Sudden movement or accidental starting of the machine can cause personal injury or death to persons on or near the machine.To prevent personal injury or death, perform the following:Park the machine on a smooth level surface.Lower the bucket and or attachments to the ground.Stop the engine and engage the parking brake.Block the wheels and install the steering frame lock.Turn the battery disconnect switch to the OFF position and remove the key.Place a Special Instruction, SEHS7332, "Do Not Operate" tag at the battery disconnect switch location to inform personnel that the machine is being worked on.
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, 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.
Escaping fluid under pressure, even a pinhole size leak, can penetrate body tissue, causing serious injury, and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.Always use a board or cardboard when checking for a leak.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.

Before you make these checks, stop the engine and engage the parking brake. Shift the transmission direction and speed control to the NEUTRAL position (if equipped). Shift the transmission direction control switch to the NEUTRAL position (if equipped). During these checks, use a magnet to separate ferrous particles (iron) from nonferrous particles (O-ring seals, aluminum, bronze, etc), if necessary.
Check the oil level in the differentials.
Check the transmission oil level. Look for air bubbles in the oil or water in the oil. Many problems in the transmission are caused by low oil level or by air in the oil. Add oil to the transmission, if necessary. Refer to Operation and Maintenance Manual, "Lubricant Viscosities and Refill Capacities" for the recommended oil grade and the recommended oil viscosity.
Air bubbles may be caused by a fitting that is loose or damaged. A loose
