Braking and Hydraulic Fan System
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 attachments have been lowered, 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.
To relieve the pressure from the braking and hydraulic fan system, turn off the machine. Pump the brakes at least 110 times. Do not assume that all of the pressure is removed from the system because the brake pedal does not have resistance. Remove the pressure when you work on any part of the braking and hydraulic fan system.
