212 OPERATION
• 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 Volvo 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 AIRTEK™ front axle air suspensions, retorque
the U-bolts.
• Check the U-bolt torque on the Volvo air suspension at the end of the first
1600 km (1000 miles).
After the First 5000 Kilometers (3000 Miles) or Before 6400 Kilometers
(4000 Miles) or Before 3 to 4 Months
• Retorque the spring clip (U-bolts). (On REYCO suspensions, also retorque
the equalizer nut.)
Note:
On chassis equipped with AIRTEK™ front axle air suspensions, check the
torque of the front axle U-bolts at 24 000 kilometers (15,000 miles).
At the First A Inspection Interval
• Check front and rear axle alignment and adjust if the alignment is out of
specifications.
• Check steering knuckle to axle beam clearance.
Although this quality-built vehicle has been inspected, lubricated and adjusted
at the Volvo Trucks Assembly Plant, an occasional air, oil or coolant leak may
develop. Quick action to correct these minor items will prevent a major repair
later. Take the vehicle to the nearest Volvo service center as soon as any
abnormal condition becomes evident.
