IMPORTANT INSPECTION ITEMS AFTER REASSEMBLING

a Operate the Kubota U15, U15-3 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 U15, U15-3 Operator’s Manual)
1) Park the machine on a level ground.
2) Make sure the hydraulic oil temperature is in the range of 10-30°C (50-86°F) and see if the oil level is within the specified zone of the oil level gauge.
3) Keep the machine front as shown as following posture.

1. Keep in mind that the battery voltage is applied through the above circuit all the time.
2. A 60A fuse is added close to the alternator, otherwise part of the harness may get short-circuited due to the alternator’s current generated while the engine is running. In this way, the devices and harness can be protected against burn-out.
