Develon DX270WMH-7 Material Handler Shop Manual (950106-03632_A_EN)
Out on scrap yards, transfer stations, or port piles, this DX270WMH-7 spends its life swinging heavy steel, loading trucks, and working over rough ground. This shop manual’s what you use when you’re past simple filters and greasing and you’re ready to tear into major components without guessing. Say the upper structure’s got a nasty slew knock: with this, you can plan the teardown, trace the play, inspect the bearings and gear teeth while it’s open, then reassemble without leaving a shim out or misaligning the swing motor.
Applications & Use Cases
- Strip and rebuild the boom, stick, and grapple circuits, then bleed and test the hydraulics so you don’t chase phantom air in the lines.
- Plan your workspace before a major teardown, so you’ve got stands, lifting points, and parts laid out where you can route and trace hoses cleanly.
- Check torque sequences when you button up the slew ring or final drives, then verify rotation and backlash before you put it back to work.
- Isolate electrical faults in swing, cab riser, or cooling fans by following proper test steps instead of just swapping parts.
- Inspect wear points while components are off the machine, so you catch cracked mounts, misaligned pins, or tired bushings early.
FAQ
Q: Is this a PDF I can search on my laptop or tablet?
A: Yes, it’s typically a searchable PDF, so you can jump to a system or term instead of scrolling page by page.
Q: Can I print just the sections I need for the jobsite?
A: You usually can; most folks print the systems they’re working on, stick them in plastic sleeves, and keep the full file on a computer.
Safety Note
Always support the upper structure and attachments with rated stands and blocks before you work underneath or loosen any major mounting hardware.
