Shindaiwa 502s - Manual (Page 9)

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!
NEVER
smoke or light fires near the
engine.
ALWAYS stop the engine and allow it
to cool before refueling.
ALWAYS open the fuel cap slowly
to allow any pressure build-up in the
tank to release fuel vapor slowly.
ALWAYS wipe all spilled fuel and move
at least 3 meters from the fueling point
and source before starting.
ALWAYS inspect the unit for fuel
leaks before each use. During each
refill, check that no fuel leaks from
around the fuel cap and/or fuel tank.
If fuel leaks are evident, stop using
the unit immediately. Fuel leaks must
be repaired before using the unit.
ALWAYS move the unit at least 3
meters away from a fuel storage area
or other readily flammable materials
before starting the engine.
NEVER
place flammable material
close to the engine muffler.
NEVER operate the engine without
the muffler and spark arrester screen
in place.
ALWAYS
have fire extinguishingtools
available if you should need them.
Sparks can come from the muffler, the
bar and chain or other sources. Help
prevent forest fires.
Mixing fuel
Place the unit on a flat surface with the 1.
fuel cap up.
Clear any chips or other debris from
2.
around the fuel filler cap.
Remove the fuel cap and fill the tank
3.
with clean, fresh 2-cycle fuel mix. Avoid
overfilling and fuel spillage.
Wipe any spilled fuel and move the saw
4.
at least 10 feet (3 meters) from the fuel-
ing point before starting the engine.
Filling the fuel tank
CAUTION!
This engine is designed to operate on
a 50:1 mixture consisting of unleaded
gasoline and ISO-L-EGD or JASO FC
class 2-cycle mixing oil only. Use of
non-approved mixing oils can lead to
excessive carbon deposits. CAUTION!
Never use any type of gasoline con-
■
taining more than 10% alcohol by vol-
ume! Some types of gasoline contain
alcohol as an oxygenate. Oxygenated
gasoline may cause increased oper-
ating temperatures. Under certain
conditions, alcohol-based gasoline
may also reduce the lubricating quali-
ties of some 2-cycle mixing oils.
Generic oils and some outboard
■
oils may not be intended for use
in high-performance two-cycle
engines, and should never be
used in your Shindaiwa engine.
Use only fresh, clean unleaded gaso-
■
line with a pump octane of 87 or higher.
Mix all fuel with a 2-cycle air-cooled
■
mixing oil that meets or exceeds ISO-
L-EGD and/or JASO FC classified oils
at 50:1 gasoline/oil ratio.
Examples of 50:1 mixing quantities
WARNING!
Minimize the Risk of Fire
Gasoline 2-cycle mixing oil
liters milliliters
2.5 - 1 50 ml
5 - 1 100 ml
10 - 1 200 ml
20 - 1 400 ml
Place the saw on its side (clutch cover 1.
down), and wipe any chips or debris
from around the oil cap.
Remove the oil cap at the front of the saw.
2.
Fill the oil reservoir with bar and chain 3.
oil and replace the cap.
Wipe spilled oil from handles and con-
4.
trols before starting the saw.
When available, use Shindaiwa Pre-
■
mium bar and chain oil.
When Shindaiwa oil is not available,
■
use a premium 30-weight oil specifically
blended for bar and chain lubrication.
For cold weather operation, bar oil
■
may be thinned by mixing with clean
kerosene at a ratio of 1:1.
Oil Requirements
Filling the Oil Reservoir
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 qual-
ity lubricating oil designed for saw
chain lubrication! Never use dirty or
reclaimed oil!
