Personal injury can result from rotating and moving parts. Stay clear of all rotating and moving parts. Never attempt adjustments while the machine is moving or the engine is running unless otherwise specified. The machine must be parked on a level surface and the engine stopped. Attach a "Do Not Operate" or similar warning tag to the start switch and controls before servicing, repairing, or making adjustments to the machine.

Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.

Note: Park the machine on soft dirt or place tires under the drums. Alternately, the machine can be lifted onto jacks, and the machine drums may be supported by air bags. The weight of the machine is approximately 11440 kg (25,220 lb).

Note: The machine is equipped with two vibratory motors. One vibratory motor is located on the left side of the front drum. The second vibratory motor is located on the right side of the rear drum. The following procedure illustrates the test on the rear vibratory motor. The same procedure can be used to test the front vibratory motor.

1. Drive the machine to a smooth, horizontal surface.
