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. Check brakes frequently; adjust, repair or replace as needed.

5. Keep all bolts, nuts and screws properly tight. Check that all cotter pins are in proper position.

6. Always provide adequate ventilation when running engine. Exhaust gases contain carbon monoxide, an odorless and deadly poison.

7. Disconnect negative (black) cable from battery before performing maintenance or service. Cranking engine could cause injury.

8. DO NOT work under machine without safety blocks.

9. Service engine and make adjustments only when engine is stopped. Remove spark plug wire(s) from spark plug(s) and secure wire(s) away from spark plug(s).

10. DO NOT change engine governor speed settings or overspeed engine.

11. Lubricate machine at intervals specified in manual to prevent controls from binding.

12. Mower blades are sharp and can cut. Wrap the blades or wear heavy leather gloves and use

CAUTION when handling them.

13. DO NOT test for spark by grounding spark plug next to spark plug hole; spark plug could ignite gas exiting engine.

14. Have machine serviced by an authorized SNAPPER dealer at least once a year and have the dealer install any new safety devices.

15. Use only genuine SNAPPER replacement parts to assure that original standards are maintained.

16. If battery is removed, DO NOT operate engine without insulating Positive + battery cable terminal with electrical tape, or sparking from the battery

cables can result.

Section 2 - OPERATING INSTRUCTIONS

2.6 REVERSE LOCKOUT MECHANISM

Data indicates that tragic back-over accidents occur

each year. These accidents usually involve unsupervised children. Many times these children have

been given rides on the machine and have been trained to view this potentially dangerous piece of machinery as fun rather than being taught how to avoid danger.

This riding mower has a Reverse Lockout Mechanism. This mechanism prevents the mower from being shifted

into reverse with the blade running. To shift into reverse

you must first stop the blade by releasing the blade pedals and then shift to reverse. It is our

recommendation that this mechanism remain functional and the operator of this equipment develop the habit of

never backing up with the blade running. As the Safety Instructions Indicate, DO NOT operate blades in

reverse. STOP BLADES, LOOK AND SEE BEHIND

AND DOWN for children, pets and hazards before

and while backing.

We realize that this could cause a change to your previous mowing method but we encourage you to

adjust to this new system. Do not defeat the Reverse

Lockout Mechanism.

2.6.1. Reverse Lockout Mechanism Override

1. Stop machine. Stop blade.

2. Depress and hold Override Lever.

3. Depress and hold Blade Pedals. Release

Override Lever.

4. Move blade lever forward to "ON" position.

IaLn_dOdOhKazandsSbEeEfbrWARNl!NGk[n° rg.ChiIdren,p_ets I

IMPORTANT: DO NOT use the Reverse Lockout Mechanism Override as the normal operating mode. To

return to the Reverse Lockout Mechanism mode, release blade pedals to turn blade off. The Override will

reset to Reverse Lockout. Check the Reverse Lockout Mechanism frequently for proper function. With the

blade pedals depressed, the shift lever must not go into reverse. DO NOT operate machine if Reverse Lockout

Mechanism is not functioning properly. Contact your local Snapper dealer for assistance.

If you operate your mower near roadways or use

attachments that require quicker shifting to reverse, there is an override lever provided. This lever can be pushed and held before starting the blade and will allow

reverse operation until the blade pedals are released, at which time the system will return to its Reverse Lockout

mode. This feature should never be selected unless you

are absolutely sure that no children or others are present in the mowing area and that all children are

away and supervised by a responsible adult.

DANGER

LOOK and SEE behind and down for children, pets

and hazards before and while backing.

BLADES must be turned off before backing

machine.

DO NOT allow children on machine (even with

blades off) or in yard when mowing.

Section 3 - MAINTENANCE

WARNING

DO NOT attempt any adjustments, maintenance,

service or repairs with the engine running. STOP engine. STOP blade. Engage parking brake. Remove

key. Remove spark plug wire from spark plug and

secure away from plug. Engine and components are

HOT. Avoid serious burns, allow all parts to cool before working on machine. Fuel Filler Cap and vent must be closed securely to prevent fuel spillage.

Connect negative (-) cable (black) last, to negative terminal (-) on battery using bolt and nut. Apply a small amount of grease over terminals to prevent

corrosion.

Shield the positive terminal with terminal cover located on battery harness. This prevents metal from

touching the positive terminal which could cause sparks.

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.

WARNING

(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.
