Priming
Before the pump can develop suction or
“lift” at the water source, the pump impel-
ler must first be primed by filling the pump
housing with water. Once the E4-W4000
has been primed, additional priming
should be required only if the pump has
been drained or otherwise emptied.
Remove the filler plug at the top of the
pump housing. Use care not to lose the
sealing ring beneath the filler plug.
1.
Filler Plug
CAUTION!
Never allow the pump to run dry!
Operation without water can permanently
damage the pump seals.
IMPORTANT!
A damaged or missing ller plug seal may
allow air to leak into the pump housing. Air
leakage can lower performance!
Fill the pump housing through the prim-
ing port (Figure 2) with clean water
until water overflows from the filler plug
hole on the pump body.
Replace and securely tighten the filler plug.
2.
3.
Install the Suction and Discharge Hoses
Assemble a barbed hose fitting, ring
nut, and gasket as shown, and thread
the completed hose fitting assembly
onto the pump suction port. Assemble
the remaining hose fitting to the pump
discharge port.
Push a 1.0" suction hose (not provided)
over the suction hose fitting on the
pump body, and secure with a 1.0"
hose clamp as shown. Working at the
opposite end of the suction hose, use
a second 1.0" hose clamp to install and
secure the suction strainer.
1.
2.
IMPORTANT!
Place the pump as close to the water
source as possible. Increases in suction lift
will lower pump performance. Do not ex-
ceed maximum suction head of 26 feet.
CAUTION!
This pump is intended for pumping
fresh water only.
Ingested debris can damage the
pump impeller and seals.
Never operate the pump if the
strainer is missing or damaged.

Mixing Fuel
Example of 50:1 mixing quantites:.
1 gallon of gasoline to 2.6 oz. mixing oil.
5 liters of gasoline to 100 ml. mixing oil.
■
■
CAUTION!
Some gasolines contain alcohol as
an oxygenate! Oxygenated fuels may
cause increased operating tempera-
tures. Under certain conditions, alco-
hol-based fuels may also reduce the
lubricating qualities of some mixing
oils. Never use any fuel containing
more than 10% alcohol by volume!.
Generic oils and some outboard mo-
tor oils may not be intended for use in
high-performance air-cooled 4-cycle
and 2-cycle 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 a premium 2-cycle mix-
ing oil only. Use of non-approved mix-
ing oils can lead to excessive mainte-
nance costs and/or engine damage.
Filling the Fuel Tank
Place the E4-W4000 on the ground or
on a flat surface.
Clear any dirt or other debris from
around the fuel filler cap.
Remove the fuel cap, and fill the fuel
tank with clean, fresh fuel mixture.
Replace and firmly tighten the fuel cap.

WARNING!
Minimize the risk of re!
IMPORTANT!
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 rst be
treated with a fuel stabilizer such as STA-
BIL™.
nUse only fresh, clean unleaded gasoline
with a pump octane of 87 or higher.
nMix 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.
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.

Operating Tips for Maximum Performance
Minimize friction by using the correct 1.0"
ID suction and discharge hoses specified,
with a minimum of connections. Keep all
hose runs as short as possible.
Keep the suction head (vertical lift) as short
as possible. Do not exceed the pump’s
maximum suction head of 26 feet.
Avoid air leaks.
All suction-side connections must be
tightly secured.
Make sure the filler cap and drain plug
on the pump housing are tight and free
from leakage.
Protect the discharge hose from crushing-
type damage, especially from motor
vehicles.
Abrasive debris can damage the pump
impeller and seals, and should be avoided.

General Maintenance
Mufer
This unit must never be operated with a
faulty or missing spark arrester or muf-
fler. 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.
NOTE:
Using non-standard replacement parts could
invalidate your Swisher warranty.
WARNING!
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 ser-
vice or maintenance work.
WARNING!
Non-standard parts may not operate
properly with your unit and may cause
damage and lead to personal injury.
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
of the 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.
Air Filter

11
50-hour Maintenance
Every 50 hours of operation
(more frequently in dusty or
dirty conditions):
Remove and clean the cylinder cover and clean
dirt from the cylinder fins.
Use a hooked wire to extract the fuel filter
from inside the fuel tank. See Figure 14.
1.
2.
CAUTION!
Make sure you do not pierce the
fuel line with the end of the hooked
wire. The line is delicate and can be
damaged easily.
Every 10 to 15 hours of operation:
Remove and clean the spark plug. Adjust the
spark plug electrode gap to 0.024 - 0.028 inch
(0.6 - 0.7 mm). If the spark plug must be re-
placed, use only an NGK CMR5H or equiva-
lent resistor type spark plug of the correct
heat range. See Figure 13.
CAUTION!
Before removing the spark plug,
clean the area around the plug to pre-
vent dirt and debris from getting into
the engine’s internal parts.
Clean the spark plug
and check the gap at
the electrode.

NOTE:
The NGK CMR5H also meets the requirements
for electro magnetic compliance (EMC).
Remove and replace the filter element.
Before reinstalling the new filter element,
inspect the condition of all the fuel sys-
tem components (fuel pick-up line, fuel
return line, tank vent line, tank vent, fuel
cap and fuel tank). If damage, splitting
or deterioration is noted, the unit should
be removed from service until it can be
inspected or repaired by a Swisher-trained
service technician.

139/150-Hour Maintenance
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.
2. Loosen adjuster locknut so that the 2.5
mm Allen socket head adjustment screw
can turn freely.
3. Insert 0.10 mm (0.004") feeler gauge be-
tween valve stem tip and rocker arm.
4. Turn adjustment screw (clockwise =
tighter, counter-clockwise = looser) until
feeler gauge is almost snug. Back off
just enough to allow gauge to slip out
with limited resistance.
5. While holding the adjustment screw in
place with the Allen driver, tighten the
locknut with a wrench.
6. Turn engine over several times, and
returnthe to TDC-compression. Recheck
with proper feeler gauge to make sure
clearance adjustment did not change as a
result of tightening the locknut. Readjust
as necessary.
7. Replace rocker arm cover gasket to as-
sure proper sealing and install cover.
IMPORTANT!
If a new gasket is not available and/or the
old gasket is not damaged, the old gasket
may be reused. Never use cracked or
damaged gaskets!
CAUTION!
nPerforming a valve adjustment in-
correctly may cause hard starting
and/or can damage the engine.
nIf you are unfamiliar with this en-
gine or uncomfortable with this
procedure, consult with an autho-
rized E4 Swisher servicing dealer.
Maintenance after rst 139-hours,
then every 150-hours thereafter.
Combustion chamber should be decar-
bonized, and the valve clearance should
be adjusted. It is highly recommended
that this is done by a Swisher-trained
service technician.
1.
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).
2. NOTE:
The NGK CMR5H also meets the requirements
for electro magnetic compliance (EMC).
