(c) MEASURING POINTS FOR ON-VEHICLE BALANCER
(1) Jack up all 4 wheels with 2 post lifts.
(2) Fasten the vehicle by setting 2 pick-up stands in the
bottom of suspension arm's tip of the front wheels
or rear wheels to be measured.
(3) Support the vehicle with rigid racks so that vehicle
will not lean in the vehicle's front/rear direction.
(4) Release the parking brake.
(5) Check that no dragging force exists by turning each
wheel by hand.
(6) Set the wheel balancers.
(7) Measurement should be done by using both of en-
gine drive and wheel balancer roller drive.
NOTICE:

Start the engine, and then increase the vehicle speed
gradually in the D range.

Do not accelerate nor decelerate suddenly.

Deceleration should be done by brake gradually.

Take special care that the vehicle does not move.

Measurement should be done quickly.
10. FOR VEHICLES EQUIPPED WITH CATALYTIC CONVERTER
CAUTION:
If a large amount of unburned gasoline or gasoline vapors flow into the converter, it may cause ove-
heating and create a fire hazard. To prevent this, observe the following precautions.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid idling the engine for more than 20 minutes.
(c) Avoid a spark jump test.
(1) Perform a spark jump test only when absolutely necessary. Perform this test as rapidly as pos-
sible.
(2) While testing, never race the engine.
(d) Avoid a prolonged engine compression measurement.
Engine compression measurements must be performed as rapidly as possible.
(e) Do not run the engine when the fuel tank is nearly empty. This may cause the engine to misfire and
create an extra load on the converter.
