IMPORTANT SAFETY INSTRUCTIONS

WARNING: This powerful cutting machine is capable of amputating hands and feet and can throw objects that can cause injury and damage! Failure to comply with the following SAFETY instructions could result in serious

injury or death to the operator or other persons. The owner of the machine must understand these instructions

and must allow only persons who understand these instructions to operate machine. Each person operating the machine must be of sound mind and body and must not be under the influence of any substance, which might

impair vision, dexterity or judgment. If you have any questions pertaining to your machine which your dealer

cannot answer to your satisfaction, call or write the Customer Service Department at SNAPPER, McDonough, Georgia 30253. Phone: (1-800-935-2967).

PROTECTION FOR CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often

attracted to the machine and the mowing activity.

Never assume that children will remain where you last

saw them.

1. KEEP children out of the mowing area and under

the watchful care of a responsible adult.

2. DO NOT allow children in yard when machine is operated (even with the blade OFF).

3. DO NOT allow children or others to ride on machine or on attachments (even with the blades

OFF). They may fall and be seriously injured.

4. DO NOT allow pre-teenage children to operate machine.

5. ALLOW only responsible adults & teenagers with mature judgment under close adult supervision to operate machine.

6. DO NOT operate blades in reverse. STOP BLADES.

LOOK and SEE behind and down for children, pets

and hazards before and while backing.

7. USE EXTRA CARE when approaching blind corners, shrubs, trees, or other objects that may

obscure vision.

PROTECTION AGAINST TIPOVERS

Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe

injury or death. All slopes require extra CAUTION. If

you cannot back up the slope or if you feel uneasy on the slope, DO NOT mow it. Use extra care with grass

catchers or other attachments; these affect the

handling and the stability of the machine.

1. DO NOT operate machine on slopes exceeding 15 degrees (27% grade).

2. Exercise EXTREME CAUTION on slopes above 10 degrees (18% grade). Turn blades OFF when traveling uphill. Use a slow speed and avoid sudden or sharp turns.

3. DO NOT operate machine back and forth across face of slopes. Operate up and down. Practice on

slopes with blades off.

4. AVOID uphill starts. If machine stops going uphill or tires lose traction, turn blades OFF and back slowly down the slope.

PROTECTION AGAINST TIPOVERS

(Continued From Previous Column)

5. STAY ALERT for holes and other hidden hazards. Tall grass can hide obstacles. Keep away from

ditches, washouts, culverts, fences and

protruding objects.

6. KEEP A SAFE DISTANCE (at least 3 feet) away from edge of ditches and other drop offs. The machine could turn over if an edge caves in.

7. Always begin forward motion slowly and with caution.

8. Use weights or a weighted load carrier in accordance with instructions supplied with a grass catcher. DO

NOT operate machine on slopes exceeding 10

degrees (18% grade) when equipped with grass catcher.

9. DO NOT put your foot on the ground to try to stabilize the machine.

10. DO NOT operate machine on wet grass. Reduced traction could cause sliding.

11. DO NOT operate machine under any condition where traction, steering or stability is doubtful.

PREPARATION

1. Read, understand, and follow instructions and warnings in this manual and on the machine, engine and attachments. Know the controls and the proper use of the machine before starting.

2. Only mature, responsible persons shall operate

the machine and only after proper instruction.

3. Data indicates that operators age 60 and above, are involved in a large percentage of mower-

related injuries. These operators should evaluate

their ability to operate the mower safely enough to

protect themselves and others from serious injury.

4. Handle fuel with extra care. Fuels are flammable

and vapors are explosive. Use only an approved fuel container. DO NOT remove fuel cap or add fuel with engine running. Add fuel outdoors only with engine stopped and cool. Clean spilled fuel

from machine. DO NOT smoke.

5. Practice operation of machine with BLADES OFF to learn controls and develop skills.

6. Check the area to be mowed and remove all objects such as toys, wire, rocks, limbs and other

objects that could cause injury if thrown by blade or interfere with mowing.

cause sparks.

4.4.6. BATTERY TESTING

There are two types of battery tests: Unloaded and Loaded. The unloaded test is the procedure that will be discussed. It's the simplest and most commonly

used. An unloaded test is made on a battery without discharging current. To perform unloaded testing,

check charge condition using either a hydrometer or voltmeter.

1. Using a voltmeter, voltage readings appear instantly to show the state of charge. Remember to

hook the positive lead to the battery's positive terminal, and the negative lead to the negative

terminal.

2. A hydrometer measures the specific gravity of each cell. The specific gravity tells the degree of

charge; generally, a specific gravity of about 1.265 to 1.280 indicates full charge. A reading of 1.230 to

1.260 indicates the battery should be charged. The Battery Condition chart below shows the charge level as measured by syringe float hydrometer,

digital voltmeter and five ball hydrometer.

eng ne & how

The engine on your Snapper product spends Its entire life operating close to the ground at high speed creating a virtual storm of dust and dlrtl

The engine must gulp about gallons of air for

every gallon of fuel its working

ment, the air available to

heavily saturated with air- borne dirt particles.

PRIMARY MAINTENANCE

Knowing that dirt will quickly ruin an engine,

manufacturers equip their engines with extremely

efficient air cleaners to filter out the harmful dirt.

As the dirt particles are stopped,

they build up and begin to clog the outside of the filter. This

reduces the amount of air available to the engine and causes

an over-rich fuel mixture which re- sults In the following adverse

effects:

An Improperly serviced, dirt clogged air cleaner will:

1. Increase fuel consumption

2. cause power loss

3. result in hard starting

4. create smoke from fuel

5. produce carbon build-up ; Internally

6. foul spark plug electrodes

8. burn valves

9. wear out the engine pre- q

-- maturely

10. COST YOU MONEY!

Damage caused by a poorly serviced air cleaner I$ not covered under the engine warranties. So, save yourself unnecessary

expenses and undue aggravation by keeping the air cleaner properly serviced at the Intervals specified In the engine owner's manual.

It doesn't take long to service an air cleaner. Follow the specific Instructions In the engine

owner's manual for the type filter used. Pre- vent dirt from falling Into the carburetor Intake

when servicing your air cleaner. Make sure components are Installed In correct sequence

after servicing to prevent unfiltered air from entering the engine. Some servicing hints on several common types are:

'walls

Generally, wash foam-type filters

In a dlshwashlng detergent and

water solution. Rinse and wring dry, then saturate with oil and

squeeze out excess. Failure to

re-oil this type filter will ruin the

engine.

Clean paper elements by tapping lightly. Blowing with air will

rupture paper elements.

PRIMARY MAINTENANCE

Air Is also needed to keep your engine cool. Dirt, dust & debris build up to restrict

• and clog cooling air Intake screens and fins. Clean

screens and fins at frequent

Intervals. The engine blower

housing and shrouds should be removed at least once

each season or more often

l under dry, dusty conditions

for a thorough cleaning of fins.

Failure to keep external surfaces clean not only

presents fire hazards, but

causes overheating and _

resulting engine damages such as:

\ 1. distorted valve guides

valves

Use a flashlight to detect clogged or torn paper elements - replace If

damaged in any way.

engine.

An engine must also have proper lubrication. All engines use some oil. On 4-cycle engines, CHECK OIL LEVEL BEFORE EACH START-UP. , Wipe area clean around the oll check plug or

dipstick opening to keep dirt from falling Into the engine when checking the oil Always

check with the machine on a level surface. On engines with dipstick, keep the level up to,

but not over, the FULL mark. When adding o11, allow time for all of the oll to flow down the fill

tube to prevent a false full reading when the level could actually be low and result In engine

damage.

PRIMARY MAINTENANCE

On 4-cyle engines with an oil level plug,

don't be fooled into thinking the engine has

sufficient lubricating oii if you can see "some" oil in the opening - the level should always be

brought up to the point

top of the fill hole.

Change oil at regular Intervals using a a high quality oil such as Snapper's small engine

formulated 4-cycle engine elI. Refer to the engine owner's manual for oil details.

On 2-cycle engines, lubrication must be provided by an exact mixture of gasoline

and 2-cycle air-cooled engine oil A 2-cycle engine that Is mistakenly run on straight

gasoline will be ruined in less than 5 minutesl If you keep straight gasoline In

addition to pro-mixed 2-cycle engine fuel, be sure the containers are clearly marked

to avoid mix-up.

Snapper 2-cycle engines require a 32 to 1 mixture of gasoline and BIA certified TC-W

oil such as Snapper's 2-cycle engine oil Many of the 2-cycle engine oils on the market today make fantastic claims, but for

the best performance and long engine life, always usa Snapper 2-cycle oil Pre-mix the fuel and always shake the container

before filling the tank.
