Manitou MLT735 120 LSU 2011 Operators Manual

I’ve torqued more head bolts than most people have had hot meals, and I know this: the difference between an operator who reads the manual and one who doesn’t is the difference between a machine that lasts 10,000 hours and one that gets scrapped. That’s why the Manitou MLT735 120 LSU 2011 Operators Manual belongs in the cab of every MLT735 on your site. 178 pages of factory-sourced data, not aftermarket guesswork.

Because this manual is the one Manitou shipped with the machine. It covers everything from rough terrain safety standards to hydraulic schematics. Page 3 lays out the table of contents: safety, operation, description, maintenance, attachment engagement, and electrical/hydraulic schematics. That’s the order you should follow if you want to keep both your equipment and your crew intact.

Rough Terrain Safety Standards

Before you touch a lever, you need to understand the ground rules. This section (page 3 of the manual) covers operator selection, site conditions, lift truck stability, and the specific instructions that the company manager and operator must follow. I’ve seen too many rollovers happen because someone skipped this part. Don’t be that guy.

Operating the MLT735 120 LSU Safely

Unladen and laden operating instructions are broken out separately. You get general operating rules, handling a load, platform operation, and even radio-control usage if your machine is equipped. This isn’t a generic “drive carefully” lecture – it’s the specific sequence for this transmission and hydraulic system. The dimensions and load chart section gives you exact capacities for the MLT 735 -120 LSU Series 6-E3 and the Powershift variant.

7 Maintenance Intervals Defined

Daily or every 10 hours, 50 hours, 250, 500, 1000, 2000 hours – each service has its own checklist. The manual identifies exactly which filters, belts, and lubricants to use for each interval. It also includes a start-up checklist and a list of Manitou original spare parts and equipment. If you’re tempted to use a generic oil filter, think again. The spec sheet lists filter cartridges and belts for multiple MLT models, so you can’t mix up part numbers.

Lubricant and Fuel Levels: What the Manual Specifies

Hydraulic oil, engine oil, transmission fluid, coolant – the manual gives the OEM fill levels and grades. There’s a dedicated section on hydraulic maintenance that includes bleeding procedures and pressure checks. I’ve seen machines eat pumps because someone used the wrong viscosity. Verify against the data in this book before you pour anything in.

Hydraulic and Electrical Schematics: Why You Need Them

The last section of the manual includes the electrical schematic and hydraulic schematic for the MLT735 120 LSU. If you’re troubleshooting a no-start or a boom that drifts, these diagrams are worth their weight in gold. They’re original factory prints, not redrawn by some aftermarket outfit. Pair them with the Manual Transmission fundamentals if you need a refresher on transmission layout.

Does This Manual Cover Attachment Engagement?

Yes. Section 4 covers picking up attachments, technical specifications of each attachment, and the required shields. If you swap buckets, forks, or work platforms, this tells you how to engage and secure them properly. Overlooking this step is how attachments drop – and drop they will.

If you’re also maintaining the diesel engine or other Manitou equipment, these related manuals fill the gaps: K-D Manitou D 2876 LE 401-405 Operators Manual – OEM Marine Diesel, K-D Manitou D 2866 TUE Operators Manual – Factory Specs & Procedures, and Operating Instructions MAN Industrial Diesel Engines D 2876. They share the same factory rigor.

One more thing – this is the 2011 initial release, catalog number 51900002. There is no later update for this exact machine. If someone tries to sell you a “universal” manual, walk away. Only the OEM document has the correct load charts and safety standards for your S6-E3 series.

For a deeper dive into drivetrain theory, the Manual Transmission article on Wikipedia is a decent overview, but it’s no substitute for the factory procedures in this manual. You need both the why and the how.

What is included in the safety standards section?

Rough terrain forklift general safety standards for operator and site.

Does this manual cover load charts for all MLT735 configurations?

Yes, the manual includes load charts for three variants: MLT 735 Turbo LSU Series 6-E3, MLT 735 -120 LSU Series 6-E3, and MLT 735 -120 LSU POWERSHIFT Series 6-E3. Each chart shows rated capacities at various boom angles and heights. You must reference the correct chart for your specific machine to avoid overloading. The dimensions and load chart section also gives overall vehicle dimensions for clearance planning. Without this data, you are operating blind.

How many pages is the manual?

178 pages.

Is the 2011 manual specific to the MLT735 120 LSU?

Yes, it is the OEM Operator Manual for the 2011 model year S6-E3 series. The catalog number is 51900002, initial release 04-2011. It applies to the MLT735 120 LSU with standard and Powershift transmissions.

If you need to keep your MLT735 120 LSU running safely and efficiently, get the factory data. Don’t rely on memory or online forums. Access the Factory Manual and keep it in the cab.
