When the vehicle is new, maintenance is frequent, with even minor issues prompting a visit to the service station. However, as the two-in-one tow truck gets older, attention to maintenance often decreases. In fact, the maintenance frequency should increase with the vehicle’s age. For example, a new truck might need servicing every 5,000 kilometers, but a 10-year-old truck should be serviced every 1,000 kilometers. This explains why vehicles over six years old require annual inspections.
Second: Turning the Steering Wheel to the Limit
During driving lessons, instructors sometimes ask learners to turn the steering wheel fully to improve precision. Many drivers retain this habit, even turning the wheel more forcefully. This can damage the tow truck because it increases wear on the steering system’s ball joints and tie rods. For vehicles with power steering, turning the wheel to the limit causes the power pump to output maximum fluid flow to the steering gear, increasing the internal oil pressure and temperature, which can lead to damage or leaks.
Third: Stomping on the Brake Pedal
Many drivers accelerate and brake hard. Two-in-one tow trucks use either disc or drum brakes. Disc brakes generate braking power through friction between the brake pads and disc, and brake pads are wear items. Frequently stomping on the brakes can significantly shorten the lifespan of the brake pads. For drum brakes, frequent hard braking can cause overheating and brake failure, compromising safety. Therefore, hard braking should only be done when absolutely necessary, and regular driving should prioritize gentle braking.
Fourth: Accelerating on Uneven Roads
Many tow truck drivers drive aggressively, not slowing down for speed bumps or potholes. Accelerating on rough roads can affect wheel alignment, causing the tow truck to veer off course or reduce tire lifespan. It can also damage the suspension and sometimes scrape the chassis or even damage the engine.
Fifth: Carelessly Driving Over Curbs
Driving over curbs is a major cause of tire damage. According to Hankook Tire’s statistics, 70% of tire damage in China is due to vehicles driving over curbs. Especially driving sideways onto curbs can easily cause tires to burst.
Sixth: Continuing to Drive After the Fuel Warning Light Is On
When the fuel warning light of a tow truck turns on, it means the fuel tank is almost empty. Experienced drivers know that the truck can usually travel several dozen kilometers with the remaining fuel. Many modern vehicles have fuel pumps installed at the bottom of the fuel tank, relying on fuel for lubrication and cooling. If the fuel level is too low, the fuel pump cannot be properly lubricated and cooled, easily causing damage to the pump.
By avoiding these bad driving habits, you can prolong the life of your two-in-one tow truck and ensure safer operations.
