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 operat-
ing temperatures. Under certain con-
ditions, alcohol-based gasoline may
also reduce the lubricating qualities of
some 2-cycle mixing oils. Generic oils
and some outboard oils may not be
intended for use in high-performance
engines, and should never be used in
your Swisher engine.
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.
m Use only fresh, clean unleaded gasoline
with a pump octane of 87 or higher.
m Mix all fuel with a 2-cycle aipcooled mix-
ing 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
m 1 gallon of gasoline to 2.6 oz. mixing oil
m 5 liters of gasoline to 100 ml. mixing oil
Mix only enough fuel for your immediate
needs! If fuel must be stored longer than 30
days and Swisher E4 Engine Oil with fuel
stabilizer is not used, it should first be treated
with a fuel stabilizer such as STA-BIL TM.
Swisher E4 Engine Oil is a registered JASO
FC classified oil and also meets or exceeds
ISO-L-EGD performance requirements.
Swisher E4 engine oil is recommended for
use in all Swisher low emissions engines and
also includes a fuel stabilizer.
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. Avoid over-
filling and wipe off any fuel that may
have spilled.
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 10
feet (3 meters) away from a fuel stor-
age 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.
1. Place the trimmer on a fiat, level surface.
2. Clear any dirt or other debris from
around the fuel filler cap.
3. Remove the fuel cap, and fill the tank
with clean, fresh fuel.
4. Reinstall the fuel filler cap and tighten
firmly.
