Operator Safety

Important Operator 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. Children who have been given rides in the past may suddenly appear in the mowing area for another ride and be run over or backed over by the machine. 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 other than the operator.

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, attachments or towed equipment (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 tipover 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. Refer to the Slope Guide at the end of this manual.

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 starting, stopping or turning on slopes. If machine stops going uphill or tires lose traction, turn blades OFF and back slowly straight down the slope.

5. STAY ALERT for holes and other hidden hazards. Tall grass can hide obstacles. Keep away from ditches, washouts, culverts, fences and protruding objects.

Protection against Tipovers

(Continued From Previous Column)

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. Choose a low enough speed setting so that you will not have to stop or shift on a slope. Tires may lose traction on slopes even though the brakes are functioning properly.

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

13. Always keep the machine in gear when going down slopes. DO NOT shift to neutral (or actuate hydro roll release) and coast downhill.

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.

Operation (Continued) 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 oper-

ate 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.

Operation

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.

Reverse Lockout Mechanism Override

1. Stop the machine. Stop the blade.

2. Depress and hold the Override Lever.

3. Depress and hold the Blade Pedals. Release the Override Lever.

4. Move the blade lever forward to “ON” position.

LOOK and SEE behind and down for children, pets and hazards before and while backing.

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.

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.

WARNING

IMPORTANT: Never place anything in the battery other than the specified electrolyte.

5. Slow charge the battery at 1 amp for 2 hours to bring the battery to full charge.

6. After charging, check the level of electrolyte and add as needed to bring the level to 3/16” above the cell plates.

7. Reinstall the cell caps.

8. Remove the hair pin and swivel from the deck support to allow clearance for battery installation.

9. Slide the battery partially into the battery housing.

10.Connect the red positive (+) cable (B, Figure 49) first, from the wiring harness to the positive terminal (+) on the battery, using the bolt and nut provided in the hardware bag. Connect the black negative (-) cable (A) last, to the negative terminal (-) on the battery, using the bolt and nut. Apply a small amount of grease over the terminals to prevent corrosion.

11.Insert the battery completely into the battery housing.

12.Reinstall the battery cover (A, Figure 48).

13.Reinstall the swivel and hair pin for the deck support.

WARNING

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 the terminal cover located on the battery harness. This prevents metal from touching the positive terminal, which could cause sparks.

Engine Power Rating Information: The gross power rating for individual gas engine models is labeled in accordance with SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide array of products on which engines are placed and the variety of environmental issues applicable to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment (actual "on-site" or net power). This difference is due to a variety of factors including, but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.
