Expert Tip: When your forklift won't travel or lift, always check the seat switch first. Before replacing the switch, verify that the seat cushion is properly seated and applying enough pressure to the switch plunger. Sometimes a worn-out seat cushion is the real culprit, preventing even a brand-new switch from engaging!
