Caution: One or more of the following guidelines may apply when performing specific required tests in the work stall:

1. When a test requires spinning the drive wheels with the vehicle jacked up:

•	On vehicles equipped with a limited-slip differential, do not attempt to spin one drive wheel with the other wheel on the ground. The vehicle may drive through this wheel and cause the vehicle to move unexpectedly, or drive off the safety stands. This may result in personal injury or damage.

•

Do not exceed 56 km/h (35 mph) when spinning one drive wheel with the other drive wheel stopped. This limit is necessary because the speedometer indicates only one-half the actual wheel speed under these conditions. If all drive wheels are spinning at the same speed, do not exceed 112 km/h (70 mph). Personal injury may result from excessive speed wheel spinning. All persons should stay clear of rotating components and balance weight areas to avoid possible personal injury.

•	When running an engine in the repair stall for an extended period of time, use care not to overheat the engine and transmission.

2. When a test requires jacking up the vehicle and running with the wheels and brake drum removed:

•	Do not apply the brake with the brake drums removed.

•	Do not place the transmission in Park with the propeller shaft still spinning.

•	Turn off the ignition to stop the powertrain components from spinning.
