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.

Filling the Fuel Tank

,_ WARNING! 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.

Minimize the Risk of Fire

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.

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.

Examples of 50:1 mixing quantities

m 1 gallon ofgasoline to 2.6 oz. mixing oil m 5 liters ofgasoline 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.

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.

Starting the Engine

,_ WARNING!

The cutting attachment may

rotate when the engine is started!

The primer system only pushes fuel through the carburetor. Repeatedly pressing the primer bulb will not flood the engine with fuel.

Figure 8

While holding the outer tube firmly with

your left hand, use your other hand to slowly pull the recoil starter handle until resistance is felt, then pull quickly to start the engine.

Make sure the cutting attachment is clear of

obstructions!

Figure 9

CAUTION!

Do not pull the recoil starter to the end of the rope travel. Pulling the

recoil starter to the end of the rope travel can damage the starter.

Figure 10

If the engine fails to start after several at- tempts with the choke in the closed posi- tion, the engine may be flooded with fuel.

If flooding is suspected, move the choke

lever to open position and repeatedly pull the recoil starter to remove the excess

fuel and start the engine. If the engine still fails to start, See the section "Starting a

Flooded Engine" for instructions.

When the Engine Starts...

[]

After the engine starts, allow the

engine to warm up at idle 2 or 3 min- utes before operating the unit.

[]

After the engine is warm, pick up the

unit and clip on the shoulder strap.

[]

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").

Stopping the Engine

OFF

Idle the engine briefly before stopping

(about 2 minutes), then slide the ignition

switch to the "O" (Engine OFF) position.

CAUT|ON!

Gasoline stored in the carburetor for extended periods can cause hard start-

ing and could also lead to increased

service and maintenance cost.

Remove the remaining fuel from the fuel lines and carburetor.

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 1 and 2 until the engine will no longer start.

II Remove the spark plug and pour about

1/4 ounce of 2-cycle mixing oil into the cylinder through the spark plug hole. Slowly pull the recoil starter 2 or 3 times so oil will evenly coat the interior of the engine. Reinstall the spark plug.

II Before storing the unit, repair or replace

any worn or damaged parts.

II Remove the air cleaner element from the

carburetor and clean it thoroughly with soap and water. Let dry and reassemble

the element.

m Store the unit in a clean, dust-free area.
