Start By:
a.Release the hydraulic system pressure.
Personal injury can result from hot coolant, steam and alkali.
At operating temperature, engine coolant is hot and under pressure. The
radiator and all lines to heaters or the engine contain hot coolant or
steam. Any contact can cause severe burns.
Remove cooling system pressure cap slowly to relieve pressure only
when engine is stopped and cooling system pressure cap is cool enough
to touch with your bare hand.

4.Remove sheet assembly (1), hose (2), coolant tank (3), and guard assembly (4).
Do not attempt to tighten hose connections when the coolant is hot, the
hose can come off causing burns.
Cooling System Coolant Additive contains alkali. Avoid contact with
skin and eyes.
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.Turn the battery disconnect switch to the OFF position.
2.Refer to Operation and Maintenance Manual, "Cooling System Coolant - Change" for the
correct draining and filling procedures.
3.Drain the hydraulic oil. Refer to Operation and Maintenance Manual, "Hydraulic System Oil -
Change" for correct draining and filling procedure.
