SAFE OPERATION 1

A

SAFE

OPERATION

Careful operation is your best insurance against an

accident. Read this section carefully before operating the

mower and the grass catcher.

All operators, no matter

how much experience they may have had,

should read

this

manual, the mower manual, the machine manual, and

other related manuals before operating the mower and

the grass catcher.

It is the owner's obligation to instruct all

operators

in

safe operation.

1. BEFORE OPERATING

• Operator

1.

Allow only a properly trained person to operate the

machine.

2.

Do not operate the machine while under the influence

of

alcohol, medication, other substances or while

fatigued.

3.

Be thoroughly familiar with the controls and learn how

to stop

quickly

in

an

emergency. Know your equipment

and its

limitations.

4. Do not wear loose, torn, or bulky clothing around

machine. The clothing may catch

on

moving parts or

controls, leading to the risk of accident.

Wear and use any

additional safety items such as hard

hat, safety boots or shoes, eye and hearing protection,

gloves, etc., as appropriate or required.

5.

Never allow children to operate the mower and the

grass catcher, even under

adult supervision.

6.

Do not ride on or put anything

on

any grass catcher

component.

• Machine, blades and equipment

1.

Never operate the mower without proper guards,

shields, and all grass catcher components or

discharge deflector

in

place.

2.

The mower and the grass catcher are equipped with

many safety devices.

Do not

alter or remove any part of safety system for

you r safety.

3.

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

mower is

in

safe working condition.

4.

Inspect the impeller for wear and damage. The

impeller that

is

worn out, bent, cracked or otherwise

damaged must be

replaced.

5.

Replace damaged or illegible safety labels.

See

the following page for required labels.

6.

Make sure the machine is counterweighted as

recommended by this

manual. Weights provide the

necessary

balance to prevent tip-over or loss of

traction or steering.

• Working area

1.

Thoroughly inspect the area where the mower and the

grass catcher are to be used.

Remove

all stones, sticks, wires, bones and other

objects that

could be thrown at high speed.

2.

Keep the area of operation clear of all persons,

particularly small children, and pets.

All people and pets should

be

kept at a safe distance

from the work area.

2. OPERATING

• Starting

1.

Never start engine or operate levers from anywhere

other than the seat.

2.

Before starting the engine make sure that the motion

control levers are

in

neutral lock, the parking brake

is

applied, and Power Take Off (PTO)

is

disengaged

(OFF).

• Operation

1.

Keep bystanders at a safe distance from the machine

during mowing operations.

2.

Do not allow passengers, children or non-qualified

operators

on

the machine / mower / grass catcher at

any time. The operator must remain

in

the machine

seat throughout operation.

3.

While making turns

in

rough terrain, reduce machine

speed.

4. Do not mow

while

in

reverse unless absolutely

necessary and then only after inspecting the entire

area behind the mower and the grass catcher.

Be extra

careful

of

children.

5.

Upon striking a foreign object, stop and inspect the

machine, the mower and the grass catcher for

damage. Repair the damage before resuming

operation.

6.

If the grass catcher chute becomes clogged, stop the

machine; disengage the mower drive; shut off the

engine and remove the key, and clean out the chute

before continuing.

7.

Hillside operation is dangerous and is not

recommended.

If it is necessary to use the grass

catcher

on

a hillside, use extreme caution. To avoid

tipping over, operate across

slopes, not up and down.

8.

Do not use the grass catcher on steep inclines, rough

terrain or near drop-offs.

9.

Do not mow on wet grass. Reducing traction could

cause sliding and loss of control.

10.

Do not park the machine on dry grass or leaves.

2 .SAFE OPERATION

3.

MAINTENANCE AND STORAGE

1.

Never attempt to make adjustments or repairs of any

kind

while the machine

and

the mower are running.

Shut off the engine, remove the

key,

set the parking

brake and

allow the blades

and

the impeller to stop.

2.

To reduce fire hazards, clean the machine thoroughly

before storage. Dry grass

and

leaves around the

engine

and

the muffler may ignite.

3.

Moisture content

in

most grasses

can

damage the

mower

and

the grass catcher if these components are

not

properly cleaned after use. Also, dry grass

and

leaves left

in

the container

can

be

a fire hazard.

Always make sure the container

and

the duct are clean

and

completely empty before storage.

4.

The cloth grass bags are subject to wear

and

deterioration. Check them frequently. Use only

genuine replacement bags from KUBOTA.
