I have a 6 month old forlift that gets used roughly 10 hours per week. I have been having an issue with it jerking forward when the forks are roughly 12-15 feet in the air. As I boom the carrage out the forklift all off a sudden jerks forward causing me to pull the joystick backward to counter the movement. This action does not happen everytime but it has hapened probably a dozen times since we got it. I have come close to losing a couple of loads and taking out racking because of this issue. It is a huge safety concern as the forklift is jolting forward on its own!

Has anyone experienced this before or know why it might be happening?
