Lull M25RH 1993 Operators Manual – What You’re Actually Getting

You own a Lull M25RH power buggy. Or you’re about to work on one. That machine moves concrete and material on rough terrain – it’s not a toy. If you’re running it without the factory Lull M25RH 1993 Operators Manual, you’re trusting memory or a photocopy that may have missed critical updates. I’ve seen too many guys skip reading the warnings, then pinch a hand in the steering linkage or misroute a cable because the aftermarket diagram was wrong. This 18-page manual, issued August 1993, is what the factory sent with the unit. It covers safe operation, assembly part numbers, and a service bulletin that fixed a control handle problem. You need the spec – not guesswork.

What’s Inside: Warnings, Assembly, and a Service Bulletin

Page 1 hits you with the warning you cannot ignore: “Read and observe all warnings on the unit before operating it. Do not operate this equipment unless all factory installed guards and shields are properly secured in place.” That’s not a suggestion – that’s liability prevention. The manual then dives into engine-pump subassembly details with part numbers like 07243007 for the hydraulic pump and 7243007 for the clutch assembly. It shows the main frame, covers and supports, and the platform. Page 4 contains a service bulletin update on the M25RH control handle and cables – part numbers for the cable (07223001), springs, clamps, and the bracket. That bulletin fixes a known issue where the cable routing could bind. If you’re chasing a sticky control, that page alone saves you hours of head-scratching.

Factory OEM vs. Aftermarket: Why It Matters Here

Aftermarket manuals for this era of Lull often reprint the illustrations without the part number revisions. I’ve seen a manual labeled “Lull M25RH” that used an incorrect pump mount bracket because they copied an earlier print. This Operators Manual is the original 1993 release – part number 7246003 printed on the cover. The exploded views show fastener callouts like bolt 11143-05 and washer 07171002. You can order parts by those numbers and know they fit. No reprints, no third-party edits. That’s the difference between a rig that runs and a rig that leaks.

Control Handle Update: The Page You’ll Reference Most

Page 4 includes a hand-drawn service bulletin sketch showing the control handle bracket and the correct cable angle (45° at the engine and pump). The update calls for new cables, two springs, and a washer with a slot cut to clear the pump mount. If your M25RH binds when you pull the steering levers, this is where the fix lives. The manual lists every part – handle grips (2-00010-02-C), clamp (15677-07), even the hair pins. You don’t need to hunt for superseded numbers; they’re right there.

Who Should Buy This 18-Page Manual?

Anyone who operates, maintains, or repairs a Lull M25RH. It’s thin – only 18 pages – but that’s because it’s focused on what the operator and mechanic need daily: starting procedure, safety rules, cable routing, and component breakdowns. If you’re a shop that rents these buggies out, you need a copy in the glovebox so the rental guy can’t say he wasn’t warned. If you’re a home owner who bought a used M25RH at auction, this manual tells you if all the guards are present and how to adjust the steering. It’s not a service manual – it won’t tell you how to rebuild the hydrostatic pump – but it gives you the foundation to operate safely and order the right parts.

Where’s the Torque Data?

This Operators Manual does not list torque specifications for fasteners. It shows bolt sizes and part numbers, but you’ll need the factory service manual for torque values on engine mounts, wheel nuts, or pump bolts. However, it does identify every fastener by part number – that lets you cross-reference to Lull’s torque chart. If you’re looking for fluid capacities, those aren’t in this 18-page version either. For that, grab the Lull L-812 1983 Parts Catalog – OEM Factory Parts Breakdown or the Lull LD50, LL40 1985 Parts Catalog – OEM Factory Specs – those include capacities and part callouts for related models.

Does this manual include torque specifications for engine mounting bolts?

No. This is an operators manual; it shows part numbers but not torque values. You need the factory service manual for that.

How do I get the complete factory service manual for the Lull M25RH?

We carry the full library of Lull documentation. The repair and service manual for the M25RH covers disassembly, rebuilding, torque specs, and troubleshooting. It’s a separate document from this operators manual. Check our catalog for the specific service manual – it will have the hydrostatic pump overhaul steps and wheel hub bearing preload values. This operators manual is your safety and operation document; the service manual is your deep-dive repair guide. Both are OEM, not aftermarket. If you’re unsure which you need, call or message us – we’ll steer you straight.

This manual is the starting point. You need it on the shelf if you care about safe operation and correct parts. Don’t run that buggy blind.
