When I look at the numbers from our 2021 equipment maintenance year, I still feel a little embarrassed. But I'm sharing this because if you're about to buy construction equipment—especially your first Liugong wheel loader or mini excavator—you can avoid the exact mistakes I made.
Background, in case it helps: I'm an office administrator for a 28-person construction company. I handle everything from office supplies to equipment service contracts—roughly $150,000 in annual purchase orders across 11 vendors. I report to both operations and finance. Heavy equipment was never in my job description. But in May 2020, our operations manager handed me a set of keys and said, "You're the one who works with vendors. Figure it out."
Figure it out. Right.
In March 2021, I got an annual service summary from the dealer that maintains our Liugong equipment. Total: $18,400. That was 40% higher than the prior year. For a fleet of two machines—a Liugong wheel loader (848H model) and a Liugong 9018F mini excavator—the number felt ridiculous.
Forty percent higher. No warning. No obvious cause. Just a long list of service visits, parts, and labor.
My first instinct was to blame the dealer. Classic vendor-blaming. I demanded a line-item breakdown, compared hourly rates against regional benchmarks, and matched every part number to Liugong's publicly listed prices (as of March 2021; verify current rates at liugong.com).
The dealer was charging exactly what they said they'd charge. Parts were fairly priced. Labor hours were logged correctly. No padding.
So why was the bill 40% higher?
The machines weren't breaking down more often. Both were under three years old. The dealer's rates hadn't gone up. The answer, I eventually realized, had nothing to do with the equipment. It was me. Specifically, it was the "Are You Smarter Than a 5th Grader?" questions I never thought to ask.
The show works because it reminds you that fundamentals are the easiest things to skip and the most expensive to miss. Most adults can't name the capital of Montana (it's Helena, by the way). But we all assume we know enough about the things we buy.
With heavy equipment, I assumed the dealer would tell me what I needed to know. I assumed the sales process would surface everything important. The conventional wisdom is that when you buy a Liugong wheel loader or a Liugong 9018F mini excavator, the decisions that matter are bucket size, cab comfort, financing, attachments. That's what the brochures highlight and what the sales rep wants to talk about.
Most buyers focus on those things and completely miss the maintenance ecosystem. I was one of them. In practice, the questions that ended up costing me thousands were the ones a smart 10-year-old would ask:
"How do you fix it when it breaks?"
"What tools does the workshop need?"
"Where do the parts actually come from?"
I didn't have good answers to any of those when we took delivery. Here's what happened.
Let's start with the dumbest thing I did. The 848H is a full-size wheel loader. Its tires are roughly five feet tall. They need a serious volume of compressed air, and the pressures involved are closer to what a heavy truck uses than a passenger car.
Our old shop compressor had died just before the loader was delivered. My lead mechanic asked me to order a replacement. I priced a proper 30-gallon compressor at around $700. Then I saw a 12V air pump online for $140. The product title said "heavy duty" and "120 PSI max." I thought I was being efficient. I was being cheap.
The pump died on the third use. We were inflating a loader tire—still nowhere near target pressure—when the motor just quit. It never turned on again. We checked the fuse, the wiring, everything. The pump was a paperweight.
That failure cascaded in the most expensive way possible. We couldn't reliably top off or measure the tire pressure, so the 848H ran underinflated for weeks. The tire wore unevenly, cracked along the sidewall, and had to be replaced. $1,680 for the tire, mounting, and a mobile service call. I then ordered the $700 compressor. Lesson learned: "an air pump" and "the right air pump" are not the same thing.
Second basic question: what does it actually take to repair this machine in the field?
The Liugong 9018F mini excavator is a 1.8-ton machine. Small enough to move on a trailer, strong enough to dig a foundation. When it developed a hydraulic leak in the drive area, the service manual said the repair required lifting a drive motor assembly out of the undercarriage. The assembly weighed about 180 pounds.
We had an engine hoist. A 1-ton unit. Bought back when someone thought we'd be pulling truck engines in our spare time. My lead mechanic took one look and said, "We don't have the right setup for this."
I insisted we try. That was my mistake.
We rolled the hoist over and started lifting. The front casters sank into the gravel before we got the assembly four inches off the ground. We slid plywood under and tried again. The hoist wobbled sideways. The chain was at an angle because the boom couldn't reach properly. My mechanic stopped, lowered the assembly, and gave me a look that still haunts me.
We called the dealer. The field service tech arrived with a portable lifting frame designed for undercarriage work. He had the drive motor out in thirty minutes. The whole repair took three hours. No wobbling. No gravel. The invoice: $620.
Here's what gets me: a proper 2-ton engine hoist costs around $400. The 1-ton unit we had cost $250. The difference between a $250 tool and a $400 tool cost us $620 in one day, plus one round of avoidable downtime.
Third basic question: parts availability. When we needed a hydraulic filter for the 9018F, I ordered it from our regional Liugong dealer, 45 miles away. I expected next-day delivery. It took five days.
The filter wasn't in stock at the branch. It came from a central warehouse, and that warehouse shipped on a fixed weekly cycle. The order went in Thursday, got processed Friday, sat over the weekend, and arrived Tuesday. For a sixty-dollar part, our excavator sat idle for five days.
The dealer wasn't wrong. The price was fair, the process was normal, and the lead time is probably standard across the industry. My mistake was assuming "dealer nearby" meant "parts instantly available." Nobody asked me whether I'd verified that. I should have asked: What does the dealer stock locally? What's the lead time for non-stock items? Which consumables should we keep on our own shelf?
The correct answer would have been: keep two hydraulic filters and an air filter on the shelf. Cost: about $120. Value: avoiding five days of a machine sitting dead during a job.
Let me put the damage in one place:
That's $2,620 in direct charges. The five days of 9018F downtime added at least $1,400 in crew inefficiency and schedule disruption. Then there were the extras—two emergency parts runs, shipping fees, and the hours I spent on the phone. You're at about $5,000, and I'm being conservative. Our maintenance bill went up $5,200 year-over-year. Nearly all of it traced back to questions I didn't ask before the equipment arrived.
My VP didn't yell. He just asked why a tire on an 18-month-old loader was already shot, and why a sixty-dollar filter took five days, and why we kept paying for service calls. There were no good answers. That was worse than yelling.
The fix was embarrassingly simple. I sat down with the service manager at our Liugong dealer, told him I didn't know what I didn't know, and asked for the basics. He walked me through their parts stocking logic, showed me the service schedule, and explained which repairs their customers typically do in-house versus which ones are better handled by a dealer. No upselling, no condescension—just answers. An informed customer asks better questions and makes faster decisions. I've become that customer.
If you're buying a Liugong wheel loader, a Liugong 9018F mini excavator, or anything similar, here's the 5th-grader checklist I wish I'd been handed:
Honestly, I'm still not sure why the sales process didn't surface any of this. My best guess is the sales rep assumed we had a fully equipped maintenance shop, and I assumed they'd tell me if I needed anything. That gap was expensive.
The machines were never the problem. The 848H and the 9018F have been reliable, and the Liugong dealer network has been solid—once we started asking the right questions. The problem was me, assuming the basics would take care of themselves.
Am I smarter than a 5th grader now? Probably not. But I now ask the simple questions before we buy or run anything: How is this maintained? What tools do we need? Where are the parts? Who fixes it when it breaks?
Those questions are free. Ignoring them cost us about $5,000 and one very awkward meeting with my VP. Ask them before you sign anything. Future you will be grateful.
