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

4.6.6. 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 chart on the next page shows the charge level as measured by syringe float hydrometer, digital

voltmeter and five ball hydrometer.

Shield the positive terminal with terminal cover I

located on battery harness. This prevents metal from

touching the positive terminal which could cause l sparks. I

(Battery Testing Chart on Next Page)

IMPORTANT: 3/16" above cell plates is the recommended

level. DO NOT place anything in battery other than specified

electrolyte.

PRIMARY MAINTENANCE

illustration of

how dirt can

& how

maintenance

can protect it!

Snapper uses the best avail- able engines and components n In their products in order to

provide long, satisfactory

service. However, proper care is essential In _"

prolonging engine life. Dirt Is your engine's enemy

number 11

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

PRIMARY MAINTENANCE

"; .. o

The engine must gulp about 12,000

gallons of air for used. Because of

its working environ- ment, the air available

to your Snapper engine Is " heavily saturated with air-

borne dirt particles.

g 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 unburned fuel

5. produce carbon build-up ; Internally

6. foul spark plug electrodes

7. score cylinder walls

8. burn valves

9. wear out the engine pre- maturely

10. COST YOU MONEY!

Damage caused by a poorly serviced air cleaner Is not covered under the engine

warranUes. 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 like long to ssrvlce 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 ssrvicing 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:

PRIMARY MAINTENANCE

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.

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

damaged In any way.

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

tunder 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

2. sticking valves

t_°o. 3. scuffed, scored

,.,. walls

4. overspeedlng

5. loss of power

6. complete failure of engine.

Dirt can also be introduced

into an engine In dirty fuel

from a contaminated container. Always use clean

fresh fuel from a clean

container to guard against dirt, sludge and water

contamination.

Be aware that fuel breaks down in storage and forms gummy compounds which

will block carburetor pass- ages. Never use fuel more

than 3 months old. Drain tank then run the engine out

of fuel before storing during the off-season.

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 at the

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 oil 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 addlUon to pre-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 o11. 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 tilting the tank.
