Never operate the Power Unit or Implement until you have read

and completely understand this Manual, the Power Unit Operators

Manual, and each of the Safety Messages found in the Manual or

on the Power Unit and Implement. Learn how to stop the Power

Unit engine suddenly in an emergency. Never allow inexperienced

or untrained personnel too operate the Power Unit and Implement

without supervision. Make sure the operator has fully read and

understood the manuals prior to operation.

Always maintain the safety decals in good readable condition. If

the decals are missing, damaged, or unreadable, obtain and install

replacement decals immediately.

Make certain that the Slow Moving Vehicle (SMV) sign is installed in such a way as to be clearly

visible and legible. When transporting the Equipment use the Power Unit flashing warning lights and

follow all local traffic regulations.

Operate this Equipment only with a Tractor equipped with an

approved roll-over-protective system (ROPS). Always wear seat

belts. Serious injury or even death could result from falling off the

tractorparticularly during a turnover when the operator could be

pinned under the Operator Protective Structure.

Do not modify or alter this Implement. Do not permit anyone to

modify or alter this Implement, any of its components or any

Implement function.

BEFORE leaving the Power Unit seat, always engage the brake and/or set the Power Unit transmission

in parking gear, disengage the auxiliary hydraulics, stop the engine, remove the key, and wait for all

moving parts to stop. Place the Power Unit shift lever into a low range or parking gear to prevent the

tractor from rolling. Never dismount a Power Unit that is moving or while the engine is running. Operate

the Power Unit controls from the operator seat only.

F3788-7-04 Safety Section 1-4

SAFETY

Never allow children to operate or ride on the Power Unit or Implement.

Do not mount the Power Unit while the Power Unit is moving. Mount the

Power Unit only when the Power Unit and all moving parts are completely

stopped.

Start the Power Unit only when properly seated in the Power Unit seat.

Starting a Power Unit in gear can result in injury or death. Read the Power

Unit operator's manual for proper starting instructions.

Never work under the Implement, the framework, or any lifted component

unless the Implement is securely supported or blocked up to prevent

sudden or inadvertent falling which could cause serious injury or even

death.

The operator and all support personnel should wear hard hats, safety

shoes, safety glasses, and proper hearing protection at all times for

protection from injury including injury from items thrown by the

equipment.

PROLONGED EXPOSURE TO LOUD NOISE MAY CAUSE

PERMANENT HEARING LOSS!

Tractors with or without an Implement

attached can often be noisy enough to cause permanent hearing loss.

We recommend that you always wear hearing protection if the noise in

the Operators position exceeds 80db. Noise over 85db over an extended

period of time will cause severe hearing loss. Noise over 90db adjacent to

the Operator over an extended period of time will cause permanent or

total hearing loss.

Note: Hearing loss from loud noise [from tractors, chain

saws, radios, and other such sources close to the ear] is cumulative over

a lifetime without hope of natural recovery

SAFETY

Do not operate this Equipment with hydraulic oil leaking. Oil is expensive

and its presence could present a hazard. Do not check for leaks with your

hand! Use a piece of heavy paper or cardboard. High- pressure oil streams

from breaks in the line could penetrate the skin and cause tissue damage

including gangrene. If oil does penetrate the skin, have the injury treated

immediately by a physician knowledgeable and skilled in this procedure.

Transport only at safe speeds. Serious accidents and injuries can result

from operating this equipment at unsafe speeds. Understand the Power

Unit and Implement and how it handles before transporting on streets and

highways. Make sure the Power Unit steering and brakes are in good

condition and operate properly.

Before transporting the Power Unit and Implement, determine the safe

transport speeds for you and the equipment. Make sure you abide by the

following rules:

1. Test the Power Unit at a slow speed and increase the speed slowly.

Apply the Brakes smoothly to determine the stopping characteristics of

the Power Unit and Implement.

As you increase the speed of the Power Unit the stopping distance

increases. Determine the maximum safe transport speed for you and

this Equipment.

2. Test the equipment at a slow speed in turns. Increase the speed

through the turn only after you determine that it is safe to operate at a

higher speed. Use extreme care and reduce your speed when turning

sharply to prevent the Power Unit and Implement from turning over.

Determine the maximum safe turning speed for you and this equipment

before operating on roads or uneven ground.

3. Only transport the Power Unit and Implement at the speeds that you

have determined are safe and which allow you to properly control the

equipment.

Be aware of the operating conditions. Do not operate the Power Unit with

weak or faulty brakes. When operating down a hill or on wet or rain slick

roads, the braking distance increases: Use extreme care and reduce your

speed. When operating in traffic always use the Power Unit's flashing

warning lights and reduce your speed. Be aware of the traffic around you

and watch out for the other guy.

Never attempt to lubricate, adjust, or remove material from the Implement

while it is in motion or while Power Unit engine is running. Make sure the

Power Unit engine is off before working on the Implement!

Periodically inspect all moving parts for wear and replace when necessary

with authorized service parts. Look for loose fasteners, worn or broken

parts, and leaky or loose fittings. Make sure all pins have cotter pins and

washers. Serious injury may occur from not maintaining this machine in

good working order.
