Personal injury or death can result from improper lifting or blocking. When a hoist or jack is used to lift any part or component, stand clear of the area. Be sure the hoist or jack has the correct capacity to lift a component. Install blocks or stands before performance of any work under a heavy component. Approximate weights of the components are shown. Clean all surfaces where parts are to be installed.

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.

1. Put identification marks on all hoses, and on all tubes for installation purposes. Plug all lines, all hoses, and all tubes. This will prevent fluid loss and contamination.

    Typical example

14. Attach a suitable nylon lifting sling around the wheel (18). Attach the nylon lifting sling to a suitable hoist in order to support the wheel. The weight of the wheel without ballast is approximately 190 kg (420 lb).

    Note: Liquid ballast is installed in the tires of certain machines. Liquid ballast will greatly increase the weight of a wheel. You must be sure that the weight of the wheel will not exceed the lifting capacity of your lifting equipment. Refer to Operation and Maintenance Manual, "Tire Inflation Information" for additional information about the recommended weight of installed liquid ballast.
