NOTE: Although multi-vlscastty oils

(5W30, lOW30, etc.) Improve starting In

cold weather, these multi-viscosity oils

will result in Increased oil consumption

when used above 32°F. To avoid possible

engine damage from running low on oil,

frequently check your engine oil level.

Check The Engine Oil

Before each use, check the engine oil as

follows:

1. Putthe trimmerona levelsurface.

2. Remove the oil fill cap/dipstickshownin

Figure8.

How To Fill With Gasoline

NOTICE: ENGINES WHICH ARE CERTI-

FIED TO COMPLY WITH CALIFORNIA AND

US EPA EMISSION REGULATIONS FOR

ULGE ENGINES: Are certified to operate on

regular unleaded gasoline. Include the follow-

ing emission control system(s): EM, TWC (if

so equipped). Include any user adjustable

containeris clean and free from dustor other

foreign particles.Never use gasolinethat is

stalefrom long periodsof storage, Reinstall

fuelcap.

CAUTION: Alcohol blended fuels (called

gasohol or using methanol) can attract

moisture which leads to separation and

formation of acids during storage. Acidic

gas can damage the fuel system of an en-

TRIMMER TIPS

d_llb WARNING: Debris such as sticks,

gravel or rocks, can be thrown

with sufficient force to cause per-

sonal Injury or property damage.

Set the throitte controlin the FAST posi-

tion. If the weeds er grass are tall and

thick, operate the tdmmer at a slower

walkingspeed.

Frequentlydean the undersideofthetrim-

merto removeany grassbuildup.See the

Maintenancesectionfordetails.

For best results and longer lasUng line,

use the ends of the line to do the cutting.

This is easily done by moving slowly

through very thick or heavy weeds.

• If the trimmer li.es become ton short, it will

HOW TO

REPLACE THE TRIMMER LINE

Forthe best performance,use a heavy

gauge (0.155" diameter)trimmer line. Cut

the lengthof the trimmer line to 21.5 inches.

Use the lengthguide,locatedon the shield,

to makesurethe trimmer line is the correct

length. See Figure14. Do notallowthe

lengthofthe linesto vary morethan one

inch.Thisis importantto make sure the trim-

mer head is balancedanddoes not vibrate.

IMPORTANT:To extend the life of the trim-

mer line, keep thetrimmer line moist. Ifnot

kept moist, the nylon trimmer line will be-

come dry end brittle. Keep extra trimmer

line in a can of water.The line willthen stay

flexible and easyto change. A flexible line

will also lest much longer.

line while inside a building, near

afire, or while you smoke. Gaso-

line fumes can cause an explo-

sion or a fire.

When the tdmmer is put in storage for thirty

days or more, follow the steps below to

mum performance for the next season.

Engine

IMPORTANT: It is important to prevent gum

deposits from forming In fuel system parts

such as the carburetor, fuel filter, fuel hose,

and tank during storage. Also, using alco-

hol-blended fuels (called gasohol, ethanol

or methanol) can attract moisture which

leads to separation and formation of acids

during storage. Acidic gas can damage the

fuel system of an engine while In storage.
