After the first 200 km (125 miles), retorque the wheel nuts using an accurately calibrated torque wrench. Recheck this torque again after 800 km (500 miles).
Check oil and coolant levels frequently.
Check brake and clutch adjustments per recommended maintenance schedule, and adjust as needed.
Observe the instruments often, and shut down the engine at the first sign of any abnormal readings.
Report all leaks, loose fasteners, unusual noises, etc., to the service representative at the nearest Mack dealership so they can be checked and corrected.
Check the spring clip torque (U-bolts). (On REYCO suspensions, also check equalizer nut torque.)
On chassis equipped with AIRTEKTM front axle air suspensions, retorque the U-bolts.
Check the U-bolt torque on the MACK air suspension at the end of the first 1600 km (1000 miles).
