the lift truck is level. Do not turn on or drive across
an incline.

crossing, cross the railroad diagonally so one wheel
crosses at a time.
Avoid running over loose objects.

persons or obstructions in your path of travel.

from the edge of docks, ramps and platforms.
Always watch tail swing.
The truck can fall over the edge and cause injury or
death.

support the weight of the truck and load.
Make sure that they are correctly positioned.
