Takeuchi TB370 Hydraulic Excavator Operators Manual (AQ2EN016)

Takeuchi TB370 Hydraulic Excavator Operators Manual (AQ2EN016) (SN 170000007-)

Running a TB370 all day in tight jobsites, on uneven ground and around utilities, you need to know exactly how it should behave when you crowd a trench wall, swing with a full bucket, or track over spoil. This operators manual helps you run the machine the way it was designed, spot bad habits before they cost you pins and hoses, and trace hydraulic issues when a function goes soft or drifts down. If, for example, your boom is slow when you’re benching out a foundation, this is what you’d use to verify control settings, check proper operating technique, and follow the valve and line routing before you start swapping parts.

Applications & Use Cases

Set up daily walk‑around checks so you catch leaks, loose guards, and track issues before they fail under load.
Understand control behavior when you’re lifting, swinging, or fine‑grading on a slope, and adjust your technique to reduce wear.
Verify safe pressure‑release steps before cracking any line or changing an attachment.
Route and clamp hoses correctly after repairs so they don’t rub through on the house or boom over time.

Safety Note

Always follow the manual’s shutdown and pressure‑relief procedures before inspecting or opening any hydraulic component.
