NOTICE
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting, and repair
of the product. Be prepared to collect the fluid with suitable containers
before opening any compartment or disassembling any component
containing fluids.

Refer to Special Publication, PERJ1017, "Dealer Service Tool
Catalog" for tools and supplies suitable to collect and contain fluids on
Cat®
products.
Dispose of all fluids according to local regulations and mandates.
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.
At operating temperature, the engine coolant is hot and under pressure.
Steam can cause personal injury.
Check the coolant level only after the engine has been stopped and the
fill cap is cool enough to touch with your bare hand.
Remove the fill cap slowly to relieve pressure.
Cooling system conditioner contains alkali. Avoid contact with the skin
and eyes to prevent personal injury.
