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 and turn machine OFF if anyone enters the area.
3.DO NOT allow pre-teenage children to operate machine.
4.ALLOW only responsible adults & teenagers with mature judgment under close adult supervision to operate machine.
5.DO NOT pull mower backwards unless absolutely necessary. LOOK and SEE behind and down for children, pets and hazards before and while backing.
6.USE EXTRA CARE when approaching blind corners, shrubs, trees, or other objects that may obscure vision.
SLOPE OPERATION
1.Slopes are a major factor related to slip and fall accidents, which can result in severe injury. All slopes require extra caution. If you feel uneasy on a slope, DO NOT mow it.
2.Mow across slopes, never up-and-down. Exercise extreme CAUTION when changing directions on slopes. DO NOT mow steep slopes or other areas where stability or traction is in doubt.
3.Use extra care with crass catchers or other attachments; these affect the handling and the stability of the machine.
PREPARATION
1.Read, understand, and follow instructions and warnings in this manual and on the mower, engine and attachments. Know the controls and the proper use of the mower before starting.
2.Only mature, responsible persons shall operate the machine and only after proper instruction.
PREPARATION
(Continued From Previous Column)
3.Data indicates that operators age 60 and above, are involved in a large percentage of mowerrelated 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 and oil from machine. DO NOT smoke.
5.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. Also note the location of holes, stumps, and other possible hazards.
6.Keep people and pets out of the mowing area. Immediately, STOP Blade, Stop engine and Stop mower if anyone enters the area.
7.Check shields, deflectors, switches, blade controls and other safety devices frequently for proper operation and location.
8.Make sure all safety decals are clearly legible. Replace if damaged.
9.Protect yourself when mowing and wear safety glasses, long pants and substantial footwear. DO NOT mow barefooted or with sandals.
10.Know how to STOP blade and engine quickly in preparation for emergencies.
11.Use extra care when loading or unloading the machine into a trailer or truck.
12.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 torn spots.

Section 2 - OPERATING INSTRUCTIONS
WARNING
DO NOT attempt any maintenance, adjustments or service with engine and blade running. STOP engine and blade. Disconnect spark plug wire and secure away from spark plug. Engine and components are HOT. Avoid serious burns, allow sufficient time for all components to cool.
2.6 RECYCLING OPERATION
NOTE: For best recycling results, cut up to a maximum of 1/3 of grass blade length and recycle ONLY when grass is dry.
1.Set all wheels in the highest cutting position (Notch 6).
2.Move engine speed control to “FAST” (Rabbit) position.
3.Move ground speed control to slowest speed setting.
4.Proceed mowing slowly. If grass is very dense, lower each rear wheel latch one notch lower than the front wheel latches to improve recycling performance.
2.7ADJUSTING FRONT DECK BAFFLE
(Models with an “F” prefix in model number) (Example: FR215012)
The front of the cutting deck on these models has been modified with an open area. This allows the blade to have more direct contact with the grass and allows more air flow into deck chamber. The adjustable baffle should be secured in the lowest position when using a grass bag. The baffle should be secured in the highest position when mulching grass.
NOTE: Under certain conditions, when mulching, some grass may blow out from under front of baffle. This is normal but, the amount of grass blowing out can be reduced. Lower baffle slightly to reduce the amount of grass blow out.
1.Stop engine.
2.Loosen wing nuts that secure front deck baffle. See Figure 2.8.
3.Lower the adjustable baffle to the lowest position when using a grass bag. Raise the baffle to its highest position when mulching grass. Take care to keep the baffle’s lower edge parallel to the bottom of the deck. See Figure 2.8.
4.Retighten wing nuts securely.
2.8INSTALLATION of GRASS CATCHER
Install grass catcher by sliding connector over flange of adapter. See Figure 2.9. Attach grass bag hooks over middle handle cross bar. See Figure 2.10.
