Komatsu D58E-1 Operator Manual – 163 Pages of Factory Procedure

I’ve seen operators crack a final drive because they skipped the warm-up procedure in the manual. I’ve watched a dozer roll because someone thought “the parking brake is close enough.” That’s why you need this manual — the actual 163-page factory operator’s manual from Komatsu for the D58E-1, D58E-1 A, D58E-1 B, D58P-1, and D58P-1 B. Not a reprint. Not a translation of a translation. This is the original PDF that came off Komatsu’s server, with every safety label position, every control diagram, and every ambient-temperature oil chart that the factory intended.

Safety Information: The Section You Cannot Skip

Chapter 2 is Safety Information. Chapter 3 is General Precautions, then Precautions During Operation, then Precautions for Maintenance. That’s eight subsections of hard-won lessons from people who designed this crawler. Things like: never start the engine before checking the brake accumulator pressure, keep the battery terminals tight, and never tow a D58E-1 without the proper tow pin. I’ve seen a guy try to yank one with a chain on the blade brace — the brace snapped and the chain came back through the cab. That’s the kind of thing the manual prevents. Page 26 of the safety section (the PDF page numbering) lists the exact position for every safety label on the machine. If you’re re-lettering a machine or buying a used one with peeled stickers, that page alone is worth the price. You want to run a safe shop? Start here.

163 Pages of Factory-Proven Procedures

One hundred sixty-three pages. That’s what you get. Not a 40-page pocket guide that skips the cold-weather section. The book covers: general view of controls and gauges (section 10.2), fuse box location (11.4), shifting gear (12.5), steering (12.7), tips for longer undercarriage life (12.16), loading and unloading for transport (13.1), cold-weather precautions (14.1), long-term storage (15.1–15.3), troubleshooting after running out of fuel (16.1), if battery is discharged (16.2), wear parts list (19), and the ambient-temperature lubricant chart (20). Every single one of these sections tells you what Komatsu wants you to do, not some aftermarket writer’s guess. For example, section 20 lists which hydraulic oil grade to run at -20°F vs 100°F. That’s the difference between a pump that lasts 5000 hours and one that grenades at 500.

Understand the Controls Before You Start

Section 11 breaks down every meter, lamp, switch, lever, and pedal. It tells you what the torque converter oil temperature gauge should read, what the transmission oil pressure warning light means, and how the steering clutches and brakes work together. If you’re handing this machine to a new operator, have them read pages 10.1 and 10.2 first. The general view drawing shows where the hydraulic lock lever is, where the parking brake is, and where the fuse panel lives. I’ve had techs call me asking why a D58E-1 won’t move — it was the lock lever. That’s in the manual. The answer was right there.

Cold Weather Operation: Why You Need This

The manual devotes a full chapter — Chapter 14 — to cold-weather operation. It covers pre-heating the engine, using the proper coolant mixture, and what to do after completion of work to prevent frozen components. There’s even a separate subsection on after cold weather (14.3) — thawing out air cleaners, checking for ice in fuel lines. If you operate in the northern tier states, this section alone can keep the dozer running when the temperature drops below zero. Pair it with the ambient-temperature chart in section 20 to pick the right oil for the season.

Why an OEM Operator’s Manual vs Aftermarket?

Aftermarket manuals get the torque values wrong. They skip the safety labels. They use generic drawings that don’t match your exact serial number range. This manual covers the D58E-1, D58E-1 A, D58E-1 B, D58P-1, and D58P-1 B — specific models with specific add-ons (the -A and -B suffixes indicate factory updates). The OEM document includes the serial number table and distributor information in section 4. If you need to order parts, you’ll have the exact model and serial number to give the dealer. For context on heavy equipment documentation standards, see Automotive Industry Overview. And for understanding the diesel engine that powers this machine, check Internal Combustion Engine. But for this machine, use the factory file.

FAQ

What safety precautions are listed in this manual?

The manual dedicates sections 2 through 8 to safety — general precautions, before starting engine, during operation, towing, battery handling, and maintenance safety. It also includes the exact positions for all safety labels on the machine (section 9). If you’re missing a decal, you can order the right one based on this diagram.

How many pages does the manual have?

163 pages.

Does it cover what to do if the battery is dead?

Section 16.2 covers a discharged battery — jump-start procedure, booster battery connections, and safety warnings about explosive hydrogen gas. It also tells you the correct battery capacity (CCA rating) for cold weather.

Can I use this for maintenance and wear parts?

Section 18 outlines service intervals for oil, fuel, and coolant. Section 19 is a wear parts list (belts, hoses, filters, cutting edges). Section 20 tells you which lubricant to use based on ambient temperature. For maintenance, you still need the separate service shop manual with torque specs, but this operator manual is required reading before you turn a wrench.

Access the Factory Manual from the product page. Put it on the tablet in the cab. Print the safety section and tape it to the inside of the door. Your machine will last longer, and so will you.
