Premier Engineering & Manufacturing MT35P12 Service Manual

I’ve seen too many guys tear into a deicer with a generic manual and a prayer. That’s how you snap a boom pad bracket or fry the fuel pump controller. This Premier Engineering & Manufacturing MT35P12 Service Manual is what you need on the bench. 599 pages of OEM information straight from the manufacturer – not some photocopied aftermarket mess. Premier Engineering & Manufacturing built these machines in Marinette, Wisconsin, and they know where every bolt goes and why. If you’re responsible for keeping an MT35P12 “EXPRESS HEAT” deicer running, stop guessing and start using the documentation the factory wrote.

General Information and Operating Instructions

Chapter 1 lays out the basics: unit identification, safety decals, fluid capacities, and pre-start checks. It tells you how to operate the deicer without burning up the heat exchanger or overloading the fuel pump. I like that the manual follows ATA 101 standards – the same layout used for ground support equipment. You get the nomenclature and functions before you ever turn the key. Page 2 has the introduction and contact info for Premier Engineering & Manufacturing if you need something they didn’t print. That’s rare, but good to have.

Deicer Maintenance Procedures

Chapter 2 covers routine maintenance: lubrication points, filter changes, heater inspections, and fuel system checks. The manual lists part numbers for items like the Carter PAC70 fuel pump and the flow switch (109449-009). You won’t have to call around guessing which Carter pump fits – it’s right there. For fleet mechanics who run multiple units, having these numbers in one place saves hours. The torque specs for mounting bolts aren’t printed in Chapter 2, but you’ll find them in the Manufacturers’ Appendix. Don’t assume – look it up.

Major Repair: What You Need to Know

Chapter 3 is where the serious work happens. Overhaul procedures for the engine, hydraulic system, and deicing fluid circuit. If you’ve ever had a boom pad bracket fail (part 991036-090), you’ll find the replacement procedure and the exact bracket weight – 1990 pounds on that one. The manual tells you the correct supporting points and lifting methods. Safety warnings in this section are not suggestions. I’ve seen guys skip the lockout procedure and get a hot oil bath. This chapter keeps your eyebrows intact. And if you need wiring diagrams or hydraulic schematics, they’re in the appendix. That’s how an OEM manual works – you don’t hunt for loose pages.

Illustrated Parts Lists: Why They Matter

Chapter 4 gives you exploded views with callouts. Every bushing, seal, and fastener has a part number. For the MT35P12, Premier Engineering & Manufacturing includes the SW H – 992102-001 (commercial part number) and the bracket 08-18005. When you order parts, you order exactly what the factory intended. No aftermarket cross-references that might slip. I’ve had techs try to substitute a 170-pound fuel pump with a lighter unit – that causes cavitation and heater failure. The parts list prevents those mistakes.

Manufacturers’ Appendix: The OEM Source Data

Chapter 5 is the gold mine. This appendix contains specifications from the original component manufacturers: flow switch specs, temperature switch set points (109449-001), fuel valve torque values, and the preheat valve adjustment procedure. Page 3 includes the important notice about using proper service methods – it’s a legal and safety reminder. But the real value is the tables: diesel fuel heater purge values, fan part numbers (123-190-073), and the hot air purge sequence. If you’re troubleshooting a burner that won’t light, these appendix pages tell you exactly what the sensor should read. Compare that to a third-party manual that says “check the fuel system.” No help at all.

Does This Manual Cover the Fuel System?

Yes, and thoroughly. The fuel pump (Carter PAC70), fuel valve (123-190-015), temperature switch, and preheat valve are all detailed. The flow switch (109449-009) and its testing procedure are in Chapter 3. You get the fuel pump fan assembly, the diesel fuel grade recommendations (No. 2 diesel), and the heater purge cycle. For anyone working on ground support equipment, this is the only manual you should trust. I’ve seen aftermarket docs skip the flow switch testing – that’s how you get a deicer that sprays cold fluid on an aircraft wing. Not on my watch.

Why OEM Documentation Beats Aftermarket

Aftermarket publishers reprint generic procedures and hope they fit. This manual was written by Premier Engineering & Manufacturing for the MT35P12. The part numbers match the machine. The torque values come from the factory floor. The wiring diagrams show the actual wire colors and connector pinouts. When you buy a copy from AutoRepairManuals, you get the exact PDF of the original document – 599 pages, no missing sections, no compression artifacts. Compare that to a scanned third-party copy where the schematics are illegible. That’s not a manual; that’s a frustration aid.

If you also maintain other equipment, take a look at White Outdoor LT-5 – 700 Series Rider Service Manual for mowers, or the Maruti MB308 Service Manual Procedures and Repair – Section: Section 8A Wiring D for electrical diagnostics, and the HUSKIE Hydraulic Hammers Service Manual for hydraulic breaker work. Each of those manuals follows the same OEM-first philosophy.

For understanding basic transmission theory, the Manual Transmission article on Wikipedia is a decent primer, but it won’t help you with the MT35P12’s PTO drive. If you need a deeper dive into transmission function, I’d also read the Manual Transmission page for general knowledge. Still, for this deicer, you need the factory manual.

Frequently Asked Questions

Does this manual include torque specifications for the fuel system?

Yes, torque values for fuel valve and pump mounting bolts are in Chapter 5 Manufacturers’ Appendix. Specific numbers aren’t listed in the OCR excerpt, but the appendix contains tables for each component.

Can I use this manual for a different deicer model?

No. It’s specific to the MT35P12. Other Premier models have different hydraulic circuits and control logic.

What if I need a part number that isn’t in the Illustrated Parts List?

Call Premier Engineering & Manufacturing at (715) 735-6440. They have decades of documentation and can look up superseded numbers. The manual gives you the contact on page 2.

Is the manual in color?

The PDF is black-and-white for the text and line drawings. Wiring diagrams and schematics are clear but monochrome. That’s standard for factory manuals – no glossy pages needed.
