PAT America DS 350, 1334 2001 Operators Manual

If you are running a lattice boom crane without the factory Load Moment Indicator (LMI) calibration data, you are gambling with overload conditions. I have seen too many field techs trust a generic third-party diagram and end up with a boom angle that is 3 degrees off—that is a bent boom or a dropped load waiting to happen. This PAT America DS 350, 1334 2001 Operators Manual is the original OEM document from PAT America, Inc., released in October 2001 (Revision E, P/N L-B J5L0031 / PAT 031-300-190-089). It covers both the DS 350 and 1334 Graphic systems for lattice boom cranes. You get 50 pages of setup procedures, limit-setting instructions, and calibration steps that PAT America wrote for their own hardware. If you need to configure pile driving applications or zero the force and angle sensors, this is the only document you should trust on the workbench.

Warnings: Read These Before You Power On

Page 2 of the manual lists warnings that PAT America considers mandatory. The manual states that the LMI must not be used if any visible damage exists, and that the system must be calibrated after any boom or jib change. I have seen guys skip this step because they were in a hurry and later had the LMI alarm at the wrong radius. The warnings section is only one page, but it references legal liability—PAT America makes it clear that ignoring these warnings voids any warranty and shifts responsibility to the operator. That is not bluffing; that is a direct quote from page 1 of the notice.

System Description and Control Identification

Chapter 3 describes the system function and operating console. You get a full breakdown of the DS 350 display, including what each symbol means. Section 3.3 covers control identification—exactly which button does what for radius limit, boom angle, and tip height. The manual expects you to know that pressing the INFO key brings up crane configuration. If you have ever tried to change a limit setting on a PAT system without the factory maps, you know how frustrating it is to guess which menu level you are in. This chapter kills that guesswork.

Configure the LMI Setup Correctly

Chapter 4 is where the manual earns its keep for anyone running a pile driver attachment. Section 4.1 covers pile driving application setup, which is not in most aftermarket cheat sheets. Section 4.2 walks through the LMI setup procedure step by step, including the hoist-in-use quick selection (section 4.3) and crawler position quick selection (section 4.4). I have watched techs try to force a generic LMI configuration into a PAT system—it never ends well. This manual gives you the exact sequence of key presses and the expected display readouts. You can reference page 10 for the pile driving section, but the whole chapter runs from page 10 to page 17, so take the time to read it.

Operation: Limit Setting and Info Crane Configuration

Chapter 5 covers limit setting for radius, tip height, and boom angle. Sections 5.1.1 through 5.1.3 each have their own sub‑procedures with the factory tolerance ranges. Section 5.2 explains the INFO CRANE CONFIGURATION menu—this is where you verify that the crane configuration matches the actual rigging before you start lifting. The manual also has a display contrast control (section 5.3) that is easy to overlook if you are troubleshooting a dim screen.

3 Key Calibration Procedures

Calibration is covered in Chapter 9, which takes up 14 pages. Section 9.2 covers calibration configuration setup, section 9.3 goes into zero settings with force sensor adjustment (9.3.1) and angle sensor adjustment (9.3.2). Section 9.4 details main boom calibration (9.4.1) and jib calibration (9.4.2). If you are swapping out a jib, you need to run the calibration procedure documented on pages 41-43. The manual also lists the material required for calibration on page 36—it includes a known weight, a tape measure, and a spirit level. No shortcuts. The calibration memory is non‑volatile, but you need to know that zeroing the force transducer requires a specific keystroke sequence. That is all here, written by PAT America engineers, not by a technical writer guessing from a phone photo.

Who This Manual Is For and Why It Matters

If you are a operator, a crane rental yard manager, or a field service technician who touches Lattice Boom cranes with PAT America DS 350 or 1334 systems, this manual belongs in your truck. It is not for a guy changing oil on a half‑ton pickup. It is for anyone who needs to set up a crane configuration, verify limit settings after a boom change, or troubleshoot a system that is showing a calibration error code. I have used the troubleshooting section (Chapter 8) to locate a bad angle sensor wire in twenty minutes, where a shop without the manual spent three hours chasing a ghost. That is real time saved on the job.

Source Validity: OEM Documentation vs. Aftermarket Reprints

I have seen reprints that are photocopies of photocopies—the wiring labels blur out, the torque values get lost in the noise. This manual is a genuine digital copy of the PAT America original, Revision E, dated October 19, 2001. The manual explicitly states that it contains proprietary information and is protected by copyright. PAT America reserves rights to all drawings and data. That means every schematic, every calibration step, every warning notice is as close to the factory source as you can get without buying a brand‑new LMI system. If you cross‑reference the page numbers with the original binder, they match. You are not guessing.

Frequently Asked Questions

Does this manual cover calibration for the DS 350 and 1334?

Yes, chapter 9 covers calibration completely, including zero settings, force and angle sensor adjustments, and main boom/jib calibration.

What machine models are included?

PAT America DS 350 and 1334 Graphic systems for lattice boom cranes.

How many pages and what year was it published?

50 pages, published in 2001 (Revision E, dated October 19, 2001).

Is this the original OEM manual or a reprint?

This is a digital copy of the original PAT America operators and calibration manual, part number L-B J5L0031 / PAT 031-300-190-089. The manual includes manufacturer copyright, proprietary notices, and revision history. It is not a third‑party rewrite or a scanned paperback with missing pages. Every section from general information (page 1) through calibration (pages 36-43) is intact. If you need the official PAT America procedure for setting radius limits or calibrating the jib angle sensor, this is it. Aftermarket manuals often skip the pile driving application instructions (section 4.1) and the hoist‑in‑use quick selection sequence—this manual includes them.

You can also pair this operators manual with the PAT DS 350 Rated Capacity Limiter Service Manual for deeper service-level procedures, or the PAT DS 350 Load Moment Indicator Service Manual for electrical troubleshooting. If you need the rated capacity limiter operator guidance for both models, check out the PAT Rated Capacity Limiter DS 350 / 1334 Operator Manual.
