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. 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.

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

the 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

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. Maintenance Chart Frequency Daily or before each use

2. Disconnect the red cable (5) from the positive (+)

terminal (4). If the mower housing is level, the blade will cut easier and the lawn will look better. WARNING Before you make an inspection, adjustment, or repair to the unit, disconnect the wire to the spark plug. Remove the spark plug wire to prevent the engine from starting by accident.

1. Make sure the unit is on a hard flat surface.

2. Check the air pressure in the tires. If the air

pressure is incorrect, the mower housing will not cut level. Make sure the tires are inflated to: Front Tires 0,97 BAR (14 PSI), Rear Tires 0,69 BAR (10 PSI).

3. Move the lift lever (1) to the lowest cut position (2)

(see Figure 13). WARNING The lifter lever (3) is spring loaded. Make sure the lift lever (3) is locked in the lowest cut position (2).
