FUEL SAFETY

Gasoline is flammable; gasoline vapors are explosive. Use extra care when handling.
Store only in containers specifically 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 overfill;
- If fuel is spilled, do not attempt to start the engine until the spill is cleaned up and vapors have cleared.
- Replace caps on fuel containers and tanks securely.

Sparks from static electricity can start fires or cause explosions. Flowing fuel can generate static electricity. To prevent static electricity sparks:

Keep containers electrically grounded. Do not fill 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.

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 flame or spark.
Appliances such as furnaces and water heaters with a pilot light have an open flame.
Keep gasoline storage area free of grass, leaves and excessive grease to reduce fire hazard.
Clean debris from cutting units, drives, mufflers and engine to help prevent fires.
Clean up any spilled gasoline or oil in the storage area.

Pull right engagement arm up to move forward or push down to move in reverse.

SEEDING AND SLICING OPERATION

The seeding blades are used for cutting grooves for over-seeding and can also be used for verti cutting grasses. To set the height properly, place unit on the lawn surface and adjust the wheel height up. Adjusting the wheel height up lowers the blades. Figure 1
SEEDING: The proper height setting for over-seeding is approximately 1/4” into the ground. Adjust the wheel height up approximately one notch. If set deeper, grass seed being applied may not germi-nate.
SLICING : The proper height setting for slicing is 1/2” to 3/4” into the ground. Adjust wheel height up one or two notches.
For crawling grasses such as Zoysia, Bermuda, Ba-hia, etc. raise the wheels only one notch. Crawling grasses should not be sliced too deeply.

For single strand grasses like Bluegrass or Rye, aerate in perpendicular directions for more even slicing. For example. slice in a North-south direction on the first pass, switching to an East-West direction on the second pass.
As the seeder blades wear they may be rotated to provide a new cutting edge. The wheels may be raised to allow the blades to penetrate deeper into the ground.
