WARNING!
The hydraulic oil will be hot after normal machine
operation. Allow the system to cool before attempting to
service any of the hydraulic components.
The hydraulic tank is pressurized. Loosen the hydraulic
breather cap slightly to allow the pressurized air to vent.
After the pressure has been released, it is safe to remove
either the fill cap or service covers or drain water from the
tank.
