Position the machine on level ground.
Stop the engine.
Install tooling (C) on the engine.
Place track block (D) in the left travel sprocket to block left forward travel. Place track block (D) in the right travel sprocket to block right forward travel. Test Procedure
Start the engine.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Read the engine speed display (rpm) on the multi-tool. Refer to Table 1 for the specifications for engine speed at the desired engine operation. Travel Procedure
Use the following procedure to check the desired engine speed for travel operation.
Start the engine.
Place the hydraulic activation control lever in the UNLOCK position.
Increase the hydraulic oil temperature to 55° 5°C (131° 9°F).
Place the machine controls at the following settings: engine speed dial 10 and AEC switch OFF.
Place the travel speed control switch in HIGH position.
Move both travel levers to the full forward travel position and hold for 10 seconds. Read the engine speed display (rpm) on the multi-tool. The engine speed should slowly increase to 1800 50 rpm.
Return the travel levers to the NEUTRAL position.
