Manitou Mlt940-120 LSU Series 3-E3 Operators Manual

You’ve got a Manitou MLT940-120 LSU Series 3-E3 rough terrain forklift on your property. Maybe it’s moving pallets on a farm or loading trucks on a construction site. You need the instructions that came from the factory – not some third-party rewrite with missing torque specs and fuzzy diagrams. This is the actual Manitou Mlt940-120 LSU Series 3-E3 Operators Manual, 120 pages of what you need to operate this machine without wrecking something. I’ve been turning wrenches since before some of you were born, and I can tell you: the OEM booklet is the only thing I trust for safety procedures and basic maintenance.

Manitou MLT940-120 LSU Series 3-E3 Operators Manual – What This Manual Covers

Page 3 lists the table of contents: Introduction to Safety, General Safety Standards, Safety Messages, Safety Decals, Operating and Safety Instructions, Description, Maintenance, and Engaging the Attachments. Each section is written for the operator – not a service tech. If you’re the guy who climbs in and starts pushing buttons without reading, this manual will save you from flipping the machine over or blowing a hydraulic line. Thirty years in the shop, and I’ve seen what happens when people skip the intro.

Introduction to Safety – Why You Read This First

Manitou starts every manual with safety because they know the stakes. The Introduction to Safety section (pages 2–5) covers the general safety standards for rough terrain forklifts. It tells you what those warning decals mean, how to interpret signal words like DANGER and CAUTION, and where to find the serial plate. This is not fluff. If you’ve ever had a load shift because you ignored the load chart, you’ll appreciate why this section exists.

General Safety Standards – Not Optional

The General Safety Standards section spells out OSHA-style requirements: seat belt use, no riders, stability rules, and daily pre-op checks. It also lists required personal protective equipment. I’ve seen too many guys run a forklift in sandals – this manual tells you why that’s stupid. The safety decal diagrams are reproduced clearly so you can check your own machine.

Operating and Safety Instructions – Step-by-Step Procedures

Operating and Safety Instructions starts with starting the engine, moving the lift, and using the controls. It includes the correct procedure for engaging the attachments – something that gets messed up all the time. Page 4-3 specifically covers the attachment coupling sequence. If you switch buckets or forks, follow it exactly. The manual also references a Manual Transmission but this is for the torque converter lock-up, not a full rebuild. For detailed transmission work, you’d need the service manual.

Maintenance Section – When to Grease, When to Torque

Maintenance runs about ten pages in this 120-page book. It covers fluid checks, filter intervals, tire pressure, and lubrication points. Wheel lug torque values are listed – you won’t find that in a YouTube comment. The manual says to check them weekly and retorque after first ten hours on a new machine. If you’re also working on other engines, check out the K-D Manitou D 2876 LE 401-405 Operators Manual – OEM Marine Diesel or the K-D Manitou D 2866 TUE Operators Manual – Factory Specs & Procedures. For general engine operation, see Operating Instructions MAN Industrial Diesel Engines D 2876.

Don’t confuse this manual with a service manual – it’s for operators. But it tells you what to check and when. The Manual Transmission section in other manuals might cover clutch adjustment; here you get the basic shift procedure and fluid type.

Engaging the Attachments – Proper Coupling Procedure

This section (page 4-3) describes how to connect and disconnect attachments safely. It includes hydraulic lock-out steps and inspection points. I’ve had guys tell me they “just” hooked it up without cycling the pressure release – that’s how you blow a seal. This manual gives you the exact sequence.

If you’re a DIY farm owner or a beginner running a small fleet, this Operators Manual is your starting point. You keep it in the cab, read it before you start, and follow the safety decals. Aftermarket versions? They leave out torque values and safety warnings. Page 1 has the Manitou North America contact info – that tells you this is the real deal.

Who Needs This Manual and Why It’s Worth Your Time

Home garage enthusiasts and equipment owners who want to run their forklift without calling a dealer for every little thing. You don’t need to be a certified mechanic to follow these instructions. But you do need to respect the torque values and safety procedures. This manual is specific to the Mlt940-120 LSU Series 3-E3 – not generic. If you’ve got a different series, get the right manual. Using the wrong one is like using a crescent wrench on a Torx bolt – you’ll strip something.

Transfer the manual to a tablet or print it out. Either way, it must stay with the machine per the manufacturer’s requirement. That’s why Manitou prints “THIS OPERATOR’S MANUAL MUST BE KEPT IN THE LIFT TRUCK” on the cover page.

Does this manual include wiring diagrams?

No. This is an operators manual, not a service manual. It covers operation, safety, and basic maintenance, not electrical troubleshooting. You’ll need the service manual for that.

Is this the same manual that came with the forklift?

Yes. This is the factory OEM Operators Manual, part number 547980AS, published by Manitou. It must be kept in the lift truck.

Can I use this for a different model?

This is specific to the MLT940-120 LSU Series 3-E3. Different series have different specs. Cross-referencing may lead to errors.

What maintenance intervals are listed?

The maintenance section covers daily, weekly, and monthly checks. Daily includes fluid levels, tire pressure, and visual inspection. Weekly includes greasing all pivot points and checking hydraulic lines for leaks. Monthly includes torque checks on wheel lugs and attachment bolts. The manual specifies correct torque values – you must use a torque wrench, not an impact. It also includes battery maintenance and engine oil change intervals. Do not guess – use the numbers in the book.
