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, NENG2500, "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.
At operating temperature, the hydraulic oil is hot and under pressure.
Hot oils can cause burns.
To prevent possible personal injury, release the pressure in the work
tool hydraulic circuit (boom, stick, bucket, and swing), travel circuits,
and the hydraulic oil tank at the filler cap before any hydraulic lines or
components are disconnected or removed.
Remove the filler cap only when the engine is stopped and the filler cap
is cool enough to touch.
