1. When transporting loads: The forks should be raised high enough to clear any obstacles in the path of travel, such as uneven ground, ramps, or other objects. Typically, the forks should be raised to about 4-6 inches off the ground.
2. When stacking or loading/unloading: The forks should be raised to the appropriate height to safely and efficiently place or remove the load. This may vary depending on the height of the storage racks, truck beds, or other loading/unloading areas.
3. When traveling with an empty pallet or forks down: The forks should be lowered all the way to the ground to minimize the risk of striking objects or causing damage.
It's important to note that these are just general guidelines, and the specific requirements may vary based on the specific forklift, the load being handled, and the operating conditions. Always refer to the manufacturer's instructions and the specific safety regulations for forklift operation in your jurisdiction to ensure proper and safe operation.
