Operation; Attaching Cutter To Tractor - Oregon 480RC Original Instruction Manual

OPERATION

Operation
The intended use of this standard-duty cutter is for grass
and weed mowing applications.
The operator is responsible for the safe operation of the
cutter. The operator must be properly trained. Operator
should be familiar with the tractor, the cutter, and all safety
practices before starting operation. Read the safety rules
and safety decals on page 6 through page 11.
Recommended mowing speed for most conditions is from
2 to 5 mph.
DANGER
Full shielding must be installed when operated in
populated areas or other areas where thrown objects
could injure people or damage property.
This shielding is designed to reduce the risk of
thrown objects. The mower deck and protective
devices cannot prevent all objects from escaping
the blade enclosure in every mowing condition. It is
possible for objects to ricochet and escape, traveling
as much as 300 feet (92 m).
WARNING
• Read and understand this manual and tractor
operator's manuals before operating the unit. Know
how to stop the tractor and cutter quickly in an
emergency. Failure to do so may result in death,
serious personal injury or property damage.
• 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.
• Never allow riders on power unit or attachment.
• Do not allow bystanders within 25 feet of the area
when operating, attaching, removing, assembling,
maintaining, or servicing equipment.
• Operate tractor PTO at 540 RPM. Do not exceed.
12
• 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 or front tractor weights. Weigh
the tractor and equipment. Do not estimate.

CAUTION
• Stop power unit and equipment immediately upon
striking an obstruction. Turn off engine, set parking
brake, remove key, inspect, and repair any damage
before resuming operation.
• 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.
