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.
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 and engage the parking brake.Stop the engine and remove the key.Block the wheels and install the steering frame lock.
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.

Pilot Valve (1) Pressure reducing valve (lift arm) (2) Pressure reducing valve (pilot oil) (3) Test portThe pilot valve is located inside the loader frame between the front wheels.Use the following procedure to test the pilot system pressure while the engine is running:
Shut off the engine.
Attach the hose and the pressure gauge to test port (3) .
Start the engine and allow the engine to run at high idle. At normal temperature, the pressure reading should be 3515 275 kPa (510 40 psi).
If the pressure reading is not correct, replace pressure reducing valve (2) with a new 114-1266 Pressure Reducing Valve .Use the following procedure to test the pilot system pressure while the engine is not running and the lift arms are raised:
Shut off the engine.
Attach the hose and the pressure gauge to test port (3) .
Start the engine.
Raise the lift arms off the ground.
Shut off the engine.
At normal temperatures, the pressure reading should be 2600 +500/-200 kPa ((380 +75/-30 psi)).
If the pressure reading is not correct, replace pressure reducing valve (1) with a new 114-1267 Pressure Reducing Valve .
