General Information

WARNING

Some illustrations in this manual show the equipment with safety shields removed to provide a better view. This

equipment should never be operated with any necessary safety shielding removed.

The purpose of this manual is to assist you in operating and maintaining your 3-point equipment. Read it carefully. It furnishes

information and instructions that will help you achieve years of dependable performance. These instructions have been

compiled from extensive field experience and engineering data. Some information may be general in nature due to unknown

and varying operating conditions. However, through experience and these instructions, you should be able to develop

procedures suitable to your particular situation.

The illustrations and data used in this manual were current at the time of printing but, due to possible inline production

changes, your machine may vary slightly in detail. We reserve the right to redesign and change the machines as may be

necessary without notification.

Throughout this manual, references are made to right and left directions. These are determined by standing behind the

equipment, facing the direction of the forward travel.

SAFETY RULES

Safety Rules

ATTENTION! Become alert! Your safety is involved!

Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide

safe equipment can be wiped out by an operator’s single careless act. In addition to the design and configuration

of equipment, hazard control and accident prevention are dependent upon the awareness, concern, judgment, and

proper training of personnel involved in the operation, transport, maintenance and storage of equipment. It has

been said “The best safety device is an informed, careful operator.” We ask you to be that kind of operator.

Training

• Safety instructions are important! Read all attachment and power unit manuals; follow all safety rules and safety

decal information. (Replacement manuals and safety decals are available from your dealer. To locate your nearest

dealer, check the Dealer Locator at OregonProducts.com, or in the United States and Canada call 1-800-525-8322.)

Failure to follow instructions or safety rules can result in serious injury or death.

• If you do not understand any part of this manual and need assistance, see your dealer.

• Know your controls and how to stop engine and attachment quickly in an emergency.

• Operators must be instructed in and be capable of the safe operation of the equipment, its attachments, and all

controls. Do not allow anyone to operate this equipment without proper instructions.

• Never allow children or untrained persons to operate equipment.

Preparation

• Check that all hardware is properly installed. Always tighten to torque chart specifications unless instructed otherwise

in this manual.

• Always wear relatively tight and belted clothing to avoid getting caught in moving parts. Wear sturdy, rough-soled

work shoes and protective equipment for eyes, hair, hands, hearing, and head; and respirator or filter mask where

appropriate.

• Make sure attachment is properly secured, adjusted, and in good operating condition.

• Make sure spring-activated locking pin or collar slides freely and is seated firmly in tractor PTO spline groove.

• Before putting equipment into service, check and adjust driveline length as instructed in Operator's Manual. Driveline

must not bottom out or pull apart throughout the full range of the tractor hitch. Do not operate until driveline length is

correct.

• Before starting power unit, check all equipment driveline guards for damage. Replace any damaged guards. Make

sure all guards rotate freely on all drivelines. If guards do not rotate freely on drivelines, repair and replace bearings

before putting equipment into service.

• Power unit must be equipped with ROPS or ROPS cab and seat belt. Keep seat belt securely fastened. Falling off

power unit can result in death from being run over or crushed. Keep foldable ROPS systems in “locked up” position at

all times.

• Remove accumulated debris from this equipment, power unit, and engine to avoid fire hazard.

• Make sure all safety decals are installed. Replace if damaged. (See Safety Decals section for location.)

• Make sure shields and guards are properly installed and in good condition. Replace if damaged.

SAFETY RULES

• A minimum 20% of tractor and equipment weight must be on the tractor front wheels when attachments are in

transport position. Without this weight, front tractor wheels could raise up resulting in loss of steering. The weight

may be attained with front wheel weights, ballast in tires, front tractor weights or front loader. Weigh the tractor and

equipment. Do not estimate.

• Inspect and clear area of stones, branches, or other hard objects that might be thrown, causing injury or damage.

Operation

• Only engage power when equipment is at ground operating level. Always disengage power when equipment is raised

off the ground.

• Do not allow bystanders in the area when operating, attaching, removing, assembling, or servicing equipment.

• Keep bystanders away from equipment.

• Never direct discharge toward people, animals, or property.

• Do not operate equipment while under the influence of alcohol or drugs.

• Operate only in daylight or good artificial light.

• Keep hands, feet, hair, and clothing away from equipment while engine is running. Stay clear of all moving parts.

• Always comply with all state and local lighting and marking requirements.

• Never allow riders on power unit or attachment.

• Power unit must be equipped with ROPS or ROPS cab and seat belt. Keep seat belt securely fastened. Falling off

power unit can result in death from being run over or crushed. Keep foldable ROPS systems in “locked up” position at

all times.

• Always sit in power unit seat when operating controls or starting engine. Securely fasten seat belt, place transmission

in neutral, engage brake, and ensure all other controls are disengaged before starting power unit engine.

• Operate tractor PTO at 540 RPM. Do not exceed.

• Do not operate PTO during transport.

• Connect PTO driveline directly to power unit PTO shaft. Never use adapter sleeves or adapter shafts. Adapters can

cause driveline failures due to incorrect spline or incorrect operating length and can result in personal injury or death.

• Look down and to the rear and make sure area is clear before traveling in reverse.

• Use extreme care when working close to fences, ditches, other obstructions, or on hillsides.

• Do not operate or transport on steep slopes.

• Do not stop, start, or change directions suddenly on slopes.

• Use extreme care and reduce ground speed on slopes and rough terrain.

• Watch for hidden hazards on the terrain during operation.

• Stop power unit and equipment immediately upon striking an obstruction. Turn off engine, remove key, inspect, and

repair any damage before resuming operation.

• Before performing any service or maintenance, disconnect driveline from tractor PTO.

• Before dismounting power unit or performing any service or maintenance, follow these steps: disengage power to

equipment, lower the 3-point hitch and all raised components to the ground, operate valve levers to release any

hydraulic pressure, set parking brake, stop engine, remove key, and unfasten seat belt.

SAFETY RULES

• Never go underneath equipment (lowered to the ground or raised) unless it is properly blocked and secured. Never

place any part of the body underneath equipment or between moveable parts even when the engine has been turned

off. Hydraulic system leak down, hydraulic system failures, mechanical failures, or movement of control levers

can cause equipment to drop or rotate unexpectedly and cause severe injury or death. Follow Operator's Manual

instructions for working underneath and blocking requirements or have work done by a qualified dealer.

Maintenance

• Service and maintenance work not covered in OWNER SERVICE must be done by a qualified dealership. Special skills,

tools, and safety procedures may be required. Failure to follow these instructions can result in serious injury or death.
