5.
While holding up the tip of the bar, adjust the chain tension
by turning the tensioner screw until the tie straps just touch the
bottom side of the bar rail.
6.
Tighten the nuts securely with the bar tip held up
(12~15N.m). Then check the chain for smooth rotation and
proper tension while moving it by hand . If necessary, readjust
with the chain cover loose.
7.
Tighten the tensioner screw.
Note: A new chain will expand is length in the beginning of use. Check and readjust the
tension frequently as a loose chain can easily derail or cause rapid wear of itself and the
guide bar.
4. Fuel and Chain Oil
FUEL
WARNING
Gasoline is very flammable. Avoid smoking or
bringing any flame or sparks near fuel. Make
sure to stop the engine and allow it cool
before refueling the unit. Select outdoor bare
ground for fueling and move at least 3 m (10 ft)
away from the fueling point before starting the
engine.
Use an anti-oxidant added quality oil expressly
labeled tor air-cooled 2-cycle engine use (JASO
FC GRADE OIL or ISO EGC GRADE).
Do not use BIA or TCW(2-stroke water-cooling
type)mixed oil.
RECOMMENDED MIXING RATIO
GASOLINE 35 : OIL 1
Exhaust emission are controlled by the fund-
amental engine parameters and components
(eq ., carburetion, ignition timing and port
timing) without addition of any major hard-
ware or the introduction of an inert material
during combustion.
These engines are certified to operate on
unleaded gasoline.
Make sure to use gasoline with a minimum octane
number of 89RON.
If you use a gasoline of a lower octane value than
prescribed. There is a danger that the engine
temperature may rise and an engine problem
such as piston seizing may cones- quaintly occur.
Unleaded gasoline is recommended to reduce the
contamination of the air for the sake of your health
and the environment.
Poor quality gasoline or oils may damage sealing
rings, fuel lines or fuel tank of the engine.
HOW TO MIX FUEL
Pay attention to agitation
1.
Measure out the quantities of gasoline and oil
to be mixed .
2.
Put some of the gasoline into a clean,
approved fuel container.
3.
Pour in all of the oil and agitate well.
4.
Pour in the rest of gasoline and agitate again
for at least one minute. As some oils may be
difficult to agitate depending on oil ingredients,
sufficient agitation is necessary for the engine
to last long. Be careful that, if the agitation is
insufficient, there is an increased danger of
early piston seizing due to abnormally lean
