Komatsu GD705-5 Motor Grader Operation and Maintenance Manual PEN00687-06 – Serial 26001 & Up

Description

Komatsu GD705-5 Motor Grader Operation and Maintenance Manual

This is the complete Operation & Maintenance Manual for the Komatsu GD705-5 motor grader, published under document number PEN00687-06 and covering machines from serial number 26001 and up. It is the same reference material Komatsu issues with the machine, giving operators and maintenance personnel everything needed to run, service, and troubleshoot the GD705-5 safely and correctly across the full service life of the grader.

The manual is written for the GD705-5 powered by the Komatsu SAA6D114E-3 diesel engine, with an operating weight of 19,310 kg (42,579 lb) including a 75 kg operator, and a 408-liter (108 US gal) fuel tank. Everything inside — the safety warnings, the pre-start checks, the gearshift and articulation procedures, the maintenance intervals, the torque values — is specific to this serial range and configuration, so the information matches the machine rather than a generic grader.

Beyond the chapter list, this GD705-5 manual works as a complete working reference for the machine. The operation section walks the operator through the daily ritual — walk-around inspection, fluid level checks, pre-start checks — then hands off to the procedures for starting the engine in normal and cold weather, moving off in either Manual mode or Torque Converter Auto mode, articulating and leaning for tight turns and slope work, and setting the blade into the various working postures (bank cut, shoulder reach, V-ditch digging left or right). The maintenance side is equally detailed, organised by service interval from the initial 250-hour break-in service through to the 8000-hour major service, with each procedure listing capacities, tightening torques, and step-by-step methods.

The troubleshooting chapter is where many owners end up first, and this manual covers the scenarios that actually happen in the field: running out of fuel and bleeding the system, a damaged leaning pipe, a flat battery and how to boost-start correctly, gearshift lever trouble, and the failure codes the machine monitor displays. Combined with the action code table (E01, E02, E03) and the method for reading a failure code, a technician can often diagnose a fault before calling a dealer.

What This Manual Enables You to Do

With this Komatsu GD705-5 Operation and Maintenance Manual on hand, an owner-operator or shop technician can perform the full range of routine and scheduled maintenance without waiting on dealer availability, from engine oil and filter changes at 500 hours to hydraulic tank servicing at 2000 hours and major service at 8000 hours. It supports correct adjustment of the circle guide clearance, toe-in, front wheel bearing play, ball joint clearances, and the disc brake wear check — the adjustments that keep a grader cutting straight and holding grade. It also enables safe operation in the field: knowing which articulating angles are permitted at which speeds, when to use Manual versus Torque Converter Auto mode, how to set the bank cut and shoulder reach postures, and how to respond if the engine stops on a slope or the brakes give trouble.

Correct procedures and the correct torque and clearance values matter on a machine like the GD705-5. A grader that is mis-adjusted will cut unevenly, wear tyres and circle components prematurely, and can put the operator at risk on slopes or near high-voltage cables. Having the exact Komatsu specification in front of you — rather than a generic repair guide or guesswork — is what separates a proper service job from one that costs you again a month later.
