Summer is here, and the heat is on across the country. With triple-digit temps and the rising heat index, it’s a challenge to keep you and your crew cool on the jobsite. It’s also hard on your service truck!

Tires, Brakes, and Batteries

Hot weather puts added stress on your truck, especially the tires, brakes, and battery.

If tire pressure is too low, the tire can sag because of how the sidewalls are flexing. This can weaken the rubber’s bond with the tire’s layers and lead to a blowout. Check your tires at least weekly using a quality digital gauge and inflate to the manufacturer’s recommended cold PSI, not what’s printed on the tire sidewall.

Brakes also struggle under high temps as friction between the pads and rotors decreases. To keep [...]

We are in the busiest stretch of the year for many service truck owners and downtime isn’t an option. Your hydraulic system is the muscle behind every job. That’s why routine fluid changes and component inspections aren’t just good practices, they’re essential to getting peak performance out of your truck.

Why Regular Fluid Changes Matter

Hydraulic fluid isn’t just a lubricant; it’s the lifeblood of your truck’s hydraulic system. Over time, this fluid degrades. Heat, moisture, and contamination from wear particles slowly break it down, reducing its ability to protect internal components.

Here’s what happens when fluid is ignored:

• Sluggish performance: Viscosity loss leads to poor pressure control.
• Increased wear: Contaminants act like sandpaper on valves and seals.
• Overheating: Degraded fluid can’t dissipate heat, stressing the entire system.

Changing hydraulic [...]

Your service truck is your mobile office, toolbox, or both — and keeping it clean and polished is more than just about looks. A well-maintained rig reflects your professionalism, protects your investment, and helps you spot issues before they become problems (hello, rust and wear).
