Clark GTS20, GTS25, GTS30, GTS33 D,L Forklift Operators Manual (OM-1064)

These Clark GTS20–GTS33 D,L forklifts spend their lives loading trucks, feeding production lines, and shuttling pallets around yards and warehouses. This operator’s manual is what I’d keep on hand to make sure the truck is started, driven, and shut down the way Clark intended, so we don’t cook transmissions or crack masts through bad habits. If an operator reports rough starts, warning lights, or sluggish hydraulics at the beginning of a shift, this book walks you through the correct control checks and daily inspections to trace simple issues before they turn into shop visits.

Applications & Use Cases

• Verify proper startup and shutdown so you’re not dry-starting the engine or killing it under load.
• Check daily fluid levels and leaks to protect the engine, hydraulic system, and brakes from avoidable damage.
• Confirm correct use of lift/tilt controls to avoid side-loading the mast or dropping loads hard.
• Coach new operators on safe travel, parking, and load-handling habits in tight warehouse aisles or outdoor yards.
• Diagnose basic operator complaints (slow lift, odd noises, warning indicators) before calling in a mechanic.

FAQ

Q: Can I keep this manual on a tablet or phone in the cab?

A: Yes, a digital copy works well; just make sure it’s saved offline so you can open it even without signal.

Q: Is it worth printing pages from this manual?

A: I’d print the startup checks and safety pages, laminate them, and keep them at the dispatch desk or near the charger/fuel station.

Safety Note

Always follow the manual’s startup, inspection, and shutdown steps before lifting any load.
