INTRODUCTION
IDENTIFICATION LABELS
• Observe the instruments often, and
shut down the engine at the rst 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.
Although this quality-built vehicle has
been inspected, lubricated and adjusted
at the Mack Trucks Assembly Plant,
occasional air, oil or coolant leaks
develop. Quick action to correct these
minor items prevents major repairs later.
Take the vehicle to the nearest Mack
service center if an abnormal condition
becomes evident.
Initial Valve Adjustment Intervals
Refer to the Maintenance and
Lubrication section for detailed
information concerning the Initial Valve
Adjustment Interval.
Temporary Loss of Power
Output
When driving in difcult driving
conditions e.g. high temperatures, high
engine speeds and high loads, the
temperature in the exhaust system may
become abnormally high. This could
activate the engine's protection system.
The engine's power output is reduced
temporarily. The power output is
restored to normal performance when
the temperature has dropped.
Contact an authorized Mack dealership
if the engine power output is not
restored.
VIN Locations
The Vehicle Identication Number (VIN)
is displayed in three locations (a frame
rail stamping and a label). The 17-digit
VIN must be identical in all locations.
The VIN frame stamping is located on
the right outside frame rail and the left
inside frame rail.
