PAT DS 350 2001 Operators Manual
If you’re running a crane with a PAT DS 350 LMI system and you don’t have this 2001 Operators Manual on the seat next to you, you’re flying blind. I’ve seen too many riggers think they can skip the setup procedure and guess the reeving. That’s how you overload a boom or set the wrong work area limits. This is the OEM manual from PAT America, 61 pages of factory procedure – not a third-party summary, not a photocopy of a faded print. It’s the same document the manufacturer put in the cab in 2001.
PAT DS 350 2001 Operators Manual: Setup and Configuration
Chapter 4 – Configuration Setup – is where most guys screw up. Page 13 walks you through the LMI Setup Procedure step by step. You enter the reeving configuration, select the hoist line, and tell the system what boom extensions you’re running. Miss one digit and the load chart is garbage. The manual gives you the exact key presses and display responses. No guessing.
Understand the System Function and Operating Console
Before you touch a button, you need to understand what the DS 350 display is telling you. Section 3 – System Description – breaks down the System Function (page 5), the Operating Console (page 6), and every button on the Control Identification (page 7). The manual labels each function: what the arrow keys do, how to enter the setup mode, how to scroll through the crane configuration info. If you’ve ever stared at a cryptic LCD and wondered what “ESX” means, this section is your decoder.
Operation: LIMIT Settings and Work Area Definition
The operation chapter starts on page 21, and the meat of it is the Limit Setting section starting page 24. You get four separate procedures: Slewing Angle Limitation / Work Area Definition (page 25), Tip Height Limitation (page 32), Boom Angle Limitation (page 33), and Radius Limitation (page 36). Each one tells you exactly how to set the limits using the console. For example, the Slewing Angle function lets you define a restricted work zone – critical when you’re swinging a load near power lines or a building. The manual doesn’t just say “set the angle”; it gives you the “Call function” sequence, what the display shows, and how to confirm the setting. That level of detail is why factory manuals beat aftermarket copies every time.
Pre-Operation Inspection and Calibration Verification
Page 41? [DATA NEEDED] – The Pre-Operation Inspection section is a checklist of what to verify before you pick up a single pound. The manual tells you how to run the calibration verification routine on the DS 350. It’s not a suggestion; it’s a requirement if you want your LMI to be accurate. I’ve had guys tell me they “calibrated it once a year” – that’s not how this works. The manual spells out the procedure, including what readings are acceptable and what to do if they’re off. Ignore this and you’re trusting a box that might be lying to you.
Service, Maintenance, and Troubleshooting
When the LMI starts acting up – erratic readings, blank display, wrong boom angle – you don’t have time to call a tech support hotline. The Troubleshooting section (page number varies by revision) lists common faults, symptoms, and corrective actions. It’s not a repair manual for the internal electronics; it’s an operator-level guide to things you can check before sending the unit back to PAT. Couple that with the Appendix sections (A: detailed symbol explanation of boom extensions, B: counterweight options) and you have a complete reference for understanding what the DS 350 is telling you.
Understanding your crane’s LMI is as critical as understanding how a Manual Transmission works in a truck. You wouldn’t drive without knowing the clutch and gear pattern. Same principle applies to this indicator – you need to know how to interpret the display, how to set the limits, and when to trust the numbers. The Manual Transmission analogy holds: skip the fundamentals and you’re going to grind gears – or in this case, drop a load.
- Is this manual the same as the one that came with the crane?
- Yes, it’s a direct factory reprint of the PAT DS 350 operator’s manual from 2001, including all original warnings and diagrams.
- Does this manual cover all DS 350 variants?
- This specific 2001 revision (Rev 7, P/N 050-350-191-318) covers the DS 350/1318 Graphic display. Later models like the iFLEX5 or DS 350 with different part numbers will have different procedures. Check your unit’s serial number and compare with the manual’s part number. For later variants, see the related PAT iFLEX5 DS 350 2003 Operators Manual.
You need this on the job site. Get the factory procedures, not a third-party summary. Download the Factory Manual and keep it with the crane. Your crew’s safety depends on knowing exactly what this system is telling you – and only the OEM source gives you that certainty.
