FOREWORD

FOREWORD

The 72” cutting deck has advanced concepts in engineering, design and safety; and if maintained prop­erly, will give excellent service.

Certain information in this manual is emphasized. DANGER, WARNING and CAUTION identify per­sonal safety related information. IMPORTANT identifies mechanical information demanding special
attention. Be sure to read this directive because it deals with the possibility of damaging a part or parts
of the machine. NOTE identifies general information worthy of special attention.

Training

1. Read the instructions carefully. Be familiar with the

controls and the proper use of the equipment.

2. Never allow children or people unfamiliar with these

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

3. Never mow while people, especially children, or

pets are nearby.

4. Keep in mind that the operator or user is responsible

for accidents or hazards occurring to other people or
their property.

5. Do not carry passengers.

6. All drivers should seek and obtain professional and

practical instruction. Such instruction should empha­size:

• the need for care and concentration when work­ing with ride-on machines;

• 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 effects of ground

conditions, especially slopes;

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 is

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

3. WARNING—Petrol is highly flammable.

• Store fuel in containers specifically designed for
this purpose.

• Refuel outdoors only and do not smoke while
refueling.

• 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.

• If petrol is spilled, do not attempt to start the
engine but move the machine away from the are
of spillage and avoid creating any source of igni­tion until petrol vapors have dissipated.

• 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-bladed machines, take care as rotating one

blade can cause other blades to rotate.

Operation

1. Do not operate the engine in a confined space where

dangerous carbon monoxide fumes can collect.

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:

• Never mow side hills over 5°

• Never mow uphill over 10°

• Never mow downhill over 15°

5. Remember there is no such thing as a “safe” slope.

Safety

4

Travel on grass slopes requires particular care. To
guard against overturning:

• do not stop or start suddenly when going up or
downhill;

• engage clutch slowly, always keep machine in
gear, especially when travailing downhill;

• machine speeds should be kept low on slopes and
during tight turns;

• stay alert for bumps and hollows and other hid­den hazards;

• never mow across the face of the slope, unless
the lawnmower is designed for this purpose.

6. Use care when pulling loads or using heavy equip-

ment.

• Use only approved drawbar hitch points.

• Limit loads to those you can safely control.

• Do not turn sharply. Use care when reversing.

• Use counterweight(s) or wheel weights when
suggested in the instruction handbook .

7. Watch out for traffic when crossing or near road-

ways.

8. Stop the blades rotating before crossing surfaces

other than grass.

9. When using any attachments, never direct discharge

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

10. Never operate the lawnmower with defective guards,

shields or without safety protective devices in place.

11. Do not change the engine governor settings or over-

speed the engine. Operating the engine at excessive
speeds may increase the hazard of personal injury.

12. Before leaving the operator's position:

• disengage the power take-off and lower the
attachments;

• change into neutral and set the parking brake;

• stop the engine and remove the key.

13. Disengage drive to attachments, stop the engine, and

disconnect the spark plug wire(s)or remove the igni­tion key

• before cleaning blockages or unclogging chute;

• before checking, cleaning or working on the
lawnmower;

• after striking a foreign object. Inspect the lawn­mower for damage and make repairs before
restarting and operating the equipment;

• if the machine starts to vibrate abnormally (check
immediately).

14. Disengage drive to attachments when transporting or

not in use.

15. Stop the engine and disengage drive to attachment

• before refueling;

• before removing the grass catcher;

• before making height adjustment unless adjust­ment can be made from the operator's position.

16. Reduce the throttle setting during engine runout and,

if the engine is provided with a shutoff valve, turn
the fuel off at the conclusion of mowing.

Maintenance and Storage

1. Keep all nuts, bolts and screws tight to be sure the

equipment is in safe working condition.

2. Never store the equipment with petrol in the tank

inside a building where fumes may reach an open
flame or spark.

3. Allow the engine to cool before storing in any enclo-

sure.

4. To reduce the fire hazard, keep the engine, silencer,

battery compartment and petrol storage area free of
grass, leaves, or excessive grease.

5. Check the grass catcher frequently for wear or dete-

rioration.

6. Replace worn or damaged parts for safety.

5

7. If the fuel tank has to be drained, this should be

done outdoors

8. On multi-bladed machines, take care as rotating one

blade can cause other blades to rotate.

9. When machine is to be parked, stored or left unat-

tended, lower the cutting means unless a positive
mechanical lock is used.
