommendations
Using the proper type and weight of oil in the
crankcase is extremely important. So is checking oil
daily and changing oil regularly. Failure to use the
correct oil, or using dirty oil, causes premature engine
wear and failure.
Oil Type
Use high quality detergent oil of APl (American
Petroleum Institute) service class SG, SH, SJ or
higher. Select the viscosity based on the air
temperature at the time of operation as shown in the
following table.
A logo or symbol on oil containers identifies the API
service class and SAE viscosity grade. See Figure 3.
Figure 3. Oil Container Logo.
RECOMMENDED SAE VISCOSITY GRADES
Refer to "Maintenance Instructions" beginning on
page 8 for detailed oil check, oil change, and oil
filter change procedures.
Fuel Recommendations
TEMPER_,TURE RANGE EXPECTED BEFORE NEXT OIL CI IANGE
*Use of synthetic oil having 5W-20 or 5W-30 rating is acceptable,
up to 4°C (40°F).
**Synthetic oils will provide better starting in extreme cold below
-23°C (-10°F).
Figure 2. Viscosity Grades Table.
NOTE:
Using other than service class SG, SH, SJ or
higher oil or extending oil change intervals
longer than recommended can cause engine
damage.
NOTE:
Synthetic oils meeting the listed classifications
may be used with oil changes performed at
the recommended intervals. However to allow
piston rings to properly seat, a new or rebuilt
engine should be operated for at least 50
hours using standard petroleum based oil
before switching to synthetic oil.
WARNING: Explosive Fuel!
Gasoline is extremely flammable and its vapors can
explode if ignited. Store gasofine only in approved
containers, in well ventilated, unoccupied buildings,
away from sparks or flames. Do not fill the fuel tank
while the engine is hot or running, since spilled fuel
could ignite if it comes in contact with hot parts or
sparks from ignition. Do not start the engine near
spilled fuel. Never use gasoline as a cleaning agent.
General Recommendations
Purchase gasoline in small quantities and store in
clean, approved containers. A container with a capacity
of 2 gallons or less with a pouring spout is
recommended. Such a container is easier to handle
and helps eliminate spillage during refueling.
Do not use gasoline left over from the previous season,
to minimize gum deposits in your fuel system and to
ensure easy starting.
