7 Signs of a Well-Maintained Used Machine

Every seller says their machine was "well maintained." A few minutes of looking in the right places tells you whether the machine agrees.

Signs you can see in five minutes

One: service records — even a grease-stained notebook beats a perfect memory. Two: fluids — engine oil should not smell burnt, hydraulic oil should not look milky, coolant should not float rust. Three: consistent wear — pedals, seats and levers should match the hour meter; a shiny 2,000-hour seat on a worn 10,000-hour pedal means someone swapped parts or wound the clock. Four: original paint in the hidden places — inside panels and under covers, fresh overspray is a repaint confession.

Signs that need a test run

Five: cold start — a healthy engine catches quickly without a cloud of blue or white smoke. Six: full-travel function test — every axis, every cylinder, to the end of stroke, under load where possible; problems hide at the extremes. Seven: leaks after shutdown — walk away for ten minutes, come back, and look underneath. A dry pad under a warm machine is the best maintenance certificate there is.

None of these checks needs special tools — just the discipline to do all seven before the price discussion starts.
