a Operate the Kubota KX36-3, KX41-3S, KX41-3V Excavator and check for Unusual Noise and Vibrations.
b Make Sure the Safety decals and Wire harness Clamps are in their Specified Positions.

c With the Machine Front in a Specified Posture, Check the Amount of Hydrauric Oil Checking the oil level (For further details, refer to the Excavator KX36-3, KX41-3S, KX41-3V Operators Manual)

1) Park the machine on a level ground.
2) Make sure the hydraulic oil temperature is in the range of 10-30C (50-86F) and see if the oil level is within the specified zone of the oil level gauge.

Checking and Adjusting the Excavator Engine Body
Compression Pressure
1. Run the engine until it is warmed up.
2. Stop the engine.
3. Remove the air cleaner, the muffler, the head cover and all glow plugs.
4. Set a compression tester (Code No. 07909-30208) with the adaptor (Adaptor K, code No. 07909-291) to the glow plug hole.
5. After making sure that the stop lever is set at the stop position (non-injection), run the engine with the starter and measure the compression pressure.
6. Repeat steps 4 and 5 for each cylinder.
7. If the measurement is below the allowable limit, apply a small amount of oil to the cylinder wall through the glow plug hole and measure the compression pressure again.
8. If the compression pressure is still less than the allowable limit, check the top clearance, valve clearance and cylinder head.
9. If the compression pressure increases after applying oil, check the cylinder wall and piston rings.Compression Pressure
