OM Pimespo XG 25, XG 30, 4141, 4159, 4257 2002 Workshop Manual

I’ve seen more forklift repairs go sideways because some tech grabbed a third-party manual than I care to count. The problem? Wrong torque values, missing safety lockouts, and wiring diagrams that look like a kindergartner drew them. That’s why when I see an original OEM OM Pimespo XG 25, XG 30, 4141, 4159, 4257 2002 Workshop Manual, I know the job has a fighting chance. This is the same binder the factory sent to the dealerships. 370 pages of actual engineering intent. Not some scanned-and-OCR’d mess.

Chapter 00: The Safety Section That Keeps You Employed

Page 2 starts with how to use the manual – don’t skip it. Page 3 kicks off general safety instructions covering electrical system lockout, hydraulic pressure release, and the right way to detach and reattach parts. Section 00.3 goes into safety warnings for operating the truck: checking seat belt anchorages, what to do if the truck tips over, and how to inflate tires without blowing a bead. The manual even shows the location of warning plates (page 12) so you can confirm your truck still has the correct decals for operators. That’s the kind of detail that keeps a shop out of OSHA trouble.

Engine Manual Cross-Reference – Where to Find the Actual Torque Specs

Chapter 31 clearly states that for engine work, you need to refer to separate publications. Standard models use publication 604.24.180, heavy duty uses 604.24.152, and LPG uses 604.24.161. The gearbox has its own set: standard 604.24.178, heavy duty 604.24.175, and LPG 604.24.178. Don’t complain that this manual lacks engine torque specs – it’s designed to hand you off to the correct factory source. That’s what real OEM documentation does. For the engine itself, grab the OM Pimespo H25 Engine Repair Manual XG 25 30 when you need internal specs.

6 Systems Covered Beyond the Engine

This manual covers the whole truck frame-up. Chapter 10, 20, and 30 handle the chassis, hydraulic system, and drivetrain. Chapter 31 walks through the mast assembly – removal, installation, adjustments, and technical operating data. The introduction and checks/adjustments sections give you baseline pressures and measurements. If you’re working on an earlier Series 4016 or 4017, compare the safety structure in OM PIMESPO Shop Manual Series 4016 4017 – Section: Chapter 00 Contents – it follows the same logic. For the XE22ac/XE30ac platform, see OM Pimespo XE22ac/XE30ac Series 4024 Workshop Literature.

Don’t Skip the First Page – How to Use the Manual Properly

Page 2 shows you exactly how the manual is organized. Most techs jump straight to the part they need and miss the safety cross-references. This manual includes a contents page that lists every chapter and subchapter. Read section 00.1 first. It explains the symbols used, the torque value format, and where to find the exploded views. That five-minute read can save you a stripped bolt or a hydraulic face full of hot oil.

Why OEM Documentation Matters on a 4141 Series Forklift

Aftermarket manuals for these Italian-built OM Pimespo units are notorious for mixing up the XG 25 and XG 30 brake specs or using generic transmission diagrams. This factory manual was printed in 2002 by OM Pimespo itself. The wiring colors match, the part numbers for the safety switches are correct, and the mast shim specs come from the actual assembly line. I’ve got no patience for guesswork, and neither should you. Transmission work? The standard gearbox manual (604.24.178) covers the Manual Transmission if your unit has one. For context on broader industry standards, the Automotive Industry Overview shows how these factory procedures align with global service expectations.

Does this manual include torque specs for the mast?

No. The manual references separate engine and gearbox manuals for torque values and internal adjustments.

What safety procedures are covered?

Section 00.2 through 00.5 cover everything from electrical system lockout to hydraulic pressure release, safety belts anchorages, and what to do if the truck tips over. Page 3 lists general safety instructions, and page 7 explains the safety device that stops engine start-up if the speed lever is engaged. The manual even includes location of warning plates (page 12) so you can verify your truck still has the correct decals for operators.

If you’re working on a 4141, 4159, 4257 XG 25 or XG 30, get the Factory Manual before you touch a wrench. Access the Factory Manual from AutoRepairManuals and keep it on the bench.
