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

Carbon Monoxide Warning

WARNING

POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a poisonous gas that could kill you in minutes. You CANNOT see it, smell it, or taste it. Even if you do not smell exhaust fumes, you could still be exposed to carbon monoxide gas. If you start to feel sick, dizzy, or weak while using this product, shut it off and get to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

• Operate this product ONLY outside far away from windows, doors and vents to reduce the risk of carbon monoxide gas from accumulating and potentially being drawn towards occupied spaces.

• Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms with battery back-up according to the manufacturer’s instructions. Smoke alarms cannot detect carbon monoxide gas.

• DO NOT run this product inside homes, garages, basements, crawlspaces, sheds, or other partiallyenclosed spaces even if using fans or opening doors and windows for ventilation. Carbon monoxide can quickly build up in these spaces and can linger for hours, even after this product has shut off.

• ALWAYS place this product downwind and point the engine exhaust away from occupied spaces.

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).

Protection Against Tip-Overs/Roll-Overs

Slopes are a major factor related to loss-of-control and tipover/roll-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 10 degrees (18% grade).

2. 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.

6. KEEP A SAFE DISTANCE (at least two mower widths) 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. DO NOT begin forward motion while the machine is rolling backwards. A rearward tip-over may result.

9. Use weights or a weighted load carrier in accordance with instructions supplied with a grass catcher or other attachments. DO NOT operate machine on slopes exceeding 10 degrees (18% grade) when equipped with grass catcher or other attachments.

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

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

Not for

Reproduction

12. 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.

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

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

15. Machine stability is tested in accordance with the applicable ANSI B71 standard using an operator weight of 200 lbs. To minimize the risk of a tip-over or roll-over, operators weighing more than 200 lbs. should further limit the ground speed and the degree of slope to be mowed.

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.

7. Keep people and pets out of mowing area. Immediately STOP blades, STOP engine, and STOP machine if anyone enters the area.

8. Check shields, deflectors, switches, blade controls and other safety devices frequently for proper operation and location.

9. Make sure all safety decals are clearly legible. Replace if damaged.

10. Protect yourself when mowing and wear safety glasses, a dust mask, hearing protection, long pants and substantial footwear.

11. Know how to STOP blades and engine quickly in preparation for emergencies.

12. Use extra care when loading or unloading the machine into a trailer or truck.

13. Check grass catcher components frequently for signs of wear or deterioration and replace as needed to prevent injury from thrown objects going through weak or worn spots.

Safe Handling of Gasoline

To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

1. Extinguish all cigarettes, cigars, pipes and other sources of ignition.

2. Use only an approved fuel container.

3. DO NOT remove fuel cap or add fuel with the engine running. Allow the engine to cool before refueling.

4. DO NOT refuel the machine indoors.

5. DO NOT store the machine or fuel container inside where there is an open flame, spark or pilot light such as on a water heater or other appliances.

How To Inspect The Mower Blade

WARNING

Wear heavy leather gloves when handling or working around cutting blades. Blades are extremely sharp and can cause severe injury. DO NOT use a cutting blade that shows signs of excessive wear or damage.

Inspect the blade frequently for signs of excessive wear or damage (Figure 27):

(A) New blade; (B) Wear limit (notch starts); (C) Dangerous condition - do not use on mower! Replace

with new blade. Contact your authorized dealer.

Fuel System

Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use

Briggs & Stratton Advanced Formula Fuel Treatment & Stabilizer, available wherever Briggs & Stratton genuine

service parts are sold. There is no need to drain gasoline from the engine if a fuel

stabilizer is added according to instructions. Run the engine for two (2) minutes to circulate the stabilizer throughout the fuel system before storage.

If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into an approved container. Run the engine until it stops from lack of fuel. The use of a fuel stabilizer in the storage container is recommended to maintain freshness.
