Mixing Fuel; Filling The Fuel Tank; Bar Oil - Shindaiwa 502s Owner's/Operator's Manual

Mixing fuel

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.

Filling the fuel tank

WARNING!
Minimize the Risk of Fire
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

Bar Oil

Oil Requirements
■
When available, use Shindaiwa Pre-
mium bar and chain oil.
Filling the Oil Reservoir
1. Place the saw on its side (clutch cover
down), and wipe any chips or debris
from around the oil cap.
2. Remove the oil cap at the front of the saw.
3. Fill the oil reservoir with bar and chain
oil and replace the cap.
4. Wipe spilled oil from handles and con-
trols before starting the saw.
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.
■
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.
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.
■
When Shindaiwa oil is not available,
use a premium 30-weight oil specifically
blended for bar and chain lubrication.
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!

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. Place the unit on a flat surface with the
fuel cap up.
2. Clear any chips or other debris from
around the fuel filler cap.
3. Remove the fuel cap and fill the tank
with clean, fresh 2-cycle fuel mix. Avoid
overfilling and fuel spillage.
4. Wipe any spilled fuel and move the saw
at least 10 feet (3 meters) from the fuel-
ing point before starting the engine.
■
For cold weather operation, bar oil
may be thinned by mixing with clean
kerosene at a ratio of 1:1.
