MAINTENANCE SAFETY

In general

• Read and understand the manual before maintenance on machine.

• 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 qualified technician for maintenance or service. Replace when work is complete.

• Adjust or repair only after the engine has been stopped and the tines have quit rotating.

• Replace parts if worn, damaged or faulty.
  For best results, always replace with parts recommended by the manufacturer.

• Disconnect spark plug wire(s) before making any repairs.

• 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 mufflers.

• To reduce fire hazards, keep the engine, muffler, and fuel storage area free of grass, leaves, debris buildup or grease.

Tines

• Tines are sharp and can cut. Use extra caution when handling. Wear appropriate personal protective equipment.
• Only replace tines. Never straighten or weld them.
• Keep other persons away from tines.

Fuel

• Petrol (gasoline) and diesel fuels are flammable; petrol (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 fuel containers electrically grouded.

• 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 gas 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 lockopen device.
