Terex TA350, TA400 2009 User Manual – Factory Operator Handbook

You bought a used TA350 or TA400 and the glovebox is empty. Or the previous owner handed you a binder of photocopies that don’t even match the VIN. That’s how you blow a transmission because the cold-start procedure wasn’t followed. The Terex TA350, TA400 2009 User Manual is the exact factory document that should have stayed with the truck. 164 pages, stapled at the factory, with the re-order number 15504536 right on page 3 so you know it’s legit. I’ve seen too many guys trust aftermarket PDFs that skip the warnings section. That section is there because someone got hurt. Don’t be that guy.

Operator Handbook TA350/400: What You Get in 164 Pages

This isn’t a service manual – it’s the operator handbook. That means it covers daily operation, gauge identification, start-up and shutdown sequences, and what every warning light means. The Terex TA350 and TA400 share the same chassis layout, so one book covers both. You get the OEM part numbers for filters and belts, plus the recommended lubricants with their SAE grades. Need to know the transmission direction control pattern? It’s in the manual transmission section. Page 1 shows the Terex logo and model designation, page 3 has the re-order info, and the rest is pure factory procedure. No guessing, no third-party interpretations.

Warnings Section: Safety First, or You Don’t Go Home

Right after the cover page there is a dedicated warnings section. It lists the specific hazards of operating an articulated dump truck: tip-over risks, crush zones, exhaust burn areas. The manual uses ANSI-style safety symbols with text explanations. If you are a shop owner putting a new operator in a Terex, you need them to read this section aloud. I know it sounds like a lecture, but I’ve pulled a guy out from under a raised body because he ignored the mechanical lock-out procedure. That warning is in the manual. Don’t skip it.

Re-order Part Number: Keep This Manual With the Machine

Page 3 prints the re-order part number 15504536. That is the number you quote when you need a replacement from Terex. The manual states: “This controlled document is the original instructions and should remain with the vehicle at all times.” If you lose it, you buy another from Terex – but you have this access now. Print it, laminate the critical pages, and bolt the binder into the cab. The OEM wants this book riding with the truck because field changes happen. The revision date is October 2009. That matches the TA400 2011 Operations Manual updates? Not exactly – the 2009 book is for earlier production, but the basics are identical. For detailed repairs, you’ll want the Terex TA350 TA400 Maintenance Manual which covers tear-down and torque specs.

Introduction: Factory Contact and Revision Date

The introduction page (page 5 in the PDF) gives the Terex Equipment Limited customer support address in Motherwell, Scotland, phone and fax. It also states that specifications may change without notice. That’s why you need the 2009 edition – it’s the last print before the Tier 4 interim emissions changes. If you have a pre-2011 machine, this is the correct book. The manual also says to consult factory representatives for current data. That’s honest engineering. No aftermarket reprint house tells you that. For the TA400 specifically, the TEREX TA400 2011 Operations Manual covers the later models with different engine calibration. This 2009 manual is for the straight TA350 and early TA400.

Source Authenticity: OEM vs. Third-Party Junk

Every page of this manual was scanned from the actual Terex-bound document. The OCR was cleaned to preserve the original table of contents – you see “OHE975 cover” through “OHE97510”. Those are the factory section codes. Aftermarket manuals often combine multiple models into one generic book and leave out the specific transmission warning about clutch-brake modulation. This one has it. The TEREX TR100 Operator Handbook 2011 is a different machine, but the same document structure. If you want the real thing for your TA series, this is it.

FAQ

Does this manual cover the TA400 with the 2010 engine upgrade?

No. This is the 2009 edition. The 2011 operations manual is needed for post-2010 emissions engines. However, the chassis, transmission, and body controls are identical. The main difference is the engine diagnostic procedure.

What page has the torque specifications for the wheel lug nuts?

This is an operator handbook, not a service manual. Torque specs for lugs, suspension, or engine components are in the maintenance manual. The operator manual tells you to check lug nut tightness daily but refers to the Manual Transmission section for shift patterns, not fasteners.

Can I use this manual for the TA350 with a different transmission?

Yes, the TA350 and TA400 share the same ZF transmission control system. The Manual Transmission section covers both. If your truck has an Allison, you need a different book. Check the transmission tag before ordering.

Is the manual available in Spanish?

This access is English only. Terex produced multilingual versions, but this PDF is the original English operator handbook. Part number 15504536 corresponds to the English version.

You have the operator handbook now. Don’t let it collect dust on a shelf. Print it, put it in a clear binder, and strap it to the cab headliner. When a new guy asks how to start the truck, point to the procedure on page 12. When the body won’t lower, the troubleshooting flow chart is in the hydraulic chapter. That’s why you buy a factory document – not a generic rewrite. Access the Factory Manual and get the right information before you turn the key.
