Komatsu GD825A-2 Motor Grader Operation and Maintenance Manual (SEAM001700)

Out on haul roads or big cut-and-fill jobs, this GD825A-2 grader is usually shaping long stretches of compacted material and holding grade under heavy traffic. This Operation and Maintenance Manual is what I keep handy to set a solid service rhythm and keep the machine predictable day after day. When, for example, the blade starts chattering or steering feels heavier than usual, I use this book to trace whether it’s an adjustment issue, a lubrication miss, or an operator habit before it turns into downtime.

Applications & Use Cases

Plan preventive maintenance so filters, wear points, and critical linkages are inspected before they cause failures.
Set a daily/weekly walk-around routine to catch leaks, loose hardware, and cutting-edge wear early.
Verify operating practices for grading on slopes or in dusty conditions, so the machine isn’t overworked.
Isolate early warning signs like sluggish hydraulics or odd noises and decide if you can finish the shift or need to stop.
Coordinate shop and field work, aligning scheduled services with production windows to minimize lost hours.

FAQ

Q: Can I use this manual on a tablet in the cab?

A: Yes, as long as the file opens clearly and you can zoom diagrams, it’s fine for quick checks between passes.

Q: Is it worth printing parts of this manual?

A: I’d print the routine checklists and service schedules, laminate them, and keep them in the service truck or site office.

Safety Note

Always follow the manual’s lockout, support, and engine shutdown steps before inspecting or servicing the grader.
