2. Never allow children or people unfamiliar with

these instructions to use the mower. Local regulations may restrict the age of the operator.

3. Never mow while people, especially children, or

4. Keep in mind that the operator or user is responsible for accidents or hazards occurring to other

people or their property.

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 vapors have dissipated e. Replace all fuel tanks and container caps securely.

4. Replace faulty silencers.

5. 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.

6. On multi-blade machines, take care as rotating

one blade can cause other blades to rotate.

5. Do not carry passengers.

6. All drivers should seek and obtain professional

and practical instruction. Such instruction should emphasize:

1. Do not operate the engine in a confined space

where dangerous carbon monoxide fumes can collect. 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;

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

1. While mowing, always wear substantial footwear

and long trousers. Do not operate the equipment when barefoot or wearing open sandals.

2. Thoroughly inspect the area where the equipment

will be used and remove all objects which may be thrown by the machine.

3. WARNING-Petrol is highly flammable.

a. Store fuel in containers specifically designed for this purpose.

2. Mow only in daylight or in good artificial light.

3. Before attempting to start the engine, disengage

all blade attachment clutches and shift into neutral.

4. Do not use on slopes of more than 10 degrees.

5. 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;

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.

6. 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.

Do not turn sharply. Use care when reversing. d. Use counterweight(s) or wheel weights when suggested in the Instruction Book. b. Refuel outdoors only and do not smoke while refuelling.

7. Watch out for traffic when crossing or near

8. Stop the blades rotating before crossing surfaces

other than grass. 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.

Safe Operation Practices

9. When using any attachments, never direct

discharge of material toward bystanders nor allow anyone near the machine while in operation.

Figure 9 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 control lever (7) in the FAST position

(see Figure 7). 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

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.

mower housing. See “Level the Mower Housing” in the Maintenance section.

2. For the mower housing to cut level, make sure the

tires have the correct amount of air pressure.

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 near an

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 speed control pedal pushed 1/3 to 1/2 forward.
