• Evaluate the terrain to determine how to safely
perform the job. Only use accessories and
attachments approved by the manufacturer.
• Clear the area of objects such as rocks, toys,
wire or any other debris that may be thrown or
get tangled in the seeder.
• Be sure the area is clear of pets and people,
especially young children. Never assume they

Keep guards, shields and interlock safety de-
vices in place and in proper working condition.
They are for your protection.
• Keep all fasteners such as nuts, bolts, and pins
well secured.
• Check for damaged parts – Before further
use of the seeder, a guard or other part that
is damaged should be carefully checked to
determine that it will operate properly and
perform its intended function. Check for
alignment of moving parts, binding of moving
parts, breakage of parts, mounting, and any
other condition that may affect its operation.
A guard or other part that is damaged should
be properly repaired or replaced.
• Verify that machine and attachments, if any,
are in good operating condition.
• Do not engage seeder until ready to use.
• The engine housing and exhaust remain hot
for a short period after the seeder is turned
OFF. Allow the engine and exhaust to cool
completely before touching or storing near
combustible material.
OPERATING SAFELY

INTERRUPTING OPERATION
Before leaving the operator’s
position, shut off engine.
• Stop the engine, disengage the blade, set
parking brake and wait until the blade stops
rotating:
- before refueling.
- before making depth adjustment unless the
adjustment can be made from the operator’s
position.
• Stop the engine, disengage the seeder, set
parking brake, and wait until the blade stops
rotating and disconnect the spark plug wire:
- before clearing blockages or unclogging;
- before checking, cleaning or working on the
machine;
- after striking a foreign object. Inspect the
machine for damage and have repairs made
as needed before restarting;
- if the machine begins to vibrate abnormally:
shut off machine immediately. Inspect
and have repairs made as needed before
restarting;
- except for repairs or adjustments as
specically noted, such as for carburetor
adjustment, where the engine must be
running. Keep hands and feet clear of
moving parts in these circumstances.
• Allow the seeder to come to a complete stop
when stopping operation to clear blockages,
unclog, inspect the machine, do maintenance
or repair.
• Reduce the throttle setting during engine
shutdown and, if the engine is provided with a
shutoff valve, turn the fuel off at the conclusion
of operation.
MAINTENANCE SAFETY
Maintain machine according to manufacturer's
schedule and instructions for maximum safety and
best results.
• Park machine on level ground.
• Never allow untrained personnel to service
machine.
• Guards should only be removed by a qualied
technician for maintenance or service.
Replace when work is completed.
• Adjust or repair only after the engine has been
stopped and the seeder has stopped moving.
• Disconnect spark plug wire(s) before doing any
maintenance.
• Replace parts if worn, damaged or faulty.
For best results, always replace with parts
recommended by the manufacturer.
• Do not dismantle the machine without releasing
or restraining forces which may cause parts to
move suddenly.
• Provide adequate support, e.g. jack stands for
lifted machine or parts if working beneath.
• Do not put hands or feet near or under rotating
parts.
• Clean up spilled oil or fuel thoroughly.
• Replace faulty mufers.
• To reduce re hazards, keep the engine,
mufer, and fuel storage area free of grass,
leaves, debris buildup or grease.
• Never attempt to make adjustments while
the engine is running except for repairs or
adjustments as specically noted, such as
for carburetor adjustment, where the engine
must be running. Keep hands and feet clear of
moving parts in these circumstances.

STORAGE SAFETY
• Stop the engine and allow to cool before storing.
• Drain the fuel tank outdoors only.
• Store fuel in an approved container in a cool,
dry place.
• Keep the machine and fuel containers in a locked
storage place to prevent tampering and to keep
children from playing with them.
• Do not store the fuel container or equipment with
gasoline in the tank inside a building where fumes
may reach an open ame or spark.
• Appliances such as furnaces and water
heaters with a pilot light have an open ame.
• Keep gasoline storage area free of grass, leaves
and excessive grease to reduce re hazard.
• Clean debris from cutting units, drives, mufers
and engine to help prevent res.
• Clean up any spilled gasoline or oil in the
storage area.
•
• Store the seeder in a sheltered, dry, frost free,
well-ventilated place.
•
• When not in use, the seeder should be stored
indoors in a locked-up place out of the reach of
children.
FUEL SAFETY
• Gasoline is ammable; gaso-
line vapors are explosive.
Use extra care when handling.
• Store only in containers specically designed
for fuel.
• When refueling or checking fuel level:
- Stop the engine and allow to cool;
- Do not smoke;
- Refuel outdoors only;
- Use a funnel;
- Do not overll;
- If fuel is spilled, do not attempt to start the
engine until the spill is cleaned up and va-
pors have cleared.
- Replace caps on fuel containers and tanks
securely.
Sparks from static electricity can start res or
cause explosions. Flowing fuel can generate static
electricity. To prevent static electricity sparks:
• Keep containers electrically grounded. Do not
ll containers in a vehicle or on a truck or trailer
bed with a plastic liner. Fill containers on the
ground away from the vehicle.
• When practical, remove gasoline powered
equipment from the truck or trailer and refuel it
on the ground. If equipment must be refueled
on the truck or trailer, refuel from a portable
container rather than a dispenser nozzle.
• Keep the dispenser nozzle in contact with the
rim of the fuel tank or container opening until
fueling is complete. Do not use a nozzle lock-
open device.
• If fuel is spilled on clothing change it
immediately.
WARNING
BLADES
• Blades are sharp and can
cut. Use extra caution when
handling. Wear appropriate
personal protective equipment.
• Only replace blades. Never straighten or weld
them.
• Keep other persons away from blades.
