Make sure the tires are inflated to the manufactur-
er's specifications.
Remove all rocks or other material from the tread of
all tires that will be rotating on the dynamometer
rollers.
Make sure there is correct overhead clearance for
exhaust stacks, air deflectors, or other attachments
above the cab.
CAUTION
To prevent damage to the chassis dynamometer, there
must be some slack in the tension of the tie-down
chains.
Carefully position the vehicle on the rollers.
Attach the tie-down chains to the rear of the vehicle, and put
wheel chocks in front of the front wheels.
Adjust the vehicle and dynamometer room exhaust system
to make sure all exhaust gases are removed from the room.
Refer to the chassis dynamometer and vehicle manufac-
turer's recommendations and specifications for testing
procedures.
