Spring Prep Tips for Construction Equipment: Service for Roadbuilding and Municipal Fleets

Spring is when road construction fleets move out of winter survival mode and back into full production. Heavy construction machinery that performed reliably last fall can quickly run into trouble if winter contamination, corrosion and material residue aren’t addressed before startup. For machines like Falcon hot boxes, Gradalls, Vacalls, Power Curbers, Global Sweepers, Astec systems and Etnyre distributors, spring inspections are essential for reliability and safe operation.

A well-planned spring startup inspection can prevent multiple unplanned breakdowns once the season is underway, often saving days or even weeks of downtime across a fleet. We spoke with our service manager, Mandeep Dhillon, who witnesses this firsthand every spring: “Avoiding just one in-season failure can save thousands in lost labor, material waste and missed deadlines, especially for high-utilization construction equipment manufacturers like Etnyres, Gradalls, Falcons or Power Curbers.”

Clean your construction equipment: the foundation of spring readiness.

Thoroughly washing your construction machinery before inspection allows technicians to spot cracks, leaks, loose hardware and wear that might otherwise go unnoticed. Many critical spring tasks — like burner tuneups, spray calibrations, cycle time adjustments, leak inspections, track adjustments, belt alignments, roller inspections and greasing — simply cannot be done accurately on dirty equipment.

This is especially important because many of the following high-risk areas are difficult to access or inspect without proper cleaning:

• Burner chambers, air intakes and exhaust stacks
• Hydraulic hose ends, fittings and cylinder seals
• Electrical connectors, sensors and control enclosures
• Undercarriages, tracks, rollers and pivot points
• Material handling systems, such as belts, augers and chutes

Salt, moisture and fine aggregate trapped in these areas accelerate corrosion and wear once machines return to full operation.

Road construction equipment faces its own set of challenges. Asphalt and emulsion residue harden during colder months, restricting material flow. Aggregate dust and fines work their way into bearings, belts and cooling systems. Milling debris speeds up wear on moving components. Plus, grease points must be cleaned before lubrication to avoid contaminant buildup.

Mandeep recalls a recent case: “One of our customers brought in a Falcon hot box, reporting that the unit was not reaching the temperature set on the control panel. After diagnosis, we found approximately 1 inch of solidified material on the hopper floor, preventing effective heat transfer to the rest of the material. For Falcon units, it’s always recommended to clean the hopper box with BioPave after every use. And when equipment is running two shifts a day, semiannual burner service is often a better choice than waiting for the yearly interval.”

Proper cleaning opens the door to proper inspections. Below are the critical spring startup checks that depend on clean equipment:

Perform a complete preseason maintenance check.

After months of cold starts, moisture exposure and limited operation, the construction equipment needs more than a quick visual check. Many of the most frequent breakdowns are caused by being out-of-date with services.

Across road construction fleets, service teams often see the same issues surface at startup: hydraulic leaks and slow response times on Gradall units and Power Curbers due to dirt-packed fittings, valve banks or cycle times that are out of adjustment; inconsistent asphalt application rates on Etnyre distributors from clogged spray nozzles, residue in spray bars or calibration drift; reduced airflow and suction in Vacalls and Global Sweepers when debris builds up in fans, filters and ducting; and premature wear on belts, rollers and bearings in aggregate and stacker systems caused by hardened winter buildup.

Mandeep explains that when heavy equipment machinery comes in for spring preparation, the first step is reviewing operating hours to determine what preventive maintenance is required before the season starts:

1. The hydraulic system. It might need flushing or topping up. “We would check all the hoses for leaks,” Mandeep says, “make sure everything is clean and dry, check for greasing points and make sure all the pins and pivots, and the joints are greased accordingly so they do not run dry, which would cause issues down the road.”
2. Battery inspection. Cold weather takes a toll, so batteries are tested to confirm they still hold a charge and inspected for cracks, corrosion or leaks before heavy construction machinery is sent back into the field.
3. Oil analysis. If technicians spot signs of contamination during oil draining, that’s a clear signal to take a closer look at the hydraulic system. It gives both the service team and the customer clearer insight into the system’s health and enables them to determine whether further investigation or repairs may be needed before the season begins.
4. Fluids, filters and lubricants. These are handled following service intervals and machine hours, whether that’s at 250, 500 or 1,000 hours, depending on the construction equipment and the service manual. Staying on schedule with these basics helps systems run smoothly and reduces the risk of avoidable downtime once the season is in full swing.
5. Inspection of wheels, tracks and tires. Wheels, tracks and tires are also inspected for tears, uneven wear and low tread depth. Checking for uneven wear, proper pressure or tension and clearing out debris help prevent traction issues and unexpected failures once heavy machinery equipment is back in daily use. If you hear any unusual grinding noises, it is highly advised that you have your machine serviced.

Of course, beyond standard checklists, spring inspections are often guided by operators’ feedback. As Mandeep points out: “A machine may look perfectly fine on the outside, yet the crew on-site reports that it feels slow or isn’t performing the way it should. In these cases, experience matters. The service team knows which systems to test and where problems tend to hide. Technicians will connect gauges and verify that hydraulic pressures are within specification. When they’re not, the issue may point to a failing hydraulic pump or motor, or a pressure relief valve that isn’t operating correctly.”

Review your paperwork.

For municipal teams and contractors, the service manual should always be the starting point. This outlines maintenance requirements from construction equipment companies specific to each make and model, including seasonal service recommendations and the types of products you should use. Following procedures specific to your heavy equipment machinery is generally more effective than a general approach.

Just as important is keeping a clear service history. Having records of completed work, replaced parts and any issues that came up along the way makes it much easier to spot patterns over time — what holds up well, what tends to fail early and when it might be time to adjust a maintenance routine.

Test before you’re back on the job.

A quick test in the yard helps identify problems early, before they turn into bigger issues on the job. And if something doesn’t perform the way it should, reach out to a trusted dealer as soon as possible to help minimize delays. Our service team can assist with inspections, repairs and adjustments to get machines back to work quickly.

After completing spring inspections, technicians typically run all systems through onboard diagnostics and perform a short test startup to confirm everything operates as it should.

Plan spring service before the season peaks.

Spring is the busiest time of year for construction equipment, especially for roadbuilding and infrastructure work. Once projects ramp up, unplanned breakdowns can quickly turn into scheduling challenges and lost productivity, often at the worst possible time.

Planning service in advance allows maintenance and inspections to be handled on your timeline, helping fleets stay productive when it matters most. If you’re preparing for the season or have questions about spring inspections or maintenance, Amaco’s service team is available to help you prepare for the busy months ahead and keep your heavy equipment machinery moving when it matters most.
