Mixing Fuel/Filling With Fuel
WARNING!
Minimize the risk of fire,
burns, and personal injury!
n STOP engine before refueling.
n ALWAYS allow the engine to cool
before refueling!
n ALWAYS open the fuel cap slow-
ly to allow any pressure build-up
in the tank to release fuel vapor
slowly.
n Avoid overfilling and wipe up all
spilled fuel. Move the engine at
least 3 meters from the fueling
point, storage area and other
readily flammable
materials before restarting!
n ALWAYS inspect the unit for fuel
leaks before each use. During
each refill, make sure there are
no fuel leaks around the fuel cap
and/or tank. If a fuel leak is evi-
dent, stop using the unit immedi-
ately. Fuel leaks must be repaired
before using the unit.
n NEVER smoke or light any fires
near the engine or fuel source!
n NEVER place any flammable
material near the engine muffler!
n NEVER operate the engine with-
out the muffler in good working
condition.
Bar Oil / Filling With Oil
Oil Requirements
n When available, use Shindaiwa Pre-
mium bar and chain oil.
n When Shindaiwa oil is not available,
use a premium 30-weight oil spe-
cifically blended for bar and chain
lubrication.
n For cold weather operation, bar oil
may be thinned by mixing with clean
kerosene at a ratio of 1:1.
Filling the Oil Reservoir
n Place the saw on its side (clutch
cover down), and wipe any chips or
debris from around the oil cap.
n Remove the oil cap at the front of the
saw.
n Fill the oil reservoir with bar and
chain oil and replace the cap.
n Wipe spilled oil from handles and
controls before starting the saw.

IMPORTANT!
Shindaiwa high-performance 2-cycle
engines are designed to operate on a
50:1 mixture of unleaded gasoline and
2-cycle mixing oil. Using a fuel mixture
less than 50:1 ratio (such as 80:1 or
100:1) can cause catastrophic engine
failure!
1. Use only fresh, clean unleaded gaso-
line with a pump octane rating of 87
or higher.
2. Mix fuel with a 2-cycle mixing oil
designed for use in high-performance
2-cycle air-cooled engines.
CAUTION!
n Some types of gasoline contain
alcohol. Never use any type of
gasoline containing more than
10% alcohol by volume! More
than 10% alcohol by volume may
affect the lubricating qualities
of 2-cycle mixing oils reducing
engine life and/or causing engine
failure.
n Generic mixing oil and marine
engine oil may not be intended
for use in high-performance 2-
cycle engines and should never
be used in Shindaiwa engines.
Mixing oils not intended for use in
high-performance air-cooled 2-cy-
cle engines can cause excessive
carbon deposits, reduce engine
life and/or cause engine failure.
CAUTION!
Proper lubrication is critical to the
performance and service life of your
saw's oil pump, guide bar, and saw
chain! Always use a high quality
lubricating oil designed for saw
chain lubrication! Never use dirty or
reclaimed oil!
Oil Pump Adjustment
Guide bar and saw chain lubrication
is automatically provided by an adjust-
able-rate oil pump designed to operate
whenever the clutch drum rotates. A
temporary increase in oil flow rate is
often desirable when cutting hardwoods
or large-diameter softwoods, and can be
provided as follows:
1. Stop the engine and verify that the
engine stop switch is in the "OFF"
position.
Gasoline 2-cycle mixing oil
liters milliliters
2.5 l .............................. 50 ml
5 l ................................100 ml
10 l ..............................200 ml
20 l ..............................400 ml
3. Place the saw on a hard surface with
the fuel cap up and wipe any chips or
debris from around the fuel cap.
4. Remove the fuel cap and fill the tank
with clean, fresh 2-cycle fuel mix.
Avoid overfilling and fuel spillage.
5. Wipe any spilled fuel and move the
saw at least 3 meters from the fueling
point before starting the engine.
2. Place the saw on its side, with the
clutch cover facing up.

to Increase Oil Flow
3. Use a screwdriver to push down and
turn the oil flow rate adjustment
screw.

lubrication.
