Manitou MLT 634-120 LSU, MLT 634-120 LSU PS, MLT 735-120 LSU 2011 Operators Manual

Listen, if you’re running a MLT 634-120 LSU, MLT 634-120 LSU PS, or MLT 735-120 LSU on a job site, the manual that came with the machine is supposed to stay in the cab. But they get lost, torn up, or left in the rain. You end up guessing approach angles, fluid specs, or load limits. That’s how you bend a jib or blow a hydraulic line. This 2011 OEM operators manual keeps you from being that guy. 154 pages, printed by Manitou, not some third-party reprint outfit. It’s the same booklet that shipped with the telehandler when it rolled out of Ancenis, France.

Instructions to the Company Manager: Who Is Responsible?

Section 1 of this operators manual spells out exactly what the site manager, the operator, and the lift truck each carry. Page 3 lists the five headings under “Instructions to the Company Manager” — THE SITE, THE OPERATOR, THE LIFT TRUCK, THE INSTRUCTIONS, THE MAINTENANCE. Miss any one of those and you’re not compliant with European CE directives or common sense. If you’re in Australia, the specific supplement (Section 5) tailors those rules to local regulations. Don’t ignore the “EC” Declaration of Conformity either — that’s your legal cover if an inspector shows up.

Lubricant and Fuel Levels: The Actual Specs

You need to know which oil goes in the hydraulic tank, what fuel grade the Deutz engine expects, and the intervals for changing filters. The manual dedicates a full subsection to LUBRICANT AND FUEL LEVELS under Maintenance Instructions. It cross-references the SERVICING SCHEDULE starting at A – DAILY OR EVERY 10 HOURS SERVICE, then B (50 hours), C (250), D (500), E (1000), F (2000), and G for occasional maintenance. That schedule tells you exactly when to pull the jib safety wedge and when to check the bucket pins. No guesswork.

Dimensions and Load Charts: Why You Need Them

The MLT 634-120 LSU Série G-E3 and the MLT 735-120 LSU Série 7-E3 have different reach and lift capacities. The manual includes separate DIMENSIONS AND LOAD CHART pages for each variant. If you try to lift a 3-ton load at full boom extension on a 634 without checking the chart, you’re asking for a tip-over. The chart tells you the max load at each boom angle and extension. That’s not in the salesman’s brochure — it’s on page [DATA NEEDED] of this manual. Keep that page visible in the cab.

Manitou Original Spare Parts and Equipment: Why It Matters

Section 3 lists FILTERS CARTRIDGES AND BELTS with part numbers and cross-references to original Manitou components. Aftermarket hydraulic filters can cause cavitation or seal failure. This manual gives you the exact OEM part numbers so you order the right stuff from your dealer. It also includes a START-UP CHECKLIST — a pre-flight rundown you should run every morning. Skip it and you miss a low coolant level or a chafed hose that turns into a $2000 repair.

Does This Manual Cover the MLT 634-120 LSU PS Variant?

Yes. Section 2 includes a dedicated CHARACTERISTICS page for the MLT 634-120 LSU PS Série G-E3. The PS variant has different tire specifications — FRONT AND REAR TIRES are listed separately with inflation pressures. If you’re running a PS (probably “Power Shift” or a specific option package), don’t assume the standard 634 specs apply. The manual tells you the exact differences.

Picking Up Attachments: Procedure, Not Guesswork

Section 4 covers ADAPTABLE ATTACHMENTS. It walks through PICKING UP THE ATTACHMENTS — the sequence of hydraulic engage, locking pins, and safety checks. It also lists TECHNICAL SPECIFICATIONS OF ATTACHMENTS and ATTACHMENT SHIELDS. If you’re swapping from forks to a bucket or a bale handler, read that section first. I’ve seen guys shear off attachment pins because they didn’t align the quick-coupler properly. The manual prevents that.

FAQ

Will this manual work for the MLT 735-120 LSU Série 7-E3?

Yes. The manual includes a separate CHARACTERISTICS and DIMENSIONS AND LOAD CHART section specifically for that model.

Does it include the “Specific Australia” supplement?

Yes. Section 5 is titled “SPECIFIC AUSTRALIA” and references supplement 647065 AU. If you operate in Australia, that section covers local compliance and labels.

Are the electronic controls covered in this operators manual?

This is an operator’s manual, not a full service manual. It covers daily operation, safety, load charts, and basic maintenance. For hydraulic troubleshooting or ECU diagnostics you’d need the corresponding shop manual. That said, it does have a section on INSTRUMENTS AND CONTROLS that explains the dash readouts and joystick functions.

How many pages and what year?

154 pages, publication date 18/11/2011. Original print from Manitou France. Part number 647387EN.
