ADAPTER 0844076 - Caterpillar

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 work tools have been lowered to the ground, 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: The signal relief valves must be set to the correct specification before the flow rate can be tested. Refer to Testing and Adjusting, "Relief Valve (Signal) - Test and Adjust".Note: The line relief valves for the rotate control valve are preset at a specific pressure. The line relief valves are not adjustable.

Start the engine.
Place the machine controls at the following settings: engine speed dial "10" and AEC switch OFF. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for engine rpm settings.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Put the hydraulic activation control lever in the UNLOCKED position. Depress the device for activation for clockwise rotation.
Record the flow rate.Note: The flow rate is adjusted by limiting the spool travel by using adjustment screws (21) and (23) .
