Safe Operation Practices

en

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 mower. 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 respon-

sible 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:

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.

For Ride-On (Riding) Rotary Mower

Machines

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. W

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 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.

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 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;

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, un-

less 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.

c. Do not turn sharply. Use care when reversing.

d. Use counterweight(s) or wheel weights when

suggested in the Instruction Book.

7. Watch out for traffic when crossing or near

roadways.

8. Stop the blades rotating before crossing surfaces

other than grass.

Maintenance Free Battery

IMPORTANT: Before you attach the battery cables to

the battery, check the battery date. The battery date

tells if the battery must be charged.

1. Check the top of the battery (1) for the location of

the battery date (see F

Figure 4

).

2. If the battery is put into service before the

battery cables can be attached without charging

the battery. See “Install the Battery Cables.”

3. If the battery is put into service after the battery

must be charged. See “Charge the Battery.”

Charge the Battery

WARNING

When you charge the battery, do not smoke. Keep

the battery away from any sparks. The fumes from

the battery acid can cause an explosion.

1. Remove the battery (1) and battery tray (3) (see

Figure 4

).

2. Remove the protective caps from the battery

terminals.

3. Use a 12 volt battery charger to charge the battery.

3. Fasten the black cable (8) to the negative (-)

terminal with the fasteners (6) and (7).

Check the Tires

Check the air pressure in the tires. Tires with too much

air pressure will cause the unit to ride rough. Also, the

wrong air pressure will keep the mower housing from

cutting level. The correct air pressure is: Front Tires

0,97 BAR (14 PSI), Rear Tires 0,69 BAR (10 PSI). The

tires were over inflated for shipment.

Check the Level of the Mower Housing

Make sure the level of cut is still correct. After you mow

a short distance, look at the area that was cut. If the

mower housing does not cut level, see the instructions

to “Level the Mower Housing” in the Maintenance sec-

tion of this instruction book.

Prepare the Engine

NOTE: The engine was shipped from the factory filled

with oil. Check the level of the oil. Add oil as needed.

See the engine manufacturer’s instructions for the type

of petrol and oil to use. Before you use the unit, read

the information on safety, operation, maintenance, and

storage.

WARNING

Follow the engine manufacturer’s instructions for

the type of petrol and oil to use. Always use a safety

petrol container. Do not smoke when adding petrol

Operation

en

Start the Engine

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 object.

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.

WARNING

The electrical system has an operator presence

system that includes a sensor switch for the seat.

These components tell the electrical system if the

operator is sitting on the seat. This system will stop

the engine when the operator leaves the seat. For

your protection, always make sure this system

operates correctly.

NOTE: The engine will not start unless you depress the

clutch/brake pedal and move the blade rotation control

to the DISENGAGE position.

1. Push the clutch/brake pedal completely forward.

Keep your foot on the pedal.

2. Move the shift lever to the neutral (N) position.

3. Make sure the blade rotation control is in the

DISENGAGE position.

4. Move the throttle control completely forward to the

CHOKE or FAST position. Some models have a

separate choke knob. Pull the choke knob to the

full CHOKE position.

5. Turn the ignition key to the START position.

NOTE: If the engine does not start after four or five

tries, move the throttle control to the FAST position.

Again try to start the engine. If the engine will not start,

see the TROUBLESHOOTING CHART.

6. Slowly move the throttle control to the SLOW

position.

7. To start a hot engine, move the throttle control to a

position between FAST and SLOW.

Mowing and Bagging Tips

General Recommendations

1. The owner’s responsibility is to maintain this

product. This will extend the life of the product

and is also necessary to maintain warranty

coverage.

2. Check the spark plug, drive brake, lubricate the

unit, and clean the air filter once a year.

3. Check the fasteners. Make sure all fasteners are

tight.

4. Follow the Maintenance section to keep the unit in

good operating condition.

WARNING

Before you make an inspection, adjustment, or

repair to the unit, disconnect the wire to the spark

plug. Remove the wire from the spark plug to

prevent the engine from starting by accident.

NOTE: Torque is measured in foot pounds (metric Nm).

This measurement describes how tight a nut or bolt

must be.The torque is measured with a torque wrench.

Inspect the Blade

WARNING

Before you inspect or remove the blade, disconnect

the wire to the spark plug. If the blade hits an

object, stop the engine. Check the unit for damage.

The blade has sharp edges.When you hold the

blade, use gloves or cloth material to protect your

hands.

If you keep the blade (1) sharp and inspect the blade

for damage, the blade will cut better and be more safe

to operate (see F

Figure 7

). Frequently check the blade

for excessive wear, cracks,or other damage.

Frequently check the nut (3) that holds the blade (1).

Keep the nut (3) tight. If the blade hits an object, stop

the engine. Disconnect the wire to the spark plug. See

if the blade is bent or damaged. Check the blade

adapter (5) for damage.

Before you operate the unit, replace damaged parts

with original equipment parts. See the authorized serv-

ice center in your area. Every three years, have an au-

thorized service person inspect the blade or replace

the old blade with an original equipment part.

Remove and Install the Blade

1. Remove the mower housing. See the instructions

to “Remove the Mower Housing.”

2. Use a piece of wood to keep the blade from

rotating.

3. Remove the nut (3) that holds the blade (1) (see

Figure 7

).

4. Check the blade and the blade adapter (5)

according to the instructions for “Inspect Blade.”

Replace a badly worn or damaged blade with an

original equipment blade. See an authorized

service center in your area.

5. Clean the top and bottom of the mower housing.

Remove all the grass and debris.

6. Mount the blade and blade adapter (5) on the

mandrel (6).

7. Mount the blade so that the hi-lift edges (7) are

up. If the blade is upside down, the blade will not

cut correctly and can cause an accident.

8. Fasten the blade with the original washers and

nut (3). Make sure the outside rim of the Belleville

washer (2) is against the blade.

WARNING

Always keep the nut (3) tight that holds the blade

(1). A loose nut or blade can cause an accident.

9. Tighten the nut (3) that holds the blade to 30 ft-lbs

(41,5 Nm).

10. Install the mower housing. See “Remove the

Mower Housing.”

Adjust the Blade Rotation Control

WARNING

To prevent an injury, the blade rotation control must

operate correctly.

In normal usage, the blade rotation control will not re-

quire an adjustment. However, it the cutting perform-

ance decreases or the quality of cut is poor, make the

following changes.

1. When you mow, make sure the throttle control is in

the FAST position.

2. Move the blade rotation control to the DIS-

ENGAGE position (1) (see F

Figure 8

).

3. Stop the engine. Disconnect the wire from the

spark plug.

4. Check the blade(s). Keep a sharp edge on the

blade(s). A blade that is not sharp will cause the

tips of the grass to become brown.

5. Disconnect the blade drive spring (2) from the

blade control rod (1) (see F

Figure 9

). Move the

blade drive spring (2) to the middle hole (4). This

will increase the tension on the mower drive belt.

6. Attach the wire to the spark plug. Mow for a short

distance and again check the quality of cut. If

necessary, move the blade drive spring (2) to the

bottom hole (5).

7. Again check the quality of cut. If the quality of cut

has not improved, replace the mower drive belt.

See ”Replace the Mower Drive Belt.” If replacing

the belt does not correct the problem, take the unit

to an authorized service center.

8. Move the blade rotation control to the DIS-

ENGAGE position. Stop the engine.

9. Check the operation of the blade brake. Rotate the

pulleys with your hand. Make sure the brake pads

(7) are pressed tightly against the pulleys (see

Figure 10

).

WARNING

If the brake pads (7) do not press tightly against the

pulleys, take the unit to an authorized service

center.

10. Move the blade rotation control to the ENGAGE

position (2) (see F

Figure 8

).

11. Check the pads for the blade brake (7) (see

Figure 10
