Mixing Fuel
CAUT|ON!
Never use any fuel containing more
than 10% alcohol by volume! Some
gasolines contain alcohol as an oxy-
genate! Oxygenated fuels may cause
increased operating temperatures.
Under certain conditions, alcohol-
based fuels may also reduce the lubri-
cating qualities of some mixing oils.
Generic oils and some outboard
motor oils may not be intended for
use in high-performance air cooled
2-cycle engines, and should never be
used in your Swisher engine!
CAUT|ON!
This engine is designed to oper-
ate on a 50:1 mixture consisting of
unleaded gasoline and a premium
2-cycle mixing oil only. Use of non-
approved mixing oils can lead to
excessive maintenance costs and/or
engine damage.
m Use only fresh, clean unleaded gasoline
with a pump octane rating of 87 or higher.
m 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.
Example of 50:1 mixing quantities:
m 5 liters of gasoline to 0.1 liter mixing oil.
m i gallon of gasoline to 2.6 oz. 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 is recommended for use in all
Swisher low emissions engines and also
includes a fuel stabilizer.

ThrotUe Control
The E4-A3000 and E4-A4000 are equipped
with a multi-function throttle control. The
"Cruise" function allows the operator to
use a thumb controlled lever for constant
speed use without using the throttle trigger.
This is useful for limiting the fatigue caused
from holding the throttle for extended
periods of time.
On the opposite side, a two position
"Limiter" control allows full engine speed
when set for "Turbo" or limits the throttle
to a pre-set engine speed when set to low
noise (dB) setting.

Operating Tips
In the hands of an experienced operatol;
the E4-A3000 and E4-A4000 can efficiently
move a wide variety of debris ranging from
grass clippings to gravel. As a general rule,
operate your leaf blower at the lowest throt-
tle setting required to get the job done:
m Use low throttle settings when clearing
lightweight materials from around lawns
or shrubbery.
Figure 11
Adjusting Throttle Limiter:
1. Remove the plug located at the top of
the throttle assembly. See Figure 12.
2. Move the throttle limiter lever to the
"dB" setting. See Figure 12.
m Use medium to higher throttle settings
to move grass or leaves from parking
lots or walkways.
m Use full throttle when moving heavy
loads such as dirt or snow.
With the throttle limiter adjusted to 7,000 min-1
(rpm), the E4-A3000 will have a sound level of
65 dB(A) measured at 15 m (50 feet).
With the throttle limiter adjusted to 6,500 min -1
(rpm), the E4-A4000 will have a sound level of
65 dB(A) measured at 15 m (50 feet).
" 0 " ,
Leaf blower noise increases at higher
throttle settings! Always use the lowest
throttle setting required to get the job
done!
Maintenance
Maintenance, replacement or repair of
emission control devices and systems may
be performed by any repair establishment
or individual, However, warranty repairs
must be performed by a dealer or service
center authorized by Swisher. The use
of parts that are not equivalent in perfor-
mance and durability to authorized parts
may impair the effectiveness of the emis-
sion control system and may have a bear-
ing on the outcome of a warranty claim.
Air Filter
The E4 engine that powers your Swisher
model is a hybrid 4-stroke engine. As a
hybrid, the engine is lubricated by oilmixed
with the gasoline and air from the carburetor
that moves through and around the internal
parts of the engine in a similar way that a
Daily Maintenance
_ WARN|NG!
To reduce fire hazard, keep the engine
and muffler free of dirt, debris, and
leaves.
Prior to each workday, perform
the following:
m Remove all dirt and debris from leaf
blower exterior and the engine. Check
the cooling fins and air cleaner for clog-
ging and clean as necessary.
_ WARN|NG!
Before performing any maintenance,
repair or cleaning work on the unit,
make sure the engine is completely
stopped. Disconnect the spark plug
wire before performing service or
maintenance work.
2-stroke engine is lubricated. Without the
heavy duty 2-stage air filter equipped on all
E4 engines, dust and dirt could also move
through the engine, decreasing engine life,
increasing valve wear and the need for more
frequent valve adjustments. To keep your E4
CAUT|ON!
The engine is cooled by air drawn
into the air intake cover on the leaf
blower housing. The leaf blower fan
then pushes the cooling air through an
opening in the fan housing, forcing it
past the cylinder cooling fins. Failure to
keep the cooling system and its pas-
sages clear of debris will likely result in
engine overheating, a major cause of
serious engine problems that can lead
to failure.

Long Term Storage
Whenever the unit will not be
used for 30 days or longer, use
the following procedures to prepare it for
storage:
Clean external parts thoroughly.
m Drain all the fuel from the fuel tank.
All stored fuels should be stabilized with
a fuel stabilizer such as STA-BIL TM if
Swisher E4 Engine Oil with fuel stabilizer
is not used.
To remove the remaining fuel from the
fuel lines and carburetor and with the fuel
drained from the fuel tank.
1. Prime the primer bulb until no more fuel
is passing through.
2. Start and run the engine until it stops
running.
3. Repeat steps i and 2 until the engine will
no longer start.
CAUT|ON!
Gasoline stored in the carburetor for
extended periods can cause hard start-
ing, and could also lead to increased
service and maintenance costs.
m Remove the spark plug and pour
about 10 cm :_(1/4 oz.) of 2-cycle mixing
oil into the cylinder through the spark
plug hole. Slowly pull the recoil starter
2 or 3times so oil will evenly coat the
interior of the engine. Reinstall the spark
plug.
m Before storing the unit, repair or replace
any worn or damaged parts.
m Remove the air cleaner element from the
unit and clean it as outlined on page 10.
m Store the unit in a clean, dust-free area.
