Daily Pre-Operation Checklist

Complete these checks before starting your Dump Truck every day.

1
Engine Oil Level SAFETY CRITICAL
Check the dipstick to ensure the oil level is within the recommended range. Low oil can cause serious engine damage.
2
Coolant Level SAFETY CRITICAL
Inspect the coolant level in the radiator or expansion tank. Top off as needed with the correct coolant mixture.
3
Hydraulic Fluid Level SAFETY CRITICAL
Check the hydraulic fluid reservoir level. Low fluid can affect the operation of the dump bed and other hydraulic systems.
4
Tire Condition and Pressure SAFETY CRITICAL
Inspect tires for cuts, bulges, and uneven wear. Check tire pressure and inflate to the recommended PSI. Underinflated tires increase the risk of blowouts.
5
Brake System SAFETY CRITICAL
Test the brakes to ensure they are functioning properly. Listen for unusual noises and check for excessive travel in the brake pedal.
6
Lights and Signals SAFETY CRITICAL
Verify that all lights (headlights, taillights, brake lights, turn signals) are working correctly. Replace any burned-out bulbs.
7
Steering System SAFETY CRITICAL
Check for excessive play in the steering wheel and listen for unusual noises while steering. Report any issues immediately.
8
Windshield and Mirrors SAFETY CRITICAL
Ensure the windshield and mirrors are clean and free of cracks or damage. Good visibility is essential for safe operation.
9
Dump Bed Operation SAFETY CRITICAL
Cycle the dump bed up and down to ensure smooth operation. Check for leaks in the hydraulic cylinders and hoses.
10
Horn SAFETY CRITICAL
Test the horn to ensure it is working properly. The horn is an important safety device for warning others.
11
Fluid Leaks SAFETY CRITICAL
Inspect the engine, transmission, hydraulic system, and axles for any signs of fluid leaks. Address leaks promptly to prevent damage.
12
Air Filter
Check the air filter restriction indicator. If indicated, inspect the air filter and clean or replace it as needed.
13
Safety Devices SAFETY CRITICAL
Ensure seatbelts are in good working order and that the backup alarm is functioning correctly.

Pro Tips from the Field

Wisdom from experienced Dump Truck operators.

1

Always use the correct grade and type of fluids for your dump truck. Refer to the manufacturer's specifications.

2

Grease all fittings regularly to prevent wear and corrosion. Pay special attention to suspension and steering components.

3

Inspect tires frequently for damage and wear. Maintain proper tire pressure to maximize tire life and fuel efficiency.

4

Keep the engine clean to prevent overheating. Remove any debris that may accumulate around the radiator and engine block.

5

Listen for unusual noises while operating the dump truck. Investigate any strange sounds promptly to prevent minor problems from becoming major repairs.

6

When possible, avoid overloading the dump truck. Overloading can damage the suspension, tires, and other components.

7

If you operate in dusty conditions, inspect the air filter more frequently and clean or replace it as needed.
