1. Regular maintenance Only qualified and trained personnel should perform maintenance work on this vehicle. Before maintenance, remove the cargo from the fork and lower the fork to the lowest position. If you need to lift the vehicle, use the specified lashing or jacking equipment. Before operation, place safety devices (such as designated jacks, wedges or wood blocks) under the vehicle to prevent accidental drop, movement or sliding.
