_CuelFill Cap

Oil Fill Cap

FILL GAS

Fill the fuel tank with clean, fresh, unleaded grade automotive gasoline, Be sure that the container you pour the gasoline from is

clean and free from dust or other foreign

particles. Never use gasoline that may be

stale from long periods of storage in the

container.

/_ CAUTION: Never fill the gas tank

while the engine is running or hot.

Immediately wipe off any spilled gasoline

before attempting to start the engine.

,_ CAUTION: Gasoline is flammable

and caution must be used when handling or storing it. Do not fill fuel tank while Edger/ Trimmer is running, hot, or when in an enc)osed area. Keep away from open flame, electrical spark, and do not smoke while filling the fuel tank. Never lilt fuel tank completely; but fill the tank to within 1/4-!/2 inch from the top to provide space for expansion of fuel. Always fill fuel tank outdoors and use a funnel or spout to prevent spilling. Make sure to wipe up any spilled fuel before starting the engine. Store gasoline in a clean, approved container, and keep the cap in place on the container. Keep gasoline in a cool, well ventilated place; never in the house. Never buy more than a 30 day supply of gasoline to assure volatility. Gasoline is intended to be used as a fuel for internal combustion engines therefore, do not use gasoline for any other purpose. Since many children like the smell of gasoline, keep it out of their reach because the fumes are dangerous to inhale, as well as being explosive.

,_ WARNING: Experience indicates that 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 engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain fuel tank, start engine and let it run until fuel lines and carburetor

are empty. Usa fresh fuel next season. See

Storage Instructions for additional informa- tion. Never use engine or carburetor

cleaner products in the fuel tank or perma-

nent damage may occur.

TO START THE ENGINE

Before starting the engine, be sure you have read and understood all the instruc-

tions on the preceding pages. The Edged Trimmer is equipped with a recoil starter. The operation of the engine is controlled by the throttle control lever.

• Pull the clutch lever all the way back or up to the rearmost hole to raise and disengage the blade.

• Move the throttle control lever, see figure on page 7 to the FAST position.

• Push primer button five times, see figure on page 7. Wait about two seconds

between each push. NOTE: Do not use primer button to

restart a warm engine after a short shutdown.

• To start engine, grasp the engine starter

handle firmly with your right hand.

• Hold the edger handle firmly with your

left hand.

• Pull up sharply on the recoil starter

handle. DO NOT allow the starter rope to snap back, let it rewind slowly while holding the starter handle. If engine fails

to start after three pulls, push primer

button two times and pull starter rope again.

• When the engine starts. Push throttle control lever up to increase speed; down

to decrease speed. Run at full engine speed during normal use.

NOTE: The cutting blade speed is controlled by the engine speed. To reduce the cutting blade speed, push

down on the throttle control lever. To

increase the blade speed, push the

_rottlecontrolleverup

• Tostoptheengine,makesuretheclutch leverisallthewaybackorupandmove thethrottlecontrollevertotheSTOP

position.

/_ CAUTION: Never run the engine indoors or in a poorly ventilated area. Engine exhaust contains carbon monoxide,

an odorless and deadly gas. Keep hands, feet, hair and loose clothing away from any moving parts on the engine or edger/ trimmer. Avoid the muffler and surrounding areas. Temperatures may exceed 150 ° F.

EDGING TIPS

• Edging is best performed when conditions

are dry. If the soil is to wet, dirt becomes packed in and around the blade causing

premature belt wear and decreased

performance.

• If dirt does become packed around the

blade, stop the engine, remove the spark plug wire, and remove the packed debris before continuing to edge.

• If very deep edging is required, we recommend that a shaltow cut be made

first, then cuts at greater depth until the desired depth is obtained.

• Uniform edging can be performed when

the blade guide rides on and against the

surface which you are edging.

• Edging can be customized by varying the number of passes and by the distance

your blade is from the surface you are

edging.

GENERAL RECOMMENDATIONS The warranty on this Edger/Trimmer does

not cover items that have been subjected to operator abuse or negligence. To receive

full value from the warranty, the operater

must maintain the Edger/Trimmer as in- structed in this manual. The above chart is

provided to assist the operator in properly maintaining the edger/trimmer.

LUBRICATION

• After each 25 hours of use of your edger/

trimmer, apply lightmachine oil to all moving parts, particularly the wheels.

• The oil in the engine crankcase must be changed after the first 2 hours of opera- tion and after each 25 hours of use there-

after. See OIL RECOMMENDATIONS in

OPERATIONAL sectional in this manual

TO CHANGE OIL

• Disconnect the sparkplugwire from the

spark plug.

• Remove the oildrainplug as shown be-

low and drain the oil into a flatpan.

• After draining all the oil,reinstallthe oil

drain plug securely.

NOTE; The oil will drain mare freely when the engine is warm.

VIEW FROM REAR

il Drain Plug

AIR CLEANER

Replace the filter once a year; more often

under dusty or dirty conditions. DO NOT attempt to clean or oil the air filter. To instaif a new air filter, do the following:

• Disconnect the spark plug wire from the

spark plug.

• Turn the cover as shown below to the left

counterclockwise and remove the cover and the air filter from the flange.

• Discard the air filter.

• Clean the cover and the flange thor+

oughly,

• Insert the new air filter into the cover.

• Push the cover firmly against the flange

and turn it to the right clockwise as far as it will go as shown in figure below. Be

sure the retainers are locked around the

flange,

• Reconnect the spark plug wire.

• Flange

Slot

Tab

Turn cover to the right (clockwise) ot install

Z_ CAUTION: Never run the engine without the air cleaner element installed. A

defective air cleaner can result in loss of

engine power and can cause excessive wear or damage to the engine components

if dirt or dust is permitted to enter the

engine through the carburetor. A damaged air cleaner, or one that is clogged with dust

or dirt should be replaced immediately.

SPARK PLUG

Clean the spark plug and reset the gap

periodically. Before removing spark plug,

clean the area around its base to prevent dirt from entering into the engine, Replace the spark plug if the electrodes are pitted or

burned or if the porcelain is cracked. Clean the spark plug by carefully scraping the

electrodes with a knife or screwdriver (do

not sand blast or use a wire brush). Be sure the spark plug is clean and free of foreign

material. Check the electrodes gap with a

wire feeler gauge and reset to .030 if

necessary. If a new spark plug is needed,

refer to the Engine manual for the proper

replacement spark plug.

Before reinstalling the spark plug, coat the

threads lightly with graphite or light oil to

insure easy removal. Tighten the spark plug

firmly into the engine. If a torque wrench is

available, torque the spark plug to 15 foot-

pounds.

/'_ CAUTION: Always stop the engine and disconnect the spark plug wire before

making any repairs to the edgerttrimmer.
