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.

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.
