  • Page 62: Forks And Upright

    Forks and Upright Positioning the Forks for Traveling When traveling with or without a load, it is recommended to have the forks raised slightly and the upright tilted back. This helps prevent the fork tips from catching on the ground or debris while traveling.
  • Page 63 Section 5. Operating Your Lift Truck Adjusting the Forks The forks are adjustable on the carriage. When carrying a load, the forks should be spaced as far apart as possible. Position each fork an equal distance from the center of the carriage. Raise the carriage so that the forks do not contact the ground.

  • Page 64: Load Handling

    Load Handling Overview • Always handle loads that are at or below the lift truck’s rated capacity. The rated capacity can be found on the lift truck’s data plate. This rating specifies the maximum load that should be lifted. However, other factors such as using a special attachment, handling loads with a high center of gravity, or traveling over uneven surfaces may reduce the safe working load to be less than the rated capacity.
