Manitou MLA 628 Operators Manual – OEM Specs & Safety

If you run a shop that works on rough terrain forklifts, you already know the pain of chasing down a loose attachment or finding out the hard way that a decal was peeled off by some guy who thought he knew better. The Manitou MLA 628 Operators Manual is the original document that came with the truck – not a reprint, not a third-party summary. I’ve seen too many operators skip the safety pages and then wonder why the mast binds or the attachment drops. That happens when you don’t have the factory procedures in front of you. This 130-page manual is what Manitou North America put together for the MLA 628-120 LSU Powershift, Series 3-E2. It’s the same book that should be strapped to the truck by law.

Introduction to Safety – Why It Starts Here

Most guys flip right past the safety section. Don’t. The manual opens with a full section on general safety standards, safety messages (pages I through VIII), and safety decals. Page I outlines the general standards for rough terrain forklift operation – things like load capacity, stability, and operator training. The safety decal section shows exactly where each decal goes and what it warns about. Missing a decal? This is where you figure out which one to order. Page VII covers the safety message format – the signal words and what they mean. If you are training a new operator, have them read this section before they even sit in the seat.

Operating and Safety Instructions – What the Operator Needs

Pages 1-3 covers the operating and safety instructions. This is not a generic guide. It tells you how to start the 120 LSU Powershift engine, how to shift the transmission, and what to check on the instrument panel. It includes load handling procedures specific to the MLA 628’s mast configuration. Ignoring these instructions is a good way to bend a fork or tip the truck. Page 1-3 also lists the pre-operational checks – tire pressure, fluid levels, and brake function. I’ve watched guys skip the tire check and then fight a pull to one side all shift. Don’t be that guy.

Description – Know Your MLA 628

The description section (pages 2-3) gives you the layout of the machine. It identifies the major components: the powershift transmission, the hydraulic system, the mast assembly, and the controls. This is the part you reference when a customer asks ‘What is that thing under the floorboard?’ You’ll know because the manual shows it. The description also includes the machine’s serial number location and how to read the model plate. If you are buying a used MLA 628, this section helps you verify you are getting the right truck.

Maintenance – The Section That Keeps It Running

Maintenance on page 3-3 is short but packed. It covers daily, weekly, and periodic service intervals – oil changes, filter replacements, hydraulic fluid checks, and lubrication points. It lists capacities and recommended fluids. The manual does not give you arbitrary intervals; it tells you exactly when to service based on hours of operation. If you are doing a 500-hour service, you follow the procedures here, not some aftermarket booklet that says ‘use 10W-30’ when the factory calls for SAE 30. K-D Manitou D 2876 LE 401-405 Operators Manual – OEM Marine Diesel covers related powertrain specs if you are dealing with a swapped engine.

Picking Up Attachments – Page 4-3 Procedure

Page 4-3 is the attachment pickup procedure. This is where most field failures happen. People try to pick up a load with the forks angled wrong or use an attachment that isn’t compatible. The manual gives you the step-by-step for connecting and disconnecting attachments, including hydraulic couplers and locking mechanisms. It tells you how to align the mast and check the load center. I’ve seen a guy drop a 2,000 lb coil because he didn’t lock the carriage. The factory procedure would have prevented it. K-D Manitou D 2866 TUE Operators Manual – Factory Specs & Procedures has similar attachment data for another Manitou model, but this manual is the one for the MLA 628.

Source Authenticity – OEM vs Third-Party Manuals

This is an original OEM document distributed by Manitou North America. The part number is 547866AS, revision R11-10. Aftermarket manuals often skip the safety message section or rephrase the maintenance intervals. They might tell you to use a generic filter that doesn’t have the correct bypass pressure. This manual was written by the engineers who built the truck. It includes the factory decal placement, the original torque specs (though not listed in the operators manual – those are in the service manual), and the official operating limits. Operating Instructions MAN Industrial Diesel Engines D 2876 is another OEM manual if you are working on the engine itself. I trust OEM documents because they have not been altered by a third-party typesetter who couldn’t tell a torque wrench from a tire iron.

If you want to understand what a manual transmission is and how it differs from this powershift, the Manual Transmission and Manual Transmission articles explain the basic principles. But for the MLA 628, you need the factory powershift procedures.

Is this manual specific to the MLA 628-120 LSU Powershift?

Yes. It covers only the MLA 628 with the 120 LSU powershift transmission, Series 3-E2.

What if I lose the manual or it gets destroyed on the job site?

Replace it immediately. The manual must be kept in the lift truck per Manitou’s own statement on the cover page. Without it, you are operating blind on safety messages, decal locations, and proper attachment procedures. OSHA fines for missing manuals on forklifts are steep. This access gives you a digital copy you can print and laminate. Keep the original in the cab and a backup in your toolbox. I’ve had to chase down a replacement for a rusted-out manual on a Saturday afternoon – not fun. Having the PDF means you can reprint whenever it gets greasy.

Access the Factory Manual now and get the original Manitou MLA 628 operators document on your device. Your operators will have the safety instructions, the maintenance schedule, and the attachment pick-up procedure from the same people who built the truck. No guesswork, no reprints – just the OEM spec.
