ENGINE AR-PRIMARY 1358589 - Caterpillar

Diesel engine exhaust contains products of combustion which may cause personal injury.Always start and operate the engine in a well ventilated area, and, if in an enclosed area, vent the exhaust to the outside.
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 or death can result from sudden machine movement.Sudden movement of the machine can cause injury to persons on or near the machine.To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating 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.
