PAT America DS 350, 1334 2002 Operators Manual

If you are running a lattice boom crane with a PAT America DS 350 or 1334 graphic rated capacity limiter, you already know the pain of aftermarket documentation. The drawings are wrong. The torque specs are missing. The wiring pinouts belong to a different revision. This Operators Manual from 2002 is the real deal – 53 pages of factory procedure that PAT America stamped and sealed. I have seen too many riggers skip the setup procedure and blame the machine when the crane tips. Don’t be that guy.

Configuration Setup: Not Optional

Section 4 in this manual covers the RCL setup procedure, and it is where most failures start. You need to enter the hoist-in-use selection (page 15) and crawler position (page 16) before the limiter knows what it is limiting. The OEM flowcharts save you from guessing which parameter locks out the boom. Without this manual, you are flying blind on configuration values that PAT America hard-coded into the DS 350 console.

Limit Settings: Radius, Tip Height, Boom Angle

Section 5.1 breaks down three critical limits – radius limitation (5.1.1), tip height limitation (5.1.2), and boom angle limitation (5.1.3). Each one has its own set of allowable values and override conditions. The factory manual tells you the exact sequence to set a slewing angle limit or define a virtual wall (5.1.4). Aftermarket copies skip these details because they reprint from photocopies of photocopies. You want the original.

Need the charge pressure? Page 73 – oh wait, this manual only has 53 pages. The point is, every spec is where it should be, not scattered across a third-party rewrite.

Why Factory OEM Documentation Beats Aftermarket

I bought a reprint manual once for a load moment indicator. The torque table was for a different model year. The wiring diagram showed a connector that did not exist on my unit. That cost me three billable hours and a blown fuse. This PAT America manual has OEM part numbers, revision history (Rev D, 04/12/02), and the copyright page proves it came from the manufacturer. The PAT DS 350 Rated Capacity Limiter Service Manual and PAT DS 350 Load Moment Indicator Service Manual go deeper into service, but for daily operation, this operators manual is where you start.

Pre-Operation Inspection and Calibration Verification

Section 6 (page 39) walks you through the pre-op inspection and calibration verification. PAT America lists the exact display contrast control procedure (section 5.3) so you can read the screen in direct Texas sun. They even include the crawl position quick selection (4.3) – a detail aftermarket manuals treat as optional. It is not optional. If your crane has a crawler, set it right or the limiter will cut your lift prematurely. This manual tells you how.

Troubleshooting Without Guessing

Section 8 covers troubleshooting. It lists error states and what to check before you pull the console. The appendixes give detailed symbol explanations for boom extensions (Appendix A) and counterweight options (Appendix B). When the display shows a symbol you have never seen, that appendix saves your day. Pair this with the PAT DS 350 / 1334 Graphic Operators Manual (yes, same manual – linking to related category) and you have the full picture. For background on how lattice boom cranes handle load limiting, see this Manual Transmission article – not the same subject, but good context on torque transfer. Another Manual Transmission resource exists, but stick with this manual for the actual procedure.

Who Needs This Manual?

Crane operators, maintenance techs, and shop owners who sign off on lift plans. If you have a DS 350 or 1334 on a lattice boom, this manual belongs in the cab or on the toolbox. It covers 53 pages of system description, configuration, limit setting, and service intervals. The audience is anyone who touches that console. Beginners? Read the warnings section (page 1) twice before you touch the setup menu.

Does this manual cover the DS 350 and 1334 graphic units?

Yes. Both models are covered, with specific configuration steps for each.

What if I need service information like sensor calibration or board replacement?

This operators manual covers daily operation, limit setting, and basic troubleshooting. For in-depth service – calibration of load cells, replacement of the console board, or wiring harness repair – you want the service manual. Look for the PAT America DS 350 Service Manual, which includes torque specs for mounting brackets and electrical test points. That manual has 200+ pages of detailed repair info. The operators manual is for the guy running the crane, not the guy pulling the console apart.

Access the factory manual now and keep your lift parameters where they belong – in OEM spec, not in a guess. Your crane’s rated capacity limiter will thank you, and so will your insurance adjuster.
