SAFETY

To prevent accidents, read through the following items before starting work, and always regard safety when working. It is your responsibility to ensure your safety on the job.

PREPARATIONS

1. Select a work site which is level, sufficiently spacious and not in the vicinity of dangerous objects.
2. Avoid poorly ventilated rooms. Asphyxiation from exhaust fumes is always a possibility that accompanies a running engine.
   
3. Working clothes which may be pinched or caught in the equipment must not be worn. Loose clothing can cause serious injury or death.
   
4. Always wear a mask and protective goggles during work when dust or flying debris is thrown about.
   

ASSEMBLY AND ADJUSTMENTS

1. Before assembling equipment, read the assembly instructions for the product to become familiar with the equipment and procedures.
   
2. Use only adequate and required equipment, tools and instruments (torque wrench or battery hydrometer).
3. Set the parking brake and place blocks in front of wheels to prevent machine movement.
4. Lower the attachment or implement to the ground before assembling or adjusting equipment.
5. Before working under suspended or raised equipment, support the equipment or attachment with stands or suitable blocking beforehand to prevent the machine from falling or moving out of place.
   
6. Keep fire from cigarettes, matches or other ignition sources away from fuel, oil, antifreeze and other flammable materials.

AFTER ASSEMBLY CHECK

1. Once the equipment is fully assembled, select a safe place for a test run. Prevent onlookers from approaching the equipment.
   

To avoid serious injury or death:

• Do not start engine or operate levers from anywhere other than the seat.
  

To avoid serious injury or death:

• Do not bypass-start the equipment. Short circuiting the starter terminal runs the risk that the equipment will start operating or moving unexpectedly.
