2.3 BEFORE OPERATION

CONSIDERATIONS

1. NEVER allow children to operate this riding mower.

Do not allow adults to operate this machine without

proper instructions.

2. DO NOT mow when children and/or others are

present.

3. Clear the area to be mowed of objects that could be

picked up and thrown by the cutter blades.

4. DO NOT carry passengers.

Section 2

WARNING:

-NOTE-

WARNING:

12. quipment must comply with the latest requirements

per ANSI J137 and/or ANSI S279 when driven on

public roads.

If the mower is driven on public roads, it must

comply with state and local ordinances as well as

SAE J137 and/or A SI / ASAE S279 requirements.

Contact your local authorities for regulations and

equipment requirements.

13. DO NOT operate without a chute deflector installed;

keep the deflector in lowest possible position.

14. Check the blade mounting bolts at frequent intervals

for proper tightness.

15. Make sure all hydraulic fluid connections are tight and

all hydraulic hoses and lines are in good condition

before starting the machine.

2.4 OPERATION CONSIDERATIONS

1. Know the function of all controls and how to stop

quickly.

2. Reduce speed and exercise extreme caution on slopes

and in sharp turns to prevent tipping or loss of control.

Be especially cautious when changing directions on

slopes.

DO NOT operate on steep slopes. To check a slope,

attempt to drive up it (with cutter deck down). If

machine can drive up the slope without the wheels

slipping, reduce speed and use extreme caution.

ALWAYSFOLLOW OSHAAPPROVEDOPERATION.

3. Do not stop or start suddenly. WHEN MOWING A

HILLSIDE, MOW UP AND DOWN THE FACE

OF SLOPES, NEVER ACROSS THE FACE.

4. When using any attachment, never direct the discharge

of material toward bystanders or allow anyone near

the machine while in operation.

5. DO NOT wear loose fitting clothing that could get

tangled in moving parts. Do not operate the machine

wearing shorts; always wear adequate protective

clothing including long pants. Wearing safety glasses,

safety shoes and a helmet is advisable and is required

by some local ordinances and insurance regulations.

6. Operator hearing protection is recommended,

particularly for continuous operation of the mower.

Wear suitable hearing protection. Prolonged exposure

to loud noise can cause hearing impairment or loss.

7. Keep the machine and attachments in good operating

condition. Keep all shields and safety devices in place.

If a shield, safety device or decal is defective or

damaged, repair or replace it before operating the

machine.

This machine is equipped with an interlock system

intended to protect the operator and others from

injury. This is accomplished by preventing the

engine from starting unless the operator is seated

in the seat, the deck drive is disengaged, and the

speed control is placed in the neutral position with

the parking brake applied. The system also shuts

off the engine if the operator leaves the seat with

the mower running and the speed control is not in

the neutral postion with the parking brake applied.

It will also shut off the engine if the hopper is raised

with the cutter deck drive engaged. Never operate

equipment with the interlock system disconnected

or malfunctioning.

8. Be sure interlock switches are functioning correctly.

9. Fuel is flammable; handle with care. Fill fuel tank

outdoors. Never fill indoors. Use a funnel or spout to

inhibit spillage. Clean up any spillage before starting

the engine.

10. DO NOT add fuel to a running or hot engine. An

explosion could occur. Allow engine to cool for several

minutes before adding fuel.

11. Keep flammable objects (cigarettes, matches, etc.),

open flames and sparks away from the fuel tank and

fuel container.

Section 2

5. Before attempting to start the engine, with the

operator in the seat, disengage power to the cutter

deck, place the hopper in the stowed position,

steering control levers in the neutral position and

engage the parking brake.

6. If the mower discharge ever plugs, shut off the

engine, remove the ignition key, and wait for all

movement to stop before removing the obstruction.

Do not use your hand to dislodge the clogged

discharge chute. Use a stick or other device to

remove clogged material.

7. Be alert for holes, rocks, and roots in the terrain and

other hidden hazards. Keep away from any dropoff.

Beware of overhead obstructions such as low limbs,

etc. and underground obstacles such as sprinklers,

pipes, tree roots, etc. Cautiously enter a new area.

Be alert for hidden hazards.

8. Disengage power to cutter deck before backing up.

Do not mow in reverse unless absolutely necessary

and then only after observation of the entire area

behind the mower.

9. DO NOT turn sharply. Use care when backing up.

10. Disengage power to cutter deck before crossing

roads, walks or gravel drives. Watch for traffic when

crossing roads or operating near roadways.

11. Mow only in daylight or good artificial light.

12. Take all possible precautions when leaving the

machine unattended, such as disengaging the mower,

lowering the attachments, setting the parking brake,

stopping the engine, and removing the key.

13. Disengage power to the attachments when

transporting or when not in use.

14. The machine and attachments should be stopped and

inspected for damage after striking a foreign object,

and damage should be repaired before restarting and

operating the machine.

clothing away from moving parts.

2. Remove the key from the ignition switch to prevent

accidental starting of the engine when servicing or

adjusting the machine.

3. Keep all nuts, bolts and screws tight to ensure the

machine is in safe working condition. Check blade

mounting bolts frequently to be sure they are tight.

4. Do not change the engine governor settings or

overspeed the engine. See the engine operator's

manual for information on engine settings.

5. To reduce fire hazard, keep the engine free of grass,

leaves, excessive grease and dirt.

6. Hydraulic fluid i under high pre ure. Keep

body and hands away from pinholes or nozzles that

eject hydraulic fluid under high pressure. Use only

cardboard or paper to search for leaks. If you need

service on your hydraulic system, please see your

authorized Scag dealer.

sufficient force to penetrate skin and cause serious

injury. If hydraulic fluid is injected into the skin, it

must be surgically removed within a few hours by a

doctor or gangrene may result.
