Whether the cooperation gap between the forks and the forks is too large, these factors will cause the electric pallet jack to make abnormal sounds when it is in use. Check the electric pallet jack for loose or worn tires, damaged bearings, etc. Whether the gear pump of the electric pallet truck is abnormal.
