Forklift Maintenance Course
Master every system on a forklift — from hydraulics and electrical controls to brakes, mast assemblies, and powertrains. This course gives working technicians the hands-on knowledge to perform professional-grade maintenance, pass compliance audits, and keep equipment running safely. If you turn wrenches for a living, this is the training that moves your career forward.
What you will learn:
You will learn how to safely inspect, service, and repair all major forklift systems, including LP gas, diesel, and electric powertrains. The course covers hydraulic pump and cylinder rebuilds, electrical fault diagnosis using wiring diagrams and scan tools, and complete mast and fork overhaul procedures. You will also develop skills in preventive maintenance scheduling, fluid analysis, brake and steering service, and regulatory compliance documentation. Supplementary topics include telematics and fleet management, environmental waste handling, parts inventory control, and technical report writing. By the end, you will have the knowledge to certify equipment as fit for service and advance towards industry credentials.
