WARNING: This cutting machine is

capable of amputating hands and feet and throwing objects. Failure to observe the following safety instructions could result in serious injury or death to the operator or bystanders.

Thoroughly inspect the area where the equipment is to be used and remove all objects which may be thrown by the machine. WARNING -- Petrol is highly flammable. a. Store fuel in containers specifically designed for this purpose. b. Refuel outdoors only and do not smoke while refuelling. c. Add fuel before starting the engine. Never remove the cap of the fuel tank or add petrol while the engine is running or when the engine is hot. d. If petrol is spilled, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until petrol vapours have dissipated. e. Replace all fuel tanks and container caps securely. Replace faulty silencers. Before using, always visually inspect to see that the blades, blade bolts and cutter assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance. On multi--blade machines, take care as rotating one blade can cause other blades to rotate. The responsibility of the owner is to follow the instructions below.

Operation For Ride--On (Riding) Rotary Mower Machines Training

Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. Never allow children or people unfamiliar with these instructions to use the mower. Local regulations may restrict the age of the operator. Never mow while people, especially children, or pets are nearby. Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property. Do not carry passengers. All drivers should seek and obtain professional and practical instruction. Such instruction should emphasize: a. the need for care and concentration when working with ride--on machines; b. control of a ride--on machine sliding on a slope will not be regained by the application of the brake. The main reasons for loss of control are: insufficient wheel grip; being driven too fast; inadequate braking the type of machine is unsuitable for its task; lack of awareness of the effect of ground conditions, especially slopes; incorrect hitching and load distribution. Preparation

While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when barefoot or wearing open sandals.

Do not operate the engine in a confined space where dangerous carbon monoxide fumes can collect. Mow only in daylight or in good artificial light. Before attempting to start the engine, disengage all blade attachment clutches and shift into neutral. Do not use on slopes of more than 10 degrees. Remember there is no such thing as a “safe” slope. Travel on grass slopes requires particular care. To guard against overturning: a. do not stop or start suddenly when going up or downhill; b. engage clutch slowly, always keep machine in gear, especially when travelling downhill; c. machine speeds should be kept low on slopes and during tight turns; d. stay alert for humps and hollows and other hidden hazards; e. never mow across the face of the slope, unless the mower is designed for this purpose. Use care when pulling loads or using heavy equipment. a. Use only approved drawbar hitch points. b. Limit loads to those you can safely control. c. Do not turn sharply. Use care when reversing. d. Use counterweight(s) or wheel weights when suggested in the Instruction Book. Watch out for traffic when crossing or near roadways. Stop the blades rotating before crossing surfaces other than grass. When using any attachments, never direct discharge of material toward bystanders

nor allow anyone near the machine while in operation. Never operate the mower with defective guards or shields, or without safety protective devices in place. Do not change the engine governor settings or overspeed the engine. Operating an engine at excessive speed may increase the hazard of personal injury. Before leaving the operator’s position a. disengage the power take--off and lower the attachments; b. change into neutral and set the parking brake; c. stop the engine and remove the key. Disengage drive to attachments, stop the engine, and disconnect the spark plug wire(s) or remove the ignition key a. before cleaning blockages or unclogging chute; b. before checking, cleaning or working on the mower; c. after striking a foreign object. Inspect the mower for damage and make repairs before restarting and operating the equipment; d. if the machine starts to vibrate abnormally (check immediately). Disengage drive to attachments when transporting or not in use. Stop the engine and disengage drive to attachment a. before refuelling; b. before removing the grass catcher; c. before making height adjustment unless adjustment can be made from the operator’s position. Reduce the throttle setting during engine run--out and, if the engine is provided with a shut--off valve, turn the fuel off at the conclusion of mowing. Before and when backing, look behind and down for small children. Use extra care when approaching blind corners, shrubs, trees or other objects that may obscure vision. Maintenance and Storage

On multi--blade machines, take care as rotating one blade can cause other blades to rotate. When machine is to be parked, stored or left unattended, lower the cutting means unless a positive mechanical lock is used. Keep all nuts, bolts, and screws tight to be sure the equipment is in safe working condition. Never store the equipment with petrol in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure. To reduce the fire hazard, keep the engine, silencer, battery compartment and petrol storage area free of grass, leaves, or excessive grease. Check the grass catcher frequently for wear or deterioration. Replace worn or damaged parts for safety. If the fuel tank has to be drained, this should be done outdoors.

Mowing And Bagging Tips

1. For a lawn to look better, check the cutting

level of the mower housing. See “How To Level The Mower Housing” in the Maintenance section.

2. Check the oil. Follow the procedure in the

engine manufacturer’s instructions.

2. For the mower housing to cut level, make

sure the tyres have the correct amount of air pressure.

3. If necessary, add oil until the oil reaches the

FULL mark on the dipstick. The quantity of oil needed from ADD to FULL is shown on the dipstick. Do not add too much oil.

3. Every time you use the unit, check the blade.

If the blade is bent or damaged, immediately replace the blade. Also, make sure the nut for the blade is tight.

4. Keep the blade(s) sharpened. Worn blades

will cause the ends of the grass to turn brown.

5. Do not cut or bag grass that is wet. Wet

grass will not discharge correctly. Let the grass dry before cutting.

6. Use the left side of the mower housing to trim

7. Discharge the cut grass onto the mowed

area. The result is a more even discharge of cut grass.

8. When you mow large areas, start by turning

to the right so that the cut grass will discharge away from shrubs, fences, driveways, etc. After one or two rounds, mow in the opposite direction making left turns until finished.

9. If the grass is very high, cut two times to decrease the load on the engine. First cut with

the mower housing in the highest position and then lower the mower housing for the second cut.

10. For better engine performance and an even

discharge of the cut grass, always operate the engine with the throttle in FAST position.

11. When you use a bagger, operate the engine

with the throttle in FAST position and the shift lever in first or second gear.

12. For better cutting performance and a quality

cut, mow with the shift lever in one of the slower speeds.

13. After each use, clean the bottom and top of

the mower housing for better performance. Also, a clean mower housing will help prevent a fire. Mulching Tips When you use a mulcher attachment, the grass is cut into very small pieces. These small pieces will quickly break down. Because the nutrients are returned to the soil, the lawn will need less fertilizer. To correctly mulch the grass, follow the steps below.

1. Set the throttle in the FAST position. Operate

the mower at a slower ground speed. If ground speed is too fast, the grass will not have an even cut.

2. Keep a sharp edge on the blade. A blade that

is not sharp will cause the ends of the grass to become brown.

3. Make sure the grass is dry. Wet grass is difficult to cut.

4. Set the height of the mower housing so that

only the top third of the grass is cut. If the grass is too high, set the height of the mower housing to the maximum height. Then, lower the mower housing for the second cut. Also, instead of using the full width of the mower housing, mulch at half the width.

5. Clean the bottom of the mower housing.

Grass and other debris can keep the mower from working correctly.

6. If the grass grows fast, mulch more often.

7. If an area needs improvement, mulch a second time.
