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.

gine to warm up at idle 2or 3 minutes
before operating the unit.
m After the engine is warm, pick
up the unit and clip on the shoulder
strap. See page 12.
m Advancing the throttle makes the cut-
ting attachment turn faster; releasing
the throttle permits the attachment to
stop turning. If the cutting attachment
continues to rotate when the engine
returns to idle, carburetor idle speed
should be adjusted (see "Adjusting
Engine Idle" below).

trimmer head on the ground during
operation.
II Manual. The operator indexes line man-
ually with the grass trimmer stopped.
II Fixed. The operator must stop the unit
and add new lengths of trimmer line
manually.
Flail. This device, designed for clearing
weeds and light brush, features three
nylon blades attached to the head by
piw) ts.
Additional hardware may be required to
mount the Fixed Line or the Flail type trim-
mer heads.
Engine Operating Speeds
Operate the unit at full throttle while cut-
ting grass.
CAUTION!
Operation of trimmer without a cutting
attachment shield and using excessive
line length can lead to premature clutch
failure.
CAUTION!
Operation at low RPM can lead to
premature clutch failure,

Using aBlade E4-B4000
WARN|NG!
m Before working with a blade-
equipped unit, always inspect and
clean the area of objects that could
interfere with or damage the blade.
m Never use a blade near sidewalks,
fence posts, buildings or other
objects that could cause injury or
damage.
II Never use a blade for purposes
other than those for which it was
designed.
m Whenever you strike a hard object
with a blade, always stop the
brushcutter and carefully inspect
the blade for damage. NEVER
OPERATE THE BRUSHCUTTER
WITH A DAMAGED BLADE!
II A blade-equipped unit must be
equipped with a bicycle-type
handlebar or barrier bar as well
as a harness or shoulder strap.
II Always make sure the cutting at-
tachment shield is properly installed
before operating this unit.
Blade Thrust
'Blade thrust' is a sudden sideways or
backward motion of the brushcutter. Such
motion may occur when the blade jams or
catches on an object such as a sapling tree
or tree stump. BE CONSTANTLY ALERT
FOR BLADE THRUS_FAND GUARD
AGAINST ITS EFFECTS!
Brushcutter Handlebar
Abrushcutter handlebar or barrier bar
helps prevent the operator from moving
forward, or the unit moving rearward,
thus preventing inadvertent bodily contact
with the blade. ALWAYSKEEP THE
HANDLEBAR OR BARRIER BAR
SECURELY IN PLACE ON THE UNIT!
Brushcutter Shoulder Strap
A shoulder strap provides additional
protection against blade thrust. In addition,
a shoulder strap gives significant support
and comfort to help ensure safe and
efficient operation.
When operating a E4-B4000 with a blade,
make sure both the handle and shoulder
strap are adjusted to the size of the opera-
tor using the unit.
Engine Operating Speeds
Operate the unit at full throttle while cut-
ting. Best fuel efficiency is obtained by
releasing the throttle when swinging back
after a cut.
II To prevent possible engine damage, do
not allow the brushcutter to run at high
speeds without a load.
II Avoid operating the engine at low
speeds. Doing so can lead to rapid
clutch weal: In addition, slow-speed
operation tends to cause grass and
debris to wrap around the cutting head.
Operating Units with aBlade
The blade rotates counter-clockwise. For
best performance and to minimize being
stuck by debris, move the blade from right

Air Filter
_WARN|NG!
Before performing any maintenance, re-
pair or cleaning work on the unit, make
sure the engine and cutting attachment
are completely stopped. Disconnect
the spark plug wire before performing
service or maintenance work.
_WARN|NG!
Non-standard parts may not operate
properly with your unit and may cause
damage and lead to personal injury.
Using non-standard replacement parts could
invalidate your Swisher warranty.
Muffler
This unit must never be operated with
a faulty or missing spark arrester or
muffler. Make sure the muffler is well
secured and in good condition. A worn
or damaged muffler is a fire hazard and
may also cause hearing loss.
Spark Plug
Keep the spark plug and wire connections
tight and clean.
Fasteners
Make sure nuts, bolts, and screws (except
carburetor adjusting screws) are tight.
The E4 engine that powers your Swisher mod-
el is a hybrid 4-stroke engine. As a hybrid,
the engine is lubricated by oil mixed with
the gasoline and air from the carburetor that
moves through and around the internal parts
ofthe engine in a similar way that a 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 en-
gine, decreasing engine life,increasing valve
wear and the need for more frequent valve ad-
justments. To keep your E4 engine strong and
reliable, Swisher recommends that you check
and service the air filter as instructed in the
10-Hour Maintenance section that follows.
Blades
Keep blades sharp and check blade condi-
tion frequently. If a blade's performance
changes suddenly, stop the engine and
check the blade for cracks or other damage.
Replace a damaged blade IMMEDIATELY!
_WARN|N6!
II Never repair a damaged blade by
welding, straightening, or by modify-
ing its shape, An altered blade may
break during operation, resulting in
serious personal injury,
II Blades are not interchangeable
between Swisher edgers and trimmer/
brushcutter models. Operating any
unit with a blade or attachment
not approved for that unit can be haz-
ardous and may cause serious injury.
Daily Maintenance
Prior to each work day, perform the
following:
II Remove dirt or debris from the engine,
check the cooling fins and air cleaner for
clogging and clean them as necessary.
Carefully remove any accumulation of
dirt or debris from the muffler or the fuel
tank. Dirt build-up in these areas could
cause engine overheating, induce prema-
ture wear, or create a fire hazard.
m Check for loose or missing screws or
components. Make sure the cutting at-
tachment is securely fastened.
m Check the entire unit for leaking fuel or
grease.
IO-Hour Maintenance
(more frequently in dusty conditions)
1. Remove the air cleaner cover by loosen-
ing the thumb screws and lifting up. See
Figure 28A.
2. Remove and inspect the pre_filter. If the
pre-filter is torn or otherwise damaged,
replace it with a new one. See Figure 28B.
3. Clean the pre_filter with soap and water.
Let dry before reinstalling.
4. Inspect the air cleaner element. If the
element is damaged or distorted, replace
it with a new one.
5.Tap filter gently on a hard surface to
dislodge debris from element or use com-
pressed air from the inside to blow debris

Maintenance after first 139=hours,
then every 150=hours thereafter.
Combustion chamber should be decal'-
bonized, and the valve clearance should
he adjusted. It is highly recommended
that this is done by a Swisher-trained
service technician.
m Replace the spark plug annually: Use
only NGK CMR5H or equivalent resis-
tor type spark plug of the correct heat
range. Set spark plug electrode gap to
0.024-0.028 inch (0.6 -0.7 mm).
The NGK CMR5H also meets the require-
ments for electro magnetic compliance (EMC).
Valve Adjustment
1. Remove cylinder cover, rocker arm
cover, and spark plug. Rotate the
crankshaft while observing the piston
through the spark plug opening. When
the piston is at the top of the compres-
sion stroke (TDC), the valves can be
adjusted.
