PAT DS 350, DS 1334 2000 Operators Manual – Factory Specs for Load Moment Indicators

Overload warnings don’t give second chances. If you’re running a lattice boom truck crane with a PAT DS 350 or DS 1334 load moment indicator and you haven’t read the factory operators manual, you’re trusting guesswork with a machine that can kill. I’ve seen too many field techs skip the step-by-step setup procedure and end up with a tipped crane or a wrecked boom. This 52-page OEM manual from 2000 gives you the exact parameters for the RCL system—not some aftermarket reprint that’s missing half the warnings.

What the PAT DS 350 and DS 1334 Operators Manual Covers

The manual starts with general information and warnings (page 1), then moves straight into system description. You get the full breakdown of the operating console, LC display, and control identification. The RCL setup procedure starts on page 10, covering hoist-in-use quick selection and outrigger position quick selection. These are the steps you need to configure the system before the crane ever lifts a load. Skip them and the load moment indicator won’t know which configuration your crane is in—that’s how you get false capacity readings.

System Description: Console, LC Display, and Control ID

Section 3 goes through the system function in detail. The operating console houses the LC display and all the control switches. The manual labels every button and LED on page 5 so you know exactly what you’re pressing. If you’ve ever stared at a PAT console with no reference, you know the frustration. This manual ends that. It also explains the display contrast control (page 38) so you can read the screen in direct sunlight or low light. No guessing.

Limit Setting Procedures: Radius, Tip Height, Boom Angle, and Virtual Wall

Page 20 starts the limit setting section. Here’s where the manual earns its keep. You get radius limitation (5.1.1), tip height limitation (5.1.2), boom angle limitation (5.1.3), and slewing angle limitation with virtual wall definition (5.1.4). Each procedure tells you exactly what values to enter and how to confirm them. If you need to set a radius limit to keep the load away from a power line, the steps are right there. The manual doesn’t assume you know the machine’s geometry—it walks you through the inputs. Use the load moment indicator theory as background, but rely on this manual for the actual keystrokes.

Pre-Operation Inspection and Calibration Verification

Section 6, starting on page 39, covers the pre-operation inspection and calibration verification. This is the part most operators rush through. The manual lists what to check on the crane configuration before trusting the RCL readout. It tells you how to verify the calibration without specialized test equipment. If the calibration is off, the troubleshooting section (page 44) helps you isolate the problem. I’ve had to talk guys through this over the phone; having the manual on the workbench saves hours of that nonsense.

Why OEM Beats Aftermarket for This Manual

Aftermarket copies of the PAT DS 350 manual often skip the notice on page 3 that says the information is subject to change without notice—and they’ll reprint old revision data. This is the original 2000 printing from PAT America, PN L-B H9L0021 / PAT 031-300-190-088. The torque specs for sensor mounts and the calibration sequences come straight from the factory. I don’t trust anything that’s been scanned, OCR’d, and reprinted on a home copier. This is the real document.

Who Needs This Operators Manual?

If you own a lattice boom truck crane equipped with a PAT DS 350 or DS 1334 RCL system, you need this manual. If your shop maintains a fleet of these cranes, every technician should have a copy. Home-garage enthusiasts who work on heavy equipment? Same thing. The manual assumes you already know how to operate the crane safely but need the specific PAT system procedures. It’s not a replacement for operator training; it’s the reference for the load moment indicator. Beginners should pair it with a crane operation guide for context.

Frequently Asked Questions

Does this manual cover the PAT iFLEX5 DS 350 systems?

No. This is for the standard DS 350 and DS 1334 from 2000. You need the PAT iFLEX5 DS 350 2003 Operators Manual for iFLEX5 variants.

What’s the difference between an operators manual and a service manual?

This manual covers operation, setup, and calibration verification. It has a troubleshooting chapter but no detailed repair or parts diagrams. For internal repairs, get the PAT DS 350 IFLEX5 2003 Service Manual.

Can I use this manual for a DS 1307?

The DS 1334 and DS 1307 are different models. The DS 350/1334 manual has specific configuration steps that may not apply. Find the PAT DS 350 1307 Operators Manual instead.

How many pages and what year is it?

52 pages, published in 2000. The PDF is searchable and printable.
