Case Wheeled Excavator WX148 Service Manual
Note to the Owner:
- The wheeled excavators are operation hydraulic machines. They essentially consist in a wheeled undercarriage on which a slewing bearing is mounted, which is coupled to the upper frame. The upper frame supports the front attachment, the engine, the hydraulic components, the cab, the fuel tank and the counterweight.
- When the operator activates the controls (hydraulic control levers and pedals), the hydraulic pumps rotated by the engine suck oil from the tank and convey it to the control valve, the control valve, in turn, sends it to the relevant users. A cooling system keeps the hydraulic fluid at a normal operating temperature.
Designated use:
The machine has been built in accordance with state-of-the-art standards and the recognized safety rules. The machine must be used in accordance with its designated use, by observing the safety and precautionary rules and by strictly following the operating instructions. Any functional disorders, especially those affecting the safety of the machine, should therefore be rectified immediately. The Excavator is intended to be used in digging and loading operation (with bucket or grab or clamshell bucket), ground levelling (with blade when installed) and use of hydraulic hammer to break concrete or other solid material.
Notice:
A different use of the excavator or of its working equipment:
• For lifting or transporting persons.
• As a working platform.
• For lifting loads without the attachment being approved for this purpose.
• For pulling slung loads.
• For driving in posts, supports, sheet-piles, without the attachment being approved for this purpose.
