introduction
The Swisher E4 series hand held power
equipment has been designed and built to
deliver superior performance and reliability
without compromise to quality, comfort,
safety or durability.
Swisher engines represent the leading
edge of high-performance engine technol-
ogy, delivering exceptionally high power
with remarkably low displacement and
weight. As an owner/operator, you'll soon
discover for yourself why Swisher is simply
in a class by itself!
The information contained in this
owner's/operator's manual describes units
available at the time of publication.
Swisher reserves the right to make

1. With the gear case output shaft facing
up, rotate the gearshaft and holder A
until the hole in holder A aligns with the
matching hole in the gear case flange,
and then lock the holder to the gear by
inserting the long end of the hex wrench
through both holes. See Figure 10.
2. Using the combination spark plug/
screwdriver wrench, remove the shaft
bolt and bolt guard. See Figure 10.
Make sure holder B is installed on the gear-
case with tile splined hole engaging the gear-
case shaft.
3. Using the hex wrench to secure Holder
A, install and hand-tighten the trimmer
head (counter-clockwise m install).

Installing aBlade
Turn the E4-B4000 upside down so the
gear case output shaft is facing UP and
remove the shaft bolt, bolt guard and
holder B from the gear case shaft.
1. Align the hole in blade holder A with the
matching hole in the gear case flange
and then temporarily lock the output
shaft by inserting a hex wrench
through both holes.
See Figure 12.
2. Slide the safety clip off-center.
See Figure 13.
3. Fit the blade over the safety clip and
then center it over the flange on holder
A. See Figure 14.

the bolt firmly in a counter-clockwise
direction.
7. Remove the hex wrench.

Mixing Fuel
CAUT|ON!
Some types of gasoline contain alcohol
as an oxygenate. Oxygenated gaso-
line may cause increased operating
temperatures. Under certain condi-
tions, alcohol-based gasoline may
also reduce the lubricating qualities of
some 2-cycle mixing oils. Never use
any type of gasoline containing more
than 10% alcohol by volume! 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 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
m I gallon ofgasoline to 2.6 oz. mixing oil
m 5liters ofgasoline to 100ml. 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 Riskof Fire
NEVER smoke or light fires near the
engine.
ALWAYS stop the engine and allow
it to cool before refueling. Avoid
overfilling 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 re-
paired before using the unit.
ALWAYS move the unit at least 10 feet
(3 meters) away from a fuel storage
area or other readily flammable materi-
als 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 flat, 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.
