SAFETY PRECAUTIONS

Careful operation is your best insurance against an accident. Read this section carefully before operating the vehicle

and accessory. This accessory is capable of amputating hands and feet and throwing objects. Failure to observe the

following safety instructions could result in serious injury. All operators, no matter how experienced they may be,

should read this and other manuals related to the vehicle and accessory before operating. It is the owner's legal

obligation to instruct all operators in safe operation of the accessory.

GLOSSARY:

In this manual, right and left sides are determined by

sitting on the seat of the vehicle facing forward.

In this manual, "accessories" means attachments

(snowblower, rotary broom, blade etc.) that you install

on the vehicle (lawn tractors, A.T.V. s etc).

TRAINING:

This symbol, "Safety Alert Symbol", is used

throughout this manual and on the accessory’s

safety labels to warn of the possibility of serious

injury. Please take special care in reading and

understanding the safety precautions before

operating the vehicle and accessory.

1. Read this owner's manual carefully. Be thoroughly

familiar with the controls and proper use of the

vehicle and accessory. Know how to stop the unit

and disengage the controls quickly.

2. Never allow children to operate the vehicle nor the

accessory. Never allow adults to operate the vehicle

nor the accessory without proper instructions.

3. No one should operate the vehicle nor the

accessory while intoxicated or while taking

medication that impairs the senses or reactions.

4. Keep the area of operation clear of all people,

particularly small children and pets.

PREPARATION:

1. Thoroughly inspect the area where the accessory

is to be used and remove door mats, all foreign

objects and the like.

2. For motorized accessories, disengage all clutches

and shift into neutral before starting engine.

3. Do not operate the accessory without wearing

adequate winter outer garments. Avoid loose fitting

clothing that can get caught in moving parts. Wear

footwear that will improve footing on slippery

surfaces.

4. Handle fuel with care, it is highly flammable.

a) Use approved fuel container.

b) Never add fuel to a running engine or hot engine.

c) Fill fuel tank outdoors with extreme care. Never fill

fuel tank indoors.

d) Never fill containers inside a vehicle, or on a

truck or a trailer bed with a plastic liner. Always

place containers on the ground, away from your

vehicle, before filling.

e) When practical, remove gas-powered

equipment from the truck or trailer and refuel it

on the ground. If this is not possible, then refuel

such equipment on a trailer with a portable

container, rather than from a gasoline

dispenser nozzle.

f) Keep the nozzle in contact with the rim of the

fuel tank or container opening at all times, until

refueling is complete. Do not use a nozzle lock-

open device.

g) Replace fuel cap securely and wipe up spilled

fuel.

h) If fuel is spilled on clothing, change clothing

immediately.

5. Never attempt to make any adjustments while the

engine (motor) is running (except when specifically

recommended by manufacturer).

6. Let the vehicle and accessory adjust to outdoor

temperatures before starting to clear snow.

7. Always wear safety glasses or eye shields during

operation or while performing an adjustment or

repairs to protect the eyes from foreign objects that

may be thrown from the accessory.

8. Never modify the accessory or any part without

the written consent from the manufacturer.

SAFETY PRECAUTIONS

OPERATION:

1. Do not put hands or feet near, under or inside

rotating parts.

2. Exercise extreme caution when operating on or

crossing gravel drives, walks or roads. Stay alert for

hidden hazards or traffic. Do not carry passengers.

3. After striking a foreign object, stop the engine

(motor), disconnect the wire from the spark plug(s)

and keep wire away to prevent accidental starting.

Thoroughly inspect the accessory for any damage

and repair damage before restarting and using the

accessory.

4. If the unit should start to vibrate abnormally, stop

the engine (motor) and check immediately for the

cause. Vibration is generally a warning of trouble.

5. Take all possible precautions when leaving the

vehicle unattended. Disengage the power take-off,

lower the attachment, place the transmission into

neutral, set the parking brake, stop the engine and

remove the contact key.

6. Do not run the engine indoors, except when

starting the engine and for transporting in or out of

the building. Do not operate or let motor run in a

storage area without ventilation because gas

contains carbon monoxide which is odorless,

colorless and can cause death.

7. Never clean across the face of slopes, go from top

to bottom. Exercise extreme caution when using

equipment on slopes. Do not attempt to clear a

steep slope.

8. Never use an accessory without proper guards,

plates, or other safety protective devices in place
